Apply a small amount to face and neck after cleansing and toning. Please note the consistency of the product needs to be thicker than normal moisturizers without SPF to ensure that once applied to the skin the level of SPF is at the level stated on pack (in this case 25). The product can thicken over time, particularly with fluctuations of temperature. For best results, apply a serum beforehand to prep and hydrate the skin. Massage a small amount between the fingers for a few seconds to warm up and loosen the product then smooth over the skin and lightly massage in. For use all year round.
