Can Vitamin C be mixed with AHAs and BHAs?

In the vast world of skin care, there is often a lot of confusion about chemical acids and their effects in a skin care routine. It seems that some of us are still a little hesitant about using AHAs and BHAs, so the idea of using Vitamin C with them can seem overwhelming, which is understandable. Well, don’t panic now, because we are here to demystify everything, and if we are lucky, by the end of today’s blog post, we will have answered the question: “Can you mix Vitamin C with AHAs and BHAs?”

Before we dive in, though, let’s quickly review what these ingredients are and how they can benefit the skin.

What is Vitamin C?

Vitamin C is a versatile skin ingredient that has been used in the beauty industry for years. It wasn’t until recently that this powerful powerhouse was able to shake off the misconceptions that have surrounded it for many years. This is because it was considered unstable, which means that it can cause various skin irritations and prevent product formulas from working effectively on the skin. With some well-established, stable versions of the ingredient, Vitamin C has gained a large following, including dermatologists, skin care experts, and fans. Here are some examples of the benefits that can be gained from using Vitamin C. If you want to learn more about this clever ingredient, read our detailed blog post.

Vitamin C is rich in antioxidants, which means it fights free radical exposures such as pollution, UV rays and central heating. All of these are known to cause damage to the surface of the skin.

Vitamin C can increase collagen production, ensuring that the skin remains plump, vibrant and youthfully elastic. This is because Vitamin C contains two important enzymes that the skin needs to produce collagen, namely prolyl hydroxylase and lysyl hydroxylase.

Vitamin C fights hyperpigmentation, dark spots and pigmentation on the surface of the skin. It reduces the production of melanin, which appears on the surface and makes dark spots more pigmented. Over time, you will notice a visible difference and improvement in your skin tone.

Vitamin C restores skin radiance, which is due to a combination of its skin lightening benefits. However, with regular use, you will notice a big difference in the look and feel of your complexion.

What are AHAs?

AHAs, also known as alpha hydroxy acids, are a type of chemical exfoliant that have become a favourite among beauty enthusiasts. Depending on their structure, you’ll find them either naturally occurring or synthetically blended into a range of skincare products.

The difference between AHAs and physical exfoliants is that they break the bonds of dead skin cells to the surface of the skin. This allows the acids to remove the built-up dead skin cells without having to physically scrub them off your face. By clearing away unnecessary skin cells, bacteria, dirt, debris, and other impurities from your skin, fresh, vibrant new skin is revealed that is healthy, happy, and radiant.

What are BHAs?

BHAs, also known as beta hydroxy acids, are considered a close cousin of AHAs. They are generally considered more effective, but people with dry, sensitive skin shouldn’t use them because they can be too harsh on the skin.

The main difference between AHAs and BHAs is that BHAs, especially the most commonly used salicylic acid, are oil-soluble and have a smaller molecule size, which means they can penetrate deeper into the skin and reach the lower layers of the skin.

Can Vitamin C be mixed with AHAs and BHAs?

The short answer is: yes, but only if you’re sure your skin is happy with it. What I mean by that is that you need to first make sure you know your skin type before you try to layer these ingredients. Those with oily skin may find it strong enough to use a careful blend of these acids and Vitamin C. However, before you go out and start applying these products to your skin, you should make sure you’re still using these formulas effectively.

The easiest way to mix Vitamin C with AHAs and BHAs is to remember the basic skin rule, apply products from thinnest to thickest formulas. This allows each product to deliver its best results without having to compete with the physical barriers created by thicker formulas. Vitamin C is often found in serums and face oils, so you may choose to use an exfoliating toner rich in AHAs (such as glycolic acid) or BHAs (such as salicylic acid) before applying a serum. Combining this with a moisturizer or other serum rich in hyaluronic acid can help rejuvenate the skin. Hydrating allows the skin to lock in moisture while counteracting possible dryness.

If you notice any signs of redness, increased sensitivity, or skin irritation, it’s best to stop using all three powerhouses in your routine and instead alternate the acids. You can do this by using the acids on different days or at different times of the day, using a vitamin C serum in the morning and your acid of choice at night.

Can BHA and Vitamin C be used together?

Yes, you can, but only if you use each ingredient correctly in your routine. As I mentioned, using BHA and Vitamin C together can be effective, but it can also be very drying to the skin. For best results, you must allow enough time between applications to allow the pH of the skin to balance and avoid unnecessary irritation.

For best results, use an exfoliating toner with a BHA (most likely salicylic acid) after cleansing. Wait about 30 minutes, then follow up with a serum rich in vitamin C, and finish with a moisturizer with hyaluronic acid and other hydrating ingredients.

If you find your skin is still showing signs of irritation, you can also deep cleanse your skin with a BHA product at night after a day of using a vitamin C serum to protect your skin from free radical damage.

Can AHAs and BHAs be mixed with hyaluronic acid?

Of course, the beauty of hyaluronic acid as a skincare ingredient is that it works seamlessly with a variety of other ingredients, even powerful ones like salicylic acid and glycolic acid. When layering these powerful ingredients, it is generally considered best to use hyaluronic acid after using an exfoliating acid, as this ensures that any potential dryness is prevented. Instead, the skin benefits from moisture being locked into the face and the protective skin barrier working with the right amount of water. This keeps the skin healthy and protected from free radicals and other environmental impacts.

Can glycolic acid and vitamin C be used together?

Yes, you can use glycolic acid and vitamin C together, but you should know what you are doing! Glycolic acid and vitamin C are an effective combination if you have issues with dull, lackluster skin, are noticing signs of hyperpigmentation and dark spots, or are experiencing signs of aging.

You can achieve amazing skin results if you use these ingredients in a staggered manner, as this will help rebalance the pH of your skin and prevent irritation. We have detailed how to use glycolic acid and vitamin C together in a dedicated blog post here at Beauty Insiders.

How do salicylic acid and vitamin C work together?

The difference between salicylic acid and glycolic acid is that salicylic acid has a significantly smaller molecule size. This allows it to penetrate to the bottom of the pores to remove dirt, bacteria, excess sebum, and other impurities. You will often find that salicylic acid is very effective, but it often causes skin irritation. Glycolic acid is also very effective, but due to its larger molecule, it works mainly on the outer layer of the skin.

How to use salicylic acid and vitamin C together depends on your skin type and the daily routine you have already established. This is because, as I mentioned before, enough time must pass between using these ingredients, otherwise you should choose alternating times to achieve results without causing unnecessary irritation to your skin.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
