About Us

History of Miller Marsh
The founders, Rachel Miller and Brittany Marsh, havea been friends for many years here in Arkansas, and saw the need to create a fabulous skincare line with high-end ingredients, often seen at a much more expensive price point.
Brittany Marsh owns a local pharmacy, Cornerstone Pharmacy at Rodney Parham in Little Rock and Rachel Miller is the owner and nurse injector of RSM Aesthetics in Little Rock..
After seeing many patients and using many different products, Rachel decided to put together her own serum and approached the pharmacy for help.
Rachel saw the need for a higher-grade skincare product that would make big changes in her patients’ skin, that was affordable, and that was clean – no parabens, dyes, fragrance, etc.
With that in mind, we compounded a great product after trial and error over one-and-a-half years — the Luxe Serum.
Because that was such a hit, we wanted to add products to our line and developed the Luxe Eye Cream, Luxe Night Cream, and Luxe Retinol 1.5.
Patients have loved the products and have repetitively bought them so we decided to step out and brand, market and sell them on our own, over the counter rather than with a prescription.
Keep an eye out as we have several new products in the works!

Because that was such a hit, we decided to work on an eye cream to fit the concept and after another few months developed the Luxe Eye Cream.
