Can You Use Vitamin C and Retinol Together?

Vitamin C and retinol are two of the most potent over-the-counter anti-agers available. Vitamin C is a potent antioxidant that can help protect your skin from free radical damage and maintain healthy collagen levels.

Retinol exfoliates the skin to promote cell turnover and decrease wrinkle formation, so together, they double down on anti-aging benefits.

But if they are such great anti-agers, can you use vitamin C and retinol together? Do the two cancel each other out?

The answer is that it is possible to use vitamin C and retinol together, just not at the exact same time. It’s best to apply vitamin C, then wait for about 30 minutes before applying retinol.

This gives the vitamin C enough time to absorb into your skin and for your skin’s pH to return to normal before retinol is applied.

Even better, apply vitamin C in the morning and retinol at night or use these two actives on different days of the week. Let’s take a look at why these two all-star actives deserve a spot in your skincare routine in the first place.

The Benefits of Vitamin C for Skin

Vitamin C serums from Paula's Choice, Acure, CeraVe and Klairs

Vitamin C, also known as ascorbic acid or l-ascorbic acid, is one of the most powerful antioxidants in skincare, and it continues to gain popularity with skincare enthusiasts everywhere.

If you’re wondering how vitamin C can benefit your skin, here’s a quick look at some of its top benefits:

Antioxidant Benefits

Vitamin C protects the skin from sun damage with its powerful antioxidant properties. (That is why I love to use vitamin C products during the day under my sunscreen).

UV damage is one of the main causes of visible signs of aging like fine lines and wrinkles, so using an antioxidant like vitamin C can help prevent this type of damage.

It also protects against other environmental aggressors like pollution.

This study demonstrated that ferulic acid doubles the photoprotective abilities of vitamin C and vitamin E, so that’s why you’ll often see these three actives in the same formula.

Boosts Collagen Production

Ascorbic acid can boost collagen production, keeping skin firm, tight and toned, while helping to reduce wrinkles and fine lines. Collagen helps our skin look firm and plump, something that’s especially important as we age.

Fades Age Spots and Hyperpigmentation

Vitamin C helps fade hyperpigmentation, dark spots, and uneven skin tone. It interferes with the enzyme tyrosinase, which produces melanin, the pigment in our skin.

Vitamin C can also help fade acne scars or what’s also known as post-inflammatory hyperpigmentation. They are those pesky dark spots that are leftover from old acne breakouts.

The Drawbacks of Vitamin C

Along with these benefits of Vitamin C, there are some drawbacks. Vitamin C can be sensitizing and cause irritation and redness when used at higher concentrations.

Those with sensitive skin may want to stick to concentrations under 10% or use a vitamin C derivative.

Another drawback of vitamin C is that it is notoriously unstable. Vitamin C oxidizes when exposed to air, light, and heat, which reduces its effectiveness.

When using a vitamin C product that contains ascorbic acid, it’s most effective when used within three months of opening.

Luckily, many vitamin C derivatives are formulated to be stable and non-irritating. Even better, many have a pH that is compatible with retinol, so you can use them at the same time as retinol in your skincare routine.

The Benefits of Retinol for Skin

Retinol products from Olay, Paula's Choice, The Ordinary and Neutrogena

Retinol is arguably the most powerful over-the-counter anti-ager available. Retinol encourages cell turnover to remove dead skin cells and encourage new, healthy growth.

Retinol is a type of retinoid and form of Vitamin A. It is commonly used in anti-aging skincare products to improve the signs of photodamage, including fine lines, hyperpigmentation, blackheads, and dull skin tone.

Retinol is converted to retinoic acid when applied to the skin. It takes two conversions to transform retinol into its active form of retinoic acid. Retinoic acid is available in prescription form as tretinoin.

While not as potent as prescription retinoids like tretinoin, retinol effectively addresses the signs of aging with less irritation, dryness, and peeling. The benefits of retinol include:

Boosts Collagen Production

Retinol increases epidermal thickness and stimulates collagen production, helping to smooth fine lines and wrinkles. It improves skin smoothness, firmness, and elasticity.

