At night, apply a pea-sized amount of your retinol product ideally 30 minutes after you've washed your face. "Start three times a week (Monday, Wednesday, and Friday) as dryness and peeling can be expected for four to six weeks," suggests Dr. Marchbein.
Retinol should always be applied at night.
It's especially sensitive to light, which is why it's kept in dark packaging or packaging that doesn't let any light through. In order to avoid unnecessary sun damage, only ever apply retinol before you go to bed.
If it's a non-prescription retinol, apply it according to what type of product it is—a retinol moisturizer will act as the moisturizer step of your routine, while a retinol serum will act as the serum step.
To apply a serum with retinol correctly, Smooth it onto clean skin before your moisturizer. Your serum will have a thinner consistency than your moisturizer, which is what determines the application order.
To help your retinoid work better, some dermatologists recommend applying it directly after cleansing before any other treatment serum or moisturizer.
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.
And now another rule to keep in mind: Many prescription-strength retinoids suggest users wait upwards of 20 minutes post-cleansing before putting retinol on their skin and 20 more minutes before putting anything else on, according to Reddit.
If you're using these ingredients in separate products, it's recommended to apply niacinamide first and to then follow with retinol. Applying niacinamide first can help protect your skin from the effects of retinol.
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.
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.
After cleansing, tap your acid-based toner over clean, dry skin every other night (or if you plan to use a retinol at night, apply your acid-based toner every other morning), then wait a full five minutes—or, at the very least, until it dries—before applying anything else, or you'll accidentally neutralize the acids ...
To use retinol before a moisturizer, wash the face and when completely dry, apply a pea-size amount of retinol. Retinol should not be used on damp skin because the skin will absorb more than required and cause irritation. Finish with a moisturizer to hydrate the skin and reduce the risk of irritation.
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.
When it comes to mixing all three together, the best order to apply them is by starting with retinol, followed by hyaluronic acid, and finally niacinamide. By applying retinol first onto a fully cleansed skin the ingredient can penetrate into the lower layers.
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.
Niacinamide is one of those skincare ingredients that just seems to do everything! It's anti-aging, reduces pigmentation, fights acne, reduces facial redness, and hydrates skin. The latter of which particularly makes it an ideal companion to retinol.
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.
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.
Retinoids and serums can be used together, especially if the serum is soothing or hydrating. Be careful using very aggressive face oil serums with retinoids.

There are several skincare ingredients you can layer with retinol. Hydrating ingredients, such as hyaluronic acid, niacinamide, squalene, and vitamin E are considered the best at neutralising the irritation associated with retinol.
For retinol newbies, he recommends waiting 10 minutes after washing and drying your face before applying the product. What you do want to do is always wear SPF—especially when starting a retinol routine. This is because retinol makes your skin more sensitive to the sun's harmful UV rays.
"I recommend using both a vitamin C serum and retinoid daily, since they serve different purposes and work synergistically to help your skin look its best." Since vitamin C protects your skin from free radical damage caused by the sun and pollution, your serum should be applied in the morning, whereas retinoids build ...
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.
