Scaly skin can be a sign of a skin condition (i.e actinic keratosis, icthyosis vulgaris, psoriasis, seborrheic dermatitis, etc) which should be evaluated by a medical professional.
Scaly skin can sometimes occur with dry skin. Dermal Therapy urea based moisturizers can successfully hydrate very dry skin. Try Dermal Therapy Extra Strength Body Lotion or Dermal Therapy Alpha Hydroxy Lotion to experience how they actively restores moisture hydrating your skin to look and feel healthy and silky smooth.