Treats Acne

Per the American Academy of Dermatology (AAD), retinoids are an effective treatment for acne. Retinol inhibits the formation of comedones, is anti-inflammatory, and normalizes keratinization, which keeps your pores from getting clogged. Clogged pores can eventually lead to breakouts and acne.

Fade Hyerpigmentation, Age Spots and Sun Spots

Retinol increases cell turnover, which means it brightens dull skin and helps fade hyperpigmentation, uneven skin tone, age spots, sun spots, and other discoloration.

It also helps to improve skin texture as newer, fresher cells are revealed.

The Drawbacks of Retinol

Depending on your skin type, retinol can cause irritation, peeling, redness, and dry, flaky skin. When first starting out with retinol, it is important to slowly incorporate it into your skincare routine.

Consider starting with once a week for a week, then twice a week for two weeks, then increasing usage to three times a week for three weeks. Then increase usage to every other day or daily as your skin can tolerate it.

It is important to note that retinol and retinoids can make your skin sensitive to and degrade in sunlight, so they are best used in your evening skincare regimen.

You should apply a broad-spectrum sunscreen with an SPF of 30 or higher when using retinol and retinoids and for a week after.

Can You Use Vitamin C and Retinol Together?

When discussing mixing actives, the topic of pH often comes into play. PH measures how alkaline or acidic a solution is.

A pH below 7.0 is considered acidic for facial products, while a pH above 7.0 is considered alkaline. (Water is neutral at pH of 7.0.)

The ideal pH for a vitamin C serum is between 3.0 and 3.5, while the optimal pH of retinol falls between 5.5 and 6.0. Traditionally, the assumption was that applying a vitamin C product and following with retinol would degrade the actives, making them less effective.

Since retinol performs optimally at a pH of 5.5-6.0, and vitamin C should be formulated at a pH under 3.5 for the best absorption, using vitamin C and retinol together would logically reduce the effectiveness of both.

But there are conflicting opinions on this.

This clinical study suggests that using vitamin C with retinol is effective at treating photoaging.

Regardless of pH concerns, if you have sensitive skin, using vitamin C and retinol together at the same time may be too irritating for your skin.

How to Use Vitamin C and Retinol Together

✅ For best results, consider applying vitamin C in the morning when its antioxidant properties will protect the skin from ultraviolet rays and damage from radicals, and use retinol at night.

✅ You can also alternate days and use vitamin C one day and retinol the next day.

✅ If you really want to use them in the same skincare routine, apply vitamin C and let it absorb for about 30 minutes, and then apply retinol after your skin’s pH has had a chance to normalize.

Vitamin C Derivatives

One other option is to use a vitamin C derivative with retinol (or another retinoid).

Vitamin C derivatives are usually formulated at a higher pH than pure vitamin C, making them more tolerable when used with retinol. However, they still provide many of the same benefits of vitamin C.

Vitamin C derivatives like tetrahexyldecyl ascorbate (found in Acure Brightening Vitamin C & Ferulic Acid Oil Free Serum below) are less acidic than pure Vitamin C.

They can be applied directly to the skin without causing irritation or stinging. You can use it at the same time as retinol without interacting adversely with it.

TIP: Don’t forget about your neck and chest when applying your vitamin C and retinol products. Just like the rest of your face, these areas also show signs of aging and need some extra love through skincare.

Just be aware that your neck and chest may be more sensitive than your face, so be sure to patch test before trying new products for the first time.

Final Thoughts Using Vitamin C and Retinol Together

The bottom line is that you can use vitamin C and retinol together if you don’t have sensitive skin and as long as you wait for about 30 minutes in between the application of the two.

Can you use vitamin C in the morning and retinol at night?

Absolutely! Using vitamin C in your morning skincare routine will help protect you from damaging UV rays, and retinol will work its magic overnight (and away from the sun).

Whether you use vitamin C, retinol, or both, be sure to apply a broad-spectrum sunscreen every morning to protect your skin from harmful UV rays.
