      Our founder, Alicia Yoon, struggled with eczema her whole life and has very sensitive skin. She, like so many people, had avoided retinoids because it was hard to find one that was potent, stable, and gentle enough for her sensitive skin. So we set out to create a retinoid that could actually meet all three criteria. Given how retinoids work, we knew this would not be a standard product development process, but would instead require a deep-dive innovation research project. We enlisted a village of experts: biochemists, formulators, and dermatologists to research novel ingredients and innovations.

      We decided that we would not launch a retinoid product until we had a breakthrough where potency, stability, and gentleness could live together – because your skin deserves the best. This meant there was no timeline on product development – simply because innovation can't be time locked. It took three years, hundreds of unique formula iterations, and an independent clinical study using instrumentation to determine more objective results. We're thrilled to share that Retinal For All delivers on all three pillars. We truly believe Retinal For All will help you tremendously on your skincare journey, no matter what your skin type and where you are in your own journey.
