What Is Vitamin C Serum?
Vitamin C serum is a lightweight, fast-absorbing liquid product that delivers a concentrated dose of Vitamin C directly to the skin. Vitamin C (ascorbic acid or its derivatives) is a powerful antioxidant that helps neutralize free radicals, boost collagen production, reduce hyperpigmentation, and brighten the complexion.
Many people in Bangladesh and around the world have incorporated this skincare hero into their daily routine — and for good reason.
Benefits of Using Vitamin C Serum
Before we dive into how to use vitamin C serum, let’s understand why you should use it:
1. Brightens Skin Tone
Vitamin C inhibits melanin production, which helps fade dark spots, acne scars, and uneven skin tone. Regular use results in a visibly brighter and more radiant complexion.
2. Boosts Collagen Production
As we age, collagen production decreases. Vitamin C stimulates collagen synthesis, helping reduce the appearance of fine lines and wrinkles.
3. Fights Free Radical Damage
Environmental aggressors like UV rays and pollution cause free radical damage, leading to premature aging. Vitamin C’s antioxidant properties protect your skin against these damages.
4. Improves Skin Texture
With consistent use, vitamin C can smoothen rough patches, reduce redness, and improve overall skin texture.
5. Reduces Under-Eye Circles
Vitamin C is also known to hydrate and plump the delicate under-eye area, reducing puffiness and dark circles.
When to Use Vitamin C Serum
You can use vitamin C serum either in the morning, at night, or both. However, morning use is ideal because it enhances your skin’s protection against environmental stressors throughout the day.
How to Use Vitamin C Serum Properly
Here is a step-by-step guide on how to apply vitamin C serum for the best results:
Step 1: Cleanse Your Face
Start with a gentle cleanser suitable for your skin type. This removes dirt, oil, and impurities, allowing the serum to penetrate better.
💡 SUNDORIKA Tip: Try the BIOAQUA Rice Raw Pulp Cleanser Facial Scrub Foam, available on Sundorika, for a refreshing deep clean.
Step 2: Use a Toner (Optional)
Toners help balance your skin’s pH and prepare it for better serum absorption. If you use a toner, apply it right after cleansing.
Step 3: Apply Vitamin C Serum
- Use 2-3 drops of serum.
- Gently pat it onto your face and neck using your fingertips.
- Avoid the eye area unless the serum is specifically designed for it.
🕒 Wait for 1-2 minutes before applying other products to let the serum absorb fully.
Step 4: Follow with a Moisturizer
A moisturizer helps lock in the serum and keeps your skin hydrated. Use a lightweight or hydrating moisturizer based on your skin type.
💡 SUNDORIKA Pick: Explore our collection of hydrating moisturizers suitable for oily, dry, or combination skin.
Step 5: Don’t Forget Sunscreen (If Daytime)
Sunscreen is non-negotiable. Vitamin C can make your skin more sensitive to sunlight. Apply a broad-spectrum sunscreen with SPF 30 or higher.
🛡️ Pro Tip: Never skip sunscreen, even on cloudy days.
How to Choose the Best Vitamin C Serum in Bangladesh
Shopping for skincare can be overwhelming. Here’s what to look for when buying a Vitamin C serum on SUNDORIKA:
