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.
Regardless of your skin type or which product you use first, a layer of moisturizer should always be applied after retinoids.
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.
Owing to its potency, retinol products can make the skin more sensitive to the sun. Hence, always apply it at night. “In the morning, make sure you follow up your skincare routine with a face wash, vitamin C serum, under eye cream, moisturiser and then a sunscreen,” advises Dr. Mittal Gupta.
Should I use Hyaluronic Acid before or after Retinol? 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.
Keep reading to learn the exact skin care routine steps for applying retinol, but in most skin regimens, serums will be step 3 at night, moisturizers are step 4 and retinol goes after the serum and the moisturizer.
Whether you're using retinol or not, the final component of any skin care routine should always be a moisturizer.
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.
"It is best to avoid other drying agents when using retinoids such as toners, astringents, and medicated cleansers. These products cause further irritation," mentioned Dr. Lipner. Instead, consider piling on rich, creamy moisturizers to counteract any dryness that may occur.
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.
For sensitive skin types, some experts even recommend the “sandwich method” when using retinol. First, apply a light layer of a humectant-filled moisturizer like Dew Point. Next, smooth on your retinol. Finally, apply a second, thicker layer of the same moisturizer to seal everything in.
"Studies have shown that layering topical retinoids over moisturizers minimizes skin irritation without interfering with how well they work in the skin," says Joshua Zeichner, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City.
While prescription-strength retinoids may have an effect in a matter of weeks, it can take up to 6 months for OTC retinols to produce the same results. You may notice a difference in conditions like acne after 12 weeks, but sun damage and signs of aging can take much, much longer to improve.
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.
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.
So if you start using retinol every day out of the gate, you can end up with some painful inflammation and a damaged skin barrier, negating any potential positives. One way to avoid that irritation is to start slow, explains Ranella Hirsch, MD, a board-certified dermatologist in Boston.
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.
Mix With Peptides
Mariwalla says it's a great idea to use both a retinoid- and peptide-based night cream at bedtime. "You get the collagen-building effects of the retinoid, but it also works to improve the penetration of the peptide cream, which can help improve skin's firmness," she explains.
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.
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.
If you're determined to use vitamin C and retinol together in the same routine, you'll need to make sure to put enough time between them. It's also essential to apply your vitamin C first because it has the lower pH of the two ingredients.
First, vitamin C works to help improve the look of dark spots, fine lines, wrinkles and sagging skin. Then, retinol steps in to help improve skin's elasticity.
