“I was hesitant because of the price, but after 3 weeks using it 10 min a day, my skin feels noticeably firmer and my fine lines are smoothed out. Best investment for my skin.”

Why skin loses firmness starting in perimenopause
As estrogen levels gradually decline, skin can lose up to 30% of its collagen in the first 5 years of menopause. The epidermis thins, cellular renewal slows, skin dries out, and expression lines become deeper.
Some women also experience localized hormonal blemishes or redness. Most cosmetic creams only work on the surface of the epidermis: they provide temporary comfort, but cannot biologically reactivate depleted cells deep below.
Why 4D phototherapy works where topical creams stop
Unlike surface treatments, the 4D mask's 236 diodes emit targeted light spectrums (including 850nm near-infrared and 1064nm deep infrared) that penetrate painlessly through the epidermis. They directly reach deep dermal fibroblasts to reactivate natural collagen and elastin synthesis.
4 targeted light spectrums to smooth and firm
Unlike conventional devices that emit only one or two colors, our mask combines 236 diodes across 4 complementary wavelengths to meet all mature skin needs.
Blue Light (460 nm)
Purifies the epidermis, soothes mild inflammation and rebalances occasional hormonal blemishes.
Red Light (665 nm)
Stimulates collagen and elastin synthesis to smooth the depth of fine lines and expression wrinkles.
Near Infrared (850 nm)
Penetrates the dermis to boost microcirculation, improve overall firmness, and support facial contour definition.
Deep Infrared (1064 nm)
Targets the deepest dermal-epidermal layers for intense and lasting cellular regeneration.
