How to Use Vitamin C 20% Serum

Follow this dermatologist-recommended routine for maximum brightening results.

1
AM Only
Cleanse and Prep
Start by washing your face with a cleanser to remove dirt and oil. Pat your skin completely dry with a clean towel to ensure the serum absorbs effectively.
2
AM Only
Dispense the Serum
Place a few drops of the Eternal Bright Vitamin C formula onto your fingertips. This precise amount provides a concentrated dose of brightening antioxidants for your skin.
3
AM — Key Step
Apply and Massage
Gently press the serum into your face and neck using upward circular motions. Massage until the liquid is fully absorbed to help firm the skin and boost natural radiance.
4
AM Only
Moisturize and Protect
Seal in the active ingredients with a hydrating moisturizer. For daytime use, always apply a broad-spectrum sunscreen to protect your glow from UV damage and oxidation.
💡
Pro Tip:For best results, use Vitamin C Serum every morning. Pair with Niacinamide Serum at night for complete brightening + pore care routine. Avoid mixing with Retinol in the same application. Most users notice brighter, fresher-looking skin within 3–4 weeks of consistent morning use.

I've tried so many Vitamin C serums — all overhyped, all disappointing. Eternal Bright is the real deal. My skin tone has visibly evened out in just 3 weeks. The texture is lightweight and absorbs instantly. Zero sticky feeling!

I was skeptical about the 20% concentration but it's incredibly well-formulated — zero irritation. My hyperpigmentation from sun damage is significantly lighter. My dermatologist was impressed by the formulation quality.
