Hemp Cosmetics: CBD Cream, Serum and Balm - Do They Really Work on the Skin

On the label of a hemp cosmetic, you will rarely find a number that would allow you to assess what you are actually buying. There may be Cannabis Sativa Seed Oil, which is oil pressed from seeds, in which cannabinoids are practically absent. There may be Cannabidiol, but without a specified amount. None of these ingredients has a study measuring wrinkles without the involvement of another active substance. This difference determines what you are paying for, and cosmetic regulations do not require the manufacturer to explain it. In this article, we separate both ingredients, check how much cannabidiol actually penetrates the stratum corneum, and show what the research says about acne, psoriasis, atopic dermatitis, and wrinkles. You will also learn the differences between serum, cream, and balm, why the carrier matters more than the declared concentration, and what to check on the ingredient list before you take out your wallet.

KEY INFORMATION
• The cannabinoid content in commercial hemp seed oils is variable and cannot be relied upon as a source of cannabidiol (Citti et al., Frontiers in Plant Science, 2019).
• In excised human skin, the best of the studied formulations delivered 5.25 percent of the applied CBD to the skin, and ready-made cosmetics performed worse (Lapteva et al., Pharmaceutics, 2024).
• The work of Oláh from 2014, cited as evidence for acne, is a culture of human sebocytes and skin, not a study on patients.
• Of the 80 tested CBD products, 37 deviated from the label by more than 10 percent (Johnson et al., Journal of Cannabis Research, 2022).

What is the difference between hemp seed oil and CBD in a cosmetic composition?

These are two different ingredients. Cannabis Sativa Seed Oil is oil pressed from seeds, rich in omega-3 and omega-6 fatty acids, in which cannabidiol is practically absent. CBD is listed on the INCI list as Cannabidiol or as an extract from leaves or flowers. A product may contain one, the other, or both at the same time.

The reason is botanical. Cannabinoids are produced in glandular hairs on flowers and leaves, not in seeds; they reach the oil from plant material during harvesting and pressing. Citti et al. examined ten commercial seed oils using mass spectrometry and described 30 other cannabinoids alongside THC and cannabidiol, for the first time in this raw material. The composition varied significantly between samples (Frontiers in Plant Science, 2019). Trace amounts may be present, but they cannot be relied upon as a source of the active substance.

This does not mean that seed oil is worthless. It is a good emollient, and its effect on the skin has been studied independently of cannabinoids: in Callaway et al. (Journal of Dermatological Treatment, 2005), a twenty-week diet with hemp oil reduced dryness and itching in atopic dermatitis. The fatty acids were effective there.

Does CBD penetrate the skin and how deep?

It penetrates, but poorly and superficially. Cannabidiol is highly lipophilic, so it tends to remain in the stratum corneum rather than travel further. How much reaches the living layers depends more on the carrier than on the declared concentration in the product.

The first measurements on excised human skin were performed by Stinchcomb et al. (Journal of Pharmacy and Pharmacology, 2004). The permeability for cannabidiol was found to be ten times higher than for delta-8-THC, and the flow through the skin significantly increased only after adding ethanol at a concentration of 30 to 33 percent. The substance alone is not enough; a penetration enhancer is needed.

Newer works show how important the base is. Casiraghi et al. (Pharmaceuticals, 2020) compared four solutions and two semi-solid formulations on human skin in Franz cells. They considered a hydrophilic gel composed of 79 percent propylene glycol to be the optimal carrier. Lapteva et al. (Pharmaceutics, 2024) measured how much cannabidiol remains in the skin: the most effective of the studied colloidal gels delivered 5.25 percent of the applied amount, and two ready-made cosmetics from the market performed worse than the experimental formulations, including the aqueous solution.

We noticed that the claim about an oily base being the best carrier for cannabidiol is repeated in descriptions of hemp cosmetics. However, in both of these measurements, water and glycol carriers won, so the claim has no basis in them. It is also useful to distinguish between what advertisements blur: a topical preparation is supposed to work in the skin, while a transdermal one transfers the substance into the bloodstream and requires a patch. A store-bought cosmetic is a topical preparation.

What do cannabinoid receptors do in the skin?

