Question 1

Does beta-carotene help protect skin from the sun?

Accepted Answer

Yes, beta-carotene provides mild internal UV protection by accumulating in the skin and acting as an antioxidant. Studies show that 12-24 mg of beta-carotene per day for 10+ weeks reduces skin sensitivity to sunlight. It does not replace sunscreen but complements external protection from within.

Question 2

Can beta-carotene turn your skin orange?

Accepted Answer

Yes, long-term consumption of very high doses (over 30 mg per day) can cause carotenodermia — a yellowish-orange discoloration of the skin, especially on palms and soles. This is harmless and disappears when the dose is reduced. At normal doses (6-15 mg), beta-carotene gives a healthier skin tone.

Question 3

Should smokers take beta-carotene?

Accepted Answer

Smokers and former smokers should be cautious with beta-carotene supplements. Two large studies (ATBC and CARET) showed that high-dose beta-carotene (20-30 mg per day) increased lung cancer risk in smokers. For smokers, it is safer to obtain beta-carotene from food rather than supplements.
