Weak (W) Skin Types have skin that is vulnerable to various environmental triggers, and can feel constantly uncomfortable. Sometimes this skin type can progress to other skin problems easily because of its vulnerabilities. The aim here is to heal and protect the vulnerabilities in this skin type. Few products are suitable for this skin type, so don’t experiment with too many options even when you’re having a good day! Skin types can change with time and also with new triggers in the environment, so retake the quiz if new problems arise.
