It’s quite a sensitive & complex subject, as such we will do our best at providing a clear and concise article to clear any doubts you may have.
Healthy Fats
Focus on monounsaturated and polyunsaturated fats from plants like nuts, seeds, and avocados and from fish.
Vitamin A
Both the upper and lower layers of skin need vitamin A. It seems to prevent sun damage by interrupting the process that breaks down collagen.
Since it’s an antioxidant, it may give your skin some protection against sunburn (although not as much as wearing sunscreen). It helps the oil glands around your hair follicles work and may also help cuts and scrapes heal, especially if you’re taking steroids to reduce inflammation.
Can Ingesting Vitamins Help Your Skin?
But vitamins have not always been vitamins.
Then a Polish biochemist named Casimir Funk (yes, the best name ever, we know) came along. He was studying beriberi disease, and realized all the sufferers were deficient in what’s now called vitamin B1 or thiamine. Casmir coined the term himself: After realizing these nutrients were essential to human function, he chose the name “vital amines,” with vital coming from the root word “vita” meaning “life” in Latin.
If you’re deciding which ones to ingest, we suggest consulting a doctor or nutritionist. But if you’re looking to figure out the difference between a vitamin C serum and a vitamin A-derived retinol cream, knowing the benefits of each can empower you to make the best choice for your skin. Vitamin-enriched skin-care products can protect against free-radical damage, treat fine lines and wrinkles, and lessen hyperpigmentation.
B-Complex Vitamins
Several B-complex vitamins may improve skin health. Not all research has found such benefits, though many studies suggest that B-complex vitamins are most effective when people apply them directly to the skin. Some studies suggest that it may help reduce the appearance of age spots and other forms of skin discoloration.
A randomized controlled trial from 2014 found that people who took a B-5 dietary supplement for 12 weeks saw significant reductions in acne and skin inflammation. The cream improved skin tone and texture within 6 weeks. It also helped with age spots and hyperpigmentation.
Some dietary sources of B-complex vitamins include meat, eggs, seafood, nuts, and seeds.
