No, you should not purchase the Soothe Rescue Mask instead of the Soothe Regimen. Based on Multi-Med Therapy, the Soothe Regimen is a comprehensive, twice-daily skincare routine designed to reduce visible redness and relieve dry, irritated skin for a moisturized, healthy-looking complexion. The Soothe Rescue Mask was formulated for use in conjunction with Regimen routines, including the Soothe Regimen. Although the Soothe Rescue Mask was formulated with unique ingredients to address the manifestations of skin sensitivity, it will not replicate the results of the Soothe Regimen.
