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.
If you want to use both, try exfoliating and using your retinoid on alternating evenings, or exfoliating in the morning and using the retinoid at night. Also, because retinoids increase your sensitivity to the sun, make sure you're always using a broad-spectrum sunscreen with at least 30 SPF, Dr. Lipner says.
Thus, adding exfoliation to this can cause or increase the potential irritation." So, if you use a stronger product, like a Retinol, make sure you space out its application from your exfoliating products. Since Retinols and the like tend to be used at night, an a.m. scrub might be better for you.
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.
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.
Pairing the two ingredients is safe and can make retinol easier to use. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol. Niacinamide and retinol can be combined in one product or used as separate products.
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.
“AHA, BHA, retinol, and benzoyl peroxide can be mixed with moisturizing ingredients like hyaluronic acid, ceramides, and rosehip oil to get effective results — just ensure you are not using retinol as well as AHA or BHA's during the day," says Graf.
At night, apply a natural Retinol serum that works to tighten the skin and mitigate wrinkles, fine lines, and other imperfections while you sleep. Using Vitamin C in the morning and Retinol at night provides your skin with the ultimate brightening and firming treatment.
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.
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 ...
Regardless of your skin type or which product you use first, a layer of moisturizer should always be applied after retinoids.
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.

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.
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.
Generally, it takes a few weeks to see results, but some OTC options may require months of regular use. Most dermatologists said you'll need to use retinol for a few weeks before you see results, but you should see improvements by 12 weeks with most products.
One swap for the holy-grail retinol
Signs it's not working: You're experiencing redness, dryness, peeling, or a burning sensation after using retinol. Why it might not be working: The truth is, retinol can be too active for some people. “It's too strong [for some people],” says Jaliman.
"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 ...
So, should I use vitamin C or retinol for wrinkles? Well, when it comes right down to it, the choice is really in what you're looking to do for your skin. While vitamin C is incredible for the skin because of its ability to help brighten and improve hyperpigmentation, the best active ingredient for wrinkles is retinol.
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.
Retinoid or Retinol and Salicylic Acid
But on its own, each can dry out the skin, so together they should be combined with caution. The risk is overdrying, which can lead to irritation and make the situation worse.
