Morning power
Vitamin C fights free radicals and boosts SPF—apply after cleansing, before moisturizer.
Look for L-ascorbic acid or stable derivatives; pair with vitamin E and hyaluronic acid.
Storage matters
Keep bottles away from light and heat. If the serum turns dark orange, it may have oxidized.
Start every other morning if tingling occurs—build tolerance over two weeks.