The skin has its own endocannabinoid system. CB1 and CB2 receptors and TRPV family channels are present in keratinocytes, fibroblasts, Langerhans cells, and sebocytes (Bíró et al., Trends in Pharmacological Sciences, 2009). This system co-regulates the proliferation of epidermal cells, sebum production, and the inflammatory response.

This explains why cannabidiol is even considered as a cosmetic ingredient. However, this is not proof that it works straight from the package. The presence of a molecular target in the skin and the effectiveness of a finished product are two different things, separated by the penetration problem described above.

The mechanism itself is often described incorrectly. Wilkinson and Williamson (Journal of Dermatological Science, 2007) tested four phytocannabinoids on a line of excessively proliferating human keratinocytes. All inhibited proliferation depending on the concentration, but antagonists of CB1 and CB2 receptors did not block this effect, so the popular explanation of action through CB1 in psoriasis does not correspond to the data.

What are the differences between hemp serum, cream, and balm?

They differ primarily in the ratio of water to fat, not in the depth of cannabidiol penetration. Serum is light and absorbs quickly, cream is a moisturizing emulsion, and balm is thick and reduces water loss through the epidermis. The declared form says nothing about the CBD content.

The popular order, serum before cream and balm at the end, results from the density of the preparations, not from studies on cannabidiol. The principle is: from the thinnest to the thickest, because an occlusive layer applied first hinders the absorption of subsequent products.

In practical retail, under the banner of hemp cosmetics, you will find both types of products: those with only hemp seed oil and those that additionally declare cannabidiol. The trade name with hemp in the background does not determine which group a given product belongs to. The ingredient list does.

Does a CBD cosmetic work for acne?

There is no evidence for this in humans. The most frequently cited work, Oláh et al. (Journal of Clinical Investigation, 2014), is a study on cultured human sebocytes and skin in organ culture, not on patients with acne. It showed that cannabidiol inhibits lipogenesis through TRPV4 channels.

The results are mechanistically strong. Cannabidiol reduced sebocyte proliferation and suppressed the inflammatory response through the adenosine A2a receptor-dependent pathway. Later works followed the same path: Lee et al. (Archives of Dermatological Research, 2024) worked on SEB-1 sebocyte cell lines and HaCaT keratinocytes.

So, over the decade, mechanisms have increased, but not studies on patients. The review by Kuzumi et al. (American Journal of Clinical Dermatology, 2024) summarizes it unequivocally: there have been very few clinical studies on cannabidiol in the skin, and a separate problem remains the delivery of the substance deep into the epidermis.

Acne is a dermatological diagnosis with documented effective treatments. Topical retinoids, benzoyl peroxide, or isotretinoin in severe forms have studies behind them that a cannabidiol cosmetic does not. Delaying a visit to a dermatologist for inflammatory changes increases the risk of acne scars, which no cream will remove.

What is known about CBD for psoriasis and atopic dermatitis?

Very little, mainly from small studies without a control group. No randomized placebo-controlled study has been published for a cannabidiol cosmetic in psoriasis or atopic dermatitis. Retrospective case series and pilot studies on a few people are available.

The most frequently cited work is that of Palmieri et al. (Clinica Terapeutica, 2019), sometimes described as a clinical study on twenty patients with AD. In reality, it is a retrospective analysis of twenty people without a control group, of which only five had psoriasis, five atopic dermatitis, and the remaining ten had scars. After three months, hydration, transepidermal water loss, and PASI score improved. However, without a placebo, it is impossible to separate the effect of cannabidiol from that of the ointment base itself.

Similar limitations apply to the pilot study by Burczyk et al. (Clinical, Cosmetic and Investigational Dermatology, 2025): nine people with AD, a compounded ointment with 30 percent cannabidiol and 5 percent cannabigerol, improvement in hydration, sebum levels, and erythema. Such concentrations do not occur in over-the-counter cosmetics.

The only randomized double-blind study published so far in psoriasis concerned the oral route and yielded negative results on the primary endpoint. Roongpisuthipong et al. (Journal of Dermatological Treatment, 2026) administered 60 mg of cannabidiol daily or placebo to 28 people. The PASI score did not improve significantly, although less itching was noted in the eighth week and shorter sleep onset in the sixth, with the latter effect not being maintained.

