Vitamin C is one of the most talked-about skincare ingredients — and for good reason. From brightening dull skin to fading pigmentation, the benefits of Vitamin C extend far beyond basic skincare. Dermatologists at Dr. Hanan Clinic, Chennai often recommend Vitamin C as a daily essential for those seeking radiant, youthful skin.
In this guide, you’ll learn how Vitamin C works, how to use it safely, and when it’s most effective — along with its pros and cons from a dermatologist’s perspective.
What Is Vitamin C and Why It Matters for Skin
Vitamin C (ascorbic acid) is a powerful antioxidant that helps protect the skin from free radicals caused by sun exposure, pollution, and stress. It supports collagen production, reduces pigmentation, and helps your skin maintain a healthy glow.
At Dr. Hanan Dermatology Speciality Clinic, we emphasize that using Vitamin C topically provides faster and more targeted results than oral supplements for most skin concerns.

Benefits of Vitamin C for Skin
Brightens Dull Complexion
Vitamin C inhibits melanin production, reducing dark spots and evening out skin tone. Regular use gives the skin a visible radiance within weeks.
Boosts Collagen and Elasticity
Collagen keeps your skin firm and youthful. Vitamin C helps stimulate collagen synthesis, reducing fine lines and sagging.
Reduces Hyperpigmentation and Melasma
For patients struggling with melasma or post-inflammatory pigmentation, Vitamin C is a dermatologist-approved brightening ingredient.

Protects Against Sun and Pollution Damage
Vitamin C neutralizes free radicals generated by UV rays and pollution, preventing premature aging and oxidative stress.
Speeds Up Healing
It assists in repairing damaged skin and reducing redness or irritation after dermatological procedures such as chemical peels or laser therapy.
How to Use Vitamin C in Your Skincare Routine
Cleanse First
Start with a gentle cleanser suitable for your skin type to remove oil, makeup, and impurities.

Apply Vitamin C Serum at Night
Nighttime is the ideal period for Vitamin C application because your skin naturally repairs and regenerates while you sleep. Applying Vitamin C before bed enhances collagen production and brightens dull skin overnight. Use 2–3 drops on clean, dry skin before moisturizer.
Lock in Moisture
Follow with a hydrating, non-comedogenic moisturizer to seal in the serum and prevent transepidermal water loss during the night.
Morning Routine Tip
The next morning, always apply sunscreen (SPF 30 or higher) to protect your skin from UV rays and maintain the brightening benefits achieved overnight.
Dermatologist Insight from Dr. Hanan Clinic:
Using Vitamin C at night reduces oxidation from sunlight and pollution, giving more consistent results for dullness, pigmentation, and fine lines.
When to Use Vitamin C
- Morning: Best for daily antioxidant protection.
- Evening: Helps recovery after exfoliation or dermatological treatments.
- Post-Treatment: Vitamin C can be added after procedures like microneedling or laser resurfacing (once approved by your dermatologist).
Remember: Over-layering Vitamin C with acids or retinol can cause irritation. Space them out between morning and night routines.
