Learn how to use the Plus C 20% Vitamin C Serum and Peptide Brightening Sheet Mask together for a brighter, more even complexion. Step-by-step routine inside.

Quick answer

Use the Plus C 20% Vitamin C Serum in your morning routine, then follow with the Peptide Brightening Sheet Mask once or twice a week for an extra glow boost.

Why these two products work together

The Plus C Serum delivers L-Ascorbic Acid and grapeseed extract to protect against free radical damage and improve skin elasticity. The Peptide Brightening Sheet Mask adds a concentrated dose of peptides to support firmness and radiance. Using them in the same routine—but not at the exact same time—lets each formula work without interference.

How to use Plus C Serum + Peptide Mask for brighter skin

Step 1: Cleanse and dry your face: Start with a clean, dry face. Apply 3–4 drops of Plus C 20% Vitamin C Serum to your fingertips and gently press onto your skin, avoiding the eye area. Wait 60 seconds for the serum to absorb. Do not apply the serum on damp skin—it can dilute the L-Ascorbic Acid and reduce absorption.
Step 2: Follow with moisturizer and sunscreen (AM routine): After the serum has absorbed, apply your regular moisturizer and then a broad-spectrum sunscreen. Vitamin C boosts sun protection, but it is not a substitute for SPF. Skipping sunscreen can undo the brightening benefits and increase sensitivity to UV rays.
Step 3: Use the Peptide Brightening Sheet Mask 1–2 times per week: On a clean face (no serum), unfold the sheet mask and apply it evenly. Leave on for 15–20 minutes, then remove and gently pat the remaining essence into your skin. Do not rinse. Do not leave the mask on longer than 20 minutes—it can dry out and pull moisture from your skin.
