Isn't using sunscreen now a necessity, not an option, to protect your skin from the hot sun? It is important to know how to use sunscreen properly! Many people mistakenly believe that when sunlight hits the skin, the UV rays directly cause it to darken. 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!
