What vitamins are beneficial for thin skin?

Vitamin A and retinol are beneficial for treating thin skin when used under the supervision of a doctor, says Mayo Clinic. People with thin, fragile skin can prevent injuries by wearing multiple clothing layers, avoiding lengthy exposure to the sun and applying a high-quality moisturizer.

Thin, easily torn skin is particularly a common condition among older people, says Mayo Clinic. Genetic factors can play a role in the development of thin skin. Synthetic forms of vitamin A, retinol and retinoids are also prescribed to treat acne and warts as well as thin skin, according to the University of Maryland Medical Center.
