VITAMIN C

What is it?

Easily the most well-known antioxidant in skincare, vitamin C (also known as L-ascorbic acid) is an absolute must for brightening your overall skin tone, lightening acne scars and dark spots and providing skin with a shield-like layer of protection from pollution and particulate matter (tiny particles in the air like pollen and dust). Fun fact: Vitamin C is actually the number-two rising Google search for all face care topics worldwide (right behind retinol). So if you haven’t already, it’s time to get acquainted with this powerhouse.
How should it be used?

Once daily is enough, says Dr. Kellett, but whether you use it in the morning or at night depends on what other products and ingredients you’re using. For example, you definitely won’t want an oil-based cleanser to block your water-based vitamin C serum from absorbing into skin—a good rule of thumb when using any combination of oil-based and water-based products, of course, but especially with (usually) pricey vitamin C serums—you don’t want to waste any of this gold.

It’s also a good idea to avoid using vitamin C at the same time as exfoliants like retinol, BHAs and AHAs, which can sometimes lead to redness, flaking and irritation, and is why most people tend to use a vitamin C serum in the morning, and other chemical exfoliants in the evening. Bonus: Layering a vitamin C serum under your sunscreen during the day adds extra protection from the sun’s UV rays, pollution, dust and more. Remember that shielding ability we mentioned above? Trust us—you want to take advantage of it.
What should consumers be on the lookout for?

“[A concentration of] 20% or higher is most efficacious,” says Dr. Kellett, adding that “serums tend to be a more effective delivery.”

Lol, how this uninformed world is easily made lighter of their money. Just use cheapest ascorbic acid powder (if irritating some mineral ascorbate) and mix with DSMO solution. No other additives or presevatives needed.
