멜라닌 색소를 뭉치게해서 색소침착이되는군요
Using sunscreen to protect your skin from the hot sun feels like a necessity these days, doesn't it? But I'm sure you all know that you need to know how to use sunscreen properly, right? Many people tend to think that when sunlight hits their skin, the UV rays directly darken it. However, in reality, it causes existing melanin pigments in the skin to clump together, leading to pigmentation.
Therefore, to prevent hyperpigmentation, it is essential to apply sunscreen 30 minutes before going outside! This allows the sunscreen to be sufficiently absorbed into the dermis deep within the skin and perform its proper function of protecting the skin by reflecting sunlight. It is best to apply an amount of sunscreen roughly the size of your index finger joint, spread it out, and then pat it in. Please remember that if you apply less than a finger joint, your skin will not be able to reflect sunlight sufficiently.
