Pure vitamin C is also known as ascorbic acid. It's a powerful antioxidant that helps protect your skin. It also helps your skin make collagen, which keeps it firm.
When vitamin C is in skincare products, it can be helpful at different concentrations. If it's between 5-25%, it's great for fighting signs of aging like wrinkles or discoloration and making your skin more elastic. It can also brighten dull skin and even out your skin tone.
If it has less than 2%, it can still make your skin look better by improving its tone, making it stronger, and giving it more protection.
This ingredient doesn't like light and heat. So, if you have a product with a lot of vitamin C, keep it in a cool, dark place. You can even store it in the fridge when you're not using it.
High-concentration vitamin C products have a low pH, around 3-4. This makes vitamin C work better and last longer.
Vitamin C can sometimes make your skin tingle a little when you use it, especially if it's strong. This is normal, but if it makes your skin red or irritated, stop using it.
It can work even better when it's mixed with other vitamins like retinol and niacinamide. But, if your skin is sensitive, it's better to use vitamin C/retinol/AHA on different days, not all at once.
