As beauty consumers increasingly seek dermocosmetic solutions for their daily skincare needs, devices that deliver salon-quality skincare treatments at home have boomed as a category. Taking inspiration from dermatological treatments, the Lightinderm skincare device was launched after 7 years of research and development within the auspices of Paris Santé Cochin - Europe’s largest start-up incubator in the health sector located within the Hospital Cochin in Paris, France.

“Light paradox”

The device uses the beneficial effects of certain wavelengths of light to treat the skin. "While light contains potentially dangerous UVA and B, its spectrum also contains certain wavelengths capable of a in depth and powerful stimulation of the skin’s self-repair processes. By selecting these wavelengths and associating them, it is now possible to go further than traditional cosmetics in order to treat a whole series of skin problems that have been poorly addressed so far”, explained Géraldine Decaux, founder of the brand.

The device uses three types of regenerative light to transform and activate the encapsulated photo-active serums to trigger the skin’s deep regeneration and rejuvenation mechanisms, when applied.

Custom design

Within the device, the airless roll-on capsule enables secure housing and delivery of different formulas according to the customer’s preference and skincare requirements.

For more than two years, Aptar Beauty + Home has developed for Lightinderm a removable capsule system with a personalized design. Inside the capsule, which has a guaranteed seal, is an airless piston designed exclusively for Lightinderm.

One of the main technical challenges was also to combine materials resisting to the impact of light rays while being able to diffuse them effectively, so as to activate the active ingredients contained in the serum, while offering a food or medical quality grade compatible with the different formulas. After extensive laboratory and industrial testing, the designers hit on three materials - the combination of which remains a tightly guarded secret - for the final airless roll-on capsule, which is fully recyclable. The recharge capsule consists of three parts made by Aptar, combined with the glass roller ball through which the light passes as it evenly distributes the formula and mechanically massages the skin.

The technical achievement of creating an airless roll-on capsule was made possible thanks to the cutting-edge technologies and expertise across various disciplines present at Aptar’s industrial sites across France. Aptar’s capacity for next-level research and large-scale testing, undertaken in close collaboration with the client, was key to producing this revolutionary product for Lightinderm,” said Aptar Beauty + Home in a release.
