Ultra Light PDRN Pink Peptide Serum

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

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 lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

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

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

Sodium PCA is a natural component of skin's own moisturizing factor and is used in cosmetics as a humectant to help skin hold onto water. It has an extensive history of safe use with no meaningful irritation or sensitization signal.

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 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.

A naturally occurring nucleoside used in anti-aging formulas, often marketed for smoothing the look of fine lines. It has a low irritation profile and no established hazard at cosmetic use levels.

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

Sodium phytate is a plant-derived chelating agent used to bind trace metals and stabilize formulas, often as a preservative booster alongside other preservatives. Available safety reviews have not identified meaningful irritation or sensitization concerns at typical use levels.

Vitamin B12 used in cosmetics for its purported skin-conditioning and nutritional benefits. It is established as safe for topical use with no known hazards or sensitization concerns at concentrations typically used in skincare.

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 salt form of glycyrrhizic acid, a compound from licorice root prized for soothing irritated skin. It is well tolerated at cosmetic levels and has a long history of use in skincare formulations.

A basic amino acid naturally found in skin that draws moisture into the stratum corneum. It is well tolerated in cosmetics at typical concentrations and has been used safely in skincare formulations for decades.

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 lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

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 quaternized derivative of hyaluronic acid that combines hydration and film-forming benefits for enhanced moisturizing effects. It is documented in cosmetic use as well tolerated, though people sensitive to quaternary ammonium compounds may want to perform a patch test.

A synthetic peptide sequence derived from or mimicking Epidermal Growth Factor, designed to support skin renewal and healing. Cosmetic-grade formulations show no systemic absorption at recommended levels and are well tolerated in topical use.

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.

Collagen protein hydrolyzed into smaller peptide fragments used in skincare formulations. It is graded low concern, with very rare reports of sensitization. Those with severe shellfish allergies may want to verify sourcing.

A broken-down form of hyaluronic acid with smaller molecules intended to penetrate more deeply into the skin. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

A chemically modified form of hyaluronic acid that improves stability and penetration in skincare formulations. Clinical assessments show it hydrates skin effectively and is well tolerated across sensitive and normal skin types.

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 chemically cross-linked form of sodium hyaluronate designed to remain on the skin surface longer and provide sustained hydration. It functions as a humectant and is well tolerated, with the same safety profile as standard hyaluronic acid.

The potassium salt of hyaluronic acid, a naturally occurring molecule found in skin that binds moisture. It is graded with no known concerns in cosmetic assessments and is well tolerated across all skin types.

A synthetic iridescent pigment that creates a pearl-like shimmer. Generally well tolerated, though it can occasionally trigger irritation or heaviness in very sensitive or reactive skin. Patch test first if you have highly reactive skin.
