With age or exposure to external aggressors, the water content in the superficial layers of the epidermis gradually decreases, accentuating skin laxity and dullness. Hyaluronic acid is the most well-documented hygrophilic active ingredient for maintaining skin hydration levels — it has an exceptional water retention capacity and remains a reference active ingredient in dermatological and cosmetological care.\u003c\/p\u003e\n\u003cp\u003eCos De Baha's Serum H stands out for the purity and clarity of its formula. With only three ingredients — Aqua, 1,2-Hexanediol, Sodium Hyaluronate — it contains no sensitizing active ingredients, no fragrance, and no strong alcohol. The Sodium Hyaluronate used is of high molecular weight (HMW, 1,500 kDa according to the manufacturer): it acts on the surface to form a moisturizing film and reduce transepidermal water loss. The 1% concentration (10,000 ppm) is significant — well-formulated HA serums are between 0.1% and 2%. The pH of 6.5 is compatible with all routine active ingredients.\u003c\/p\u003e\n\u003cp\u003eApply 1 to 2 drops to the face and neck after cleansing and toning, morning and evening. The serum can also be applied around the eyes. Its absorption is immediate, with no residual film. It can be layered with other active serums applied beforehand and should always be applied before moisturizer to optimize water retention.\u003c\/p\u003e\n\u003cp\u003eNo special precautions are needed. This serum is compatible with all active ingredients in the Cos De Baha range — it can advantageously be applied before exfoliating serums (AHA, BHA), depigmenting agents, or retinols (L1, L2) to buffer their irritating potential. Compatible with pregnancy, breastfeeding, and the most sensitive skin types.\u003c\/p\u003e\n\u003cp\u003eIn your routine, it integrates at the serum step, after toner and before cream. For very dry skin or skin exposed to air conditioning and cold, it can be applied morning and evening in a thin layer, or used as a boost by incorporating it into your moisturizer.\u003c\/p\u003e","brand":"Cos De Baha","offers":[{"title":"Default Title","offer_id":53898326671697,"sku":"PD-0481","price":12.74,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1032\/7094\/1009\/files\/cos-de-baha-h-serum-hyaluronic-acid-pd-0481-1-hd.jpg?v=1788396165","url":"https:\/\/paradermia.com\/en\/products\/cos-de-baha-h-serum-hyaluronic-acid-pd-0481","provider":"Paradermia","version":"1.0","type":"link"}
