Description
√ Sensitive skin that reacts excessively to even mild stimulation
√ No matter how much you remove dead skin cells, the skin bumpy
√ Skin with a lot of oil but also severe dryness
√ Corneous skin that becomes dry immediately after washing the face
The problem is, fatty acids that resemble sebum
whiteheads trouble is the cause of uneven skin texture, and the bacteria that cause it grow by absorbing certain fatty acids in cosmetics that are similar to sebum.
Therefore, a single fatty acid ingredient hidden in all ingredients can neutralize the effectiveness of all cosmetics you are using.
Fatty acid ingredients that help the growth of some skin flora (trouble-causing bacteria) have been completely removed from all ingredients in the product.
POINT || Minimize irritating ingredients for troubled skin
By removing all ingredients that may irritate only some skin types, we provide a mild solution optimized for troubled skin with only the minimum necessary ingredients.
POINT ||| Minimize skin flora activity by soothing the skin
Quickly protects skin irritated by external stimulation or washing with appropriate ingredients to minimize activation of skin flora.
Purpose 1 : Protect skin barrier
After washing your face, absorb the toner first.
√ Be sure not to strain the skin barrier! Tap lightly to absorb.
√ We do not recommend using the wiping method.
Purpose 2 : Oil and water balance
Please use an appropriate amount to prevent oil from rising.
√ If you only provide moisture (toner/cream), the oil-water balance may be disrupted.
Please note that additional oil moisturizing is necessary in the long run.
√ For dry skin lacking oil, we recommend using oils without fatty acids rather than toner.
(100% squalane, petrolatum, lanolin alcohol, etc.)
*Be careful how you use it!
La Théorie Toner is based on skin barrier protection and adds sufficient moisture.
This product aims to soothe skin problems. When using the product, we recommend that you gently pat the product on your entire face to allow it to be absorbed, rather than using the wiping method, which can strain the barrier.

Recentemente, testei o La Théorie Toner Soothing Treatment e foi uma surpresa maravilhosa! Minhas preocupações com a textura irregular da pele pareciam sumir como mágica. Ao contrário de outros produtos que só intensificam as imperfeições, este toner age delicadamente nas camadas superficiais sem causar irritação – algo tão raro quando lidamos com cuidados para peles sensíveis. A leveza na fórmula também trouxe um alívio significativo no excesso de oleosidade por ter apenas “0% ácido graxo”, contrastando muito bem com minha rotina cheia de ingredientes pesados utilizados em tentativas anteriores.
Clara Amato from Buenos Aires, Argentina –
Initially, I was hesitant about the La Théorie Toner Soothing Treatment; how could a toner so delicately balanced tackle my stubborn skin? Born from skepticism born of numerous failed attempts with skincare concoctions promising miracles and delivering nothing but frustration, this product lured me in like a siren’s call. But lo and behold! With each application, I felt my oily patches surrendering to comfort while those dry areas soaked in moisture—a harmonious reunion for which I’d yearned. Just under two weeks into this journey, I’ve noticed distinct improvement in texture—the roughness lessens as if it knows its time is over. Curious indeed—this nifty little bottle does hold remarkable potential!
