A wrinkle is a fold, ridge, line or crease in the skin. Our skin gets wrinkled with advanced age, prolonged illness, sun damage, smoking, body dehydration, skin dryness and habitual facial expressions. Genetics, ethnicity and exposure to the environment are factors that affect severity of this condition. Using a broad spectrum sunscreen, a moisturizer for effective hydration and having a regular skincare routine in place is primary to delay fine lines. Severe wrinkles can be treated with fillers and resurfacing treatments.
