vitamin · for sunburn & sun sensitivity
Nicotinamide
The gentler face of vitamin B3 — it does not cause the hot, prickly flush that plain niacin can. You will meet it far more often in a face cream than in a capsule. We have not reviewed it yet.
How strong is the research?
Not verified evidence
47 healthy volunteers with fair skin took oral Polypodium leucotomos for 30 days. It took 29% more UVB light to redden their skin. DNA damage from UVB did not change. Nicotinamide, tested in the same study, gave no burn protection.
