9 experts · Strong agreementWhat the gurus are saying
This watery toner earns praise for its peptide blend and poly glutamic acid, which gurus say hydrate without heaviness and work well for oily or combination skin. The texture is the standout: consistently described as incredibly lightweight and fast-absorbing, it layers seamlessly under treatments and leaves skin with a natural, non-greasy finish. One expert flagged misleading labeling on the Centella asiatica claim, noting the concentration is minimal, though they confirmed the product itself is soothing and safe for a compromised skin barrier; a few others caution that morning use with sunscreen may feel heavy on very oily skin, so evening application may suit those with oiliness best.
