Can You Use Retinol and Vitamin C Together?
On Combining Powerhouse Ingredients for Optimal Skin Results.
When you’re just starting your anti-aging routine, combining powerhouse skincare ingredients like retinol and vitamin C can seem daunting.
These ingredients are rightfully celebrated for their transformative effects on our skin, and yet, there's a common belief that they can't be used together.
In this article, I want to dispel that myth and teach you everything you need to know about using retinol and vitamin C together to get the flawless, youthful skin you’ve always dreamed of.
So, let's dive into the science behind these ingredients, explore their benefits, and uncover the truth about their compatibility.
Understanding Retinol
Retinol, a derivative of vitamin A, is one of the most researched and proven anti-aging ingredients in skincare.
It accelerates skin cell turnover, stimulates collagen production, and helps to diminish fine lines, wrinkles, and hyperpigmentation.
That last one is sneaky - in fact, I think one of the first signs of premature aging isn’t the development of fine lines but rather uneven skin tone.
This includes melasma, dark spots, and other pigmentation abnormalities.
How Retinol Works
Retinol works by promoting the production of new skin cells and increasing the rate at which these cells move to the surface.
This process helps to shed dead skin cells and reveal fresher, more youthful skin underneath.
Over time, retinol can significantly improve your skin texture, skin tone, and overall appearance.
Potential Side Effects and Considerations
Despite its benefits, retinol can cause side effects, especially when you first start using it.
These can include dryness, redness, and peeling.
In my case, because I started my retinol journey right before summer hit years ago, I got slightly sunburned around my eyes because retinoids increase your skin’s sensitivity to ultraviolet radiation.
It's essential to introduce retinol gradually into your routine and use it in conjunction with a moisturizer to mitigate these effects.
My advice: Start with a low concentration of retinol, such as 0.3% as found in CeraVe’s Resurfacing Retinol Serum, and apply it every other night. Gradually increase the frequency and concentration as your skin builds tolerance.
Understanding Vitamin C
Vitamin C, also known as l-ascorbic acid, is a potent antioxidant that offers numerous benefits for the skin.
It helps brighten your complexion, even out skin tone, and it can even protect your skin against environmental damage by neutralizing free radicals.
How Vitamin C Works
Vitamin C works by neutralizing free radicals, which are unstable molecules that can damage skin cells and accelerate aging.
Additionally, vitamin C inhibits melanin production, which reduces hyperpigmentation and brightens skin.
Finally, it also boosts collagen production, contributing to firmer, more youthful skin.
Potential Side Effects and Considerations
Vitamin C is generally well-tolerated, but it can cause irritation in some individuals, particularly at higher concentrations.
Interestingly, I find that it’s not necessarily l-ascorbic acid (pure vitamin C) itself that’s the issue - rather, it may be because l-ascorbic acid is so finicky that to stabilize it, some formulas have a particularly low pH.
It's also sensitive to light and air, so it's crucial to choose stable formulations and store them properly to maintain efficacy.
My advice: If you want the best of the best, look for vitamin C products with l-ascorbic acid in airtight, opaque packaging to ensure stability such as Naturium’s Vitamin C Complex or Stratia’s C+C Serum. Otherwise, more stable forms of vitamin C include sodium ascorbyl phosphate as found in MaeLove’s Glow Maker and tetrahexyldecylascorbate as found in The Ordinary’s Tetraisopalmitate in Vitamin F serum.
The Compatibility Question
There has been a long-standing myth that retinol and vitamin C cannot be used together because they might deactivate each other or cause excessive irritation.
However, evidence debunks this myth, showing that these ingredients can be effectively combined with proper formulation and application.
Benefits of Using Retinol and Vitamin C Together
Combining retinol and vitamin C can provide several enhanced benefits for your skin:
Enhanced Anti-Aging Effects
Both retinol and vitamin C stimulate collagen production, which can improve skin firmness and reduce the appearance of fine lines and wrinkles.
Using them together can amplify these effects, leading to more significant improvements in skin elasticity and youthfulness.
Improved Skin Texture and Tone
Retinol accelerates cell turnover, while vitamin C brightens the skin and reduces hyperpigmentation.
Together, they can create a smoother, more even complexion.
Give it a few months, and you'll notice a reduction in dark spots and an overall brighter skin tone.
Increased Collagen Production
Collagen is essential for maintaining skin firmness and elasticity.
Both retinol and vitamin C promote collagen synthesis, which helps keep our skin looking youthful and resilient.
Combining these ingredients can maximize collagen production, resulting in firmer, plumper skin.
My advice: To reap these benefits, ensure that you're using stable formulations and introducing them gradually into your routine. This will help your skin adjust and minimize potential irritation.
How to Incorporate Both into Your Routine
Incorporating both retinol and vitamin C into your skincare routine requires a strategic approach to avoid irritation and maximize benefits.
Tips for Using Them Together Without Irritation
Start Slowly: Introduce one ingredient at a time instead of both. I suggest starting by incorporating retinol into your routine for a few months before adding vitamin C.
Layering: Use vitamin C in the morning and retinol at night. This separation helps to minimize potential irritation and allows each ingredient to work optimally.
Alternate Nights: If you have sensitive skin, you might prefer to alternate between retinol and vitamin C on different nights rather than using them on the same day.
Morning vs. Evening Application
Morning: Apply a vitamin C serum after cleansing and before moisturizing and sunscreen. Vitamin C provides antioxidant protection during the day, neutralizing free radicals caused by UV exposure and pollution and working synergistically with your SPF.
Evening: Apply retinol after cleansing and before moisturizing. Retinol works best overnight, when your skin's repair processes are most active.
Further, retinoids degrade under sunlight, so it wouldn’t make sense to apply them in the morning anyhow!
My advice: Consistency is key. Stick to your routine with retinol in the evening and vitamin C in the morning, and give your skin time to adjust to the new ingredients.

Potential Side Effects and How to Avoid Them
Combining retinol and vitamin C can occasionally lead to side effects, but there are strategies to minimize these risks.
Common Issues
Irritation: Both ingredients can cause dryness and irritation, especially when first introduced.
Sensitivity: Skin may become more sensitive to the sun, making sunscreen even more critical.
Strategies to Minimize Irritation and Sensitivity
Gradual Introduction: Start with lower concentrations and gradually increase as your skin builds tolerance.
Hydration: Use a hydrating serum or moisturizer to combat dryness and support the skin barrier.
Sunscreen: Since retinoids sensitize your skin to the sun, consider applying a broad-spectrum sunscreen during the day to protect your skin from UV damage.
My advice: If irritation occurs, reduce the frequency of application and focus on hydrating and soothing products until your skin adjusts.
A Real-Life Example
When I first started using retinol five years ago, it wasn't for anti-aging but rather because I had acne-prone skin and closed comedones on my forehead.
I began with CeraVe's Resurfacing Retinol Serum, which I used for about a year.
This was a great introduction to retinol, and it significantly improved my skin texture and reduced my acne.
After that, I graduated to adapalene 0.1% (Differin), a retinoid specifically designed to treat acne.
Adapalene helped to further clear my skin, and I used it for a few years while testing various retinol and retinal serums for you guys.
Eventually, I upgraded to tretinoin, the older sister of retinol.
When you apply retinol to your skin, it undergoes two conversion steps to become retinoic acid, the same as tretinoin.
Therefore, retinol is less effective than tretinoin in fighting aging but also far less irritating.
Now, I use tretinoin nearly every night and can layer exfoliants or other actives with it.
It has dramatically improved my skin, making it smoother, firmer, and more even-toned.
