Serum

Serum is concentrated care that penetrates deeper than cream and works faster than a mask. In this category, you will find hemp serum, CBD face serum, vitamin serums, and specialized serums for hair and scalp — all available in one place at ubucha.pl. If you are looking for a product that truly supports your complexion, scalp, or feet, rather than just providing surface hydration, you are in the right place. On this page, you will learn how different types of serums vary, how to choose them according to your skin's needs, and how to use them to get the most out of them.

How to choose a serum? A guide to types and ingredients

Serum is not a single product — it is a category with a very wide range of effects. According to market data from Mintel, face serums are one of the fastest-growing segments in the cosmetics market in Europe, with an annual sales growth of about 8–10%. Their popularity is due to their concentrated formula: the active molecules are smaller than those in creams, allowing them to penetrate deeper into the epidermis.

When choosing a serum, pay attention to six key criteria:

• Type of skin problem. Serum with CBD and hemp oil (like PALACIO Regenerating and Moisturizing Serum) is suitable for sensitive, reactive, and dry skin. Serum with hyaluronic acid (like PALACIO Lifting Gel) targets loss of hydration and elasticity.
• Composition and certifications. Organic serums have a higher content of natural ingredients — for example, PALACIO Vitamin Serum from Hemp contains 98% natural origin ingredients. An organic certificate or vegan formula are signs of quality.
• Concentration of active ingredients. In CBD serums, it's worth checking whether the CBD comes from full-spectrum extract or isolate. In vitamin serums — which vitamins and in what form: vitamin C in the form of ascorbic acid is less stable than its derivatives.
• Consistency and absorption. Light gel serums (e.g., lifting gel with hyaluronic acid) work well for combination and oily skin. Thicker oil or cream serums are suitable for dry skin.
• Area of application. Face serums and hair serums are separate products with different formulas. Scalp serums (Capillus with caffeine, Capillus Seborea) act on the hair follicles and scalp, not on the hair surface.
• Price per ml, not per package. Bio serum cannabellum 30 ml for 36 zł is a different calculation than vitamin serum PALACIO 50 ml for 31 zł. Calculate the cost of use, especially with daily application.

Two mistakes that buyers make. First: applying serum after cream — this is the opposite of the correct order. Serum should always be applied to cleansed skin before the cream. Second: expecting immediate results. Serum works cumulatively — the first visible effects appear after 4–8 weeks regular use.

Who is this for: Serum is a product for anyone looking to enhance their skincare routine beyond a basic moisturizer. It is particularly effective for demanding skin — dry, reactive, showing signs of aging, or with seborrheic issues.

Who it is NOT for: If you are just starting your skincare journey and looking for one facial product, begin with a good cream. Serum is the second step, not the first.

Products available in the serum category

At u Bucha, we have gathered serums with various profiles — from hemp formulations with CBD, to specialized serums with snake venom and snail extract, to serums for hair and foot care. Below, we discuss each product individually.

Hemp and CBD face serum

PALACIO Regenerating and Moisturizing Face Serum 50 ml (36 zł) is a vegan and organic product, with cold-pressed hemp seed oil and CBD extract. The formula supports the skin's protective barrier, absorbs quickly, and does not leave a greasy film — a plus for sensitive skin that cannot tolerate heavy products. Dermatologically tested.

PALACIO Vitamin Serum with Hemp 50 ml (31 zł) combines CBD with cold-pressed hemp oil and a set of vitamins: C, A, E, D, and B. The formula contains 98% natural ingredients, free from parabens, for the face, neck, and décolletage. Vitamin C supports collagen production, while vitamin E has antioxidant properties — together they delay visible signs of skin aging.

cannabellum CBD Face Serum 50 ml (41 zł) is an offering from the cannabellum brand — it regenerates and moisturizes the skin, with CBD as the main active ingredient. The 50 ml formula is suitable for daily care.

cannabellum CBD Bio Serum 30 ml (36 zł) is a smaller package from the same brand, with a certified bio formula. It intensely regenerates and moisturizes the facial skin — 30 ml is enough for several weeks of regular use.

