Lucidum8.00 mm

Lucidum. Medical aesthetics, measured in millimeters.

A clinic on Greene Street in SoHo. Before we treat anything, we show you which layer of your skin it reaches.

Every treatment works at a depth. A peel stops a few hundredths of a millimeter down; filler is placed on bone. We begin each consultation by showing you where, so you can judge what is worth doing.

Depths on this site are typical ranges for facial skin. Yours are assessed in person.

Surface to bone is about eight millimeters.

Six layers, seven treatments. The gauge keeps count as you go down.

0.00 to 0.02 mm

Stratum corneum

The surface

Fifteen to twenty rows of flat, finished cells. It is the part you touch, and the only part most creams ever reach.

0.02 to 0.10 mm

Epidermis

Living epidermis

New cells rise from the base of this layer and take about four weeks to reach the surface. The cells that make pigment sit at its floor.

0.10 to 0.50 mm

Dermis papillaris

Upper dermis

Fine collagen and the smallest blood vessels. This is where redness lives, and where the skin gets its supply.

0.50 to 2.00 mm

Dermis reticularis

Deep dermis

Thick bundles of collagen and elastin. Lines that stay when your face is still are set here, and so is most of what we call texture.

2.00 to 6.00 mm

Subcutis

Fat, then muscle

Fat pads give the face its shape. Under them, small muscles fold the skin every time you frown, squint or raise your brows.

6.00 to 8.00 mm

Periosteum

Bone

The structure everything above rests on. With age it recedes a little, and the layers above settle with it.

Six rules we hold to at every depth.

The rest of the clinic is up here, on the third floor.

One floor on Greene Street.

We took the third floor of an 1880s cast-iron building for its tall windows, and kept the room as plain as the building allowed.
