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 serum, and specialized serum 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 moisturizing superficially, you are in the right place. On this page, you will learn about the differences between the various types of serums, 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

A 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 cosmetics in Europe, with an annual sales growth of about 8–10%. Their popularity is due to the concentrated formula: active molecules are smaller than 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.
• Ingredients and certifications. Organic serums have a higher proportion of natural ingredients — for example, PALACIO Vitamin Serum with Hemp contains 98% natural ingredients. An ecological certificate or vegan formula are quality signals.
• Concentration of active ingredients. In CBD serums, check 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. A light gel serum (e.g., lifting gel with hyaluronic acid) works 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 hair follicles and the scalp, not on the hair surface.
• Price per ml, not per package. Bio cannabellum serum 30 ml for 36 PLN is a different calculation than PALACIO vitamin serum 50 ml for 31 PLN. Calculate the cost of use, especially with daily application.

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

Who it is for: serum is a product for anyone who wants to deepen their skin care 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 routine and looking for one product for your face, start with a good cream. Serum is a second step, not the first.

Products available in the serum category

u Bucha, we have gathered serums with various profiles of action — from hemp formulas with CBD, through 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 serums

PALACIO Regenerating and Moisturizing Serum for Face 50 ml (36 PLN) 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 — this is an argument for sensitive skin that does not tolerate heavy products. Dermatologically tested.

PALACIO Vitamin Serum with Hemp 50 ml (31 PLN) 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, and vitamin E has antioxidant properties — together they delay visible signs of skin aging.

cannabellum CBD Face Serum 50 ml (41 PLN) is a proposal 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 PLN) is a smaller package of 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.

Serums with specialized active ingredients

PALACIO Anti-Wrinkle Serum with Snake Venom 50 ml (36 PLN) utilizes the peptide SYN-AKE, a synthetic analogue 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 PLN) 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 PLN) is a gel formula, lighter than classic serums — it firms and moisturizes thanks to hyaluronic acid, which binds water in the epidermis. It works well as a moisturizing step before cream, especially for combination skin.

Hair and scalp serums

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

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

Specialized foot care serums

Mycosin Serum 12 ml (38.50 PLN) is 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

Serum works only when applied correctly — the order of steps matters. Below is a simple protocol that applies to both face serums and hair serums (with a slight modification when applying).

1. Cleanse the skin. Apply serum only to 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 use a moisturizing toner or essence, apply it before the serum — lighter formulas always go before heavier ones.
3. Measure the right amount of serum. A few drops or a pea-sized amount is enough for the face. A larger amount does not speed up effects — excess does not absorb deeper, it just remains on the skin’s surface.
4. Apply with gentle rubbing motions. Warm the serum between your fingers and place your hands on your face, then spread it evenly. Avoid rubbing — the facial skin is delicate. For hair serum: apply directly to the scalp, not to the length of the hair.
5. Wait a moment before the next step. 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 at least 4–6 weeks.

For whom hemp and CBD serum is suitable

Serum with CBD and hemp oil works in specific situations — it is not a product for every skin type without exception. Hemp oil has a ratio of omega-6 to omega-3 fatty acids close to 3:1, making 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. If you are interested in the wide application of hemp in skincare, read also our guide to hemp.

For whom hemp serum works best:

• 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 ecological certifications, formulas free from parabens and silicones.

For whom hemp serum may not be the best choice:

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

More about the properties of CBD and its effects on the body can be read 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 medicines — 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 the entire face, always do a patch test: apply a small amount of the product behind the ear or on the wrist and wait 24–48 hours. This is a standard procedure recommended by dermatologists, especially for products with 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.
• Acid serums (like hyaluronic acid in the lifting gel) require the use of a cream with SPF during the day — acids increase the skin’s photosensitivity.
• Caffeine hair serum (Capillus) is intended only for the scalp — not for the face or eyes.
• Pregnancy and breastfeeding: with products containing CBD, it is advisable to consult a dermatologist, even with external use.
• Storage: vitamin C and CBD serums 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 I use face serum?

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 are used only in the evening and not daily at first. The first noticeable effects are visible after 4–8 weeks of regular use.

In what order should I apply serum and other skincare steps?

The correct order is: cleansing, toner (optional), serum, moisturizer, and in the morning, SPF at the end. Serum always before cream — the logic is simple: lighter formulas go first, heavier ones seal the care. The reversed order means that serum ingredients do not reach the skin. More about skincare protocols with CBD can be found in the article on storing CBD.

Is snake venom serum safe?

Yes — “snake venom” serum in cosmetics contains the synthetic peptide SYN-AKE, not real venom. The peptide mimics the action of the toxin from the Waglerin-1 snake venom, relaxing facial muscles. Clinical studies confirm a reduction in wrinkles of 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) — the hormone responsible for the miniaturization of hair follicles in androgenetic hair loss. Studies published in the International Journal of Dermatology confirm that caffeine penetrates hair follicles and prolongs the hair growth phase. Effects require regular use for at least 3 months.

How long does a serum package last with daily use?

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

Can I combine hemp serum 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.
