Pumpkin fruit fermented with lactobacillus — the fermentation releases and concentrates the fruit’s proteolytic enzymes along with vitamins and amino acids.
How it works
Like papain, the ferment’s enzymes break down the protein bonds holding loose surface cells, exfoliating without friction or strong acid. Research associates fermented pumpkin with gentle keratolytic activity, and the fermentation itself adds skin-conditioning by-products.
Tolerability
Among the gentler exfoliating routes; still best kept off broken or actively inflamed skin, as with all exfoliation.
Pregnancy and breastfeeding
For exfoliating treatments generally, the conventional advice is to check with your doctor.
