The France-based company has launched the ingredient, Kelisoft, in recognition of the desire from both men and women to shave less often, it said.
Kelisoft’s action relies on regulating the production of the inflammatory mediators PGE2, IL8 and VEGF.
Soothing sensation after shaving
According to the company, these mediators not only stimulate hair growth, they are also involved in the burning sensation often experienced after shaving – giving the ingredient a double action.
“The metabolism of hair growth and inflammation are linked together,” a Sederma spokesperson told CosmeticsDesign-Europe.com.
IL8 and VEGF have a pro-mitotic effect on human keratinocytes and both PGE2 and VEGF are responsible for increased blood flow to the tissues. In addition, VEGF increases tissue irrigation, thereby resulting in hair growth, the spokesperson explained.
Slower and finer growth underarms
A study carried out on 20 female volunteers, who used the ingredient formulated at 3 per cent into an underarm solution, twice daily for two months, illustrated slower and finer hair growth, Sederma claimed.
In addition, the company tested the efficacy of the ingredient when formulated into a gel-cream for the face at 4 per cent. After two months of a once daily application to the beard area of male volunteers, the hair growth speed was reduced, it claimed.
The ‘5 ‘o’ clock’ shadow was delayed by three hours, Sederma said, and applying the cream gave a soothing sensation after shaving.
According to the company spokesperson, 90 per cent of the study participants found their hair less vigorous after two months of using a Kelisoft-containing product.
Sederma claims that while there are other hair growth minimisers on the market, Kelisoft is the first to be available in both oil and water soluble versions. In addition, it says it is the first ingredient to be tested on the underarm area.
