Light Concept Nails (LCN) are a cosmetic fingernail product manufactured by German company Wilde Cosmetics. An alternative to acrylics, Light Concept Nails 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. Light Concept Nails are 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 of light concept nails.

Part of the durability of Light Concept Nails comes from their flexibility, which prevents cracking and breakage. Light Concept Nails 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.

Many consumers believe that Light Concept Nails are the best cosmetic nail product on the market. There are other gel nail products, but Light Concept Nails are the first and most highly regarded. However, they are very expensive, costing anywhere from 45 to 85 US dollars (USD) for a complete set. It is also difficult to find salons that provide the product, and it can take years for technicians to master the application process. This can be a particular problem for people who need a reapplication if they are not near the salon where they originally had their Light Concept Nails applied.

If you are considering getting Light Concept Nails, make sure that you are getting your money's worth. The salon you go to should have an experienced technician, and the LCN product should be visible. If the technician uses gel out of unmarked pots, chances are he or she is using a different, cheaper gel product. Many consumers feel that Light Concept Nails are well worth the extra expense if applied well.
