Our skin microbiome active for oily skin

Skin bioactives

Our sustainable, organic bioactive to reduce skin oiliness and Cutibacterium acnes levels

ALPAFLOR® ALP®-SEBUM is a natural, sustainable plant extract from from Epilobium fleischeri. It moderates sebum production, the main cause of oily skin, by inhibiting the key enzyme 5-α-reductase.  New studies show that this skin active also helps reduce sebum levels by down-regulating Cutibacterium Acnes - a gatekeeper that can influence sebum production. This bioactive ingredient is ECOCERT, COSMOS, and NATRUE organic certified and Fair Trade approved by Ecocert Environnement.

Mode of Action

Sebum production is regulated in the sebaceous glands by hormones such as testosterone and dihydrotestosterone (DHT). The inhibition of 5α-reductase is the most efficient way to visibly decrease sebum production. Studies demonstrated that the application of ALPAFLOR® ALP®-SEBUM significantly inhibits the activity of 5α-reductase and reduces the sebum production, which leads to a visibly clearer skin.

In our latest research, our experts found that ALPAFLOR® ALP®-SEBUM down-regulates Cutibacterium acnes levels thus helping to reduce sebum over-production and to control oiliness on prominent areas of the face such as the forehead.

By influencing Cutibacterium acnes levels in the skin microbiome as well as sebum production, DSM’s ALPAFLOR® ALP®-SEBUM is a powerful skin care ingredient for reducing oiliness and achieving beautiful-looking skin.
