Ratings

Overall Rating

Fair

Comedogenic Risk

High

High likelihood of clogging pores, generally avoided in acne-prone routines.

Is Isopropyl Myristate a Good Ingredient?

Rated Fair because it delivers excellent slip and lightweight emollience, but its high comedogenic tendency makes it a breakout risk for acne-prone skin, and that risk is enough to hold the rating back.

Skin Benefits

Softens rough, dry areas and leaves a lightweight, silky afterfeel. Some acne-prone users may notice increased breakouts.

Uses in Skincare & Cosmetics

Common in lightweight lotions, facial oils, and makeup removers to boost slip. Also used in foundations and primers to improve spread during application.

Safety

Generally tolerated on intact skin, but it carries a significant comedogenic risk and may worsen clogged pores or folliculitis in breakout-prone areas. Irritation is uncommon but can occur, especially under heavy occlusion.
