Effaclar Purifying Cleanser is not an acne treatment. "Purifying" is a marketing word with no fixed meaning. This cleanser has no active ingredient — no salicylic acid and no benzoyl peroxide — so it does not treat acne. It is a basic cleanser with an acne-adjacent name.
That matters because it sits in an acne-branded line, which is how people end up believing it does more than it does. For actual acne treatment you need a product with a stated active.
Do not confuse it with Effaclar Medicated, which is a separate product with 2% salicylic acid. The names are close, and they are on the same shelf.

It cleans well and it foams nicely. For oily skin that wants a proper, thorough wash, it does that job, and people who use it generally like it.
Large 400 ml bottle.
The Effaclar line is well regarded for a reason, and this is a competent cleanser.
La Roche-Posay makes a better cleanser, for the same person, for five dollars less — and it is on the same shelf.
This (Effaclar Purifying, ~$25): contains a sulfate. Contains fragrance. No active. Toleriane Purifying (~$20): sulfate-free. Fragrance-free. No active.
Both are foaming cleansers aimed at oily skin. The cheaper one has the better formula. There is no version of this comparison where the Effaclar wins.
"Purifying" means nothing. There is no salicylic acid and no benzoyl peroxide in this. It is a basic cleanser with an acne-adjacent name, sitting in an acne-branded line — which is exactly how people end up believing it treats acne. It does not.
Do not confuse it with Effaclar Medicated — that one is a real 2% salicylic acid drug. Same line, same shelf, and the names are one word apart.
