Made to work together
Within the Biologique Recherche methodology, cleansing is followed by the Lotion P50 selected for your Skin Instant, then the serums, creams and finishing products selected for your current Skin Instant. A cleanser does not need to do the job of every product that follows it: when blemishes and excess sebum are part of the picture, a targeted serum such as Complexe Iribiol can take over after the Lotion P50.
Your routine
Biologique Recherche’s exfoliating, purifying and balancing lotion for seborrheic Skin Instants. The first step after cleansing.
Your routine
When blemishes come with excess sebum, Complexe Iribiol picks up where Lait S.R. leaves off: the milk cleanses and removes excess surface sebum, while the serum targets oily, blemish-prone Skin Instants.
Worth knowing
A closer look at your skin, your routine and what goes into the formula.
Biologique Recherche Lait S.R. is a lightweight purifying cleansing milk designed specifically for combination and oily Skin Instants experiencing excess sebum, shine or congestion.
Its fresh, fluid texture removes makeup, impurities and excess surface oil without leaving a heavy or greasy film behind. Rather than aggressively stripping oil from the skin, Lait S.R. cleanses while helping preserve the skin's natural balance and protective barrier.
Sebum plays an important role in the skin's protective hydrolipidic film, so the goal is not to remove all oil: it is to remove excess sebum, makeup, sunscreen and environmental debris while respecting the skin underneath. That tight, squeaky-clean feeling is not necessarily a sign of a better cleanse.
After cleansing, skin feels fresh, comfortable and clean, with a more balanced, shine-free appearance. It is particularly interesting for anyone who wants the comfort of a cleansing milk but finds traditional rich cleansers too heavy for combination or oil-prone skin.
Lait S.R. is one of our favourite cleanser conversations, because many clients with oilier skin think they need something foaming, aggressive or drying. Usually, we want the opposite. We reach for it when someone's T-zone gets oily quickly, when their skin feels congested but every cleanser leaves them tight, or when they loved a milk cleanser but need something lighter. We especially like it as the foundation of a Biologique Recherche routine for combination or blemish-prone Skin Instants, because cleansing should prepare the skin, not punish it.
Combination and oily skin
If your skin feels tight after cleansing, don't take it as proof the cleanser is working: tell your esthetician so we can reassess your routine.

Yes. It is particularly suited to combination and oil-prone Skin Instants where excess sebum, shine or congestion are concerns.
It can be particularly appropriate when blemishes occur alongside excess sebum and congestion. Its primary role is cleansing and rebalancing; active imperfections may call for additional targeted products in the routine.
No cleanser can permanently shrink or close pores. By thoroughly removing excess sebum and impurities, Lait S.R. can help support a cleaner, more refined-looking complexion. If visible pore size is your main concern, a targeted serum such as Dermopore may be more appropriate.
It is designed to remove excess sebum without disrupting the skin's natural balance. If your skin consistently feels tight or uncomfortable after cleansing, that is something we would want to reassess.
It is not the cleanser Biologique Recherche specifically recommends for fragile or reactive Skin Instants. If sensitivity or barrier fragility is your main concern, Lait Dermo-S may be the more targeted choice.
Biologique Recherche recommends removing it with wet cotton pads and repeating the application until impurities are completely removed.
At Loshen & Crem, we want to ensure you have the best possible experience with Biologique Recherche.
