Can sunscreen be used as a moisturizer?

Wash your face 4 times a day with the prescribed cleanser – This I do not follow for fear of drying out my skin; I only cleanse twice a day. I do not know what is in his prescribed cleanser, so I’m unable to comment on his 4 times a day regime. I personally think that cleansing twice a day is perfectly reasonable, and I do that myself too. I’d rather suspect that the cleanser has some type of a moisturizing/sunblock component in it too – which is why he’s told you to stay off moisturizers and sunblock otherwise completely.

Dryness of the hands and feet since birth is uncommon. This may be due to an underlying condition like ichthyosis where there is a defect in the skin's natural moisturiser production, resulting in skin dryness and peeling. Hand and feet eczema and other conditions like keratolysis exfoliativa and palmoplantar keratoderma can also cause dry and scaly hands and feet. The general advice is to minimize contact with soap and detergents and irritants which can aggravate the hand dryness. Frequent application of moisturizers to improve the skin barrier is important.
