Lanolin
The AI Verdict
Lanolin is a waxy substance secreted by the sebaceous glands of wool-bearing animals. While incredibly moisturizing for dry, cracked skin, it is highly comedogenic and an absolute nightmare for acne-prone skin. It forms a thick occlusive barrier that traps dead skin, bacteria, and sebum, directly leading to severe breakouts and closed comedones.
Chemical Profile & Risk Factors
A refined derivative of lanolin with a high comedogenic rating of 4 out of 5. It penetrates pores deeply and causes severe congestion.
Chemically altered to be less sticky, but this makes it penetrate and clog pores even more efficiently than pure lanolin, earning a 4-5 comedogenic rating.
Can trigger contact dermatitis and allergic reactions in individuals sensitive to wool alcohols, compounding acne inflammation.
