Tonic. For years we&#8217;ve been told that it&#8217;s &#8220;just refreshing water.&#8221; From the point of view of biochemistry and dermatology, skipping this step is the shortest way to disruption of the hydrolipid barrier and proliferation of pathogens.   <\/strong><\/p>\n\n<h4 style=\"color: #154734; margin-top: 30px; margin-bottom: 15px; font-size: 18px;\">Acid coat &#8211; your invisible shield<\/h4>\nYour skin has a natural protective mantle, whose pH is slightly acidic and ranges from 4.5 &#8211; 5.5. This environment is not accidental. The acidic reaction is a shield. It keeps the good bacteria (your microbiome) in check and at the same time is deadly to intruders.   \n\n<p style=\"margin-top: 15px;\">What happens when you wash your face with tap water and a random gel? The pH of your skin increases dramatically, becoming alkaline. <\/p>\n\n<h4 style=\"color: #154734; margin-top: 30px; margin-bottom: 15px; font-size: 18px;\">Why do pathogens love rules?<\/h4>\nAn alkaline environment is a veritable paradise for microorganisms that cause skin diseases.\n<ul style=\"padding-left: 20px; margin-bottom: 25px; margin-top: 15px;\">\n \t<li style=\"margin-bottom: 10px;\">The <em>Cutibacterium acnes<\/em> bacteria, responsible for acne vulgaris, begin to multiply at a rapid pace.<\/li>\n \t<li><em>Staphylococcus aureus<\/em>, which so severely exacerbates the symptoms of Atopic Dermatitis, colonizes the dry, alkaline environment unhindered.<\/li>\n<\/ul>\n\n<h4 style=\"color: #154734; margin-top: 30px; margin-bottom: 15px; font-size: 18px;\">The task of a skincare tonic: Instant reset<\/h4>\nThe skin can restore its acidic pH on its own, but it takes up to several hours. During this time it is vulnerable, and the creams applied in the meantime cannot take full effect (their active ingredients are often stable in an acidic environment). \n\n<p style=\"margin-top: 15px;\">That&#8217;s why we at MCS Laboratory confidently recommend the Care Tonic as the perfect complement to the treatments in our lines for AD, Psoriasis and Rosacea. The tonic is not a fad. It&#8217;s a buckle that connects cleansing (such as our gentle Foaming Cleanser) with skin care. Applied to the skin, it &#8220;resets&#8221; the environment to an ideal level in seconds, quenching inflammation and preparing the ground for the reception of a day or night cream.   <\/p>\n\n<p style=\"padding: 15px; background-color: #fafafa; border-left: 4px solid #154734; border-radius: 4px; font-style: italic;\"><strong>Summary:<\/strong> Don&#8217;t condemn your protective barrier to a several-hour battle.
