This product contains strawberry juice, which provides fruit acids (AHAs) and antioxidants. While AHAs are valued in skincare for gently smoothing the skin's surface and helping to protect against external stress, they can be active ingredients. If you have very reactive skin or if your hands are currently chapped or broken, applying this product may cause a stinging sensation on the damaged areas. It is recommended to apply it cautiously at first to assess tolerance. For those with normal, dry, or seasonally dehydrated skin that is not actively broken, the balance of flaxseed oil, vitamin E, and caffeine is generally well-tolerated. Always avoid contact with the eye area, and if you experience persistent irritation, discontinue use. For external use only.
