Our Patented Hero Ingredient: JellyCo PeP
Wonjin Effect is hospital-grade Korean skincare born from over 20 years of clinical research at Wonjin Aesthetic Hospital.
At the heart of every formula is our patented JellyCo PeP — a pharmaceutical-grade jellyfish collagen peptide developed and produced on the Wonjin Effect production line in our Korean clinical factory.
Specially created for Hispanic and Latina skin, JellyCo PeP controls inflammation that causes new manchas, fades dark spots, deeply hydrates to stop ashing, and reveals the radiant, confident Latina Glow you deserve.
Advancing through principles — never trends.
