What the gurus are saying

Gurus overwhelmingly endorse vitamin C for anti-aging, brightening dark spots, and boosting sunscreen protection. A key consensus point is stability: vitamin C is effective but unstable, requiring careful formulation and application on completely dry skin to prevent irritation. Gurus also dispel the myth that vitamin C and niacinamide are incompatible, confirming they work well together. The recurring advice is to apply in the morning for maximum benefit.

"There's other things that build collagen like vitamin C peptides."

"Because vitamin C is relatively unstable it can be problematic with a lot of different things if not considered. People wonder about combining it with niacinamide because there are tons of posts on social media saying you shouldn't combine them, but that misconception is based on very old data and it has been dispelled time and time again. Vitamin C and niacinamide are completely fine together and in fact they actually work quite nicely together to combat hyperpigmentation."

"Vitamin C helps decrease the signs of aging and helps brighten the dark spots. It increases potent of your sunscreen by up to eight times and it does this by preventing the free radical formation that we get from the UV light, therefore helping the sunscreen work better. So not only are you going to slow down the aging process of fine lines and wrinkles, you're also going to brighten your brown spots by using vitamin C underneath your sunscreen in the mornings. Vitamin C is extremely important in my opinion to be used, and while you can use it twice a day, in the morning is a must. The best benefit of vitamin C will be seen by applying it in the mornings. Vitamin C should be applied in the morning to dry clean skin, and making sure that your skin is dry before you apply vitamin C is extremely important, especially if your skin is sensitive, because when your skin is a little bit damp from moisture it's more prone to irritation."

"Vitamin C is proven to reduce redness, proven to reduce pigmentation as well, and it works synergistically with some of these ingredients. It works synergistically with AHA acid and if you're already on a retinol and you're happy with it post scarring, then it works even better with vitamin C, which is fantastic."
