If you do choose to use an exfoliant with tretinoin, avoid using it too frequently. A good strategy is to begin by exfoliating once per week, then increase to twice per week at most if your skin is smooth, healthy and irritation-free after a few weeks of tretinoin usage. Finally, make sure you avoid over-exfoliating.
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.
When first starting a retinol regimen, or if your skin is sensitive, it's best not to combine retinol with other potentially irritating ingredients, such as alpha or beta hydroxy acids or physical exfoliants and scrubs. The best product you can use in conjunction with retinol, according to Dr.
Since Retinols and the like tend to be used at night, an a.m. scrub might be better for you. But, regardless of when you exfoliate, both derms agree on the type of exfoliant you should use: "[It] should always be gentle, with vibrating or ultrasonic brushes, super-fine scrubs, etc.," Dr. Grossman says.
Most experts advise that you exfoliate two to three times per week — as long as your skin can handle it. Chemical exfoliants tend to be fine to use more regularly. Physical methods, on the other hand, may be too abrasive to use multiple times a week.
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.

You'll likely want to use retinol once or twice per week initially and work up to using it more than that. The reason: Retinol can initially be drying, especially if you have sensitive skin, so it's a good idea to give your skin some time to adjust to the change in your routine.
If you have time, you can use hydroxy acids and retinol sequentially. After applying an AHA or BHA product, wait for 30 minutes to allow your skin's pH to return to normal, and then apply the retinol product.
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.
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.
If you use a scrub or chemical exfoliator, apply the product gently using small, circular motions. Do this for about 30 seconds, and then rinse off with lukewarm — not hot — water. If you use a brush or sponge, use short light strokes. Never exfoliate if you have open cuts or wounds or if your skin is sunburned.
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.
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.
A formula with retinol, like the L'Oréal Paris Revitalift Triple Power Eye Treatment, should be applied after your serums and before moisturizer due to its consistency.
“If you're overusing your retinol, or if you're using a retinol that's too strong for you, it can lead to peeling, irritation, and excessive dryness, which may have led to retinol's association with skin thinning,” she says.
Retinol is a well-known ingredient in pro-aging creams, gels, and serums. What many people don't know is that it can also be used to treat acne and acne-scarred skin. It works on both the surface and middle layers of the skin to unclog pores, smooth scars, and improve tone and texture.
DON'T rinse off a chemical exfoliant
After exfoliating, don't wash it off right away - the active ingredients take time to absorb into your skin and work their magic! Leave your exfoliant on for about 15-30 minutes to ensure the ingredients dissolve and remove all dead skin cells.
When it comes to morning versus night exfoliation, you're going to reap the best benefits from exfoliating in the morning time. This is due to the oils your skin produces overnight. You'll be able to more smoothly remove all impurities, dead skin, and oils, when you exfoliate in the morning, rather than at night.
Lack of exfoliation leads to build up of dead skin cells, and could result into dry, dull, patchy, flaky skin, clogged pores, with uneven skin tone.
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.
In the world of skincare, prescription-grade Retin-A is like a magic cream for your face. When applied in the evening, Retin-A increases cell turnover and exfoliation so effectively that the side effect of exfoliation, flaking skin, is often the reason people give for stopping use of Retin-A.
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.)
