Detox-sunscree-microderma-wha?

Oh. Your skin care regimen is in retrograde.

Though you appear to be spinning backward, a trip to Bluemercury Apothecary and Spa — the UWS’s new deluxe beauty emporium — can reverse the motion.

The Georgetown-based brand offers niche toiletries to those who like a bit of advice with their Serge Lutens atomizing samples. (“Mario Badescu’s drying potion for blemishes is a must”; “C E ferulic acid is an antioxidant staple”).

Cult brands Jurlique, Darphin, Ren, Bobbi Brown, and Remède mingle neatly with Fekkai, Bumble and Bumble, Tocca, and Fresh.

They’re adding finishing touches to the two treatment rooms, where luxe but expeditious facials, glycolic peels, brow styling, waxing, and massage will go down (they’ve even relocated their best D.C. masseuse for the occasion).

Grab what you need or stay and play at your leisure.

Without any cosmic trickiness.

Bluemercury Apothecary and Spa, 2305 Broadway, between 83rd and 84th Streets (212-799-0500 or bluemercury.com).
