A tell-tale sign of vitamin c over-use can be increased blackheads or a development of blackheads. General skin irritation and breakouts can also occur if you are using your vitamin c too much or too often. We recommend using your serum 1-2 times a day and 2-4 drops is all that is needed.
7 vitamin C serums to consider
Sometimes it can be too strong for your skin, causing it to react via purging, breakouts, or itchiness. You don't want the product to sting and itch even after you apply moisturizer.
"Plus, vitamin C is often combined with other antioxidants, including vitamin E (tocopherol). Even though the combination of C and E has been shown to have greater skin benefits than either vitamin alone, vitamin E is oil, so the combination can cause breakouts for people who have acne-prone skin."
Anything that makes your skin cells turn over faster can cause skin purging, so generally those with exfoliating benefits, such as retinoids (Vitamin A), Vitamin C (a very gentle acid that can slough off dead superficial skin) and hydroxy acids (glycolic acid, malic acid and salicylic acid).
Sudden acne breakouts can be because of numerous reasons, including hormonal changes or hormonal imbalance, an unhealthy diet including lots of deep fried and junk food, release of cortisol hormones because of excessive stress, excessive production of sebum and much more.
Dr. Chiu warns that because vitamin C is a skin-care “active”—meaning it's particularly potent—applying too much of it on your face can potentially lead to more breakouts or irritation. Keep it to a max of two applications a day when a formula that has no more than 10% vitamin C each time.
Vitamin C can be very acidic, and serums can cause skin irritation in some people, particularly in high concentrations.
What are the side effects of Ascorbic Acid (Vitamin C)? Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
If your skin gets too itchy, red or irritated from using a Vitamin C serum, this might mean the percentage of Vitamin C is too high for your skin. In particular if you have sensitive skin, you will definitely need a Vitamin C serum that has a lower concentration, for example 10%.
This incredible antioxidant, anti-inflammatory nutrient is known to improve skin tone and texture, hydrate the skin, and reduce signs of aging. Adding vitamin C to your skin care routine can not only brighten your complexion but also protect against skin damage caused by sun exposure and harmful free radicals.
Acne can be caused or aggravated by supplements, even seemingly innocuous supplements. The main culprits causing breakouts are supplements containing Vitamins B6/B12, iodine or whey, and 'muscle building supplements' that may be contaminated with anabolic androgenic steroids.
Purging is a sign that the product is working and you should continue with the treatment as prescribed. After a few weeks of purging, your skin and acne will have noticeably improved. Breaking out is when your skin is reacting because it is sensitive to something in the new product.
Skin purging typically looks like tiny red bumps on the skin that are painful to touch. They are often accompanied by whiteheads or blackheads. It can also cause your skin to become flaky. The flare ups caused by purging have a shorter lifespan than a breakout.
Skin purging occurs because newly introduced skincare ingredients increase the rate at which your skin cells turnover, causing you to shed more dead skin cells than usual. This, in turn, pushes layers of dead skin off and also brings clogged pores to the surface, Chang says, resulting in more breakouts.
Purging can last for anything from one or two weeks to one or two months. Breakouts can last a while; there is no time period that indicates when the breakouts will go away. The cell turnover speed is usual. The purging of the skin starts after a few days of using a new product.
Most niacinamide products also contain a variety of other ingredients. If any of these ingredients increase skin cell turnover then they may be behind any 'purging'. Some ingredients can also be 'comedogenic' which means that they are more likely to clog pores and cause breakouts.
How to treat skin purging. “If the skin barrier is compromised when you see purging then start ingredients which help with barrier repair, such as ceramides and hyaluronic acid in a non-comedogenic formulation. If you are using a treatment or product continue with a slower approach.”
A number of dietary supplements have also been linked to acne, including those containing vitamins B6/B12, iodine, and whey, as well as "muscle building supplements" that may be contaminated with anabolic-androgenic steroids (AAS).
Summary. Large doses of vitamin B12 can trigger a cobalt allergy. That may cause a red, painful rash called contact dermatitis. Most cobalt exposure is from makeup, industrial uses, and B12 supplements.
AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with Vitamin C. Vitamin C is an acid, too, and is unstable, so the pH balance will be thrown off by layering these ingredients together and might as well be useless.
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.
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.
Vitamin C (especially L-ascorbic acid) is notoriously unstable—it loses potency when it's exposed to air, light, and water—which is why you want to apply it on clean, dry skin right after washing. You'll also want to let it dry completely, as piling on products right after could potentially deactivate the vitamin C.
