Moisturiser can be applied at anytime though they work best after a bath when the skin is a little receptive. Have a bath, dry pat the skin and then apply moisturiser.​A good skin care regimen comprises 4 steps - cleansing, toning, moisturizing and sun block. Consider usage of a moisturizing cream like Venusian, Cetaphil cream or Aveeno skin cream. Based on your skin type, a dermatologist will recommend you appropriate products. Hope it helps.
