Vitamin C has become one of the most powerful skincare ingredients, recommended by dermatologists worldwide. It brightens skin, fades pigmentation, and protects against premature aging. But like any active ingredient, Vitamin C isn’t completely risk-free. Some people may experience side effects if they use it incorrectly or choose the wrong formulation.

The good news is — most side effects are mild, temporary, and easily preventable with the right product and usage. In this blog, we’ll explore the common side effects of Vitamin C face serums, how to avoid them, and why CLARIV 10% Vitamin C Serum is one of the safest and most effective options for Indian skin.

Common Side Effects of Vitamin C Serum

1. Skin Irritation

• What happens: Redness, tingling, or mild burning sensation.

• Why: Often caused by high concentration (15–20%+) or unstable Vitamin C forms.

• How to prevent: Start with 5–10% concentration; patch test before use.

2. Purging (Temporary Breakouts)

• What happens: Small pimples or bumps appear in the first 1–2 weeks.

• Why: Vitamin C accelerates skin turnover, pushing out impurities.

• How to prevent: Be patient; purging usually clears within 2–3 weeks.

3. Dryness or Flakiness

• What happens: Skin feels stretched or flaky.

• Why: Overuse or pairing with other strong actives (like AHAs, retinol).

• How to prevent: Use moisturizer after serum; avoid layering too many actives.

4. Yellowing of Skin

• What happens: Skin or pillowcases develop slight yellow stains.

• Why: Oxidized Vitamin C (unstable formulas) can stain.

• How to prevent: Store serum in a cool, dark place; use stabilized Vitamin C.

5. Allergic Reactions (Rare)

• What happens: Persistent itching, swelling, or hives.

• Why: Fragrances, preservatives, or very high concentrations.

• How to prevent: Choose dermat-tested, fragrance-free serums; discontinue if reactions persist.

Who is More Prone to Side Effects?

• People with sensitive skin.

• Beginners starting directly with high concentrations (15–20%).

• Those mixing Vitamin C with strong actives like retinol, glycolic acid, or salicylic acid.

• People using oxidized serums (dark brown/orange color).

How to Avoid Side Effects of Vitamin C Serum

1. Start Low and Slow

   • Beginners → 5–10% Vitamin C (safe for daily use).

   • Once skin adjusts, you can move to higher concentrations if needed.

2. Patch Test First

   • Apply a drop on jawline/neck before using on full face.

   • Wait 24 hours to check for reactions.

3. Use with Moisturizer

   • Locks hydration, reduces dryness or tingling.

4. Always Pair with Sunscreen

   • Vitamin C makes skin more sensitive to sunlight if unprotected.

   • SPF 50 sunscreen ensures maximum results.

5. Store Properly

   • Keep away from heat & light.

   • Use dark bottles with airtight caps.

Myths About Vitamin C Side Effects

• ❌ “Vitamin C is unsafe for dark skin.” → False. It suits all skin tones.

• ❌ “Side effects mean it doesn’t work for me.” → Often, it’s just purging or wrong usage.

• ❌ “You must stop if you feel tingling.” → Mild tingling is normal in early use. Severe irritation is when you should stop.
