Sebiaclear Active

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

Gluconolactone is a polyhydroxy acid that exfoliates gently while also acting as a humectant and mild antioxidant, and it is generally recommended for sensitive or barrier-compromised skin over smaller AHAs. A full cosmetic panel review found it safe as used, though some users still report mild stinging or redness at higher concentrations.

A lightweight, volatile silicone that gives serums and primers their silky slip and quick-evaporating finish. Human safety data are reassuring; the EU restriction on this ingredient in rinse-off products is about environmental persistence in waterways, not skin safety.

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.

An acrylic crosspolymer used to thicken and stabilize cosmetic products. Established use in cosmetics indicates minimal skin irritation potential at typical formulation levels.

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

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

A synthetic polymer used to thicken and stabilize water-based formulas like gels and serums. It provides texture and suspension of particles without interfering with skin feel. Well established in cosmetics.

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 beta hydroxy acid used to smooth texture and clear pores. Safe at cosmetic levels; can be mildly irritating if overused.

A naturally derived humectant made from fermented plant sugars that draws water into the skin. It is well tolerated in cosmetics and is used to support hydration and skin softness.

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

Dimethiconol is a silicone emollient closely related to dimethicone, used to add slip and a smooth finish to creams and serums. It shares dimethicone's long-standing safety record and is considered non-sensitizing and non-comedogenic in typical use.

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

A PEG-based emulsifier that blends oils and water in formulas. It is a workhorse ingredient in stable emulsions and is approved for cosmetic use. Well tolerated.

A synthetic surfactant widely used to emulsify oils and water in cosmetics. It is well tolerated and has been used safely in cosmetic formulations for decades.

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.

An emulsifier made from sorbitol and isostearic acid, used to stabilize oil-in-water formulas. The Cosmetic Ingredient Review panel assessed it as safe for cosmetic use at typical concentrations.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.
