Wearing sunscreen is one of the easiest and most effective ways to protect your skin from harmful ultraviolet (UV) rays. Sunscreen can be rewarding in numerous ways and should be applied every day for better results. But have you ever tried the double-layer sunscreen technique? According to dermatologist Dr Aparajita Lamba, the double-layer technique ensures that you “apply the sunscreen correctly, in a layered way”. “In this technique, whatever the amount of sunscreen, you are supposed to apply half as one layer, wait for five minutes, and then go for the second layer. You don’t necessarily need to apply more sunscreen. All you need to do is layer it,” said Dr Lamba, adding that it is a tan-proof technique. Does it work? Dr Rinky Kapoor, consultant dermatologist, cosmetic dermatologist, and dermato-surgeon, The Esthetic Clinics shed light on the technique.She said that abiding by the technique would mean that the quantity of sunscreen that was supposed to be applied in one go, “will now be divided and used in two stages”. “Apply the first layer generously, covering all the essential areas that are directly exposed to UV rays such as the face, neck, and also behind the neck, hands, legs, and feet. Apply the second layer of sunscreen once the first layer is absorbed, which is mostly after 10 to 15 minutes,” explained Dr Kapoor.She said that this double-layer application “can provide maximum coverage to your skin ensuring no spots are missed and also provides a thicker barrier against harmful UV rays”.
