Moisturising helps replace lost moisture and prevent your skin from drying out. Not only does it help your skin retain moisture for longer, but it also keeps your skin looking visibly healthy and plump all day. By using a moisturiser containing SPF, you can help delay the development of fine lines and wrinkles caused by sun damage, and keep your skin looking younger for longer. Lastly, moisturising can also help soothe sensitive or irritable skin by giving it a boost of nourishment.
