Formulated to purify, rebalance, and strengthen the skin, it dissolves dead cell buildup, restores pH equilibrium, and prepares the complexion to absorb what follows. This is the modern formulation developed after the original phenol-based Lotion P50 1970 was discontinued, delivering the same results with a safer, more compatible profile.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNot sure this is your P50? \u003ca href=\"\/pages\/lotion-p50-layering-guide\"\u003eCompare all six in our Lotion P50 Guide →\u003c\/a\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003c!-- split --\u003e\n\u003cul class=\"tabs cc-tabs\" role=\"tablist\"\u003e\n\u003cli role=\"presentation\"\u003e\u003ca class=\"active\" role=\"tab\" href=\"#tab1\"\u003eKey Benefits\u003c\/a\u003e\u003c\/li\u003e\n\u003cli role=\"presentation\"\u003e\u003ca role=\"tab\" href=\"#tab2\"\u003eHow to Use\u003c\/a\u003e\u003c\/li\u003e\n\u003cli role=\"presentation\"\u003e\u003ca role=\"tab\" href=\"#tab3\"\u003eActive Ingredients\u003c\/a\u003e\u003c\/li\u003e\n\u003cli role=\"presentation\"\u003e\u003ca role=\"tab\" href=\"#tab4\"\u003eFAQ\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul class=\"tabs-content\"\u003e\n\u003c!-- TAB 1: Key Benefits --\u003e\n\u003cli id=\"tab1\" class=\"active\" role=\"tabpanel\"\u003e\n\u003cp\u003eBiologique Recherche Lotion P50 exfoliates, rebalances, and conditions the skin's surface with daily use.

Lotion P50W is the gentlest version in the family, formulated for thin or sensitive skin. It pairs milder exfoliation with soothing ingredients like Arnica and Urea to minimize the risk of irritation.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between Lotion P50 and Lotion P50 1970?\u003c\/h3\u003e\n\u003cp\u003eLotion P50 1970 was the original phenol-based formula. It has since been discontinued. The current Lotion P50 is the modern reformulation — developed to deliver comparable exfoliating and rebalancing results without phenol, making it safe for regular daily use.\u003c\/p\u003e\n\u003ch3\u003eCan I use Lotion P50 every day?\u003c\/h3\u003e\n\u003cp\u003eYes, Lotion P50 is designed for daily use. If you are new to exfoliating acids, begin every other day and increase frequency gradually as your skin adjusts. Most clients build to twice-daily use — morning and evening — over time.\u003c\/p\u003e\n\u003ch3\u003eWhere does Lotion P50 fit in my skincare routine?\u003c\/h3\u003e\n\u003cp\u003eLotion P50 is applied after cleansing, before serums and creams. Press it gently into the face, neck, and décolleté using a cotton pad — do not rub. It prepares the skin to absorb everything that follows more effectively.\u003c\/p\u003e\n\u003ch3\u003eIs Lotion P50 suitable for acne-prone skin?\u003c\/h3\u003e\n\u003cp\u003eYes. The combination of Salicylic Acid, Sulfur, and Niacinamide makes Lotion P50 well-suited to skin prone to congestion and breakouts. It regulates sebum, unclogs pores, and reduces the buildup that leads to blemishes with consistent use.\u003c\/p\u003e\n\u003ch3\u003eWhy does Lotion P50 have a strong smell?\u003c\/h3\u003e\n\u003cp\u003eThe scent comes from active ingredients including cider vinegar, sulfur, and botanical extracts — all functional components of the formula. The smell dissipates quickly after application and is not an indication of irritation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Biologique Recherche","offers":[{"title":"1.7 fl oz.","offer_id":32152259362881,"sku":"LOP550","price":45.0,"currency_code":"USD","in_stock":true},{"title":"5.1 fl oz.","offer_id":32060691218497,"sku":"LOP5150","price":100.0,"currency_code":"USD","in_stock":true},{"title":"8.4 fl oz.","offer_id":8108433153,"sku":"LOP5250","price":155.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0112\/9612\/files\/lotion-p50-for-normal-skinbiologique-rechercheaida-bicaj-811797.jpg?v=1712978138","url":"https:\/\/aidabicaj.com\/products\/biologique-recherche-lotion-p50","provider":"Aida Bicaj ","version":"1.0","type":"link"}
