Hyper-pigmentation refers to dark patches and spots on the skin. It can be caused as a result of skin injury or acne (also called post-inflammatory hyper-pigmentation), melasma (as a result of hormonal changes), age spots (due to aging pigmentation cells) or freckles (caused by exposure to the sun). Although theoretically, the sun is not the villain in all these hyper-pigmentation conditions, sunscreen is still very important to prevent and treat scars and spots as the sun has a major role to play. Wondering why sunscreen acts as a holy grail in your anti-marks skincare regime? Check out the details here:
ROLE OF SUN EXPOSURE IN HYPER-PIGMENTATION
- UV rays cause tanning of skin by inducing the production of melanin and its redistribution
- UV rays promote skin aging by affecting skin cells that include the cells that manufacture melanin.
Thus, exposure to sun tends to cause severe sun damage and aggravate post-inflammatory hyper-pigmentation, intensify melasma and multiply age spots at a faster rate. So, all kinds of hyper-pigmentation are influenced and affected by the sun, which is why, sunscreen is perhaps one of the best skin care ingredients to get rid of scars and spots.
