Absorption

We focus on absorption.

Most of what you apply stops at the stratum corneum. re:tones makes the device that opens the channel and the ampoule formulated for that channel. One system.

Our Science

The stratum corneum is a filter, not a door.

01 — The problem

What you apply to the surface mostly stays on the surface.

The stratum corneum exists to keep foreign matter out. The better it does its job, the less gets in.

02 — The mechanism

The device opens the channel. You choose the depth.

The MTS device creates temporary micro-channels. Depth is adjustable from 0.5 mm to 1.5 mm across five settings.

03 — The consequence

Which is why the ampoule has to be a sealed vial.

This formula meets a barrier that is open. It has to be sterile until opened, and finished once it is.

Needle Gauge — 8 µm

An ultra-fine needle you cannot see.

Our own needle, finer than a human hair, passes through skin and delivers actives directly.

Balloon Test

It passes through without bursting.

Where a conventional device only meets the surface, re:tones MTS passes through the membrane and delivers inside.

Our Research

We treat absorption as a science.

Most skincare never gets deep enough to do the work it promises. That is the problem we chose to study, and the reason re:tones makes both halves of the system.

The problem nobody was solving

01

The problem nobody was solving

Most skincare evaporates off the surface or stalls at the stratum corneum. The formula was never the weak link — the route in was. So the useful ingredients never reach the layers where skin problems actually begin.

The formula was never the weak link. The route in was.

So we studied the pathway instead

02

So we studied the pathway instead

Our R&D team in South Korea works on one question: how do you get an active past the barrier and into the layers that matter. That research produced both halves of the system — a device that opens a temporary channel, and ampoules formulated for that channel.

Concentrations that do something

03

Concentrations that do something

Most labels carry actives at levels too low to matter — a name on a box, not a dose. We publish the actual formulation percentage of every active, because a number you can check is worth more than one you cannot.

Sourced at origin, made in Korea

Our raw materials come direct from source in South Korea, and every ampoule is manufactured here by BLUWHA. Shorter chain, fewer hands, and a formulation we control end to end.

One System

Not four products. One delivery system.

The device opens the road. The ampoule travels it. Neither is complete on its own.

Form Follows The Claim

The glass vial is not a preference. It is a consequence.

Immediately after treatment the skin barrier is briefly open. A formula meeting that skin is held to a different standard.

It has to be sterile until opened, and finished once it is. Pumps and droppers meet air and fingers on every use. They do not meet that condition.

So the format is a crimp-sealed medical glass vial. The rubber septum and flip-off cap were decided the same way.

The form did not come first with the claim following. The claim came first, and the form followed.

How To Use

Device and ampoule, in that order.

01

Cleanse, then dry the skin completely

Any moisture left and the device slips. Do not apply anything else yet.

02

Fit a fresh cartridge tip

Tips are single-use. Never reused.

03

Load the ampoule and set the depth

With the paired ampoule loaded it dispenses automatically as you work. If it is your first time, start at 0.5 mm.

04

Work section by section at an even pace

Keep moving; do not dwell on one spot.

05

Apply what is left and let the skin settle

For 24 hours afterwards, focus on sun protection and calming the skin.
