Active ingredients are the heart of every cosmetic—they're responsible for visible results and improved skin condition. In this article, we answer the most important questions about the most popular active ingredients—how they work, who they're recommended for, and how to combine them for effective and safe skincare!
What are active ingredients and how do they work?
Active ingredients are substances with documented effects on the skin—hydrating, regenerating, brightening, stimulating collagen production, and soothing irritation. Unlike base ingredients (water, emulsifiers, preservatives) that stabilize the formula, active ingredients directly impact the skin's condition. Their effectiveness depends on concentration, stability, and application method.
How to distinguish basic ingredients from active ingredients?
The base ingredients are water, emulsifiers, thickeners, and preservatives – they have no effect on the skin but create the cosmetic's structure. The active ingredients are vitamins, acids, peptides, and ceramides – are responsible for the care effects.
What functions do they perform in facial and body care?
Active ingredients have various functions: they moisturize (hyaluronic acid), regenerate (retinoids, peptides), brighten (vitamin C, arbutin), soothe (panthenol, allantoin), rebuild the barrier (ceramides) and protect against aging (antioxidants).
How to choose active ingredients for your skin type and needs?
The choice of active ingredients depends on skin type and its concerns. Oily skin needs niacinamide and sebum-regulating acids. Dry skin requires ceramides, hyaluronic acid, and oils. Mature skin needs retinoids, peptides, and antioxidants. Sensitive skin needs panthenol, allantoin, and soothing ingredients.Good neckline cream with peptides and DMAE firms the skin in areas particularly susceptible to loss of firmness.
Active ingredients for different skin types:
- Oily skin – niacinamide, BHA (salicylic) acids, zinc, mattifying ingredients
- Dry skin – ceramides, hyaluronic acid, natural oils, shea butter
- Mature skin – retinoids, peptides, vitamins C and E, coenzyme Q10
- Sensitive skin – panthenol, allantoin, bisabolol, ceramides, fragrance-free
- Skin with discoloration – vitamin C, arbutin, azelaic acid, niacinamide
Which substances are suitable for dry skin and which for oily skin?
Dry skin needs ceramides, hyaluronic acid, natural oils, and shea butter. Oily skin needs niacinamide, AHA/BHA acids, zinc, and light humectants.
How does vitamin C work and who is it recommended for?
Vitamin C It's a powerful antioxidant that protects the skin from free radicals, brightens discolorations, supports collagen production, and improves skin tone. Recommended for all skin types, especially mature, discolored, and tired skin. Designed by us the best vitamin C serum combines vitamin C with vitamin E and ferulic acid, which enhances its effect and stability.
Benefits of using vitamin C:
- Antioxidant protection – neutralizes free radicals, protects against photoaging
- Lightening discolorations – inhibits melanin production, evens out skin tone
- Collagen stimulation – supports collagen synthesis, improves firmness
- Improved shine – brightens the complexion, gives it a healthy look
What forms of vitamin C are the most stable?
The most stable forms are Tetrahexyldecyl Ascorbate, Ascorbyl Glucoside and Ethyl Ascorbic Acid – they do not oxidize as quickly as pure L-ascorbic acid and are better tolerated by sensitive skin.
Which ingredients should be combined with vitamin C and which should be avoided?
Vitamin C combines well with vitamin E, ferulic acid and niacinamide. Avoid combining with retinoids and acids at one time – they can neutralize each other or irritate the skin.
Retinol – the gold standard in anti-aging care
Retinol is a vitamin A derivative that stimulates cell renewal, increases collagen production, reduces wrinkles, and improves skin texture. It's one of the most effective anti-aging ingredients with documented effects. Anti-wrinkle serum with retinyl retinoate – a stable form of retinol – works effectively, but more gently than pure retinol, also suitable for sensitive skin.
How to start retinol treatment and how to choose the concentration?
Start with a low concentration (0.1-0.31 TP3T) applied 2-3 times a week in the evening. Increase the frequency after 2-3 weeks. The skin needs time to adapt – Initial peeling and redness is normal.
How to minimize irritation during use?
Apply retinol to dry skin and wait 20 minutes after washing your face. Combine with a cream containing ceramides and panthenol. Always use SPF in the morning. If irritation is severe, reduce the frequency or concentration.
Niacinamide – a universal ingredient for all skin types
Niacinamide (vitamin B3) is a multifunctional ingredient – it strengthens the protective barrier, soothes inflammation, regulates sebum production, brightens discolorations, and reduces redness. It is suitable for all skin types, especially oily, sensitive, and discolored skin. Niacinamide Serum in a concentration of 10% it effectively supports the skin without causing irritation.
How does it work and in what concentration does it bring the best results?
You'll see the effects of niacinamide at a concentration of 2-5%, but the best results are seen at 5-10%. It strengthens the hydrolipid barrier, reduces sebum production, soothes inflammation, and evens out skin tone.
What can niacinamide be combined with and what should it not be used with?
Niacinamide combines well with most ingredients – ceramides, peptides, hyaluronic acid, vitamin C. Avoid combining it with pure L-ascorbic acid at a very low pH – they can neutralize each other.
Hyaluronic acid and moisturizing substances
Hyaluronic acid It's a humectant that binds water to the skin—one molecule can bind up to 1,000 water molecules. It intensely moisturizes, improves firmness, and smooths fine lines. Recommended for all skin types, especially dry and dehydrated skin.
What is the difference between low-molecular-weight and high-molecular-weight hyaluronic acid?
Low-molecular-weight (low molecular weight) penetrates deeper into the skin, moisturizing deeper layers. High-molecular-weight (high molecular weight) acts superficially, creating a protective layer. The best cosmetics combine both forms.
How to support the action of humectants in daily care?
