and remained at this level throughout the four-week trial (22% reduction at 28 days). Microbiome analysis meanwhile showed an 11% reduction in Cutibacterium acnes after one week, stabilising at 7% after 28 days.
Reducing sebum and Corynebacterium kroppenstedtii to keep normal skin looking fresh Because Corynebacterium kroppenstedtii is associated with skin redness, keeping levels at a minimum could be beneficial to normal skin and maintaining a fresh complexion. The bioactive Saccharomyces lysate is
made from the extraordinary baker’s yeast strain VdH2 and contains powerful mitochondrial respiration activators. In DSM’s study, treatment with this ingredient was shown to reduce sebum levels on cheek skin by 5% after one week and 7% after 28 days while Corynebacterium kroppenstedtii levels were reduced by 65% after one week and still showed a reduction of 62% after 28 days.
Does the skin microbiome hold the key to beautiful looking skin? The skin microbiome is very diverse and its landscape still relatively unexplored. As more and more data becomes available in the coming weeks and months, a key focus will be to define standardised processes for research and analysis. This will require widening the range of skill sets traditionally called on, and input from multi-disciplinary teams, including microbiologists and biostatisticians.
By investigating specific skin conditions in
relation to established physiological parameters such as sebum and TEWL, and in parallel with skin microbiome analysis, DSM’s study provides a model for conducting tests in a way that generates reliable and meaningful data. Moreover, its preliminary findings about the correlation between the composition of the skin microbiome and changes in normal, dry and oily skin, and the beneficial effects of its three actives, point to promising potential for next generation skin care.
September 2019 As a new topic which is likely to be well-
received by consumers through their understanding of the gut microbiome, the skin microbiome offers a real opportunity for innovation in skin care. DSM is committed to staying at the forefront of understanding about this topic, by leading the way with new research and engaging with consumers, to develop original skin microbiome solutions.
