The SOS Instant Relief Moisturizing Mask is a velvety mask that can be left on or washed off. It is enriched with moisturizing sugar, smoothing hyaluronic acid, and an anti-aging blend of flaxseed and peony. Easy to use, it leaves skin feeling supple, smooth, pleasantly firm, and protected from future dehydration. Use twice a week or whenever skin is dry, dehydrated, and stressed. Apply to cleansed skin. Leave on or gently wash off after 15 to 20 minutes with a damp cloth or cotton pad
