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.
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.
If you are using a low-strength formula, you can start using it once or twice daily. When using moderate and high-strength retinol, it is best to be a little more cautious. We recommend introducing these products to your skincare routine no more than three times per week and monitoring how your skin responds.
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.
Importantly, retinol makes your skin more sensitive to sunlight so be sure to use sunscreen and avoid the sun as much as you can while you use retinol products.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out the skin and cause further irritation if your skincare routine already includes retinol.
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.
Make sure to leave some space in your fridge for your retinol and vitamin C skincare, as these antioxidants can degrade much quicker and become unstable when exposed to heat and sunlight. Storing these products in the fridge keeps the formulas stable and helps with preservation.
"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.
At night we might be using night creams that contain actives such as retinol which are not recommended to be used in the morning so it is essential to wash your face in the morning to remove those residual creams/serum.
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.
There's no problem with using both retinol and vitamin C as part of your skincare routine, dermatologists say. In fact, Shirazi calls this combo a "power couple" when it comes to aging well.
Yes, you can use hyaluronic acid with retinol together and it's perfectly safe to do so. In fact, using hyaluronic acid with retinol has synergistic effect on your skin because they complement each other.
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.
Yes, you can safely put retinol creams on your neck. “Retinol can sometimes cause redness or irritation as a side effect, but it is worth the effort. Fortunately, there are beginner formulations that can get skin acclimated gradually,” Dr. Schlessinger says.
If you stop retinol and do not begin a prescription retinoid, the benefit of preventing acne will go away. The skin cycle of cells being “born” at the base of the skin and moving to the top, dying and desquamating into the surrounding environment takes about 4-6 weeks.
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.
For prescription retinols, you'll typically apply this step onto dry skin before your moisturizer—but always check with your dermatologist. You may be advised to use it after a moisturizer, which buffers the retinol and lessens risk of irritation.
You should always apply retinol in your evening skin care routine, not in the morning skin care routine, because light and sun make retinol ineffective.
Hyaluronic acid is best if they're looking to moisturize dry skin, while retinol works better by encouraging better skin by boosting collagen production. They have several benefits that can work in tandem for better results, though patients need to be careful with the exact formulations they use.
You should always apply retinol at night, after cleansing, and before your nighttime moisturizer. Five minutes is enough to wait for your retinol to sink in before applying moisturizer; you want to layer them, not mix them.
Who should skip retinol? “Retinols can be a beneficial addition for most skin types, but it isn't a one-size-fits-all approach,” Panzica says. Board certified dermatologist Zenovia Gabriel, MD, notes that “people with sensitive skin conditions like rosacea cannot tolerate really strong topicals like retinols.”
