Why Use Vitamin C for Skin?
Vitamin C is one of the most powerful skincare ingredients out there. When applied topically, it helps:
- Brighten dull skin
- Fade dark spots and acne scars
- Boost collagen for firmer skin
- Protect against sun and pollution damage
And the best part? You don’t need a $60 serum to get those benefits. This DIY version lets you make it fresh, so it’s super effective without the preservatives or mystery ingredients.

Supplies You’ll Need
To make this 20% vitamin C serum at home, gather the following:
Ingredients
- 1 ½ tsp vitamin C powder (L-ascorbic acid or orange peel powder)
- 5 ½ tsp distilled water
- 1 ½ tsp vegetable glycerin
Tools
- Glass mixing container (non-metal)
- Funnel with narrow tip
- Measuring spoons (½ tsp and 1 tsp)
- Dark glass bottle (to protect the serum from light)
- Spoon or stirrer
How to Make the DIY Vitamin C Serum
Follow this step-by-step process to make your own serum at home.
Step 1: Measure and Mix the Vitamin C
Use a teaspoon and a half of L-ascorbic acid powder (or a fine orange peel powder). Place it in a clean glass container.
Step 2: Add the Water
Pour in 5 ½ teaspoons of distilled water. Stir gently to begin dissolving the powder.
Step 3: Add Glycerin
Mix in 1 ½ teaspoons of vegetable glycerin. This makes the serum smooth and adds moisture to your skin.
Step 4: Combine and Store
Stir well until the powder dissolves completely. Use a funnel to pour the mixture into a dark glass dropper bottle to keep it fresh and stable.
Optional: You can refrigerate it and use it within 1-2 weeks for the best results.
How to Apply Vitamin C Serum
- Cleanse your skin thoroughly.
- Apply toner (optional).
- Use 2-3 drops of the serum and gently pat onto your face, neck, and backs of hands.
- Follow with moisturizer and sunscreen (especially in the morning).
Use it once a day at first, then gradually work up to twice a day if your skin tolerates it well.

My Results: Before and After
After using this serum consistently morning and night for a few weeks, I noticed:
- Softer texture (even on the backs of my hands!)
- Fewer dark spots
- Brighter, more even-toned skin
And because it cost less than $1 to make, I don’t have to skimp on how much I use—it’s a full face, neck, and hand treatment every day.

Bonus: DIY Hyaluronic Acid Serum
If you want extra hydration, follow up with a homemade hyaluronic acid serum. Here’s a quick version:
Ingredients:
- 1 tsp hyaluronic acid powder
- 7 tbsp distilled water
- ½ tsp glycerin
Mix and refrigerate for 4–6 hours until it thickens. Use after vitamin C serum for plump, hydrated skin.

Tips for First-Time Users
- If you’re new to vitamin C, start with a 5-10% solution to see how your skin reacts.
- Always do a patch test before using on your face.
- Store in a cool, dark place and make small batches to keep it fresh.
- For sensitive skin, try mixing the serum with your moisturizer at first.
