Vitamin C is one of the most potent antioxidants you can incorporate into your skincare routine. Known for its brightening properties, anti-aging benefits, and ability to combat free radical damage, vitamin C serum has earned a prominent place in many people's skincare regimens. While it’s often recommended to apply vitamin C in the morning for its protective effects against UV rays, nighttime application of vitamin C serum can be just as effective. In fact, your skin’s regenerative process while you sleep makes it an ideal time for treatment.
As a dermatologist, I often advise patients on how to get the most out of their vitamin C serum at night. Here’s your step-by-step guide on how to use vitamin C serum at night correctly, ensuring you wake up with glowing, rejuvenated skin.
1. Choose the Right Vitamin C Serum for Your Skin Type
The first step in getting the most out of your vitamin C serum is choosing the right one for your skin. Not all vitamin C serums are created equal. The stability of vitamin C is a key factor, as it can degrade when exposed to air and light.
- L-ascorbic acid is the most potent form of vitamin C but can be irritating for sensitive skin.
- Sodium ascorbyl phosphate and ascorbyl glucoside are more stable forms and tend to be gentler on sensitive or reactive skin.
- For oily or acne-prone skin, look for serums with a lightweight formula and added salicylic acid or niacinamide to help control oil production.
- If you have dry skin, choose a vitamin C serum that includes hyaluronic acid for added moisture.
Expert Tip:
Always check the packaging for air-tight containers, as exposure to air can cause vitamin C to oxidize and lose its efficacy.
2. Cleanse Your Skin Thoroughly
Before applying your vitamin C serum, it’s essential to cleanse your skin properly to remove dirt, makeup, and excess oils. This ensures that the serum can penetrate the skin effectively.
- Use a gentle cleanser suited to your skin type. If you wear makeup, double cleanse to ensure your skin is thoroughly clean.
- Avoid harsh exfoliants before applying your serum at night, as they can increase irritation, especially if you are using a potent vitamin C serum.
Expert Tip:
Cleanse with lukewarm water—hot water can strip the skin’s natural oils and leave it feeling dry.

3. Apply a Toner (Optional)
After cleansing, you may want to apply a toner to balance your skin’s pH. This step is optional but can help prepare your skin for the serum, especially if you have sensitive skin. Look for a toner that contains calming ingredients like witch hazel or rose water to soothe the skin before the application of vitamin C.
Expert Tip:
If you use an exfoliating toner with AHAs or BHAs, skip it on nights when you are using vitamin C serum to avoid irritation.
4. Apply the Vitamin C Serum
Once your skin is clean and prepped, it’s time to apply the vitamin C serum.
- Dispense a small amount (usually 2–3 drops) of the serum onto your fingertips. You don’t need much; vitamin C serums are concentrated, so a little goes a long way.
- Pat the serum gently into your skin. Avoid rubbing it in, as this can cause irritation or reduce the serum’s effectiveness. Focus on areas with pigmentation, fine lines, or dullness.
- You can also apply the serum to your neck and décolletage for additional benefits.
Expert Tip:
Start slow if you are new to using vitamin C. Apply 2-3 times a week, and gradually increase usage to nightly applications as your skin builds tolerance.
5. Allow the Serum to Absorb
Vitamin C serums are typically lightweight and fast-absorbing. Give it around 1–2 minutes to fully soak into the skin before moving on to the next step in your routine. This will allow the active ingredients to penetrate deeper into your skin, maximizing their effects.
Expert Tip:
If you notice that your serum feels sticky or doesn’t absorb well, it might be because of the formulation. Consider switching to a serum with a different base or one that includes hydrating ingredients like glycerin.
6. Follow with a Moisturizer
After your serum has absorbed, always follow up with a moisturizer to lock in the benefits of the vitamin C and prevent the skin from drying out. Vitamin C can sometimes feel a bit drying, so pairing it with a hydrating moisturizer will ensure your skin remains nourished.
- If you have oily skin, opt for a lightweight, oil-free moisturizer.
- For dry skin, use a rich cream that contains ingredients like ceramides or squalane to replenish moisture.
Expert Tip:
Make sure your moisturizer doesn’t contain any strong exfoliating ingredients (like AHAs) when used alongside vitamin C, as it could lead to irritation.

7. Apply Sunscreen the Next Morning
Vitamin C is a powerful antioxidant, but it can also make your skin more sensitive to the sun. The best way to protect your skin from sun damage the following day is by applying a broad-spectrum sunscreen with an SPF of 30 or higher. Vitamin C serum helps protect the skin from UV-induced damage, but sunscreen is essential for preventing hyperpigmentation and further signs of aging.
Expert Tip:
Make sure your sunscreen is broad-spectrum to protect against both UVA and UVB rays, which can cause premature aging and skin cancer.
8. Consistency is Key
To see the best results with vitamin C serum, consistency is key. You won’t see dramatic results overnight, but with regular use, you should notice a brighter, more even skin tone, reduced pigmentation, and a more youthful appearance. It can take 4–6 weeks of consistent use before you see significant changes in your skin.
Expert Tip:
If you’re concerned about irritation, start by using vitamin C only 2–3 times a week at night, gradually increasing the frequency as your skin builds tolerance.
Final Thoughts
Vitamin C serum is a powerhouse in any skincare routine, especially when used correctly at night. By following the right steps—starting with cleansing, applying a gentle toner, and allowing your serum to absorb fully—you can maximize its benefits and wake up with glowing, rejuvenated skin. With regular use, you’ll notice improved texture, brightness, and a more youthful complexion.
Always pair your nighttime serum routine with the right moisturizer and make sure to protect your skin with sunscreen the next day to get the most out of your vitamin C serum!