Psoriasis and AD are chronic diseases with confirmed effective treatments: emollients, topical glucocorticoids, calcineurin inhibitors, and in severe psoriasis, systemic therapy. A hemp cosmetic may support the care of dry skin between flare-ups, but independently discontinuing treatment prescribed by a dermatologist has no basis in the data. What dermatology says separately about atopic dermatitis, we have gathered in the text about CBD oil for AD.

How much cannabidiol does a cosmetic contain and how to check it?

Usually, it cannot be determined from the label. There is no study determining the minimum effective concentration of cannabidiol in a cosmetic, and cosmetic regulations do not require stating the amounts of individual ingredients. Without milligrams on the packaging, you have nothing to compare.

The circulating thresholds online, such as 250 to 350 mg per 30 ml of product, sound precise, but they do not come from any scientific work. We found no source for them and therefore removed them from this text. A number without a study behind it is worse than its absence, as it looks like knowledge.

A separate problem is the compliance of declarations with the actual state. Johnson et al. (Journal of Cannabis Research, 2022) examined 80 cannabidiol products available for sale using LC-MS/MS. Declarations ranged from 7.5 to 60 mg/ml, while measurements ranged from 2.9 to 61.3 mg/ml. Thirty-seven products deviated from the label by more than 10 percent, with twelve containing less than 90 percent of the declaration and twenty-five above 110 percent.

What to do when purchasing? Check where on the INCI list Cannabidiol is located, as ingredients are listed in descending order of concentration. Look for the content stated in milligrams on the packaging, not just the hemp claim. Also, ask for a certificate of analysis; we discuss how to read it in the article How to read a CBD certificate. The lack of such data is a market standard, not proof of fraud.

Does CBD balm relieve muscle and joint pain?

The data is preliminary and comes from outside cosmetics. Hammell et al. (European Journal of Pain, 2016) applied a transdermal gel to rats with knee joint inflammation. Swelling and infiltration of inflammatory cells decreased depending on the dose, with 6.2 and 62 mg per day being effective. This is an animal model, not a cosmetic.

In humans, there is one small randomized study. Xu et al. (Current Pharmaceutical Biotechnology, 2020) compared cannabidiol oil applied topically to placebo in 29 people with peripheral neuropathy of the lower limbs for four weeks. The preparation contained 250 mg of cannabidiol in about 90 ml. In the CBD group, the severity of acute and stabbing pain and sensations of cold and itching decreased, with no adverse events reported. However, this concerns neuropathy, not post-workout soreness.

We also noticed that massage gels with hemp usually contain menthol, camphor, or cinnamon oil. The cooling or warming sensation that occurs after a few seconds of massaging comes from them and would occur even without cannabidiol. Persistent joint pain requires diagnosis, as such a symptom may indicate an inflammatory disease requiring treatment.

Do hemp oil and CBD smooth out wrinkles?

It is unknown, as no one has measured this separately. There is no work that has tested hemp seed oil alone or cannabidiol alone for wrinkles against a comparative group. Two studies in which wrinkles were measured concerned complex preparations, and alongside cannabidiol, they contained an ingredient with its own research background.

Few et al. (Aesthetic Surgery Journal Open Forum, 2022) administered a cream with 300 mg of cannabidiol and 0.2 percent retinol to ten people for 42 days, without a control group. Static and dynamic wrinkles were assessed better afterward, but retinol is an anti-wrinkle substance with documented effects. Cohen et al. (Journal of Cosmetic Dermatology, 2023) studied a gel with cannabidiol and eicosapentaenoic acid in 33 people for 56 days and measured a smaller area of crow’s feet. Again, two ingredients at once.

The only one of these trials with a comparative arm did not measure wrinkles. McCormick et al. (Journal of the American Academy of Dermatology, 2024) compared a cream with nanoencapsulated cannabidiol to the base alone, on the skin of the buttock, and after UV-A exposure found less DNA damage and less epidermal thickening. This is an indication of protection against radiation, not a measurement of facial smoothing.

