If you do not need a moisturizer, its a wasted step. Moisturizer has no benefit except to hydrate your skin. It will not thicken collagen, delay wrinkles, prevent loss of subcutaneous elasticity. It will just keep the dead layer of your epidermis-the stratum corneum (glassy layer) moist.

If you are using a sunscreen prone to degredation like avobenzene, octinoxalate, homosalate,octisalate, etc...you must reapply this product every 2 hours. Barrier suncreens like zinc, and possibley titanium do not degrade with light exposure. Degradation of your sunscreen means free radicals form-and free radicals will age you as fast as UV/UVB/UVA rays. Not to mention once the sunscreen is over three hours on year skin its useless.
