Dr. Kasia
Wezowski
For more than a dozen years, Dr. Kasia Wezowski searched for skincare that could genuinely meet her expectations. She tried hundreds of creams, studied ingredient lists, compared formulations and closely observed how different products and combinations affected her own skin.
She wasn't simply looking for another luxurious cream. She wanted to understand what actually made a difference — which ingredients worked, how they worked together, and what happened when they were combined differently.
Over the years, this became a personal research project. With a background in psychology and a PhD from the University of Bristol, Dr. Kasia approached skincare with the same curiosity she brings to understanding human behaviour: observe, question, test and learn.
Eventually, she reached a simple conclusion. The cream she was looking for did not exist. So she created it.
I Wanted to See It
on My Own Skin.
SACRED was developed through years of personal experimentation — trying different skincare products, studying their ingredients and observing the effects on my own skin. I tested different approaches to hydration, barrier support, renewal and anti-ageing. I looked closely at how individual ingredients performed, but also at what happened when they were combined.
The goal was never to create the longest ingredient list. It was to find the right combination. The result is the formula I had been searching for: a membrane-based cream combining skin-identical lipids with powerful retinal, lipid-soluble vitamin C, peptide technology, antioxidants and multiple hydration systems.
I didn't create SACRED because I wanted another cream. I created it because I couldn't find the cream I wanted to use myself.

The Combination
Matters.
SACRED brings together technologies that are rarely found in this combination in a single night cream. At its foundation is a DMS-inspired membrane system built around Hydrogenated Phosphatidylcholine, Phosphatidylcholine and Hydrogenated Lecithin. This is combined with five ceramides — NP, AP, AS, NG and EOP — cholesterol and phytosphingosine to support the skin's barrier and lipid organisation.
For visible renewal, SACRED uses retinal, an advanced form of vitamin A that acts up to 11× faster than standard retinol, together with Palmitoyl Pentapeptide-4 for anti-ageing support. For brightness and antioxidant protection, the formula contains Ascorbyl Tetraisopalmitate, a lipid-soluble vitamin C derivative, alongside vitamin E, EGCG and rosemary extract.
Niacinamide, ectoin, glycerin, sodium PCA, sodium lactate, urea and other moisturising factors support hydration and barrier function, while jojoba, grape seed, sunflower and shea provide nourishing lipid support.
The result is not simply a collection of active ingredients. It is the combination — and the way those technologies are brought together in one formula — that makes SACRED different.
