As a beauty shopping editor, I’ve talked many times with dermatologists and estheticians about skincare routines. What do they always recommend? Vitamin C. The serum’s formula smells like a hot dog, but this antioxidant is almost an all-in-one, targeting hyperpigmentation, fine lines, and sun damage. However, there are many things to consider when trying it out. Because no one wants to break down their skin barrier, we reached out to Dr. Angela Lam, Dr. Dusan Sajic, Dr. Loretta Ciraldo of FAAD, and Dr. Ashley Magovern. Help you choose the right vitamin C serum for your face.
Before you fall in love with the cute packaging, you should check the ingredient list. There are many different types of vitamin C, but which one is the most effective? Because L-ascorbic acid is irritating and unstable, L-ascorbic acid, especially between 10 and 20 percent, should not be used. Masu.
Another form of vitamin C is tetrahexyldecyl ascorbate. Ciraldo prefers this because it is more stable and less irritating than L-ascorbic acid. Furthermore, it is effective against fine wrinkles and collagen. She recommends finding a ratio of 2 to 3. Last but not least, we have ascorbyl glucoside. This is another more stable and less irritating form of vitamin C that is easily absorbed into the skin. (Don’t worry about taking notes; we have lots of recommendations below.)
yes. Vitamin C is sensitive to light and air, so improper packaging can speed up oxidation and reduce its effectiveness. A rule of thumb that our experts agree on is that vitamin C serums should be placed in dark or colored bottles with a dropper to keep out light and air.
Since it is a very sensitive ingredient, it is best to avoid placing it in a beauty cabinet that is exposed to sunlight. (Sorry!) “It’s important to store it in a dark, cool place, away from sunlight and heat,” explains Sajic. If you have a skincare fridge or are looking for an excuse to buy one, that’s also a good option, says Lam, especially if you want to be careful.
Vitamin C does not need to be taken immediately and can be taken daily. Use in the morning (after cleansing and before moisturizing) several times a week, depending on skin tolerance and serum concentration. And as always, be sure to apply sunscreen when you’re done.
The most important question of them all. Everyone wants to get smooth, clear skin quickly, but layering ingredients on top of each other can have the opposite effect. Here is a summary of ingredients to avoid when using vitamin C serums:
– Retinol: If you’re using retinol and vitamin C as part of your nightly routine, Lam recommends alternating your nights or using your vitamin C serum only in the morning.
– Exfoliant: These are alpha hydroxy acids (AHA) and beta hydroxy acids (BHA). “Avoid combining vitamin C with alpha hydroxy acids (AHAs), such as benzoyl peroxide and glycolic acid, as they can cause irritation,” Sajic explains. For maximum results, simply switch up the days you use the product.
Lam explains that people with sensitive skin may experience irritation from vitamin C serums. So it might be best to approach it with caution.If you don’t want to take the risk If you want to ditch vitamin C serums altogether, Lam says niacinamide is a good alternative. “Vitamin C and niacinamide both reduce damage from environmental factors, but niacinamide is gentler,” she says.
“Vitamin C is a great ingredient for preventing acne and residual blemish marks,” explains Dr. Magovern. “This active ingredient not only reduces inflammation, redness, and hyperpigmentation, but also helps control sebum production that causes acne.”
If you want to use a vitamin C serum for acne, she recommends starting with 15 percent L-ascorbic acid and increasing it to 20 percent. She also suggests starting with a formula that specifically targets acne, like SkinCeuticals’ Silymarin CF, which contains acne-fighting salicylic acid.
