Youth Serum

An acetylated derivative of the amino acid tyrosine, used in cosmetic actives distinct from plain tyrosine.

A nucleotide that serves as the primary energy carrier in cells, included in some skincare actives to support cellular energy metabolism claims.

A fat-soluble ester of ascorbic acid (vitamin C) and palmitic acid used as an antioxidant in cosmetics to protect against oxidative damage and extend formula shelf life.

A centella-derived triterpene active in the 'madecassic/asiatic' family, valued for soothing and barrier-supporting effects.

A purified triterpene saponin from centella (Centella Asiatica). One of the key 'cica' actives, used for its calming and skin-repair properties.

An antioxidant used to reduce the look of puffiness and dark circles.

Ergothioneine (L-ergothioneine, EGT) is a naturally occurring amino thione acid originally found in ergot fungi. It is synthesized in nature only by fungi and certain bacteria, but is avidly accumulated by human cells (especially tissues under oxidative stress) via the highly specific OCTN1 transporter. This unique cellular uptake mechanism distinguishes ergothioneine from most antioxidants — it is actively concentrated inside cells rather than merely acting on the surface. In cosmetics it functions as a premium anti-aging antioxidant active used in high-performance vitamin C ampoules and anti-aging serums.

A gold-standard humectant that draws water into the skin.

An extract from Haberlea rhodopensis, the 'resurrection plant', rich in myconoside and phenolic antioxidants that support collagen synthesis and skin elasticity.

A protein derived from enzymatic hydrolysis of milk casein into smaller peptides, used as a skin-conditioning and film-forming humectant.

Enzymatically hydrolyzed soybean protein peptides used as a humectant and skin conditioner that helps retain moisture and smooth the skin surface.

A broad INCI category covering protein hydrolysates from plant sources (soy, wheat, rice, corn, pea, etc.) broken down into amino acids and peptide chains by acid, alkali, or enzymatic hydrolysis. Amino acids are NMF components that support the skin's natural moisture-retention capacity. Frequently used in formulas where specific protein sources are not disclosed or where a blend is intentional.

A mixture of peptides and amino acids obtained by hydrolysis of wheat protein, used as a humectant and film-forming skin-conditioning agent.

A mixture of peptides and amino acids obtained by hydrolysis of wheat protein, used as a humectant and film-forming skin-conditioning agent.

A triterpenoid component of Centella asiatica known for soothing and barrier-supporting effects.

A generic INCI listing for a mixture of phospholipids (phosphatidylcholine, phosphatidylethanolamine, and related compounds) that are structural components of cell membranes, used to reinforce the skin barrier and aid active delivery.

A cyclic amino acid that functions as a humectant and forms part of the skin's natural moisturizing factor.

A marine-bacteria ferment (exopolysaccharide) that hydrates and soothes sensitive skin.

The mildest common vitamin A ester. It converts slowly to retinol/retinoic acid in skin, giving low-irritation anti-aging benefits — weaker but gentler than retinol.

A plant-derived carbohydrate complex that binds to skin for long-lasting, anchored hydration.

The stable ester form of vitamin E that converts to active tocopherol in skin; a common, shelf-stable antioxidant.

A short synthetic tripeptide that mimics a collagen fragment, used in anti-aging formulations to support collagen production and skin resilience.

A synthetic tripeptide incorporating citrulline; targets the extracellular matrix to improve skin firmness and elasticity by supporting fibulin-7-mediated collagen organization.

A complex mixture of proteins, peptides, amino acids, vitamins, and polysaccharides derived from Saccharomyces cerevisiae yeast, used as a skin-conditioning and protecting active.
