The HSR Overnight Mask combines the comprehensive HSR Anti-Aging Complex, which works against all types of wrinkles, with the power of SLEEPREVIVE. SLEEPREVIVE is an upcycled active ingredient derived from Australian tea tree oil, known for stimulating antioxidant synthesis and supporting the skin's overnight regeneration capabilities. It improves skin firmness, elasticity, hydration, and barrier function while reducing dark circles under the eyes. Additionally, the delicate lavender scent creates a relaxing effect. Result: refreshed, radiant skin after just one night. Application: Apply 1-2 times a week in the evening to cleansed skin on the face, neck, and décolleté using your hands. Massage in with a ritual if desired. Leave on overnight.