Serum with specialized active ingredients

PALACIO Anti-Wrinkle Serum with Snake Venom 50 ml (36 zł) utilizes the peptide SYN-AKE, a synthetic analog of snake venom, which works similarly to botulinum — temporarily relaxing facial muscles, reducing fine lines. Studies from 2012 confirm the effectiveness of peptides from this group in reducing wrinkles by up to 52% after 28 days of use. The product is intended for daily facial care.

PALACIO Serum with snail extract 50 ml (34 zł) contains snail mucin — an ingredient known from Korean skincare, rich in glycoproteins, allantoin, and glycolic acid. It supports skin renewal, soothes irritations, and aids in healing minor imperfections.

PALACIO Lifting Gel with hyaluronic acid 50 ml (34 zł) is a gel formula, lighter than classic serums — it firms and hydrates thanks to hyaluronic acid, which binds water in the skin. It works well as a moisturizing step before cream, especially for combination skin.

Hair and scalp serum

Capillus Serum with caffeine 40 ml (56 zł) stimulates hair follicles and prevents excessive hair loss. Caffeine affects microcirculation of the scalp — according to studies published in IJCS it penetrates hair follicles within 2 minutes of application. A product for those with hair loss issues.

Capillus Seborea Serum 50 ml (49 zł) is a serum for seborrheic issues: irritations, itching, flaking of the scalp. The soothing formula regulates sebum production and strengthens hair — suitable for those with symptoms of atopic dermatitis or scalp psoriasis.

Specialized foot care serum

Serum Mycosin 12 ml (38.50 zł) is care for dry, itchy, and sensitive foot skin prone to fungal infections. The slightly acidic pH of the formula soothes redness and irritation — it absorbs quickly and does not leave a greasy layer.

How to use serum? Step by step

The serum works only when applied correctly — the order of steps matters. Below is a simple protocol that applies to both facial serums and hair serums (with a slight modification for application).

1. Cleanse the skin. Apply the serum only on freshly cleansed skin — without remnants of makeup, creams, or SPF from the previous day. A contaminated surface blocks the absorption of active ingredients. A gentle gel or milk is sufficient for cleansing.
2. Optional: toner or essence. If you are using a moisturizing toner or essence, apply them before the serum — lighter formulas always go before heavier ones.
3. Measure the appropriate amount of serum. For the face, a few drops or a pea-sized amount is sufficient. A larger amount does not speed up the effects — excess does not absorb deeper, but remains on the surface of the skin.
4. Apply with gentle patting motions. Warm the serum between your fingers and press your hands to your face, then spread it evenly. Avoid rubbing — the facial skin is delicate. For hair serum: apply directly to the scalp, not along the length of the hair.
5. Wait a moment before the next step. The serum needs a few seconds to penetrate the skin. Then apply a moisturizer or SPF — the cream seals the serum and prevents the evaporation of active ingredients.
6. Use regularly, morning or evening. Vitamin serum with vitamin C is used in the morning (antioxidant protection). Serum with retinol or strong peptides — in the evening. Moisturizing serum can be used at any time. Effects are visible with regular use for a minimum of 4–6 weeks.

Who is the hemp and CBD serum for?

CBD and hemp oil serum works in specific situations — it is not a product suitable for every skin type without exception. Hemp oil has the ratio of omega-6 to omega-3 close to 3:1, which makes it one of the most balanced plant oils used in cosmetics. CBD, on the other hand, exhibits soothing and antioxidant properties described in studies on reactive skin.

Who benefits the most from hemp serum:

• Dry and dehydrated skin — hemp oil moisturizes and strengthens the lipid barrier of the epidermis.
• Sensitive and reactive skin — CBD and hemp ingredients have soothing effects, reducing redness.
• Skin with the first signs of aging — vitamin formulas with CBD support collagen production and protect against free radicals.
• People who prefer natural and vegan cosmetics — hemp serums often have organic certifications, and formulas free from parabens and silicones.

