Copper Peptide Professional Anti-Aging Serum

The base most products are built on. It carries the other ingredients and has no safety concern.

A light, low-odor glycol used as a solvent and humectant, extremely common in Korean toners and essences. It has a low reported irritation rate and is graded low concern in published assessments.

A form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

A small peptide bonded to copper that supports collagen remodeling and skin repair. Studied in cosmetics and dermatology for decades with a strong safety record at cosmetic-use levels.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

A lower molecular weight version of hyaluronic acid designed for better skin penetration. It has been extensively studied and shown to support skin hydration and barrier function with excellent tolerability in diverse formulations and skin types.

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A waxy sterol found naturally in skin and used in cosmetics as an emollient and emulsifier. It supports the skin barrier and is well tolerated across skin types.

A signal peptide designed to modulate muscle contraction and reduce the appearance of expression lines without systemic effects. Cosmetic formulations are well tolerated, with published assessments confirming safety at recommended concentrations.

A five-amino-acid peptide lipid that stimulates collagen and elastin synthesis. One of the most established peptides in cosmetics with decades of safe use and no reported sensitization issues.

A signal peptide attached to palmitic acid that activates collagen synthesis in skin cells. Well tolerated across skin types with no significant safety concerns in cosmetic use.

A peptide lipid that mimics collagen fragments and signals skin cells to increase collagen production while reducing inflammation. Established in anti-aging formulas with a consistent safety record.

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A salt derived from citric acid that buffers pH and prevents metal oxidation in formulas. Widely used in food and cosmetics, it is well tolerated at cosmetic concentrations.
