Skin types are generally categorized as normal, oily, dry, sensitive, or combination. Skin type can change over time and be influenced by hormones, medications, and diet. To determine your skin type, wash your face gently and leave it product-free for several hours, then observe its characteristics in different areas. Paying attention to your skin's appearance, feel, and reactions to products is crucial for developing an effective skincare routine.

Uneven skin tone, often caused by uneven pigment distribution, sun exposure, or hormonal changes, can be addressed with serums, creams, or moisturizers containing ingredients like vitamin C. Regular exfoliation can also help by removing dead skin cells.
