Vitamin C Serum: How to Use It and When You'll See Results

Vitamin C is one of the most popular skincare ingredients, and for good reason. It helps brighten dull skin, improve the look of dark spots and acne marks, and protect against everyday environmental damage. But to get results, you need to use it the right way.

What Does Vitamin C Do for Your Skin?

• Brightens dull, tired-looking skin
• Helps fade the look of dark spots and post-acne marks
• Supports collagen for firmer-looking skin
• Provides antioxidant protection against sun and pollution damage

How to Use Vitamin C Serum: Step by Step

1. Cleanse your face and pat it dry.
2. Apply 3 to 4 drops of vitamin C serum and spread evenly over your face and neck.
3. Wait a minute for it to absorb.
4. Moisturize with a lightweight moisturizer.
5. Finish with sunscreen every morning.

Morning or Night?

Morning is the best time to use vitamin C. Its antioxidant protection works alongside your sunscreen to help defend your skin during the day. Vitamin C does not replace sunscreen, so always apply a broad-spectrum sunscreen after it.

What to Pair Vitamin C With

• Alpha arbutin and ferulic acid: Work with vitamin C to target uneven tone and boost stability. Our Vitamin C Serum combines 15% vitamin C with both.
• Hyaluronic acid: Adds hydration.
• Niacinamide: Can be used in the same routine or at night, for example with our Night Cream.
• Salicylic acid: Use vitamin C in the morning and salicylic acid, like our Acne Serum, at night.

Tips for Best Results

• Start every other morning if your skin is sensitive, then use it daily.
• Keep the bottle tightly closed and away from heat and sunlight.
• Do a patch test before first use.
• Be consistent: results build over weeks, not days.

When Will You See Results?

Most people notice brighter, more radiant skin within 3 to 4 weeks. Dark spots and uneven tone usually improve more visibly after 8 to 12 weeks of daily use with sunscreen.

Can Vitamin C Help Acne Marks?

Yes. Vitamin C and alpha arbutin help fade the dark marks left after breakouts. Read more in our guide on how to remove acne marks.
