Skin can be classified using various criteria, with one of the most well-known being Fitzpatrick’s classification from 1975. This system categorizes skin based on its color and response to sun exposure, helping to determine the appropriate sun protection factor (SPF) and assess risks such as skin cancer.
From a cosmetic perspective, skin is primarily classified based on factors that influence its balance, including sebaceous secretion, hydration levels, and sensitivity. Each skin type possesses unique characteristics and requires tailored care. While genetics play a key role in determining skin type, it can also be influenced by environmental factors, lifestyle, and aging, leading to changes over time.
Based on these criteria, healthy skin can generally be divided into five types:
- Normal
- Dry
- Oily
- Combination (a mix of oily and dry areas)
- Sensitive
