Lactic Acid 

An AHA derived from fermented milk, Lactic Acid exfoliates the skin to improve texture and clarity. It has a larger molecule size than glycolic acid so can be a less irritating alternative for sensitive skins.

Lanolin 

A natural oil that comes from sheep’s wool. It has excellent moisturizing properties and is easily absorbed by our skin. Lanolin is also known to protect and soothe the skin. Used commonly in lip balms, moisturizers etc.

LED*
Light-emitting diode devices give off a narrow range of a specific wavelength of light. (Different wavelengths target different skin issues; for example, blue light kills the bacteria known to cause acne.) Much less intense than lasers or IPL, many LED devices are safe enough for hand-held use at home.
