How do I use it? Start with every other night for the first two weeks, using a small amount on targeted areas. If your skin feels sensitive, reduce use and apply a calming moisturizer. Avoid the eye area and wash hands after use. Can I use it in the morning? We recommend using this product at night only. Since the formula contains retinal, be sure to apply sunscreen the next morning to protect your skin. Will this product cause my skin to look yellow? Our formula contains a high concentration of retinal, a naturally yellow ingredient. This may give skin a slight yellow tint right after application, but it is temporary and washes off completely with cleansing. Why doesn’t the tube look completely full? For product stability, the tube may not look completely full. Don’t worry — it contains the exact amount stated, so you can use it with confidence. What if my skin feels sensitive after use? As this formula works effectively, you may experience mild sensitivity like redness or peeling. We suggest a quick patch test before first use, and simply adjust frequency to keep your skin comfortable.
