If your skin reacts with redness, stinging, or sensitivity, stop using the serum immediately. Gently cleanse your face with lukewarm water and a mild, non-foaming cleanser. Apply a simple, fragrance-free moisturizer or a product with soothing ingredients like panthenol or ceramides to help support your skin barrier. Avoid any other active ingredients (like retinoids, vitamin C, or other acids), scrubs, and hot water for the next few days.
Once your skin has fully calmed down—which may take 3-7 days—reconsider your approach. You may have started too frequently or used too much product. When you reintroduce it, try applying it less often (e.g., once every 10 days), using a smaller amount, or applying your moisturizer first to act as a buffer. Always perform a patch test on a small area of your jawline before applying to your full face again.
This serum combines exfoliating acids, so introducing it gradually is key, especially if your skin is reactive. If sensitivity persists, it may not be the right product for your skin at this time.
