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.
A combination of retinoids and humectants such as niacinamide, panthenol, glycerin, and hyaluronic acid can help slow down TEWLs during application of retinoid. Hyaluronic Acid is an excellent ingredient to alleviate some of these concerns.
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. As for benzoyl peroxide and retinol, they cancel each other out.
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.
It's perfectly safe and okay to use hyaluronic acid and retinol together. Using skin care products that contain these ingredients together shouldn't cause any interactions or side effects. Hyaluronic acid and retinol are one of the most popular skin care combinations.
Hyaluronic Acid and Niacinamide
These water-based treatments are a great pair and are made for all skin types — especially babes with dry, acne-prone skin. You'll find niacinamide, a form of vitamin B3, in my Rewind Retinol Serum. Use hyaluronic acid first, followed by my retinol for the best results.
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.
Is it a good idea to combine Vitamin C, Retinol and Hyaluronic Acid in a skincare routine? Yes. These ingredients work well when used individually and even better when paired together.
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.
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.
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.
It's best to apply Vitamin C before Retinol, as Vitamin C has a lower pH than Retinol. Once your skin absorbs the Vitamin C serum, your skin will return to its regular pH levels after 30 minutes or so. (You want your skin to return to its normal pH levels so vitamin C doesn't lower the pH of retinol.)
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.
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.
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.
Layering products correctly is important if you want your products to work. If you place one product on your skin, like a serum, and follow up with another product whose molecules are smaller than the first, like a toner, then the second product cannot penetrate the first layer.
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.
Here's where things get hairy: Older research has shown that mixing vitamin C—specifically the unstable ascorbic acid—with niacinamide can convert it to the compound niacin, which can cause flushing (think blotchy, inflamed skin).
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.
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 ...
Can I use niacinamide with hyaluronic acid and vitamin C? The short answer is yes, it is known that you can use all three of these ingredients together safely and effectively. How you use them is up to you, you can team niacinamide with hyaluronic acid, or vitamin C and hyaluronic acid.
When layering these powerful ingredients applying vitamin C first and leaving about 15 minutes in between applying your niacinamide product will give the skin enough time to absorb and remain comfortable before using niacinamide to lock moisture into the skin.
Now that we know it's a perfectly safe combination, feel free to mix niacinamide and vitamin C to your heart's content. However, if you still feel nervous about combining the two ingredients on your sensitive skin, you can always use niacinamide in the morning and vitamin C at night, or even alternate days.
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.
