Tackling the Root Causes of Breakouts
Our unique formula, Silver Chitoderm®, supports clearer skin by addressing key contributors to blemishes through a dual-action approach.
Lab testing shows Silver Chitoderm® is proven to kill 99.9% of C. acnes - the bacteria most commonly linked to breakouts.
Studies also found it helps reduce bacteria that can worsen inflammation and delay skin healing - promoting a calmer, clearer-looking complexion.
Our best-selling serum demonstrated a 99.9% reduction in Cutibacterium acnes (C. acnes),the bacteria responsible for acne, within 30 seconds.
Silver Chitoderm® doesn’t just fight bacteria, it helps your skin recover, too. The Chitoderm™ is naturally calming, making it ideal for inflamed, sensitive skin caused by hormonal changes, stress, or stubborn breakouts.
Breakouts around the jawline and chin caused by hormonal imbalances.
Flare-ups caused by stress hormones like cortisol.
The formula has been tested for sensitivity (HRIPT testing) and found to be hypoallergenic and kind to the skin.
Since our formula is lightweight and non-comedogenic, it won’t clog pores even if you’re wearing masks or heavy skincare.
What sets 47 Skin apart is how our products support your skin beyond the breakout.
Silver Chitoderm® doesn’t just target the bacteria that cause spots - it also promotes skin regeneration, helping to reduce the appearance of marks, uneven tone and visible redness.
At the same time, it hydrates and strengthens your skin barrier, leaving it feeling smoother, more resilient, and less prone to future flare-ups.
With over 5,000 customer reviews and success stories, the findings from the lab underscore the trust and effectiveness that 47 Skin products deliver, reinforcing our lab-based findings with real-world results.
