It is critical to determine your skin type. If you are confused about your skin type, here is a simple way to determine it:

Normal Skin: This skin type feels balanced. It is neither too oily nor too dry. Also, it is not excessively sensitive and does not react to anything applied to it.
Oily Skin: If your T-zone is shiny and greasy, you may have oily skin. Oily skin tends to have larger sebaceous glands that produce excess oil. It is also acne-prone.
Dry Skin: If your skin feels tight and itchy, especially after washing, you have dry skin. This type of skin feels patchy and itchy. It is also prone to premature aging.
Combination Skin: If your T-zone is oily and the cheeks and rest of the face are dry, you have combination skin.
Sensitive Skin: If your skin reacts to any product and gets irritated easily (especially after sun exposure), you have sensitive skin.
