The Downsides Of Using Vitamin C At Night

Vitamin C in high concentrations is very acidic which means it could potentially cause irritation or redness if left on too long. The only time that it is recommended to use this product at night is if you suffer from acne or hyper-pigmentation. Using vitamin C serum overnight may be a little too harsh for people who have sensitive skin and can cause irritation, which will trigger redness and flaking. It also contains pure retinol, so it increases the speed of aging and therefore speeds up existing wrinkles and fine lines while making your skin more susceptible to dryness.

Should You Moisturize Your Skin Before Applying Vitamin C Serum

Apply your vitamin C serum first before moisturizing. From thin to thickalways follow this rule of thumb in your skincare routine.

Serums are made to be a thin layer so that they can penetrate deeply into the skin with ease. Apply your vitamin C serum, then seal in the hydration with your moisturizer.

What Are The Benefits Of Using A Vitamin C Serum

How to Apply Vitamin C Serum for Face, Using The Best Vitamin C Serum

While there are many vitamin C serum benefits, we focused on three that we believe are most impressive. Each has been backed by scientific research, so you can be confident youre spending your money wisely.


If youre one of the many people who deal with hyperpigmentation, vitamin C may be able to help. Although it takes weeks of consistent use to see a difference, applying topical vitamin C can help slowly fade dark spots and redness, leaving you with an even skin tone.

Vitamin C can help with discoloration because it inhibits the production of an enzyme called tyrosinase, which is crucial in melanin production. Dark spots naturally become less and less visible with less melanin being produced.


As we age, our bodys production of collagen naturally starts to slow down. Eventually, as our collagen stores get lower and lower, we notice an increase in the visibility of fine lines, wrinkles and other skin aging concerns.

Because of the role that vitamin C plays in collagen synthesis, one of the top vitamin C serum benefits is that it can promote collagen production. Increasing the amount of collagen in the skin is one of the best anti-aging techniques, as it can reduce the appearance of fine lines and wrinkles and firm the skin.

What Are The Benefits Of Using Retinol

Retinol supports our bodys cellular turnover .

How is this beneficial?

It rids old, dead skin cells, which cause the skin to look dull, and replaces them with new, healthy cells, reinvigorating the skin and making it appear radiant.

Remember, our skin cells go through a lot with the pollution and dirt they face every day, which makes the skin dry, flaky, dull, and generally undesirable and prescribed retin A or non-prescription retinol can help.

Should You Use Vitamin C With Retinol

Theres been a lot of uncertainty around using retinol and vitamin C. This hesitation is due to their differing pH levels.

You see, both retinol and vitamin C require a specific pH level to get absorbed into the skin. For vitamin C, its 0 to about 3.5, while retinol requires a higher pH level of 5.5 to 6. And mixing vitamin C and retinol results in an increase in the vitamin Cs pH and a decline in the retinols pH, which is why many believe that the two ingredients render each other ineffective.

However, contrary to this popular belief, the two work brilliantly together. The secret lies in applying the two in succession. Apply vitamin C serum and wait a minimum of 30 minutes to give it time to get absorbed before using retinol.

Its common, though, to experience skin irritation, but you can prevent such a reaction by using them at different times of the day. Ideally, you can use your vitamin C serum in the morning and the retinol at night.

Vitamin C stabilizes retinol, making it more effective. And when applied correctly in the right succession, the two ingredients form a barrier which protects the skin from the adverse effects of the environment that cause skin damage and speed up aging.

Different Forms Of Vitamin C In Skincare

Its helpful to note that not all forms of vitamin C are created equally. As weve learned already, the pure form of vitamin C is called L-ascorbic acid, or ascorbic acid. You can find many safe, quality skincare products that contain the ideal amount of vitamin C in this form.

But other formulations contain vitamin C that can still be just as effective, even if the ingredients dont contain vitamin Cs purest form. Other forms of vitamin C that show up in skincare ingredients lists include:

  • Sodium ascorbyl phosphate
  • Retinyl ascorbate

Is There Anything You Cant Use With Vitamin C

A skin care routine doesnt consist of a single product with a single main ingredient. To create a quality routine that supports your skin and tackles your specific issues, you need a combination of products, such as a cleanser and hydrating moisturizer, with other targeted products filling it in .

Unfortunately, not all of the ingredients used in those products play well together. If youre planning to add vitamin C to your skin care routine, its also essential to know what ingredients you should avoid using.

Luckily, if you know how to incorporate them safely, there arent any off-limits ingredients. The main concern is that vitamin C can make the skin sensitive, especially if youre new to the ingredient or using it in a high concentration.

This irritation is more pronounced in people with sensitive skin or using hydroxy acids or retinol. If youre prone to sensitivity, use your vitamin C serum only once or twice a week and increase the frequency as your skin adjusts.

When using a vitamin C serum, it should always be applied after thoroughly cleansing your skin but before applying your moisturizer or sunscreen. Let each of your skin care products dry completely before using the next one to give them enough time to absorb.

Use The Right Concentration Vitamin C For Your Skin Type And Concerns

Different products may contain a wide variety of concentrations of vitamin C. In general, they range from below 5% all the way up to 30%, Dr. Hogan says, and this ingredient can have different effects at those concentrations.

Those with dry or sensitive skin probably want to stick with lower concentrations, around 5%, which are less likely to be irritating. But those with more oily skin or with more extensive pigmentation issues to tackle can handle higher concentrations. However, as SELF explained previously, the effects begin to plateau after 20%, so theres usually no need to go higher than that.
