Givaudan Active Beauty casts away stretch marks with Centella CAST

02 May 2022 --- Centella CAST, a natural molecule derived from green fractionation of the medicinal plant Centella asiatica, is being utilized by Givaudan Active Beauty to restore the skin elasticity, firmness and density lost during pregnancy.

“Centella asiatica is sustainably sourced in Madagascar thanks to a traceable process and to long-term and formalized relationship and good communication between the supply chain,” Pauline Martin, operational marketing and communication manager, tells PersonalCareInsights.  

In parallel, Active Beauty has formulated Body Confidence, a “light emulsion” consisting of Centella CAST to “fade the color of stretch marks over time” and improve skin collagen. 

“Body Confidence also features Marula oil (refined) to nourish the skin, Dragon’s blood [red resin] for strengthening properties and Bosexil for soothing effects,” says Active Beauty. 

Clinical evidence of epidermal thickness
The ingredient works by targeting the stretching of the skin to reduce the appearance of stretch marks. Within clinical tests on women, the molecule showed epidermal and dermal improvements.

“A clinical study with Centella CAST used at 0.5% has been conducted on 54 women in their postpartum period (at least six months after delivery),” continues Martin. 

“The active formulation has been controlled versus a control – application three times a day. The results demonstrate epidermal and dermal thickness, as well as dermal density, are important parameters to assess the cutaneous regeneration associated with the improvement of stretch marks.” 

“Epidermal thickness at the center of stretch marks improved by +39%, skin elasticity by +62%, skin microcirculation by +162% and skin appearance by +42%.” 

Martin adds: “Epidermal thickness, both at the stretchmark edge as well as at the stretchmark center, improved in the group treated with the active in a statistically significant manner.”

In clinical tests on women, the ingredient showed epidermal and dermal improvements.

Marking stretch marks
“Skin damage in stretch marks is normally focused on the dermis. We can observe disruption of the normal elastic fiber network, altered collagen fiber, loss of fiber organization and orientation, and erythema. As a result, the skin appears less firm and malleable, with visible stretch marks,” shares Giada Maramaldi, global category manager at Active Beauty. 

“Centella CAST efficiently counteracts these issues and helps skin regain elasticity and firmness. Thanks to these multiple mechanisms, it may also be applied head to toe featuring a global firming, anti-sagging effect.”

Although pregnancy causes stretch marks, striae can develop on anyone regardless of age or gender. 

The company shares that up to 86% of US consumers experience stretch marks during puberty. One in two women develops striae during pregnancy. 

Despite stretch marks not being a debilitating health concern, Givaudan notes how the marks can cause more mental self-confidence issues. 

“For example, 71% of women in France say they are concerned about the appearance of stretch marks,” shares the company. 

Adding to the actives portfolio
The company previously released Cristalhyal e-perfection, a white biotechnology-designed ingredient, charging hyaluronic acid molecules with electrostaticity for epidermal penetration. The high molecular weight hyaluronic acid is paired with a vectorized complex of bentonite clay. 

Furthermore, Patchoul’Up, a “100% upcycled” ingredient, was debuted as a solution to dry flakey scalp and to balance the scalp microbiome and the sebum production. The company shares that up to 86% of US citizens experience stretch marks during puberty. One in two women develops striae during pregnancy.

“The distillate leaves are dried and re-valorized in a side stream with an adapted process to give Patchoul’Up, an active ingredient obtained from upcycled patchouli leaves,” Pauline Martin, operational marketing and communication manager Active Beauty, previously told PersonalCareInsights.

Last, in the active ingredient launches, Neoporyl was unveiled by Active Beauty. The ingredient was designed to target the root cause of large pores within one week. Neoporyl was produced through biocatalysis technology using enzymes and amino acids.

The ingredient targets the root cause of parakeratosis, which damages the skin by altering the structure of the epidermis and affecting the dermis’ fragility.
