core four
the complete arpy routine in one. all four steps — cleanse, treat, hydrate, nourish — numbered in order, designed to work together. everything your skin needs daily, and nothing it doesn't.
the whole routine.
arpy was built on a simple idea: a routine you can actually keep is a routine that works. core four is all four steps in one box, numbered in order, so there's never a question of what goes where. cleanse, treat, hydrate, nourish — morning and night.
hydrating ceramide cleanser. lifts away the day without stripping the barrier, so skin feels clean and soft rather than tight.
ghk-cu peptide serum. the focused treatment step, built around copper tripeptide-1, coenzyme q10 and niacinamide.
hyaluronic acid gel. a feather-light hydration layer that sits easily under the final step.
nourishing barrier cream. a fragrance-free shea + sunflower finish that seals in the routine and comforts sensitive, reactive skin.
each formula is designed to layer with the next — light to rich, water to cream — so nothing pills or crowds your skin.
four steps, numbered in order. simple enough to keep on the busiest days, which is what makes it work.
core four is $159 — $37 less than buying all four products separately.
how to use
morning and night: 01 cleanse, then 02 treat on clean dry skin, then 03 hydrate, then 04 nourish to finish. two minutes, in order.
what's inside
one of each core product: hydrating ceramide cleanser (125ml), ghk-cu peptide serum (30ml), hyaluronic acid gel (50ml), and nourishing barrier cream (50ml). used twice daily, the routine lasts roughly a month.
who it's for
anyone who wants a complete daily routine without assembling it piece by piece — and a gentler, peptide-led approach suited to normal, combination and sensitive-leaning skin.
