Our team’s advice: To use the BARULAB Steam Sheets Moisture Shield Oil Lock facial masks, first apply the mask to your clean, dry face. Make sure it adheres well to your skin by adjusting it around your eyes, nose, and mouth. Leave it on for 15 to 20 minutes to allow the active ingredients to penetrate effectively. Gently remove the mask and massage the remaining serum into your skin for optimal hydration. Use these masks regularly for visible results.
