Squalane + Copper Peptide Rapid Plumping Serum

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

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

A stable, saturated version of squalene, a lipid the skin already produces, now usually sourced from olives or sugarcane instead of shark liver. It is very well tolerated across skin types and helps reinforce the skin barrier.

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

A rheology modifier that thickens gels and serums while maintaining a lightweight, non-sticky feel. Provides suspension and stability in water-based formulas. Widely used and well tolerated.

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 natural osmolyte produced by halophilic bacteria. Used for hydration and protective stress response, ectoin is well tolerated with emerging evidence for skin barrier support and soothing. No safety concerns flagged in cosmetic applications.

A six-amino-acid peptide attached to palmitic acid that supports skin renewal and collagen production. Part of an established peptide family with consistent safety profiles across cosmetic applications.

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

Green tea extract is a well-studied topical antioxidant with a long history of use in serums and moisturizers, generally well tolerated at cosmetic concentrations. Panel safety reviews of Camellia sinensis-derived ingredients have not identified meaningful topical hazard.

An extract from neem tree leaves, valued for antioxidant and skin-conditioning benefits in formulations. Well tolerated overall, though isolated cases of contact sensitivity have been reported in the literature.

An extract from turmeric root valued for its antioxidant and skin-conditioning properties. It is well tolerated at cosmetic levels, though some sources note rare phototoxicity potential; formulation practices mitigate this.

An extract from the fruit of Coccinia indica, used in some skincare formulas for soothing and hydrating effects. Published safety data is limited, but the ingredient has not raised safety signals in cosmetic use.

An extract from neem tree flowers, used for its antioxidant and conditioning properties. While neem has traditional use in skincare, rare cases of contact sensitization have been noted in literature; most people tolerate it without issue.

An extract from holy basil (tulsi) leaves, used for antioxidant and skin-conditioning properties. It is graded safe at cosmetic concentrations and is generally well tolerated.

An extract from red algae valued for its humectant and antioxidant properties. It is well tolerated and commonly used in marine-based skincare formulations.

A cross-linked polymer used to thicken formulas and create lightweight gel textures. The large molecular weight prevents penetration into the skin and is not absorbed; well tolerated in cosmetics.

A natural, water-soluble polysaccharide gum harvested from the acacia tree, used to thicken and stabilize cosmetic formulations. It has a long history of safe use in personal care products. Very rare contact allergies or sensitivities have been reported in sensitized individuals.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

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.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.
