Light Concept Nails (LCN) are a cosmetic fingernail product manufactured by German company Wilde Cosmetics. An alternative to acrylics, they are made of a gel-like, light cured resin. They are safer, more natural in appearance, and more durable than acrylic nail products, and they are non-porous, so they protect the natural nail and do not discolor over time.The resin used to make Light Concept Nails originated as a dental product created by Wilde Dental, founded in 1915. In 1985, LCN hit the cosmetics market. The product is currently only available in salons, as experienced technicians are required to apply it. It is first applied as a gel to the fingernails, then the nails are placed in a light unit for two minutes to cure, or harden. Unlike acrylics, there are no harsh chemicals or unpleasant odors involved in the application.Part of the durability of Light Concept Nails comes from their flexibility, which prevents cracking and breakage. They are best for people who wish to keep their natural nails, as other products, particularly acrylic, can damage the natural nail over time. LCN gel is available in a variety of colors. A clear coat provides a natural look, but the customer can also choose to have permanently colored nails, such as a permanent French manicure. Maintenance applications are required every three to four weeks at least.