Humectants (hyaluronic acid, glycerin) should be applied to damp skin and always followed by a cream or emollient to seal water in the epidermis. Humectants, on their own, can dry out the skin by drawing moisture from deeper layers.
AHA, BHA and PHA acids – how do they work and how to use them safely?
AHAs (glycolic, lactic, and mandelic acids) act on the skin's surface, exfoliating dead skin, brightening, and smoothing. BHAs (salicylic acid) dissolve in fat, penetrate pores, cleansing them, and regulating sebum. PHAs (lactobionic and gluconic acids) are more gentle, suitable for sensitive skin.
Action of acids:
- AHA (glycolic, lactic) – exfoliate, brighten, smooth wrinkles
- BHA (salicylic acid) – cleanse pores, regulate sebum, have antibacterial properties
- PHA (lactobionic) – gentle exfoliation, moisturizing, suitable for sensitive skin
How to choose the right type of acid for your skin type?
Dry and mature skin – AHA (lactic, almond). Oily and problematic skin – BHA (salicylic). Sensitive skin – PHA (lactobionic). Start with low concentrations and observe your reaction.
How often should you use chemical peels?
Use chemical peels 1-3 times a week, depending on the concentration and skin type. Start with once a week, gradually increasing the frequency. Always use SPF the next day.
Peptides – intelligent ingredients with a lifting effect
Peptides are short chains of amino acids that act as signals for the skin, stimulating collagen and elastin production, smoothing wrinkles, and improving skin firmness. Recommended for mature skin experiencing a loss of firmness.
Types of peptides and their effects:
- Signal peptides – stimulate the production of collagen and elastin
- Neuropeptides – relax facial muscles, reduce wrinkles
- Carrier peptides – transport minerals to the skin
- Inhibitory peptides – slow down the enzymatic processes leading to aging
How do peptides work and when should they be introduced into skincare?
Peptides stimulate fibroblasts to produce collagen and elastin, improving skin texture and smoothing wrinkles. They are recommended for preventative measures after the age of 30, or after the age of 40, when skin begins to lose firmness.
With what ingredients do peptides form effective duets?
Peptides combine well with niacinamide, ceramides, hyaluronic acid, and vitamins. Their effects are enhanced by antioxidants and moisturizing ingredients.
Ceramides and lipids – rebuilding the skin's protective barrier
Ceramides are natural skin lipids that form a protective barrier over the epidermis, preventing water loss and protecting against external factors. Recommended for dry, sensitive, atopic, and weakened skin.
How do ceramides work on the skin?
Ceramides rebuild the lipid layer of the epidermis, replenish the hydrolipid barrier, prevent water loss and strengthen the skin's immunity. Cream with ceramides Intensively moisturizes, regenerates and soothes irritations – ideal for skin requiring regeneration.
What are lipids and when should they be introduced into skincare?
Lipids (ceramides, cholesterol, fatty acids) form the skin's protective barrier. They are recommended when skin is dry, rough, or flaking, or after treatments that weaken the barrier (peels, retinoids).
Antioxidants in cosmetics – a shield against free radicals
Antioxidants neutralize free radicals that accelerate skin aging, destroy collagen, and lead to discoloration. The most important include vitamins C and E, coenzyme Q10, resveratrol, and niacinamide.
The most important antioxidants in care:
- Vitamin C – neutralizes free radicals, brightens, supports collagen
- Vitamin E – protects cell membranes, supports regeneration
- Coenzyme Q10 – supports energy production in cells, protects against aging
- Resveratrol – a strong plant antioxidant, slows down aging
- Niacinamide – protects against oxidative stress, strengthens the barrier
How do vitamins E, C and coenzyme Q10 work?
Vitamin E protects cell membranes from oxidation and supports regeneration. Vitamin C neutralizes free radicals, brightens, and supports collagen. Coenzyme Q10 supports energy production in cells and protects against aging.
What antioxidants are good for summer?
In summer, the most important ingredients are vitamins C, E and niacinamide – they strengthen SPF protection, neutralize free radicals created by UV radiation and support skin regeneration after sun exposure.
Soothing and anti-inflammatory ingredients
Soothing ingredients include panthenol, allantoin, bisabolol, and chamomile, aloe, and centella asiatica extracts, which reduce redness, soothe irritation, and support regeneration. Recommended for sensitive, reactive, and post-treatment skin. Moisturizing cleansing gel with panthenol and aloe vera, gently cleanses without irritating the skin.
How do allantoin, panthenol, bisabolol and plant extracts work?
Panthenol (provitamin B5) moisturizes, supports regeneration, soothes.
Allantoin has anti-inflammatory properties, accelerates healing.
Bisabolol (from chamomile) reduces redness, has a soothing effect.
Plant extracts (aloe, pennywort) soothe and protect.
How to use these substances for hyperreactive skin?
Use them every morning and evening – a serum with panthenol and niacinamide, and a cream with allantoin and ceramides. Avoid unnecessary ingredients that may irritate – fragrances, alcohol, and strong acids.
Ingredients with brightening and skin tone-evening properties
Brightening ingredients include vitamin C, arbutin, azelaic acid, kojic acid, and niacinamide – they inhibit melanin production, lighten discolorations, and even out skin tone. We recommend alpha-arbutin serum, which effectively reduces pigmentation spots and prevents the formation of new ones.
How do arbutin, azelaic acid and vitamin C work?
Arbutin inhibits the activity of tyrosinase, the enzyme responsible for melanin production. Azelaic acid brightens, has anti-inflammatory properties, and regulates sebum production. Vitamin C inhibits melanogenesis and lightens existing discolorations.
How to combine them in care to avoid irritation?
Use arbutin or azelaic acid in the morning and vitamin C in the evening. Avoid combining with strong acids at the same time. Always use SPF to protect your skin from exacerbating discoloration.
