Normal skin refers to well-balanced skin.  The scientific term for well-balanced skin is eudermic. The T-zone (forehead, chin and nose) may be a bit oily, but overall sebum and moisture is balanced and the skin is neither too oily nor too dry. The Skin displays a smooth texture and a rosy, clear surface, with fine pores. There are no visible blemishes, greasy patches or flaky areas. Sebum production, moisture content, keratinisation and desquamation are well-balanced. Normal skin is often found in young persons.
