How to Use

Step 1: Cleanse your face thoroughly and follow with your toner. Allow the toner to fully absorb before applying the serum. Step 2: Dispense a few drops of the serum onto your fingertips. Step 3: Apply the serum to your face starting from the center — nose, forehead, and chin — and gently massage outward toward the edges of the face. Step 4: Use your fingertips to lightly pat and press the serum into the skin for better absorption. Do not rub. Step 5: Follow with your moisturizer to seal in the serum. In the morning, always finish with SPF to protect your brightening results. *Pro tip: Avoid mixing with retinol or exfoliating acids in the same routine. Use Vitamin C in the morning and actives at night. *For external use only. If irritation occurs, discontinue use.
