Vitamin C inhibits tyrosinase, an enzyme responsible for melanin production, while Niacinamide blocks pigment from transferring within our skin cells. Combining these two ingredients often delivers better results than simply using one or the other, creating true skincare synergy.
Niacinamide can concurrently rebuild healthy skin cells while also protecting them from damage caused by ultraviolet rays. Treats hyperpigmentation. Some research has found 5 percent niacinamide concentrations can be helpful in lightening dark spots.
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.
Niacinamide serum will help you deal with the signs of aging, lessen the fine lines, and reduce hyperpigmentation on your skin. While Vitamin C will protect your skin from UV rays, increase the collagen production and clear out acne and acne scars.
Might Lighten Dark Spots
Vitamin C-based skin care products may lighten patches that are darker than the rest of your skin, called hyperpigmentation. In one study, vitamin C applied to the skin for 16 weeks significantly cut down on these spots.
Now that you know the benefits of each, you're probably asking “can you use niacinamide with vitamin C?” In short, the answer is yes. In fact, the many vitamin C and niacinamide skin benefits complement each other and create a powerful combination that targets fine lines.
But when it comes to which ingredient should go on your skin first, it doesn't really matter. Your best bet is to decide based on the formula of the particular products you're using, applying them from thinnest to thickest, advises Arch.
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.
While some niacinamide-containing products start to show initial benefits in two weeks, most results will show in four weeks or more. "You have to remember that it doesn't take two days for spots to form so you can't expect them to be removed in two days either," explains Engelman.

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.
But overall, stick to using water-based products and serums together. 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.
Don't Mix: Niacinamide and vitamin C. Although they're both antioxidants, vitamin C is one ingredient that's not compatible with niacinamide. "Both are very common antioxidants used in a variety of skincare products, but they should not be used one right after the other," says Dr.
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.
Vitamin C + vitamin E
Vitamin E is no slouch as a skin care ingredient itself, but when paired with vitamin C, the Linus Pauling Institute at Oregon State University states that the combination is more “effective in preventing photodamage than either vitamin alone.”
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.
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.
What It Does: This potent antioxidant interferes with the production of pigment in the skin, fading dark spots. When You'll See Results: Once you add vitamin C to your skincare regimen, you may start seeing noticeable improvements in three weeks. It can help significantly fade hyperpigmentation in about two months.
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. The result is that retinol and other retinoids may help improve skin's texture while helping to minimize the look of fine lines.
Expect that your skin tone or dark spots will lighten over time. How long this takes will vary with each person but in general, you should notice a visible difference after 2-3 weeks, and a significant difference after 8-12 weeks.
Researchers found Niacinamide is an important ingredient in skin lightening, which works to stop the transfer of melanin pigment (responsible for the darkening of the skin) to skin cells (keratinocyte). Niacinamide decreases hyperpigmentation and lightens skin gradually after using it for a long duration.
There's certainly no law against using vitamin C products in the evening, but, again, you may get the most benefit from using them in the morning. “In general, vitamin C products should be applied in the morning before heading out for the day, when UV radiation is at its highest,” Dr. Hogan says.
Vitamin C is used for its anti-ageing benefits as it boosts collagen, improves elasticity and repairs damaged cells. Using it before bed is safer and has far more beauty benefits and thus, we totally recommend you to use it in the night, before hitting the sack.
