Cica Regen 92 Toner

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 plant extract long used in traditional wound care and now common in "cica" soothing products, valued for calming redness and supporting the skin barrier. It is generally well tolerated, with rare contact allergy reported.

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

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 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.

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.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

A plant extract used in Korean skincare for its soothing, antioxidant reputation. It is well tolerated with a low reported irritation rate; the soothing claims rest on limited but reasonable evidence.

An extract from the root of the Ulmus davidiana tree, used in some skincare formulas for soothing and conditioning effects. Published safety data is limited, but the ingredient has not raised signals in cosmetic use.

A purified triterpene from Centella asiatica (the "cica" plant) used in soothing and barrier-support products, especially Korean formulas. It is well tolerated with a low reported irritation rate; the strong repair and anti-aging claims around it are more marketing than settled evidence.

An antioxidant that helps protect a formula and condition skin. Well tolerated.
