Application

As part of your evening skincare routine, apply The Night Cream Treatment to the face and neck. To begin, use every two to three nights, gradually increasing to regular nightly use as tolerated.

As with retinol, you should always pair retinal with sunscreen during the day to protect your skin from increased sun sensitivity.

As the last step in your morning skincare routine, apply The Rejuvenating Moisturizing Primer Broad Spectrum SPF 30 to fingertips and gently sweep over the face and neck. Be sure to apply liberally and evenly to face 15 minutes before sun exposure and reapply as directed. Primes skin for makeup application or can be worn without makeup to even skin tone and protect skin from sun damage.