Who hemp serum may not be the best choice for:

• Oily and acne-prone skin — hemp oil is non-comedogenic, but some formulas with additional oils may exacerbate oiliness.
• People allergic to plants from the Cannabaceae family — it is advisable to perform a patch test on a small area of skin before use.

You can read more about the properties of CBD and its effects on the body in the article about storing CBD oil — the rules regarding the stability of active ingredients are similar for cosmetic products with CBD.

Safety and contraindications

Serums are cosmetic products, not medications — they are not required to go through medical registration processes. Nevertheless, it is worth following a few rules that minimize the risk of skin reactions.

Before applying a new serum to your entire face, always perform a patch test: apply a small amount of the product behind your ear or on your wrist and wait 24–48 hours. This is a standard procedure recommended by dermatologists, especially with products containing new active ingredients — such as snail extract, snake venom, or CBD.

A few additional tips:

• Vitamin C serum may cause slight burning during the first applications — this is a normal reaction at higher concentrations. If irritation does not subside after a few days, reduce the frequency of use.
• Serum with acids (like hyaluronic acid in lifting gel) require the use of SPF cream during the day — acids increase skin sensitivity to light.
• Hair serum with caffeine (Capillus) are intended solely for the scalp — not for the face or eyes.
• Pregnancy and breastfeeding: when using products with CBD, it is advisable to consult a dermatologist, even for external use.
• Storage: serums with vitamin C and CBD are sensitive to light and heat. Store in a dark, cool place — preferably in the refrigerator after opening.

Frequently asked questions

What is the difference between serum and face cream?

Serum has smaller active molecules and a higher concentration of ingredients than cream — this allows it to penetrate deeper into the epidermis. Cream works on the surface: it moisturizes, protects, and seals. Serum and cream are used together, in the order: serum first, cream second. Serum without cream can lead to the evaporation of active ingredients.

Does hemp serum contain THC?

Hemp serums available in Poland must meet legal requirements — the THC content in cosmetics is regulated. The products in our offer (PALACIO, cannabellum) are based on CBD and hemp seed oil, which do not contain psychoactive THC above permissible limits. If you have doubts, check the product composition in the manufacturer's tab.

How often should face serum be used?

Most moisturizing and regenerating serums (with CBD, with hyaluronic acid, with snail extract) can be used twice a day — in the morning and evening. Serums with strong acids or retinol should only be used in the evening and not every day at the beginning. The first noticeable effects are visible after 4–8 weeks regular use.

In what order should serum and other skincare steps be applied?

The correct order is: cleansing, toner (optional), serum, moisturizer, and in the morning, finish with SPF. Serum always before cream — the logic is simple: lighter formulas go first, heavier ones seal the care. The reversed order prevents serum ingredients from reaching the skin. You can find more about CBD skincare protocols in the article on storing CBD.

Is snake venom serum safe?

Yes — serums with "snake venom" in cosmetics contain the synthetic peptide SYN-AKE, not real venom. The peptide mimics the action of the toxin from the snake venom Waglerin-1, relaxing facial muscles. Clinical studies confirm a reduction in wrinkles by up to 52% after 28 days of use. The product does not cause allergic reactions more frequently than other peptide serums.

Does caffeine hair serum really help with hair loss?

Caffeine blocks DHT (dihydrotestosterone) — a hormone responsible for the miniaturization of hair follicles in androgenetic alopecia. Studies published in the International Journal of Dermatology confirm that caffeine penetrates hair follicles and extends the hair growth phase. The effects require regular use for at least 3 months.

How long does a bottle of serum last with daily use?

With a few drops a day on the face, a standard-sized package lasts for several months. cannabellum CBD Bio Serum 30 ml this smaller package — lasts for about one and a half to two months. Serum Mycosin 12 ml for the feet, applied spot-wise on affected areas, can last for several months with occasional use.

Can hemp serum be combined with other active ingredients?

Yes — CBD and hemp oil are gentle and work well with hyaluronic acid, niacinamide, and vitamin E. Caution is advised when combining with AHA/BHA acids and retinol: they may enhance each other's effects or irritate the skin. General rule: do not combine several strong active ingredients in one routine until you know how your skin reacts.
