What’s inside
Cellulose GumGenerally safe
A plant-based thickener derived from cellulose that creates smooth, gel-like textures in formulas. One of the most studied and best-tolerated thickeners in cosmetics, used in shampoos, face masks, and leave-on products for decades.
Full ingredient details →Hydrogenated Poly(C6-14 Olefin)Generally safe
A saturated hydrocarbon emollient that softens skin and gives products a smooth glide. Its saturated structure makes it stable and well tolerated. It is inert and carries a low sensitization risk at typical cosmetic use levels.
Full ingredient details →PolyisobuteneGenerally safe
A synthetic film-forming emollient that provides a protective, flexible layer on skin. Not absorbed and well tolerated with no documented safety issues in cosmetic use.
Full ingredient details →Salicylic AcidGenerally safe
A beta hydroxy acid used to smooth texture and clear pores. Safe at cosmetic levels; can be mildly irritating if overused.
Full ingredient details →Tea Tree OilWatch if sensitive
Tea tree oil is used for its antimicrobial reputation in blemish-focused products, but it is a genuine, well-documented contact sensitizer, and its allergy potential rises sharply once the oil has oxidized from air exposure. Fresh, well-preserved, low-concentration formulations are much lower risk than old or improperly stored oil.
