The skin is the largest organ of the body, and has many important functions. For instance, it prevents infectious agents from entering the body, shields internal structures from the sun’s harmful ultraviolet rays, protects the body from injury and regulates body temperature. It is also a major component of a person’s appearance. To remain healthy and looking its best, the skin requires regular care. 

Proper skin care involves washing the skin to remove dirt, sweat and oils, maintaining proper hydration (e.g., using a moisturizer and bath oils), and avoiding products that cause irritation (e.g., harsh soaps, perfumes). Skin care is required for good hygiene. It also contributes to the prevention of a number of skin conditions, including dryness, wrinkles, liver spots and skin cancer.

In addition to maintaining a daily skin care routine, good skin care also involves seeking medical care when necessary. People with skin problems such as rashes, itchiness (pruritus) or growths should seek medical treatment from a dermatologist soon after the condition develops. Dermatologists are physicians that specialize in diagnosing and treating conditions of the skin, mouth, hair, nails and external genitalia. 

Dermatologists can also recommend which products are best for different types of skin. What works well for dry skin may not be recommended for people with oily skin. People with certain conditions (e.g., acne, eczema) may also require certain types of soaps, moisturizers or other types of skin products.
