We recommend that beauty lovers use our Vitamin C Serum after cleansing, exfoliating, masking, and/or toning — but always before moisturizing. All you have to do is apply a couple pumps of serum to clean fingers, and gently press the product evenly over damp skin.
Step 3: Apply Vitamin C serum. Pat any excess product onto the top of your hands, neck, and décolletage. Step 4: Apply a moisturizer (Yes, your moisturizer should come after your Vitamin C serum — remember the “thinnest to thickest” rule.)
Vitamin C serum is typically applied once or twice per day. A good rule of thumb is to cleanse, tone, apply vitamin C serum, and then moisturize. It can be safely used with other active ingredients, although using alongside niacinamide may make vitamin C less effective.
We all have different skin needs and routines, but as a general rule, we recommend incorporating vitamin C into your skincare regime every—or every other—morning. We specify morning, because the antioxidant helps to protect from things like pollution and UV light, which you're typically exposed to throughout the day.

Dr Khan explains: “With vitamin C, you want to get the most out of the product by not diluting it. A couple of minutes should be an adequate time for the product to dry down before you go in with your next step.”
Since serums contain the active ingredients that you want to penetrate as deeply as possible into your skin, you should always apply a serum directly to your skin after cleansing or toning and before your moisturizer and sunscreen. Don't put your serum on after you moisturize.
A thick moisturizer with hyaluronic acid would be applied after a vitamin C serum, but a hyaluronic acid serum will come before a face cream with vitamin C in its formula. In the case that you have two separate serums, it still comes down to thickness. Apply whichever is thinner first.
AHAs and BHAs, such as glycolic, salicylic, and lactic acids should never be used with Vitamin C. Vitamin C is an acid, too, and is unstable, so the pH balance will be thrown off by layering these ingredients together and might as well be useless.
Yes, you could use niacinamide in the morning and vitamin C at night. Both ingredients are highly effective and are able to deliver impressive results whenever they are applied to the skin.
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.
“I recommend using vitamin C products twice daily for maximum benefits,” Dr. Chang said. “If used in serum or essence forms, it should be applied after cleansing and before your thicker moisturizers and creams.”
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.
Many people wonder when the best time is to use their Vitamin C products. While some associate Vitamin C with daytime, others believe nights and evenings are best to use their Vitamin C-infused products. The truth is, Vitamin C can work effectively in the days or evenings.
Both vitamin C and niacinamide increase the natural production of ceramides in your skin which helps to strengthen your skin barrier, keep your skin hydrated, and reduce irritation. However, niacinamide is probably the better option for sensitive skin as it's usually gentler than vitamin C.
Several blogs, and even some beauty magazine articles, state that while the two ingredients are great on their own, combining them creates a two-fold problem: One, it neutralizes the effectiveness of both ingredients, and two, it might create a substance (nicotinic acid) that leads to skin redness.
You can absolutely use vitamin C and niacinamide together, Singh goes on to emphasize. That said, if you ever have any doubts as to whether it's safe to mix two skin care ingredients, a dermatologist can always offer advice. Your skin is affected by more than what you put on it.
When do I use Vitamin C in my routine? Vitamin C absorbs into skin most effectively after cleansing. AM: after cleansing, allow to absorb before applying a moisture lotion/SPF. PM: add a dose to your go-to night moisturizer, or layer a Vitamin C serum beneath it for a boost.
Well, the quick answer is yes, you can mix serums with moisturisers. For this, you should follow the same guidelines as when you mix two serums together. Mix a couple of drops of serum in the palm of your hand with the moisturiser of your choice. Then just apply it to your face.
Can you use BHA and vitamin C together? Yes, you can, but only if you use each ingredient properly in your routine.
"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.
Combining the two makes for a great all-in-one skin care step. “Hyaluronic acid and vitamin C are commonly used together because they complement each other to hydrate, protect, and repair aging skin,” says Zeichner.
Can you use vitamin C and hyaluronic acid? Yes, you can! By combing these two ingredients together makes a potent blend of skin reviving duo.
To allow serums to fully absorb, apply and wait 5 minutes before moisturizing. Take note: Well-formulated serums absorb quickly and disappear into your skin. If they leave an oily or sticky residue, they're not doing their job well.
Niacinamide Serum – As most niacinamide serums are water-based, it's best to apply them after cleansing and toning and before oil-based serums or moisturizers. This way, you ensure the highest possible absorption and effectiveness.
