This Oil Liquid serum quickly absorbs into the skin, but it is not greasy or sticky. It rapidly hydrates and moisturises your skin to improve skin dryness and promote anti-ageing. The serum moisturises the skin from the inside out, so it optimises oil-moisture balance. It is effective on small acne or pimples. All skin types with acne problems can use this serum including sensitive, dry, and oily skin.
