Anti-aging cosmetic ingredients

Water-soluble antioxidant that inhibits tyrosinase and stimulates collagen synthesis. Unstable upon oxidation, requiring careful storage.

Synthetic tripeptide modeled on a peptide from the temple viper venom. Marketing compares it to botox; actual clinical studies are scarce.

Third-generation synthetic retinoid. Photostable, less irritating than tretinoin. Available OTC at 0.1% concentration (Differin).

Natural nucleoside acting via skin adenosine receptors. Stimulates collagen synthesis and improves skin firmness.

Triterpenic saponin from Centella asiatica. Stimulates type I collagen synthesis and accelerates healing. Part of TECA (Titrated Extract of Centella Asiatica) used in scar gels.

Amphiphilic antioxidant soluble in both water and oils. Skincare promises «universal anti-aging protection»; clinical studies more often show a moderate effect.

Stable glycoside of ascorbic acid. Converted to vitamin C by alpha-glucosidase after skin penetration.

Oil-soluble vitamin C derivative. More stable than L-ascorbic acid with better penetration through the lipid barrier. Converts to ascorbic acid inside the skin.

Red carotenoid from the microalga Haematococcus pluvialis. A strong antioxidant, but topical formulas run into its low penetration ability.

Updated version of the Argireline peptide. Marketing promises a reduction of expression wrinkles «like botox», but clinical effects are much more modest.

Peptide with potential stimulation of thymus-driven epidermal renewal. Features in formulas against tone loss and tired skin.

Synthetic peptide, a SNAP-25 fragment. Marketed as 'botox in a jar' – suppresses neurotransmitter release at the neuromuscular junction. In reality, the effect is orders of magnitude weaker than botulinum toxin.

Plant meroterpene from Psoralea corylifolia seeds. Marketed as a "plant-based retinol alternative" – activates the same receptor pathways without retinoid irritation.

Fragmented hyaluronic acid with a mass <50 kDa. Penetrates the epidermis better than the high-molecular form, but at high concentrations may trigger a pro-inflammatory response.

Retinoic acid ester known under the brand Granactive Retinoid. Irritates the skin less than retinol but also has a noticeably smaller clinical base.

Alpha-hydroxy acid (AHA) with the smallest molecular weight in the group. Accelerates desquamation, evens skin tone and texture.

Tripeptide of glutamate, cysteine and glycine – key intracellular antioxidant. In cosmetics it promises skin brightening through tyrosinase inhibition and a switch in melanin synthesis.

Polyhydroxy acid (PHA) – a gentle AHA alternative. Its large molecular size slows penetration, reducing irritation. Also hydrates through hygroscopicity.

Synthetic analog of ubiquinone (CoQ10) with higher stability. Works as an antioxidant and mitochondrial protector and has been studied in dermatology since the 2000s.

Dipeptide of beta-alanine and histidine, a natural antioxidant. Binds glycation end-products and protects skin proteins from oxidation.

Alkaloid from coffee beans and tea leaves. Stimulates microcirculation, constricts vessels and delivers antioxidant protection.

Polyhydroxy acid (PHA) with antioxidant properties. Chelates iron ions, preventing oxidative stress. Its large molecule provides gentle exfoliation without irritation.

Bifidobacteria probiotic lysate, the key active in Estee Lauder Advanced Night Repair serum. Works on skin barrier recovery.

The primary triterpenic glycoside from Centella asiatica. Suppresses inflammation and stimulates type I collagen synthesis. More standardized than raw centella extract.

Light fatty oil with a high share of linoleic acid. Suits oily and combination skin – absorbs faster than olive or avocado.

Rich orange oil with carotenoids, vitamin E and omega-7. Restores dry skin and at higher doses can tint skin and fabrics.

Synthetic peptide mimicking a type I collagen fragment. Activates synthesis of collagen, fibronectin, and hyaluronic acid via dermal cell signaling pathways.

Tripeptide-copper complex that stimulates synthesis of collagen, elastin, and glycosaminoglycans. Accelerates wound healing and exerts anti-inflammatory effects.

AHA with a large molecule (bigger than glycolic acid). Penetrates skin more slowly, making it gentler. Suitable for darker phototypes where glycolic acid more often triggers post-inflammatory hyperpigmentation.

AHA with dual action: acid exfoliation and moisturization via hygroscopicity. Gentler than glycolic acid.

Synthetic lipopeptide that suppresses interleukin-6 (IL-6), a pro-inflammatory cytokine. Part of the Matrixyl 3000 complex alongside palmitoyl tripeptide-1.

Lipopeptide mimicking a collagen fragment. Stimulates fibroblasts to produce collagen and hyaluronic acid. Often combined with palmitoyl tetrapeptide-7 (Matrixyl 3000).

Salmon DNA fragments with molecular weight 50–1500 kDa. Activate purinergic receptors, stimulating angiogenesis and regeneration. Topical application is limited by molecular size.

Natural polysaccharide produced by fermentation of Aureobasidium pullulans fungus. Forms a thin skin film and gives a temporary lifting effect.

Polyphenol from grape skin and berries. Antioxidant that activates sirtuins. Topical bioavailability is limited by molecular instability.

Intermediate vitamin A form between retinol and retinoic acid. More potent than retinol but gentler than tretinoin.

Weak retinoid form: a retinol ester with acetic acid. Low bioavailability on skin, a weaker effect than retinol and retinal.

Ester of retinol and palmitic acid – the most stable but also weakest form of vitamin A in cosmetics. Requires two conversion steps to reach active retinoic acid.

A vitamin A derivative converted by skin into retinoic acid. One of the best-studied topical ingredients with proven anti-aging efficacy.

Third-generation topical retinoid with strong antiproliferative action. Doctors prescribe it for psoriasis, acne and photoaging.

Retinoic acid – the most active topical form of vitamin A. A prescription drug and the gold standard for topical anti-aging and acne treatment.

Fourth-generation retinoid with selective action on RAR-gamma receptors. Galderma markets it as Aklief for facial and truncal acne.

Peptide from the Matrixyl 3000 anti-age complex. Suppresses procollagenase activity and supports collagen synthesis.

Coenzyme involved in mitochondrial respiration. Its skin levels decline with age. An antioxidant protecting cell membranes from lipid peroxidation.

Plant-derived hydroxycinnamic acid. Standalone antioxidant that enhances and stabilizes vitamins C and E in cosmetic formulas.

Tropical plant whose extract contains asiaticoside, madecassoside, and brahmoside. Stimulates collagen synthesis and reduces inflammation.

Yellow gentian root extract with bitter glycosides and xanthones. Tones the skin, delivers antioxidant action and often features in alpine formulas for mature skin.

Ginseng root extract with ginsenosides. In Asian formulas it serves as an adaptogen and a component of «energizing» serums.

Source of polyphenols, the main one being EGCG (epigallocatechin-3-gallate). An antioxidant, anti-inflammatory, and photoprotective agent.

Extract from a cell culture of a rare apple variety. Marketing sells it as «stem cells for the skin», yet human clinical base is nearly absent.

Brown algae extract rich in alginates, iodine and minerals. In cosmetics it works as a humectant and conditioning ingredient.

Rice bran extract with gamma-oryzanol, tocopherols and ferulic acid. A traditional component of Japanese and Korean cosmetics for glow.

53-amino-acid peptide that stimulates keratinocyte and fibroblast proliferation. Used in post-procedure care and anti-aging products.

Stable vitamin C derivative with an ethyl group. Irritates the skin less than pure L-ascorbic acid and retains activity in neutral-pH formulas.
