Everyone knows the importance of sunscreen – to avoid sunburn, skin cancers, etc. But there’s actually a lot more to it than most of us think. Did you know that sun damage is the biggest cause of premature aging? This, amongst many other reasons, is why applying SPF every day should be the foundation of any skincare routine.
What is really happening in the skin when we are exposed to the sun?
The sun gives off rays of light known as ultraviolet (UV) rays. There are two types of UV rays – UVA and UVB – both of which damage the skin in different ways. UVB rays are responsible for burnt, red and tender skin, whereas UVA rays penetrate deeper into the layers of the skin causing fine lines, wrinkles, discolouration, thinner and more fragile skin.
A few consequences of prolonged, unprotected sun exposure include:
- Depleted levels of essential fatty acids, leaving skin dry, flaky, and rough
- Slowed rate of skin cell renewal, causing a buildup of old dead skin cells resulting in
dull, congested skin
- Destroyed collagen and elastin, leading a loss of elasticity, prone to further damage
and increased wrinkles and sagging.
By simply adding sunscreen into your daily morning routine, you are able to combat and prevent this damage.
