Retinol is best applied at night since it can increase your skin's sensitivity to the sun. When you do go outside, be sure to use sunscreen to protect your face. It's worth noting that you don't need to use retinol on a daily basis for it to effectively treat your acne. Even two to three times per week might be enough.
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.
When To Apply a Moisturizer With Retinol
Cleanse, apply any serums in your routine, then layer your moisturizer. In this case, you don't have separate retinol and moisturizer steps; you're knocking out two steps in one.
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.
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.
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.
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.
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.) Finally, follow your HA serum with a moisturizer right away.
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.
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.
You should use hyaluronic acid after retinol. And to maximise the benefits, you should use retinol first and then wait at least 30 minutes before applying hyaluronic acid.
Is it safe to use retinol every day? For most people, yes — once your skin is used to it, that is. That said, there are some people who may not want to use it frequently or at all.
“Start with a very small, pea-sized amount on one night, and then wait a few days to evaluate your tolerance.” If you don't get a reaction, Carroll recommends trying it again. However, if the product makes your skin red and flaky, she suggests mixing the retinol formula with your moisturizer.
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.
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.

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.
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.
The problem is, retinol can be irritating when applied straight to the lips (so keep your prescription-strength cream off your mouth for the time being). But Verso's formula contains a gentle derivative, called retinol 8, which can reduce the appearance of fine lines around the mouth overtime.
Engelman agrees: "Retinol is the most potent ingredient that helps build collagen and elastin, which leads to tighter, smoother skin."This mixture has the added bonus of hyaluronic acid, which "can smooth, firm, and tighten the appearance of the skin," Dr. Bowe says.
Use Exfoliants Sparingly After the Adjustment Period
After two to six weeks of using tretinoin, it's usually okay to start using an exfoliant. However, it's best to use exfoliating products as sparingly as possible while using tretinoin to avoid potentially irritating your skin.
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.
Applying retinol is a long-term treatment which promotes fresh skin, fewer blemishes and reduction in acne breakouts. Whereas in the short term, it can lead to acne breakouts, skin peeling, dryness, and a range of other frustrating temporary outcomes. The purge phase usually lasts for two to six weeks.
