.
2. Reduce potential skin cancer (niacinamide studies) reduce solar keratosis rate 23 to 40%.
.

.
4. Reduce inflammation & oxidative stress;acne (free fatty acids) rosacea Vitiligo, psoriasis, lupus
.
How to start skin care? The mainstream antioxidants include

.
Silimarin: derived from milk thistle, this antioxidant can help with acne & reduce the incidence of post acne marks
.
Resveratrol via grapes, berries. Studies have shown that resveratrol can reduce the risk of heart disease, cancer and neurodegeneration. Resveratrol to activates the sirtuin genes which protect our DNA

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. They are also available as dietary supplements. Examples of antioxidants include:

Beta-carotene
Lutein
Lycopene
Selenium
Vitamin A
Vitamin C
Vitamin E

Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet with lots of vegetables and fruits is healthy and lowers risks of certain diseases. But it isn’t clear whether this is because of the antioxidants, something else in the foods, or other factors.

High-dose supplements of antioxidants may be linked to health risks in some cases. For example, high doses of beta-carotene may increase the risk of lung cancer in smokers. High doses of vitamin E may increase risks of prostate cancer and one type of stroke. Antioxidant supplements may also interact with some medicines. To minimize risk, tell you of your health care providers about any antioxidants you use.
