Vitamin C is a powerhouse ingredient for brightening, firming, and protecting the skin. It neutralizes free radicals, boosts collagen synthesis, and even out‑tones uneven patches. While store‑bought serums can be pricey and often contain fillers, you can easily craft a potent, low‑cost DIY vitamin C serum in just three simple steps. This homemade vitamin C serum recipe for radiant skin is both affordable and customizable, whether you’re dealing with acne‑prone skin or sensitive complexions.
Ingredients & Tools You’ll Need
- Vitamin C powder (100 mg or 0.1% in a 1 oz vial) – a beginner‑friendly DIY vitamin C serum powder concentrate blend for beginners.
- Distilled water (1 oz) – ensures no impurities oxidize the vitamin C.
- Lemon juice (2–3 drops) – a natural source of vitamin C that also provides mild exfoliation.
- Vitamin E oil (0.5 drops) – acts as a preservative and antioxidant boost.
- Acetone‑free cotton swab or clean glass dropper.
- Tiny dark glass dropper bottle (1 oz) with a tight‑sealing cap.
Homemade Vitamin C Serum Step‑by‑Step Guide
Step 1: Prepare Your Powder Concentrate
Measure 1 oz of distilled water into a small bowl. Slowly sprinkle 100 mg of vitamin C powder into the water while whisking gently. The powder should dissolve to form a clear, slightly amber solution—this is your base concentrate. If any clumps remain, strain through a fine‑mesh sieve.
Step 2: Add Lemon Juice & Vitamin E
Drop in 2–3 drops of fresh lemon juice – it not only adds a natural source of vitamin C but also helps to lower the pH, improving serum absorption. Add 0.5 drops of vitamin E oil and give the mix one more gentle stir. The serum will turn a light golden hue.
Step 3: Transfer & Store
Sip the mixture into a clean dark glass dropper bottle using a cotton swab or dropper. Seal tightly and refrigerate. Your fresh, homemade vitamin C serum is now ready to apply daily in the morning or at night after cleansing.
Tips, Variations & Low‑Cost DIY Vitamin C Serum for Acne‑Prone Skin

- For acne‑prone skin: Mix a few drops of tea tree oil (0.5 drops) alongside the vitamin C solution to add antibacterial properties.
- For sensitive skin: Reduce the lemon juice to a single drop or omit it entirely, relying solely on the vitamin C powder.
- Brightening burst: Add a pinch of beetroot powder (around 0.5 g) for an extra antioxidant boost and a natural color shift.
- Storage tip: Keep the serum in the refrigerator and use it within 30 days to maintain potency.

Safety & Precautions – How to Make Vitamin C Serum at Home with Lemon Juice Safely
While homemade vitamin C serum is inexpensive, the active ingredient can oxidize or cause irritation if not handled correctly. Use high‑purity vitamin C powder and keep the serum refrigerated. Perform a patch test on your inner forearm before applying to face. If you have active breakouts, start with a lower concentration (50 mg) and gradually increase as tolerance builds.
