Limit initial use to three times per week; gradually increase frequency to every other night, then finally each evening as tolerated. Apply a pea-sized amount after cleansing and toning. Carefully avoid the lips, eyes (including eyelids) and corners of the eyes. Can be used on the perimeter of the orbital bone if desired. To minimize irritation, try combining with 2-3 drops of Resist Moisture Renewal Oil Booster.

Note: Some people may experience a delayed sensitized reaction to 1% retinol. Do not assume that if no reaction is seen after a few applications that you can apply this product more frequently. Pay close attention to how your skin responds and adjust usage accordingly.

If sensitization occurs (redness, flaking, tenderness, or drying of skin), reduce frequency of use or mix one pump of the Clinical 1% Retinol Treatment with your favorite Paula’s Choice serum or PM moisturizer. If sensitization persists, discontinue use. Protect skin daily with sunscreen rated SPF 30 or greater.
