Depending on your skin type and your skin’s needs at a particular time, a hydrating serum may be used in place of moisturizer. Those with oily or blemish-prone skin may prefer to use our Hydrating B5 Gel in place of a traditional moisturizer. However, dry skin can benefit from using a hydrating serum in addition to moisturizer for extra skin nourishing moisture. When exercising or in a hot, humid climate, a hydrating serum may be a more comfortable moisturizer option for some. Additionally, individuals with sensitive skin will find hydrating serums, particularly those enriched with hyaluronic acid, to be immensely beneficial for soothing and calming their skin, while addressing issues like redness, dryness, and inflammation.
