Wrinkles are formed due to the ageing of skin.
There are three main factors that contribute towards skin ageing:
A] Free Radicals and Ageing
‘Free radicals’ are unstable molecules that are generated in our body to help create energy. The body has its own natural antioxidants that control these free radicals and stabilize them.
But, when our body’s supply of antioxidants can’t keep up with the amount of free radicals being formed, these free radicals begin damaging everything in their path, including skin cells. This affects the skin cells’ functioning, which leads to premature ageing and wrinkles.1
Smoking, the sun’s rays, a bad diet and environmental factors like pollution all contribute towards free radical damage.
B] Collagen and Ageing
Our skin cells have this ability to secrete proteins into their surroundings, which create structures to hold the skin together. A strong structure means a smooth, firm surface.
75% of this is made up of a protein called collagen.2 The production of this protein begins to slow down as we age, which affects the skin’s structure, making it less firm than before.3
A loose structure means uneven, wrinkled skin.
C] Sun Damage and Ageing
There are two types of the sun’s UV rays that affect our skin: UV-A and UV-B.4
UV-B rays only reach the surface of our skin. These cause sunburn and skin cancer, but are mostly blocked out by the SPF (skin protection factor) in our sunscreens.
The UV-A rays, on the other hand, penetrate deeper into the skin. They are able to reach into the middle layer, the dermis.
Free radicals and the body’s reaction to sunburn can damage the skin network that contains collagen and other proteins, which, over time, leads to wrinkles.
So, how can we protect our skin from all of these factors?
1. Externally –
Applying sunscreen is a pretty obvious solution, but, specifically, applying ‘broad spectrum’ sunscreens is needed in order to get protection from both the UV-A and UV-B rays of the sun. Make sure you reapply your sunscreen every 2-3 hours.5
You can also wear sunglasses, which will stop you from squinting in the sun and ultimately developing crow’s feet by damaging the skin structures around the corner of your eyes.
2. Through Nutrition –
Nutrition plays a huge role in maintaining youthful skin!
Eating foods rich in antioxidants will help fight against free radical damage. Get plenty of these in your diet! Lycopene, which makes tomatoes red, is especially great for skin protection since it even protects the skin from the sun’s damaging rays.6
For those who find it difficult to consume a lot of fruits and vegetables on a daily basis, Nutrova Collagen + Antioxidants has been designed to (a) provide a source of collagen that can be absorbed by the body, thus strengthening the skin’s structure and (b) fight free radical damage through natural antioxidants like lycopene.
