Many gentle serums, such as a hydrating Hyaluronic Acid Serum, barrier-boosting niacinamide serum or soothing, Anti-Redness Serum are effective applied morning and/or night.
A hydrating serum is a great option for morning to ensure the skin is moisturized.
Anti-pigmentation and antioxidant serums work best when applied in the morning. This helps protect your skin against environmental assaults and free radical production produced by light, including UV and high energy visible light. Anti-aging serums are often best suited for nighttime application.
"Because vitamin C serum helps protect your skin from free radicals, most dermatologists have recommended applying it in the morning to prevent damage during the day," says Joshua Zeichner, the director of cosmetic and clinical research at Mount Sinai Hospital in New York City.
Limit to Two Serums Per Routine
We recommend you use no more than two serums per routine. Again, alternating skin care items is a strategy here. If you have many serums that you like, use one to two in your morning routine and two different serums in the evening.
While there is no limit to how many serums you can add to your regimen, esthetician Enrique Ramirez, founder of Face to Face NYC, suggests stopping at three. Piling on more products than that is not only time-consuming, it also reduces the chances of each ingredient getting properly absorbed by your skin.
Yes! Hyaluronic Acid can be combined with Vitamin C products or applied separately as the second layer of defense.
How often can you use it? It's always best to follow specific product instructions and to start off slowly. Generally, though, you can safely use hyaluronic acid both morning and night.
If you are applying a Vitamin C serum and hyaluronic acid separately, it's suggested that you apply the Vitamin C first, and then add the hyaluronic acid afterward in order to help fortify the skin barrier and lock in the moisture.
How and when do you use niacinamide? Niacinamide can be used morning and night. Because it plays well with other skincare ingredients (even potentially tricky actives such as exfoliating acids and vitamin C) it will sit happily alongside anything else you're using.
Niacinamide With Vitamin C Are a Winning Combination
This means that you're safe to use both niacinamide and vitamin C, either together in the same product, or combined from different products that you layer one over the other.
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.
If you're wondering when to apply a vitamin C serum, the answer is both morning and night, after cleansing and toning. One study even recommends applying a vitamin C serum every eight hours, or twice daily for the pinnacle of protection.
Although many products containing salicylic acid recommend that you apply them in the morning and night, you should always be cautious when using an ingredient like this in the day as salicylic acid can make the skin more sensitive to the sun.
No matter which form you choose to incorporate your hyaluronic acid, it should be close to the final step in your routine. If you are using it in serum form, you'll apply it immediately after your retinol. If it is part of your moisturizer, it will be your last step.
Find a serum that claims to do just what you need it to. - Secondly, consider your skin type. If you have oily and acne-prone skin, select a face serum with salicylic acid and retinols, as well as rosehip seed oil. For mature and dry skins, try something with hyaluronic acid and Vitamin C.
Hyaluronic acid and Niacinamide are a great pair as both are water-based treatments. When used together, always go with applying hyaluronic acid first, followed by Niacinamide. By following this, you would be able to attract plenty of hydration first.
Use your vitamin C serum first, and let it dry.
Then "Let vitamin C completely dry prior to placing niacinamide," says Lamm. That way, the ascorbic acid has a chance to settle into the skin, and there's a smaller chance of combining the two actives.
“Hyaluronic acid plays well with most ingredients, while caution must be taken when using retinol in combination with alpha hydroxy and beta hydroxy acids, benzoyl peroxide, and some types of vitamin C.”
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.
It's an ingredient found in a number of moisturizing skin-care products, as well as certain foods and supplements like multivitamins. Can you use niacinamide every day? Yes. In fact, you can use niacinamide-containing topical products in the morning and night because it's generally a gentle ingredient.
As for whether you should apply glycolic acid morning or night, we recommend applying it as part of your evening skincare routine. Glycolic acid can cause “photosensitivity,” which means it makes your skin more sensitive to the sun's UV rays, upping your chances of a sunburn or skin damage.
While the two ingredients are similar, they also have their differences. "Because it's a mild acid, vitamin C also gives you more of an exfoliating and brightening effect than niacinamide," says Dr. Lee. "Niacinamide has a greater impact in terms of hydrating the skin."
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.
So, can you use niacinamide and vitamin C together? The short answer to your question: yes, you can.
