Sunlight is one of the major factors of having age spots or hyperpigmentation. This is in a way that prolonged exposure to the sun can aggravate the effects of age spots and pigmentation of the skin. When the skin has been exposed to too much ultraviolet rays, the results can be destructive. The right amount of UV rays help in the production of vitamin D. Too much ultraviolet rays causes skin damage and aging.
Applying sunscreen on skin may help prevent age spots and hyperpigmentation from getting worse. Sunscreens work by reflecting or absorbing the extra UV rays that the body doesn’t need. There are two types of ultraviolet rays that sunscreens inhibit, UVA and UVB. UVA can cause skin cancer to develop, on the other hand, UVB is the one that causes sunburn. The problem against sunscreens is its unbalanced protection, when UVA is disregarded and UVB is blocked, which can cause more skin damage. So, when it comes to applying sunscreens to avoid or lessen age spots and pigmentation, how are you going to choose the best type of sunscreen for you?
You have to know what type of skin you have first. There are 6 skin types according to Fitzpatrick (1975).
Type I (1-5 von Luschan scale) very light (celtic/Nordic)
Type II (6-10 von Luschan scale) light
Type III (11-15 von Luschan scale) light intermediate, dark skinned European
Type IV (16-21 von Luschan scale) dark intermediate, Mediterranean
Type V (22-28 von Luschan scale) dark/ brown type
Type IV (29-36 von Luschan scale) very dark/black
After that, list down all the things you’ll be doing that will require the use of sunscreen. Then, you can already buy a sunscreen that will fit your needs. But before buying check on its SPF or sun protection factor. The higher the SPF, the better the protection it gives to the user. In most countries, SPF levels extends up to SPF 50. Check the label for these ingredients to make sure that the sunscreen will provide effective protection for you: avobenzone, ecamsule or zinc oxide.
Anyway, sunblocks can be in gel, lotion or cream form. Sunscreens are not the only one which has SPF, some whitening lotions have them too but their main intention is different. But sunscreens are more effective than whitening lotion. aggregate these things up and you’re sure to get the best sunscreen for you.
However, it must be put in mind that sunscreens are not the medication for age spots and pigmentation. The only thing that sunscreens can give to people with age spots or hyperpigmentation is preventing it from getting worse. It is recommended to see a dermatologist when it comes to age spot removal.
