COSRX Low pH Good Morning Gel Cleanser
Updated Nov 8, 2026 · Top Face cleansers
Best for Oily skin that wants a low-pH gel and is not reactive to tea tree or salicylic-type ingredients.
A low-pH gel wash with betaine salicylate and tea tree oil, sold as a 5.07 fl oz bottle. COSRX says the pH sits near the skin's own and that a small irritation test on 34 people found no reaction at 24, 48, and 72 hours. That is the brand's test, and it is short. Tea tree and a salicylic-type ingredient are the reason sensitive and eczema-prone skin often stings on this gel. Dermatologist surveys that rank CeraVe, Cetaphil, and Vanicream do not place this cleanser. Use it if you are oily and the cream washes feel like they did nothing. Skip it on a broken barrier.
