Skin types are generally divided into four main categories, each with its own specific needs: Oily skin: Characteristics: Shiny and prone to breakouts and acne due to excess oil production. Care: Use oil-controlling products and gentle cleansers. Dry skin: Characteristics: Flaky, rough and prone to dryness and cracking. Care: Use strong moisturizers and hydrating products. Combination skin: Characteristics: A combination of oily areas (usually in the T-zone of the face) and dry areas. Care: Use balancing products and care for different areas separately. Sensitive skin: Characteristics: Prone to irritation, redness and reactions to different products. Care: Use gentle, fragrance-free products and test new products before fully using them.
