Inventiva uses nanotechnology to reduce the side effects of retinol

Retinol is regarded as one of the most powerful active ingredients in the cellular renovation process, but side effects such as skin irritation and peeling led to it being gradually replaced by other ingredients in skin care formulations.

However, the signs are that retinol has just won a new chance with the cosmetics industry. Following groundbreaking research and development, Brazilian company Inventiva launched NanoRetinol using nanotechnology to encapsulate the active ingredient, thus reducing its toxicity. The technology is recommended for gels, emulsions and serums.

NanoRetinol was assessed clinically and in cell culture at the Syntivia laboratory in France. Inventiva pharmaceutical director Cândice Felippi said the results showed that not only did nanotechnology reduce the side effects when applied to retinol but also increased the synthesis of collagen in skin cells by 26%, thereby enhancing the cellular renovation process and reducing wrinkles and expression lines.

Nanotechnology allows active ingredients to be encapsulated and transformed into nanoparticles. They can penetrate the deepest layers of the epidermis, strengthening and extending the effects of moisturizing, preventing, repairing and protecting the skin, hair and nails.

The reduced side effects are attributed to the fact that the skin has no direct contact with the retinol, but with the wall of nanoparticles that are made up of natural raw materials, such as vegetable oils and butters. They have a great affinity with the skin and do not cause any kind of reaction, irritation or peeling.

In Brazil, products with retinol in their formulation must have a maximum concentration of 0.3%, under the standards of the National Health Surveillance Agency, ANVISA. NanoRetinol contains 1% of retinol and allows an incorporation of up to 30% in cosmetic formulations to meet the permitted standards. For anti-ageing products, Inventiva recommends a concentration of 1% to 10% of NanoRetinol, while the recommended concentration for BB Creams is 0.5% to 3%.

Inventiva was founded in 2008 and is based in Rio Grande do Sul. The company has its own laboratory and specializes in the production of cosmetic active ingredients for skin, hair, body and nail care, using nanotechnology as a resource.
