What ?

The DUOLAB skincare formulator , to transform your skincare capsules into a ready-to-use emulsion in 2 minutes!

For who ?

All skin types.

Why do we love it?

The formulator heats each emulsion to the temperature of the skin to optimize the penetration of the active ingredients. Well-being guaranteed on application!


Here is the essential device to adopt the DUOLAB routine: the formulator (also nicknamed "LAB"). The principle is simple: you insert a moisturizing Base capsule and a concentrated Booster capsule inside. In 2 minutes, you obtain a delicately heated emulsion.

A DUOLAB innovation, the LAB is a patented ally for creating a minute emulsion every day without preservatives, respecting the skin's ecosystem. Freshly emulsified on demand and heated to skin temperature, the active ingredients in the capsules deliver their full power.

The LAB formulator can operate on mains or on battery (with an autonomy of 40 uses). Its compact size is ideal for carrying it everywhere, even on vacation. Its sand color blends elegantly into all bathrooms .

Our advice for using the DUOLAB formulator properly

Press the central button of the device to release its applicator. Open it, then insert the Moisturizing Base into slot 1 and the Concentrated Booster into slot 2. Close the applicator and press its small central white button. Insert it into the formulator by pushing it lightly, until you hear a “beep”. Press the center button of the LAB and wait for 90 seconds. When the padlock button flashes, press it to release the applicator. Press the applicator above the hand to extract the emulsion. Apply the treatment obtained on the face. Remove the empty capsules by pulling on the protruding tab.
