La Paz Obtains Patent for Micro-Needle Technology Using Anti-Aging Ingredient 'Pure Retinol'

[Asia Economy Reporter Hyunseok Yoo] Lapas announced on the 31st that it has obtained a patent for the manufacturing of ‘soluble microneedles,’ which significantly enhance the preservation and stability of retinol, the main ingredient in anti-aging cosmetics, allowing retinol to be directly applied to the skin.

Retinol is a functional ingredient known for its excellent anti-wrinkle and anti-aging effects, but due to its incomplete composition, it easily decomposes into an inactive state when exposed to light or heat. Therefore, its instability when applied to the skin as a cosmetic ingredient has been pointed out as a major issue.

Since advanced formulation stabilization technology is essential to use retinol as a raw material, cosmetics sold on the market so far have used ‘retinol derivatives,’ which have improved stability but lower efficacy, rather than using ‘retinol’ itself as an ingredient.

Lapas has focused on research and development for several years and succeeded in developing a microneedle manufacturing method that can improve the stability of retinol. Through obtaining this patent, the preservation and stability of retinol have been secured. The company explained that it is significant because it proved that its proprietary ‘DEN microneedle’ manufacturing technology is an effective alternative for applying unstable active ingredients.

Hyunwoo Park, Head of Lapas Cosmetics Division, said, “It was difficult to achieve retinol stabilization in topical cosmetics, but through the microneedle manufacturing method, we have successfully applied retinol as a cosmetic ingredient,” adding, “It is encouraging that microneedle technology has been applied in the cosmetic field.”

He continued, “We plan to develop anti-aging microneedle cosmetics,” and added, “Although other ingredients have excellent efficacy, their compositions are unstable, so we will expand the application scope of microneedle formulation technology to those ingredients.”
