LED vs Laser: we tested the 2 best Beauty Tech devices

Its 99 red LEDs and 99 infrared LEDs send light energy to regenerate cells by penetrating the skin to reach the cell's energy center: the mitochondria. This triggers a biochemical reaction that reduces oxidative stress in the cell, the cause of cell ageing, loss of elasticity and skin inflammation, accelerating cell regeneration, slowing down skin ageing and helping skin regain its suppleness and firmness. What's more, LED power is optimized thanks to two coupled wavelengths that ensure a targeted approach so as not to dilute the power delivered to the heart of the cells.

How to use: 3 x 10-minute sessions per week for results in just a few weeks. 

Its benefits: The amount of light emitted by its LEDs that reaches the skin (also known as exceptional irradiance) acts in just 10 minutes to maximize skin benefits on blemishes, acne, redness, radiance, even skin tone, as well as hydration, elasticity and signs of aging.

• Signs of aging: it stimulates the production of collagen and elastin, key components for firm, younger-looking skin. It also helps reduce skin inflammation and increase hydration. As a result, it visibly rejuvenates the skin, slows the appearance of fine lines and wrinkles, and visibly diminishes crow's feet and nasolabial fold wrinkles. 

• Radiance: provides an immediate burst of radiance and evens out the complexion while regulating sebum, tightening pores and reducing the appearance of pigmentation spots and scars.

• Elasticity and firmness: reinforces skin elasticity and firms facial contours.

• Blemishes and acne: it has healing and soothing properties, helping to reduce acne scars, brown spots and skin imperfections. It also stimulates blood circulation, improving cell oxygenation and nutrient supply.

The little extra that really makes all the difference: Comfortable thanks to its extra-soft medical silicone, it's easy to use and perfectly suited to the eye, mouth and nose contours. 

It penetrates deep into the skin's layers to reactivate skin cells' ability to regenerate, stimulate collagen production, awaken tired skin cells and revitalize skin's appearance. 

Use: 3 minutes a day to transform your skin in 12 weeks. 

The results? More targeted, deeper and longer-lasting than LEDs, its results are clinically proven on issues such as spots, acne, eczema and rosacea, as well as scars, wrinkles, radiance and sagging skin. 

It allows you to act on : 

• Wrinkles: it stimulates collagen production in the dermis and epidermis, transforming fine lines and wrinkles in just a few days.

• Pigmentation spots: disperses melanin deposits in the base layer of the skin, to reduce the appearance of pigmentation and sun spots and even out skin tone.

• Redness: reduces inflammation in all skin layers, alleviating redness on the face and body. 

• Skin firming: lifts, sculpts and firms by stimulating collagen production and reinforcing the extracellular matrix to restore skin elasticity.

• Scars: it transforms scars by rebuilding skin microarchitecture and smoothing scar tissue. It accelerates the healing process by simultaneously treating all layers of skin, muscle and bone.

• Cellulite: reduces adipose tissue to smooth skin and reduce the appearance of cellulite.

• Muscular discomfort: effectively treats muscle damage and joint pain by stimulating microcirculation and energy production to speed up the healing process.

• Sports recovery: stimulates cell regeneration in damaged tissue to speed up the body's natural healing process and enhance muscle recovery.

The little extra that really makes all the difference: Easy to use (and take everywhere), it can even be applied over make-up, sun protection and around the eyes! 

What we (really) thought: "I'm an absolute fan of this new-generation device, which is particularly effective in treating my eczema/psoriasis problems locally and improving the quality of my skin all over my face. I've been using it religiously for 3 minutes a day for the past month and I can't do without it! Healing is accelerated, irritated skin is visibly soothed, skin is brighter and fine lines are reduced. But as with sport, assiduity is key!" - Fanny, Communications Director
