Skincare routines with:
SkinCeuticals Retinol 0.3 Refining Night Treatment

You can apply this product either during the day or at night, before your moisturizer or sunscreen. You can also apply it as a spot treatment only - as in directly on inflamed blemishes or in the area where you get clogged pores. We recommend that you use the product no more than once a week on larger areas of your face. More frequent use can result in skin irritation.
