It is important to follow the specific instructions provided for an antioxidant serum product, as they may vary depending on the product and its ingredients. Here are some general guidelines for when and how to use antioxidant serums for face: - When to use: Antioxidant serums can be used in the morning and/or evening, depending on your skincare routine and the specific products being used. Similar to most face serums, they are applied to the skin after cleansing and toning, but before moisturising. For day use, we recommend antioxidant serums with vitamin C to protect skin from environmental damage and sun damage. For night use, the Resveratrol B E Night Serum contains resveratrol to help restore balance and strength to the skin during sleep. - How to use: Apply a small amount of the serum to your clean, dry face, avoiding the eye area. Gently massage the serum into your skin using circular motions until it is fully absorbed. Follow up with your face moisturiser and/or sunscreen as needed. If you are using multiple serums or treatments, apply the antioxidant serum first to ensure it is able to fully penetrate the skin and provide maximum protection. When using an antioxidant serum in the morning, always follow with a broad spectrum sunscreen (at least SPF 30) to protect your skin from further sun damage. Important note: Always patch test any new product on a small area of your skin before applying it to your entire face to avoid any potential allergic reactions, or consult with a dermatologist or skincare professional for any concerns.
