Smooth, clear skin is a dream when your skin is oily and you have problems with blackheads, spots or uneven skin tone. Laboratoire BIODERMA are recognised experts in skin hygiene, the inventors of micellar water 25 years ago, and they still lead with products dedicated to different skin types with a focus on efficacy and respect for the skin. Now they are going further still, with the concept of active cleansing.

More than a cleanser, Sébium Gel Moussant Actif also provides specific care thanks to AHA and BHA – which is why it’s active cleansing.

Sébium Gel Moussant Actif’s formula both respects acne-prone skin and is effective in treating spots in order to meet skin’s most specific needs, from puberty to adulthood. Because cleansing is the essential first step to healthy skin! With the development of Sébium Gel Moussant Actif, BIODERMA has innovated a formula that is both cleansing and caring.

    At Bioderma, our dermatological hygiene is designed to take care of and preserve skin health, starting at the moment of cleansing. With acne, it has been proven that when an ‘adapted cleanser’ and a moisturiser are both used, patients respect their treatment so that spots finally disappear. Cleansing skin is therefore the first and essential step in getting rid of spots. This is fundamental when we know that half of all acne patients don’t properly follow their treatment.

Active cleansing inspired by ecobiology

A Laboratoire BIODERMA innovation, Sébium Gel Moussant Actif respects the principles behind NAOS’ ecobiological approach, which considers the skin as an ecosystem that is constantly interacting with and adapting to its surrounding environment. 

NAOS’s three ecobiological criteria for active cleansing of oily and acne-prone skin are:

  • Take into account the skin’s ecosystem and respect the skin barrier with a gentle cleansing agent
  • Act on the causes thanks to zinc gluconate which regulates sebum quantity
  • Stimulate the skin’s natural mechanisms with two keratolytic active ingredients, salicylic acid and glycolic acid, which increase cellular renewal in the skin.

The idea behind active cleansing is to launch skin care while cleansing, to prevent and reduce spots more actively. New Sébium Gel Moussant Actif has been formulated for optimal effectiveness, thanks to a unique combination of keratolytic active ingredients.

Sébium Gel Moussant Actif ensures perfect balance between efficacy and tolerance.

  1. Gentle cleanser > Cleanses skin without weakening it, thanks to a soap-free, sulphate-free base that respects the skin barrier.
  2. Active cleanser > Deep cleanses the skin above and below the surface, reducing spots thanks to a keratolytic action that removes dead skin cells and increases cell turnover.
salicylic & glycolic acid

A micro-peeling effect, both on the surface and deep into the pores

Acne-prone skin has a tendency to thicken as a defence mechanism, building up dead cells, sebum and other elements that collect on the skin’s surface and block pores. As a purifying cleanser, Sébium Gel Moussant Actif contains a combination of AHA (alphahydroxy acid) and BHA (betahydroxy acid), known for their complementary keratylotic action, one on the surface, the other deep down. Keratolytic action refers to the ability to smooth skin texture by removing dead skin and stimulating cell renewal.

  • Salicylic acid (BHA) is an ideal active ingredient for oily and acne-prone skin as it is lipophilic, giving it the ability to dissolve oil. Able to break the ties between dead cells, it eliminates them from the skin’s surface. This exfoliating action helps in unclogging the pores, helping to make them look smaller. It also prevents comedones from forming and spots from becoming inflamed and red1 thanks to its anti-inflammatory and antibacterial benefits.
  • Glycolic acid (AHA) penetrates deeply thanks to its small molecular size. Glycolic acid is hydrophilic, meaning it has a strong affinity to water and is able to reach where salicylic acid cannot. A powerful active ingredient, it eliminates dead and dehydrated skin cells and accelerates the desquamation process, creating a ‘renewed skin’ effect. Thanks to this exfoliating action, skin becomes bright and smooth. For it to realise all of its potential as an active ingredient, there needs to be kept in an environment whose pH is sufficiently acidic.


Thanks to the AHA-BHA pair, traditionally used by doctors for peelings, Sébium Gel Moussant Actif produces great results on acne-prone skin.

  • Pores are unclogged
  • Spots are reduced

Whether it's used as an anti-imperfections treatment or as twice-weekly preventative cleanser, Sébium Gel Moussant Actif activates cellular renewal, gets rid of existing spots andcontributes to preventing future breakouts.

An acid pH at 4.5 to optimise the keratolytic effect

Glycolic acid needs a more acidic environment to be effective. Sébium Gel Moussant Actif has therefore been formulated with a slightly acidic pH to increase the AHA complex’s keratolytic efficacy on oily and acne-prone skin. With healthy skin pH sitting between 4.5 - 5.5, this acidic pH respects the skin barrier and doesn't strip away essential oils.

A gentle formula that respects the skin barrier

Cleansing without stripping is essential for oily and acne-prone skin. Sébium Gel Moussant Actif meets the challenge thanks to its gentle washing base that respects oily and acne-prone skin’s balance.

Good to know

"Acne cleanser" can bring to mind skin drying out and being irritated. There is no risk of that with Sébium Gel Moussant Actif with each keratolytic active ingredient being at its optimal concentration, enough to unclog pores and produce results with blackheads and spots. Compared to mechanical scrubs with beads, the acidic exfoliation with keratolytic ingredients doesn’t irritate the skin due to rubbing2. We recommend complementing Sébium Gel Moussant Actif with Sébium Sensitive for acne-prone skin or Sébium Mat Control for combination, oily skin looking to prevent spots.
