When vitamin C acts as a pro-oxidant, the consequences include irritation, inflammation, collagen and elastin breakdown, and acne. So if you have any of these skin ailments, and are using a vitamin C serum, then its time to re-think your regimen.
If after 24 hours, you develop redness, itching or a rash on your face, discontinue using that particular vitamin C serum.
Take note of the characteristics of your serum when you first begin using it. Once your product changes color, texture, smell, or becomes cloudy, you need to discontinue use immediately, as it has oxidized and therefore expired. Vitamin C serums typically have a shelf life of around six months to a year after opened.
Vitamin C serum is typically applied once or twice per day. A good rule of thumb is to cleanse, tone, apply vitamin C serum, and then moisturize. It can be safely used with other active ingredients, although using alongside niacinamide may make vitamin C less effective.
Vitamin C serums are legendary for a reason: They really work. Uneven skin tone, rough texture, fine lines, acne scars, general dullness — you can name just about any common complexion concern and there's a good chance that vitamin C (and the skin-care products it's featured in) is a recommended treatment.
No, you can start using Vitamin C serum once you are 20.
No, it does not. It may stain your skin but it cannot darken your skin. It is important to know the difference between staining and darkening the skin. Staining is where the product reacts with your dead skin cells and leads to a change in the color of those dead cells.
For those with sensitive, reactive skin, certain forms of vitamin C can be shockingly irritating, leading to dryness, peeling, and redness. But you shouldn't bin your vitamin C serums or moisturizers right after reading that.
There's no proof that Vitamin C causes acne. In fact, it may even help treat it faster! And yet, many of my clients with oily, acne-prone skin complain their acne got worse after introducing a Vitamin C serum into their skincare routine.
“I definitely recommend serums for anyone who is concerned about aging. It's a really good way to get extra anti-aging effects, more than your typical moisturizer and sunscreen,” says Dr. Waldman.
Can You Use Hyaluronic Acid and Vitamin C Together? Not all powerful skincare ingredients can be mixed, but hyaluronic acid and vitamin C are two that become even stronger when paired with one another. These ingredients can provide both immediate and lasting results when used together in anti-aging formulations.
Since serums contain the active ingredients that you want to penetrate as deeply as possible into your skin, you should always apply a serum directly to your skin after cleansing or toning and before your moisturizer and sunscreen. Don't put your serum on after you moisturize.
If you are applying a Vitamin C serum and hyaluronic acid separately, it's suggested that you apply the Vitamin C first, and then add the hyaluronic acid afterward in order to help fortify the skin barrier and lock in the moisture.
So if you used a vitamin C serum and it gave you acne, redness or any other skin issue, it is because the serum took away your body's ability to fight off bacteria, and weakened it, inviting pathogens to infect your skin.
Many serums are yellow, but if your product takes on a brown or dark orange hue, it's time to toss because it's gone bad. If your serum starts out clear and turns yellow, that's also a sign it's oxidizing and will be less effective.
Best overall vitamin-C serum
Four of our dermatologists recommend SkinCeuticals C E Ferulic, which they (and our editors) hail as the gold-standard vitamin-C serum and is suitable for all skin types.
Even if you don't have sensitive skin, we recommend that all skin types use their vitamin C serum before bed. Your body undergoes its natural repair process while you're asleep, and the vitamin C will make its strongest impact on your skin during this time.
"Products with niacinamide and vitamin C will help lighten dark underarms," Dr. Jaliman points out. "You don't want to use strong ingredients since the skin under your arms is a sensitive area." "This cream is gentle and contains vitamin C (which lightens) and vitamin E (which is moisturizing)," Dr.
Vitamin C is a great all year-round cream, especially during the summer.
Dr Sharad lays down the rules. It is imperative to use a moisturiser and sunscreen every single day. These are your first anti-ageing products which you should start in your teens. At 25, you can start using a vitamin C serum but do a test patch if you have acne-prone skin.
