Eucerin Aquaphor Repairing Ointment gives very dry and irritated skin the SOS care it needs. The soothing, transparent ointment forms a semi-occlusive protective barrier over the skin, allowing the skin to breathe and strengthen its natural barrier function. The glycerin in the formula is an effective moisturizer that attracts water and helps to keep it in the skin. It works alongside panthenol which helps to speed up regeneration and repair while also moisturizing the skin. Fragrance-free, in order to be well tolerated by sensitive skin, this product has been clinically and dermatologically proven to repair very dry, cracked and irritated skin, even on problem areas such as the knees and elbows, cracked knuckles and cuticles, and cracked heels.
