Skin needs different types of protection.
Daylight and sunshine contain UVA which ages, causes loss of collagen and pigmentation irregularities. The UVB is heat and will burn, this causes production of sunburn cells which thicken the skin, coarsening it's texture making it more leather like.
Then there are the infrared rays of warmth that penetrate deeper than UV.
Both UV and infrared pass into the skin and transfer their energy into our skin cells causing the production of damaging free radicals.
This is where antioxidants come in. They donate one of their own oxygen molecules to correct the free radical imbalance thus minimising the damage.
Antioxidants like vitamin C and E can be applied every morning in serum form.
I recommend them for everyone to combat the internal and external effects of ageing from sunlight, computers, smoking and pollution.
Then always use a facial sunscreen. One with physical sunscreens like zinc and titanium are best as they reflect the UV off the skin before it penetrates.
The best ranges of antioxidants and sunscreens, with the most clinical data are made by Skinceuticals. CE Ferulic, Phloretin CF and Serum 10 are highly recommended.
Their sunscreens are great, elegant to use, moisturise and protect too. Their new Brightening Sunscren helps correct irregular pigmentation issues too.
Image make great sunscreens, their Universal SPF 30 is recommended
Skinmedica make great sunscreens too
Hope this helps
