- Probiolift™: first cosmetic ingredient with live probiotic helps make the skin appear fuller and improves the appearance of forehead wrinkles
- Postbiolift™: postbiotic helps make the skin appear more elastic, smooths the appearance of crow’s feet wrinkles, and creates an appearance of an even complexion
- Cosmetic ingredients harness Lactobacillus crispatus bacteria that are abundant in young skin and considerably decreased in older skin
With Probiolift™ and Postbiolift™, BASF’s Care Creations® is introducing two new biotic ingredients that support healthful and graceful skin aging. Unlike other biotics existing on the cosmetic market, the newly developed ingredients are the first to use a bacterium that is found naturally in the skin: Lactobacillus crispatus (L. crispatus), a Gram-positive rod shape anaerobic bacterium that has been found to decrease with age.
“Consumers are increasingly aware of the health benefits that biotic ingredients offer, whether pre-, pro- or postbiotics. This trend has its roots in the food industry,” said Cécile Kalem, BASF Launch Manager for Active Ingredients in Europe. “What is common practice in this field has, up to now, been one of the most challenging tasks for the personal care industry: incorporating living skin bacteria into cosmetic formulations and keeping them active. With Probiolift, we have found a solution for this challenge – a real breakthrough by our research and development teams.”
New insights into changes in the facial microbiome upon aging
Complementing existing research that indicates skin microbiota diversity changes with age, BASF has conducted a new study on the difference in the facial microbiome composition of young and old people. The research team found that lactic acid bacteria, including Lactobacilli, noticeably decrease in mature skin. The L. crispatus specie in particular decreased in the undereye zone and was not detectable in the wrinkle hollow of the older volunteers. This finding has led BASF researchers to assume that L. crispatus, isolated from human skin, may be the key to more youthful looking skin. BASF has developed two cosmetic ingredients from the same biofermentation process: Probiolift, the probiotic with dormant cells of living L. crispatus, and Postbiolift, the fermentation supernatant containing the metabolites secreted by L. crispatus.
Probiolift™ for fuller skin with reduced appearance of wrinkles
Probiolift is made of living but dormant L. crispatus bacteria which awaken in contact with water on the skin. The ingredient thus unlocks a hitherto largely untapped potential in the biotic beauty sector. It promotes graceful skin aging by making the skin appear fuller, and improving the appearance of forehead wrinkles.
Twenty-nine female volunteers between the ages of 45 and 65, who had fine lines or wrinkles on their forehead, participated in the clinical study. The efficacy of a base cream formulation containing Probiolift at 0.05 percent was evaluated in comparison with a placebo base cream formulation. Probiolift made the volunteers’ skin appear fuller after two months. Although the appearance of forehead wrinkles is more difficult to smooth than crow’s feet, the new probiotic offered a visible correction in this area as well, achieving a 5 percent reduction in the appearance of wrinkles compared to the placebo. Clinical results were supported by L. crispatus biological properties shown in advanced in vitro testing.
Postbiolift™ for more elastic appearing, smooth and even skin
Postbiolift is a new and unique postbiotic ingredient containing beneficial metabolites secreted by L. crispatus. It supports an improvement in the mechanical properties of the skin to help make it appear more elastic, smooth the appearance of wrinkles around the eyes, and create an appearance of an even complexion.
The efficacy of Postbiolift was demonstrated in a placebo-controlled, clinical study with 30 female volunteers aged between 40 and 50 with crow’s feet wrinkles and color spots on the face. After 28 days and 56 days of treatment with the ingredient formulated at 1 % in a cream, the elastic parameters were evaluated. The results were significant compared to the placebo, with an improvement of up to 10 %.
In addition, at the end of the 56-day study, Postbiolift had significantly decreased the appearance of crow’s feet and pigmented age spots in these middle-aged women by almost 7 compared to the placebo. The mechanism underlying the observed clinical results has been evidenced by comprehensive in vitro studies.
Together, these two new ingredients are empowering cosmetics manufacturers to meet rising demand for clinically proven, biotic products that support youthful skin appearance.
