Which areas is the two-phase fluid intended for?
For the face, body and scalp, especially rough and stressed areas of skin.
Why do I need to shake the fluid?
DOUBLE combines two skincare phases. Shaking vigorously mixes them immediately before use, so you can spread the hydrating phase and lipid phase together on your skin.
Can I use it daily and with other products?
Yes. Adapt its use to your skincare needs. You can also mix a few drops with body lotion in your palm.
How do I apply DOUBLE for scalp care?
Part your hair and apply a few drops directly to the skin. Gently massage with your fingertips.
Which cap should I open on DOUBLE CONCENTRATE?
Shake the closed bottle vigorously before each use. Then unscrew only the small cap on the dispensing tip. Leave the large bottle cap in place. Dispense the fluid through the tip.
How much two-phase fluid should I apply?
After shaking, dispense a few drops through the tip. Spread them over the area you want to care for and massage gently. DOUBLE is intended for the face, body and scalp; you can also apply it to individual dry areas. Our guide to serum and two-phase fluid explains their different roles in a routine.
What does DOUBLE smell like without added perfume?
DOUBLE has a scent of its own from its ingredients. We do not add perfume.

My husband and I both use the fluid. He applies it after shaving, while I tend to use it in the evening on my face and neck.

For me, this is the extra care I use on days when my regular cream is not enough. It feels intensively nourishing.

Für mich ist das die Extrapflege an Tagen, wenn meine normale Creme nicht ausreicht. Es fühlt sich intensiv pflegend an.

My skin reacts quickly to fragrances, so I am always careful with new skincare products. I introduced Double Concentrate gradually and tolerated it well.

Meine Haut reagiert schnell auf Duftstoffe, deshalb bin ich bei neuer Pflege immer vorsichtig. Double Concentrate habe ich langsam eingeführt und gut vertragen.
Jasmin B. (Confirmed customer experience) –

I was mainly curious about it because of my dry scalp. The fluid can be applied precisely and sparingly, and it does not weigh my hair down as long as I really use only a small amount.

Ich war vor allem wegen meiner trockenen Kopfhaut neugierig. Das Fluid lässt sich gezielt und sparsam auftragen und beschwert bei mir nicht, wenn ich wirklich nur wenig nehme.

My skin feels particularly tight after showering. A few drops on slightly damp skin are enough for me. And I like the slightly sweet scent of calendula.

Meine Haut spannt besonders nach dem Duschen. Ein paar Tropfen auf die noch leicht feuchte Haut reichen bei mir schon aus. Und ich mag den leicht süßlichen Duft von Calendula.

I really like the fluid. You really do have to shake it thoroughly before use, which took me a little while to get used to.

Das Fluid gefällt mir sehr gut. Man muss vor der Anwendung wirklich ordentlich schütteln, daran musste ich mich erst gewöhnen.
Julia (Confirmed product test) –
Translated from the German original.
I wanted the fluid for my face because I constantly had dry patches. My skin feels much better and less tight. I also apply it to dry areas on my body and occasionally to my scalp.

Ich wollte das Fluid fürs Gesicht, weil ich ständig trockene Stellen hatte. Die Haut fühlt sich viel besser an und spannt weniger. Ich gebe es auch auf trockene Stellen am Körper und gelegentlich auf die Kopfhaut.
Anja D. (Confirmed customer experience) –

I mainly use the fluid on dry areas of my face and neck. After shaking it, it spreads easily and feels rich without being unpleasantly sticky.

Ich benutze das Fluid hauptsächlich an trockenen Stellen an Gesicht und Hals. Nach dem Schütteln lässt es sich gut verteilen und fühlt sich reichhaltig an, ohne unangenehm zu kleben.
