You don’t decide your skin type – your skin type is with you since the day you were born, but remember this is not a scientific skin classification. When white skin is normal, there are barely any visible pores and a radiant, pinkish complexion. This means your skin has enough water and lipids, with a good balance and a moderate sensitivity level. You can achieve normal skin by having an ideal balance between the rate of sebum production and cellular exchange.
NORMAL, COMBINATION SKIN
With normal, combination skin, your pores are enlarged and tend to have blackheads, and your skin is shiny in the T-zone. It's either overly dry or overly oily, with occasional roughness on your cheeks. The oiliness and dryness can change depending on the time of year. Your skin is usually drier when the weather is cold, but even if you have oily skin it can become rough and irritated in the winter. Combination skin is caused by an imbalance in the production and distribution of lipids due to hormonal and genetic factors.
Dry skin is caused by genetic or hormonal aging, as well as external factors such as wind and UV radiation. Dry skin has almost invisible pores and a dull, rough complexion with red patches. But it can be normal at times, and fine and delicate at other times. Your skin can be temporarily dry from sunburn, burns, cold temperatures, abrasions, and certain medications. While it repairs itself, you'll experience, dryness, flaking, and sometimes itchiness. Some people may suffer from a dry-skin condition, which runs in families, where their skin doesn't itch, but the disease makes their skin flake and sometimes crack.
Sensitive can be inherited or acquired. It appears blotchy, and may feel burning or itchy. Sensitive skin responds to various triggers like allergens, preservatives, fragrances, or simply a change in temperature or season.
Oily skin has dilated pores, blackheads and pimples. Touching oily skin may sometimes leave a residue of oil on the fingertips. This type of skin appears shiny, thick, or slightly waxy. Oily skin is caused by hyperactivity of the sebaceous glands that produce more oil than you need. It can be due to puberty or other hormonal imbalances, stress, antibiotics, and exposure to heat or excessive humidity. The oiliness of your skin can change from day to day, depending on the weather and season.
