The PHA 5% Exfoliating Lip Serum is an innovative chemical peel that combines gentle active ingredients. Its formulation contains gluconolactone and alpha-hydroxy acids that provide effective exfoliation without compromising the skin barrier. With over 50% glycerin, the serum delivers intense hydration and enhances the softness of the lips, while ectoin helps maintain long-lasting moisture balance. This serum gently promotes skin renewal, visibly improving the appearance and texture of the lips, giving them a bright and healthy look. It can also be used under the lip balm for deep care overnight.
