The desk verdict

A low-pH gel cleanser with betaine salicylate (a BHA) and tea tree oil, from £12.50 for 150ml. A gentle morning cleanse for oily and combination skin — but UK ingredient lists disagree on fragrance, so read your pack.

Skip this if you want a published BHA percentage, avoid tea tree oil, or need a formula confirmed as fragrance-free.
