Use Retinol Only at Night and Wear SPF Every Day
"Retinol makes your skin more sensitive to UV rays and sunlight decreases the efficacy of the product," explains Bowe, who instructs patients to only use retinoids at night and be diligent about applying a daily broad-spectrum SPF 30 or higher during the day.
Always apply Retinol products at night, as sunlight can diminish their power. If you're a prescription-strength user, use Retinol as the first layer on your skin after washing your face with a cleansing cream and before applying your anti-aging moisturizer.

Goldenberg's go-to recommendation for timing between serums and moisturizers is about one minute. This wait has the same reasoning: Sixty seconds — give or take — gives each product a moment to delve into your pores.
Rouleau says the best time to use a scrub is in the morning. Overnight you've loosened up dead skin cells with your glycolic acid or retinol products, making the morning a perfect time to brush them off.
Retinoids work best if you use them daily. Specifically, they should be used at night because some types are deactivated by light and air. It's important to start slowly and allow your skin time to adjust. Using too much too quickly can cause redness, dryness, and irritation.
Perform the nighttime skincare routine as directed above. After applying retinol to your skin (while it's dry) allow it to sit for 10-20 minutes. Mist your face with water or a facial spray, and then apply your hyaluronic acid. (HA serums are most effective when they're applied to damp skin.)
Regardless of your skin type or which product you use first, a layer of moisturizer should always be applied after retinoids.
If you're new to retinoids or prone to irritation — even if you're not prone to irritation — you may find that your skin can be reactive when the vitamin A derivative is introduced to your skin-care routine. Both Dr. Chang and Dr. Farhang recommend initially using a small amount of a retinol product every other night.
Slather it on at night and emerge with glowier, smoother skin in the morning thanks to its magical ability to treat acne, prevent dullness, promote plump, firm skin, and minimize fine lines and wrinkles.
You should use retinol at night, as it can break down in light and make your skin more prone to sunburn. In the morning, use BHA to get rid of any dead skin cells caused by your nighttime retinol application.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out skin and cause further irritation if your skincare routine already includes retinol. As for benzoyl peroxide and retinol, they cancel each other out.
The best product you can use in conjunction with retinol, according to Dr. Zeichner, is a moisturizer, which can help hydrate skin and reduce the risk of irritation from retinol. “Some people even prefer to mix their retinol with a moisturizing cream to dilute it out,” he says.
The truth: You can use vitamin C with retinol and retinoids. Get them as separate products so you can tailor the concentration of each and use them at the right time of day. Although vitamin C can be used day or night, it is ideal for daytime use, while retinol and retinoids should be applied at night.
What Are the Benefits of Combining the Two? Good news: Retinol and hyaluronic acid actually have a synergistic effect. “They can be combined so that the benefits of retinol can be achieved more easily with concomitant use of hyaluronic acid, which helps to prevent retinol irritation,” says Hartman.
Should you use retinol under your eyes? Yes, definitely. While it is true that retinol – a form of vitamin A – is a powerful ingredient and the skin under your eyes is delicate, there's no reason why you should miss out on the amazing benefits of retinol.
Apply topical retinoids
Retinoids, which are topical vitamin A-based derivatives, may help reduce fine lines and wrinkles by increasing collagen production. If you use retinoids on your face, extend the treatment area to your neck and chest at night. Retinoid products are available by prescription or over the counter.
If any side effects or irritation occur, it's best to space out applications until your skin adjusts. This might mean applying a retinol serum every third evening, and gradually increasing application to every other night and then every night as the skin's tolerance increases.
Retinol (leave to absorb for 10-20 minutes)
Retinol is also an ingredient that should be left to absorb sufficiently into the skin before following up with another product. “It is important to leave a 10-20 minute wait time before applying the next product.
No matter which form you choose to incorporate your hyaluronic acid, it should be close to the final step in your routine. If you are using it in serum form, you'll apply it immediately after your retinol. If it is part of your moisturizer, it will be your last step.
Spread it over your face, avoiding your eyes and mouth. Afterward, you can apply any brightening products, followed by serums or night creams. “Because retinols can be drying, it's ideal to follow with an effective moisturizer to help keep skin hydrated and [the] skin's barrier protected,” Gabriel notes.
Niacinamide and retinol can be combined in one product, which may be easier and more convenient. But they're also available as separate products. If you're using these ingredients in separate products, it's recommended to apply niacinamide first and to then follow with retinol.
Using niacinamide before retinol works well. So does combining them into one product. A 2016 study found that a product containing retinol, niacinamide, hexylresorcinol, and resveratrol improved fine lines, sallowness, wrinkling, hyperpigmentation, and skin tone.
A combination of retinoids and humectants such as niacinamide, panthenol, glycerin, and hyaluronic acid can help slow down TEWLs during application of retinoid. Hyaluronic Acid is an excellent ingredient to alleviate some of these concerns.
Products With Active Ingredients
Keeping your retinol moisturizer or benzoyl peroxide acne spot treatment in a dark and cool environment like the fridge will slow down the degradation of the active ingredient.
