Adding a vitamin C serum to your skincare routine sounds simple, but a few questions often come up. Should you apply it before or after moisturizer? How many drops should you use? And is it better to apply it in the morning or at night?
If you've recently added a face serum to your skincare routine, knowing the right application steps can help you use it consistently.
Here's how to use vitamin C serum: apply 3–5 drops to your clean, dry face and neck, massage gently until absorbed, and follow with moisturizer. During the day, finish with sunscreen. The serum can be used in both morning and nighttime skincare routines.
How to Use The Derma Co 10% Vitamin C Serum Step by Step
Step 1: Cleanse Your Face
Always begin with a clean face. Use a gentle cleanser to remove dirt, sweat, excess oil, and any leftover skincare products.
Rinse with lukewarm water and pat your face dry using a soft towel. Avoid rubbing aggressively, especially if your skin is sensitive.
Starting with clean skin makes it easier to apply the serum evenly.
Step 2: Take 3–5 Drops of Vitamin C Serum
Take 3–5 drops of The Derma Co 10% Vitamin C Face Serum onto clean fingertips or your palm.
You don't need to fill the entire dropper or apply multiple layers. The recommended amount is generally sufficient for your face and neck.
Using additional product won't necessarily improve the results and may leave your skin feeling sticky.
Step 3: Apply the Serum Evenly
Gently spread the serum across your forehead, cheeks, chin, and neck.
Using your fingertips, massage in light upward circular motions until absorbed. Avoid the eye area and any broken or irritated skin.
There's no need to rub vigorously. Gentle application is enough to distribute the serum.
Step 4: Follow with a Moisturizer
Once your serum has absorbed, apply a moisturizer suitable for your skin type.
Although the serum contains hyaluronic acid, following it with moisturizer helps maintain hydration.
If you have oily skin, a lightweight moisturizer may feel more comfortable. If your skin tends to feel dry, choose a more nourishing formula.
Step 5: Apply Sunscreen During the Day
If you're applying the serum in the morning, complete your skincare routine with broad-spectrum sunscreen of SPF 30 or higher.
Sunscreen is especially important when you're concerned about dark spots and pigmentation because UV exposure can contribute to uneven skin tone.
Remember, vitamin C provides antioxidant benefits, but it doesn't replace sunscreen.
When Should You Apply 10% Vitamin C Serum: Morning or Night?
You can use The Derma Co 10% Vitamin C Face Serum in both your morning and nighttime skincare routines.
The brand recommends applying it twice daily. However, if you're introducing vitamin C into your routine for the first time, consider starting once a day and gradually increasing usage.
Morning Routine with Vitamin C Serum
Using vitamin C in the morning is an easy way to include antioxidant care in your daily routine.
Follow these steps:
-
Face Wash: Cleanse your face to remove excess oil and impurities.
-
Vitamin C Serum: Apply 3–5 drops and massage gently until absorbed.
-
Moisturizer: Apply a moisturizer suitable for your skin type.
-
Sunscreen: Finish with broad-spectrum SPF 30 or higher.
You don't need an elaborate routine. Keeping these four steps consistent is more practical than frequently switching products.
Night Routine with Vitamin C Serum
The serum can also be applied before bedtime.
Follow these steps:
-
Face Wash: Cleanse your face to remove sunscreen, dirt, and accumulated oil.
-
Vitamin C Serum: Take 3–5 drops and spread evenly across your face and neck.
-
Moisturizer: Complete your routine with a moisturizer.
If your nighttime routine already includes retinol or exfoliating acids, introduce vitamin C gradually. Using several active ingredients together may cause irritation, particularly if your skin isn't accustomed to them.
How Often Should You Use The Derma Co 10% Vitamin C Serum?
According to the product instructions, the serum can be applied twice daily.
However, your skin's tolerance matters.
For beginners, applying the serum once daily or every other day can be a sensible starting point. Once your skin feels comfortable, you can gradually increase frequency.
Avoid applying extra layers in the hope of getting faster results. A small amount used consistently is generally more practical than excessive application.
If you experience persistent redness, burning, or itching, discontinue use.
Should You Patch Test Before Applying Vitamin C Serum?
Yes. Patch testing is a sensible precaution before introducing any new skincare product.
Apply a small quantity to a clean area, such as your inner forearm, and observe for irritation over the following 24–48 hours.
The Derma Co 10% Vitamin C Face Serum has also undergone dermatological testing. Its published patch-test certificate reports that the tested formulation was found to be non-irritant under Protocol No. C3B04977.
Along with patch testing, the serum has undergone additional laboratory checks. Its NABL laboratory report covers quality testing for the specified batch, while the clinical testing report provides details of the formulation's permeation study. These reports offer more information about the testing carried out on the serum.
Common Mistakes to Avoid When Applying Vitamin C Serum
Even a simple serum routine can become less comfortable if you overlook a few basic steps.
-
Applying too much: Stick to the recommended 3–5 drops.
-
Skipping moisturizer: Follow the serum with moisturizer to support skin hydration.
-
Forgetting sunscreen: Always include sunscreen in your morning routine.
-
Using too many actives together: Introduce new skincare ingredients gradually.
-
Ignoring irritation: Stop using the serum if it causes significant or persistent discomfort.
-
Incorrect storage: Keep the bottle tightly closed and away from direct sunlight and excessive heat.
