Is salicylic acid the same as aspirin?

No. Aspirin is acetylsalicylic acid, a derivative of salicylic acid. Salicylic acid itself is too harsh for internal use as a common painkiller.

Can salicylic acid be used on sensitive skin?

It can be irritating. It's best to start with a low concentration and patch test, or consult a dermatologist.

Where does salicylic acid come from naturally?

It is found in the bark of willow trees (genus Salix), from which it gets its name, and in some fruits and vegetables.

What does 'keratolytic' mean in relation to salicylic acid?

It means it helps to break down and shed the outer layer of dead skin cells (keratin), promoting skin renewal.

My Flashcards

Definition

Meaning

A white crystalline organic acid (C₇H₆O₃) derived from willow bark or synthesized, widely used as a medicine (antipyretic, analgesic) and in skincare (for treating acne, psoriasis, and warts).

In chemistry: a beta hydroxy acid (BHA) with keratolytic properties, used in organic synthesis (e.g., to produce aspirin) and as a plant hormone. In cosmetics: a common exfoliating ingredient that penetrates pores to remove dead skin cells and reduce inflammation.

Linguistics

Semantic Notes

Primarily a chemical/medical term; rarely used in everyday conversation except when discussing skincare or medicine. Often preceded by a percentage (e.g., '2% salicylic acid') in product labels.

Dialectal Variation
