Lip product with seaweed extract for lip darkening
Part of Skin clinical trials.
This study tests a new lip product made with a seaweed extract (Caulerpa lentillifera) to see if it can reduce darkening of the lips. If you have lip hyperpigmentation and want to try a natural option, this may be a good fit.
