J'adore NIA24 Sun Damage Prevention Mineral Sunscreen SPF 30! I have been using it for 4 years now. When I first moved to Cayman I was using another light moisturizer with SPF15 sunscreen but I found that I needed to move up to a higher SPF.
The key ingredient in NIA24 products is Nicotinic acid (Pro-Niacin) which stimulates the release of a hormone leptin, a natural repair hormone, that aids healing with the skin cells and aids in the reduction of hyper pigmentation.
I usually order it online but there is currently a back log of some sort : ( I scoured the streets of NYC desperately looking for it everywhere. Finally, one dermatologist told me that the company itself had the back log and not specifically any retailer. Anyway, looking forward to it coming back soon!