Hemp seed oil does as much as any good emollient: it replenishes lipids and reduces dryness, and hydrated skin has shallower surface lines as long as it is hydrated. Most wrinkles are caused by sunlight, and evidence from a randomized trial has photoprotection there: Hughes et al. (Annals of Internal Medicine, 2013) observed 903 people for 4.5 years and counted 24 percent fewer signs of photoaging in those who used sunscreen daily compared to those who used it occasionally. How to use hemp cosmetics after sun exposure is described in the text about CBD for sunburns.

What to watch out for with hemp cosmetics?

For three things: lack of sun protection, the possibility of allergies, and the temptation to discontinue treatment. Cannabidiol does not absorb UV radiation, so a cream with hemp does not replace a sunscreen product. When used in the morning, it should be supplemented with photoprotection.

Allergic reactions have also been described for hemp seed oil itself. Clark et al. (Contact Dermatitis, 2022) presented a case of allergic contact dermatitis caused by this ingredient. However, a more common source of irritation is often fragrance additives and essential oils. Before first use of a new cosmetic, apply a small amount to the inner side of your forearm and wait a day.

Do not apply hemp cosmetics to damaged skin, weeping lesions, or fresh wounds. During pregnancy, breastfeeding, and with skin disease in the exacerbation phase, introducing a new preparation is better discussed with the attending physician. If burning, itching, or redness occurs after a few days of use, discontinue the product instead of waiting for the skin to get used to it.

The last thing concerns expectations. A cosmetic with cannabidiol may improve the comfort of dry and irritated skin, as any well-composed emollient does. If the manufacturer promises to cure a diagnosed skin disease, they are promising something that the data does not support, and cosmetic regulations explicitly prohibit attributing therapeutic effects to cosmetics.

Frequently Asked Questions

Is cream with hemp seed oil the same as CBD cream?

No. Cannabis Sativa Seed Oil is oil pressed from seeds, rich in fatty acids, but seeds do not produce cannabinoids. Cannabidiol appears on the INCI list as Cannabidiol or as an extract from leaves or flowers. The cosmetic may contain only seed oil, only cannabidiol, or both ingredients at the same time.

How much CBD should a cream contain to be effective?

No such value has been established. There is no study determining the minimum effective concentration of cannabidiol in a cosmetic, and the thresholds circulating online, such as 250 mg per 30 ml, have no basis in the literature. The only thing you can do is compare products that state the content in milligrams on the packaging.

Does CBD from the cream enter the bloodstream?

In practice, not in significant amounts. Cannabidiol is lipophilic and remains in the stratum corneum. In a measurement on excised human skin, the best of the studied formulations delivered 5.25 percent of the applied dose to the skin (Lapteva et al., Pharmaceutics, 2024). The cosmetic product works locally, not systemically.

Will a CBD cosmetic cure acne?

No. The work of Oláh et al. (Journal of Clinical Investigation, 2014), cited by manufacturers, is a study on cultured human sebocytes and skin in organ culture, not on patients. Acne is treated with topical retinoids, benzoyl peroxide, or isotretinoin, and cosmetics do not replace them.

Can hemp cosmetics cause allergies?

They can. Allergic contact dermatitis caused by hemp seed oil itself has been described (Clark et al., Contact Dermatitis, 2022). However, a more common source of irritation is often essential oils added to massage gels, such as menthol, camphor, or cinnamon oil. Before first use, do a patch test on your forearm.

Can CBD oil for oral use be applied to the skin?

Yes, but it is not the same product as a cosmetic. The oil in MCT carrier does not have emulsifiers, pH regulators, or a preservative system intended for the skin. It can be used temporarily as an emollient for a dry spot, not as a daily facial care product.

How long does it take to assess the effect of a CBD cosmetic?

Studies of topical preparations with cannabidiol lasted from four weeks (Xu et al., 2020) to three months (Palmieri et al., 2019). A reasonable observation period for a cosmetic is 8 to 12 weeks of regular use. If nothing changes during this time, changing the product makes more sense than increasing the amount.

Hemp cosmetics available at Bucha can be found in the hemp cosmetics section, and oral preparations in the hemp oils section. For each, check the ingredient list to see if Cannabidiol is listed or only Cannabis Sativa Seed Oil.
