The 10-second verdict: A safe, boring-in-a-good-way daily cleanser that suits almost everyone. Its low pH cleans without stripping, so skin feels clean but comfortable rather than tight. It is a light gel best for morning use or as a second cleanse at night, and it will not remove heavy makeup on its own.

What it is

A mild, low-pH gel cleanser with tea tree oil and botanical ingredients, formulated to respect the skin's natural acidity. It produces a light foam and rinses clean without a stripped, squeaky feeling. Suitable for most skin types, it is especially popular as a gentle morning cleanser or a second step after an oil cleanse.

What reviewers say

Long-time users love how gentle and non-drying it is, calling it a reliable everyday cleanser that never leaves skin tight. It is a frequent first recommendation for beginners. The main caveats: it is a light cleanser, so it will not fully remove sunscreen or makeup alone, and a few dislike the subtle tea tree scent.
