@beauty_techgirl: The INIA 4D Dual Mask uses powerful 850nm + 940nm near-infrared light to support collagen production and skin tightening deep beneath the skin’s surface. Comment “mask” for the link! 💡 850nm NIR helps boost collagen for firmer, smoother looking skin. 💡 940nm NIR helps improve elasticity and the appearance of loose or sagging skin. What makes this mask unique is its extended design that reaches below the jawline, helping treat areas where aging often begins — the lower face and upper neck. #inia #inia4dmask #iniareview #redlightmask #redlighttherapy @INIA Official
