Dermal Therapy's nourishing 10% Urea formula helps relieve dry, rough, problem skin and revitalizes your natural beauty. Urea is an important part of your skin's natural moisturizing system and is found in healthy young skin. Dermal therapy also includes alpha hydroxy acids which help displace old dry skin and reveal new skin which is more elastic. Dermal therapy contains silk protein to improve skin tone and luster, giving skin a silky, smooth, non greasy feel. It penetrates deeply into the skin to leave skin feeling silky smooth all over. Soothe dry skin. Non-greasy, non-toxic. Fragrance free, never animal tested. Since urea draws moisture deep into the skin, we recommend applying our product to slightly damp skin. Apply to skin 1-2 times daily or as needed. Discontinue use if rash or irritation occurs or worsen.
