Overview

• Ultimate A Gold is now available direct from ESK’s website for $100, marking Blair’s first co-developed skincare launch.
• The formula uses 0.1% retinal, a higher concentration than ESK’s original 0.06% Ultimate A, to accelerate results while aiming to limit irritation.
• Supporting ingredients include niacinamide, ceramides, squalane, polyhydroxy acids, hyaluronic acid, and 4‑n‑butylresorcinol to bolster the barrier and target hyperpigmentation.
• Blair was deeply involved in development and calls the cream her hero product, with ESK positioning it for reactive and mature skin.
• ESK, co-founded by Dr. Ginni Mansberg and Daniel Rubinstein, frames the launch as the latest step in a roughly 12‑year evolution of its evidence-based retinal formulas.
