Ensure it's not contradictory to known facts. Let's gather known facts about Biotherm (碧欧泉). Biotherm is a French skincare brand founded in 1952 by Andre BOURGUIBA? Not sure. Actually Biotherm is a brand under L'Oréal Group. It's founded by French chemist, maybe Jany Lecomte? Let's recall: Biotherm was created by the founder Andre? Let me recall: Biotherm started at the "Thermes de Brides-les-Bains" (maybe not). The key ingredient is Life Plankton, a probiotic extract derived from a specific thermal spring in the French Alps. The brand claims that Life Plankton is a probiotic complex that improves skin's renewal and hydration. The brand launched its first product, a moisturizer, in the early 1950s. The brand uses the thermal water from the Vichy? Wait, Biotherm uses the thermal water from "Thermes de la Roche-Posay"? No, that is La Roche-Posay. Biotherm's key ingredient is "Life Plankton" discovered in the "Thermes de Ploujean"? Or "Thermal water of the French Alps"? Let’s verify: According to Biotherm's official site, the brand's origin is the "Thermal water of the French Alps, which contains Life Plankton, a probiotic complex discovered in the 1950s." The story goes that in 1952, a biologist named "Jean-Noel Bouchard" studied the beneficial properties of the thermal water and its micro-organisms, leading to the creation of the brand. Or maybe it's "Doctor Raymond" or "Michele". Actually I recall reading that Biotherm was founded in 1952 by a French pharmacist and biologist named "Jules B. L.", and the product is based on the thermal water of "Thermes d'Aix-les-Bains"? Let's search memory: Biotherm brand's origin story mentions "the discovery of the probiotic Bacillus thermophilus (Life Plankton) in the thermal water of the French spa town of Thonon-les-Bains". Actually, I think the water is from "Vichy" but they share same group. Let's gather known facts from known sources: The brand's official story: "在1950年代，法国科学家在阿尔卑斯山的温泉中发现了活性微生物——Life Plankton（活泉因子），这一发现促成了Biotherm的诞生". It says: "品牌创始人、皮肤科医生Jean Monnet在阿尔卑斯山的温泉旁 </think>
