Sun damage can cause premature aging such as pigmentation and lines. Research shows 90 percent of wrinkles are caused by the sun's UVA light and sun damage is the #1 cause of premature aging in women and men.
Why are UVA rays so bad? Even at low-level exposures, UVA light breaks down collagen, which causes wrinkles. Even worse, scientists have found that UVA is the main culprit for many melanomas because it reaches deep into the underlying support structure of the skin. It causes pigmentation spots such as freckles.
Isn't it scary to look like 35 when in fact you are only 25?
Let's see what goes in a bottle of sunblock/ sunscreen.
What is SPF?
SPF- sun protection factor
The higher the SPF, the more protection a sunscreen offers against UV-B (the ultraviolet radiation that causes sunburn).
What does PA+++ mean?
Apart from SPF, some sunscreen labels also list a "PA" ranking. While SPF indicates how much the product can protect you from UVB, PA on the other hand refers to the amount of protection the sunscreen offers against UVA rays, Dr Nussra notes. You will see PA+, PA++ and PA+++. More plus symbols mean more protection from UVA.
UVA exposure also is known to lead to signs of premature aging of the skin such as wrinkling and age spots. The UVB rays are the sun's burning rays (which are blocked by window glass) and are the primary cause of sunburn. Excessive exposure to both forms of UV rays can lead to the development of skin cancer. So prevention is better than cure. Do apply sunblock always.
