The best for your skin is not what you smear on the outside, but what you give it from the inside through the food you eat. Seafood is beneficial to the skin in a number of ways:
Seafood has a preventive effect against eczema. Studies show that babies who have consumed seafood before the age of nine months have a lower risk of developing eczema than those who have not consumed seafood by this age.
Seafood has a protective effect against ageing because marine omega-3 fatty acids protect the skin against UV rays from the sun, while antioxidants counter free radicals that attack skin cells and provoke ageing.
