As we age, the skin’s natural ability to renew itself and repair its barrier slows down. Research on BeautiFerm® Healerine — the same concentration used in RENEW — shows it activates biological mechanisms involved in skin renewal:
Boosts Natural Regeneration — In vivo studies at 1% concentration showed 26.71% more regenerated tissue volume within 24 hours of skin disruption, compared to placebo.
Depth & Volume Reduction — 3D topography imaging recorded a 62% reduction in wound depth and a 21% reduction in total wound volume after 24 hours, at 1% concentration.
Essential Cellular Support — In vitro research shows Healerine stimulates the proliferation of keratinocytes — the cells responsible for maintaining skin homeostasis, a strong barrier, and healthy cell renewal. Separate lab testing recorded a 45% increase in the speed of epidermal re-epithelialization at 0.1% concentration.
Barrier Recovery — In a 28-day in vivo study, twice-daily application reduced skin barrier recovery time by up to 26% — 5 days faster than the untreated control, following a chemical insult.
Calming Support — In vitro research shows Healerine lightly inhibits NF-κB transcription in skin cells, a pathway linked to inflammatory response
A resilient skin barrier is the skin’s first line of defense against environmental stress. BeautiFerm® Healerine acts as a natural solution to support barrier recovery:
Accelerated Recovery — In a 28-day in vivo study, skin barrier function recovered up to 3 days faster on average with twice-daily application, compared to placebo — with the best responders recovering up to 6 days faster.
Visible Calming — Skin treated with Healerine showed visibly reduced redness and no crusting, compared to placebo, in imaging taken 24 hours after treatment.
Unlike standard extracts, our ingredient is a postbiotic created through a strictly controlled biotechnology process:
Enhanced Bioavailability — Fermentation research shows this process improves how skin can access and use the Reishi mushroom’s naturally occurring compounds.
Microbiome Friendly — This aqueous fermented active supports a balanced and healthy skin microbiome.
Broad-Spectrum Bioactives — Fermentation unlocks a rich profile of Reishi mushroom compounds, including triterpenoids, beta-glucans, and immune-supportive proteins, each contributing to the skin barrier and skin’s natural defenses.
