The cheap end of the cleanser shelf in Australia has quietly become the most credible. CeraVe, La Roche-Posay, Cetaphil — the formulas Australian dermatologists hand out at consult — sit at the Priceline and Chemist Warehouse price tier, and they outperform a lot of what gets shelf-talked at Mecca for triple the money.
The traps are upstream: sulphate-heavy foams that strip in week one, fragrance-loaded "sensitive" cleansers, and acid washes trying to do a serum's job for thirty seconds of contact. The heuristic when you're standing in the aisle: low to no foam, no fragrance, pH around 5.5.
