DETAILS

This gentle leave on granactive retinoid serum helps promote a smooth, radiant-looking complexion while supporting skin clarity and hydration.

Our Pro+ Bio Resurfacing Retinol RX serum is the first in our range to combine postbiotic technology with a next-generation retinoid. This gentle formula is designed for those introducing a retinoid into their routine while maintaining skin comfort. The inclusion of Granactive Retinoid is balanced with soothing ingredients that help reduce the appearance of redness and support a visibly calm, even-toned complexion.

If you're easing into a retinoid routine, start with our Pro+ Bio Resurfacing Retinol ALT - a plant-based alternative featuring Bakuchiol to refine and visibly brighten the skin.

Kiri's Story

Before creating AMPERNA®, I lived with reactive skin. It was frustrating and often isolating, as I struggled to find products that didn’t make things worse.

That experience inspired me to develop a range that is gentle, simple, and supportive for skin, so others searching for calmer, more comfortable routines would have options they could turn to.

AMPERNA® is the result of that journey. Every product is guided by the same philosophy: kind formulations, inspired by real skin stories.
