More critically, it also contains camphor and thyme essential oil, which are typically avoided during pregnancy. Additionally, several natural fragrance components (such as coumarin and oakmoss extract) are best avoided when pregnant. Always consult your OB\/GYN or dermatologist before continuing use of this product during pregnancy.

Avoid using P50 on the same evening as a retinoid until your skin has acclimated to both products. With vitamin C: Generally fine to layer, but introduce gradually. Vitamin C serums can go on after P50 in the same routine. If you experience irritation, separate them to AM (vitamin C) and PM (P50). With other AHAs\/BHAs: Avoid layering P50 with other dedicated acid exfoliants (glycolic acid serums, additional BHA toners) as this significantly increases the risk of over-exfoliation and barrier damage.\"\n          }\n        },\n        {\n          \"@type\": \"Question\",\n          \"name\": \"What skin type is Lotion P50 best for?\",\n          \"acceptedAnswer\": {\n            \"@type\": \"Answer\",\n            \"text\": \"Lotion P50 (the original formula) is best suited to oily, combination, normal, and resilient skin types.

The formula contains salicylic acid (BHA), which at high systemic doses has been associated with concerns during pregnancy, though topical use at low concentrations is considered low risk. More critically, it also contains camphor and thyme essential oil, which are typically avoided during pregnancy. Additionally, several natural fragrance components (such as coumarin and oakmoss extract) are best avoided when pregnant. Always consult your OB\/GYN or dermatologist before continuing use of this product during pregnancy. If you're looking for a safer pregnancy alternative, consider a simple lactic acid toner without BHA or essential oils.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq2\"\u003e\n\u003clabel for=\"faq2\"\u003eIs Biologique Recherche Lotion P50 fungal acne (malassezia) safe?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eYes — Lotion P50 is considered fungal acne safe. The formula contains no fatty acids, polysorbates, esters, or fermented ingredients that are known to feed Malassezia yeast. In fact, the formula contains actives (salicylic acid, sulfur, and thyme oil) that have documented antifungal properties. This makes P50 a particularly good choice for those who struggle with fungal acne or pityrosporum folliculitis alongside regular comedonal acne.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq3\"\u003e\n\u003clabel for=\"faq3\"\u003eCan I use Lotion P50 with retinol, vitamin C, AHA\/BHA?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eWith retinol: Yes, but carefully. Many estheticians recommend using P50 in the morning and retinol\/retinoids at night to avoid over-exfoliating. If you use prescription tretinoin, do not use P50 simultaneously without guidance from a professional — the combination can cause severe irritation. Avoid using P50 on the same evening as a retinoid until your skin has acclimated to both products. With vitamin C: Generally fine to layer, but introduce gradually. Vitamin C serums can go on after P50 in the same routine. If you experience irritation, separate them to AM (vitamin C) and PM (P50). With other AHAs\/BHAs: Avoid layering P50 with other dedicated acid exfoliants (glycolic acid serums, additional BHA toners) as this significantly increases the risk of over-exfoliation and barrier damage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq4\"\u003e\n\u003clabel for=\"faq4\"\u003eWhat skin type is Lotion P50 best for?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eLotion P50 (the original formula) is best suited to oily, combination, normal, and resilient skin types. It delivers particularly impressive results for acne-prone and congested skin due to the BHA\/sulfur\/botanical complex. For dry skin, Lotion P50V (the vitamin-enriched version) is a better choice. For sensitive skin, Lotion P50W (the phenol-free, gentler version) is recommended. If you're completely new to chemical exfoliants, all versions of P50 should be introduced slowly — start on a damp cotton pad to buffer intensity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq5\"\u003e\n\u003clabel for=\"faq5\"\u003eHow long until I see results from Lotion P50?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eMost users notice a difference in radiance and skin texture within the first 1–2 weeks of consistent use. The name \"P50\" is actually derived from the product's philosophy: \"P\" for Peeling and \"50\" for the 50 days (two 25-day epidermal cycles) required to achieve the first level of true epidermal reconditioning. Visible pore refinement, improved texture, and reduced breakouts are typically evident within 4–6 weeks. The most significant long-term transformation — clearer, more even, glowing skin — develops over 3–6 months of daily use. Results are highly dependent on consistent daily application.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq6\"\u003e\n\u003clabel for=\"faq6\"\u003eWhere does Lotion P50 go in my skincare routine?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eLotion P50 is used immediately after cleansing, as the first active step in your routine. This is important: it exfoliates, purifies, and rebalances the skin's pH, priming it to absorb everything that follows more effectively. After P50, apply your serums (vitamin C, hyaluronic acid, targeted treatments), then eye cream, followed by moisturizer. In the morning, always finish with a broad-spectrum SPF 30+ sunscreen. In the evening, finish with your moisturizer and any overnight treatments. Do not rinse off after application.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq7\"\u003e\n\u003clabel for=\"faq7\"\u003eIs Lotion P50 comedogenic \/ will it clog pores?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eNo — Lotion P50 is non-comedogenic with a rating of 1 out of 5. The formula is entirely water-based with no occlusive oils or waxes that could block pores. In fact, the opposite is true: the salicylic acid and botanical extracts actively work to unclog existing pores and prevent new congestion from forming. The primary humectants — glycerin (rating 0) and propylene glycol (rating 0) — are both non-comedogenic. P50 is an appropriate choice for acne-prone skin concerned about pore-clogging ingredients.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pp-faq-item\"\u003e\n\u003cinput type=\"checkbox\" id=\"faq8\"\u003e\n\u003clabel for=\"faq8\"\u003eHow long does Lotion P50 last after opening?\u003c\/label\u003e\n\u003cdiv class=\"pp-faq-answer\"\u003e\n\u003cp\u003eLotion P50 has a Period After Opening (PAO) of 12 months.

Its combination of five acids (AHA, BHA, and PHA), meaningful niacinamide, sulfur, and a proprietary botanical purifying complex delivers a multi-pathway approach to skin renewal that no single-acid toner can replicate. The results speak for themselves: refined pores, dramatically improved texture, reduced breakouts, and a lasting luminosity that builds over weeks and months. The premium price and strong scent are real considerations, but for those who commit to the product and its method, Lotion P50 consistently delivers transformative, esthetician-grade results at home. It is not suitable for pregnancy, extremely sensitive skin, or fragrance-reactive users without careful evaluation, but for everyone else — this is one of the rare products that truly lives up to the hype.\n\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cbutton class=\"pp-back-to-top\" aria-label=\"Back to top\" type=\"button\" style=\"position:fixed;bottom:24px;right:24px;width:44px;height:44px;border-radius:50%;background:var(--pp-accent);color:#fff;border:none;display:none;cursor:pointer;z-index:50;box-shadow:0 4px 16px rgba(13,31,45,0.2)\"\u003e↑\u003c\/button\u003e\n  \u003cscript\u003e\n  (function () {\n    var btt = document.querySelector('.pp-back-to-top');\n    if (!btt) return;\n    var ticking = false;\n    function onScroll () {\n      if (!ticking) {\n        requestAnimationFrame(function () {\n          btt.style.display = window.scrollY \u003e 600 ?
