It is the first choice for patients with no acne and low sebum secretion. <\/li>\n\n\n\n<li><strong>Zeroid Intensive Cream MD<\/strong> \u2014 Provides the next highest level of hydration after the Rich Cream and is primarily used for the <strong>face<\/strong>.<\/li>\n\n\n\n<li><strong>Zeroid Intensive Lotion MD<\/strong> \u2014 A lighter formulation than the cream, making it ideal for the <strong>body<\/strong> as it spreads easily over large areas. It is also less burdensome for patients with high sebum secretion. <\/li>\n\n\n\n<li><strong>Zeroid Rootheal Moisturizer MD<\/strong> \u2014 Suitable for those with seborrheic dermatitis on the <strong>scalp<\/strong>. Since oily moisturizers can feed Malassezia and worsen seborrheic dermatitis, a low-oil lotion type like Rootheal is more appropriate. For more details, please refer to the <a href=\"https:\/\/miragen.clinic\/en\/seborrheic-dermatitis\/\" data-type=\"page\" data-id=\"4062\">Seborrheic Dermatitis Guide<\/a> page.  <\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Based on patch tests conducted at our clinic on 113 dermatitis patients using these four products, <strong>Zeroid Intensive Rich Cream MD showed the lowest percentage of irritation, while Rootheal Moisturizer MD showed the highest.<\/strong> The trend of stronger moisturizing power correlating with lower irritation was common across several brands. <strong>It is suspected that thinner formulations have higher preservative content due to their higher water ratio.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is important to note that even for Zeroid Intensive Rich Cream MD, our data shows that over 25% of patients experienced an irritation response during patch testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If we also consider cases where acne is worsened by clogged pores due to high moisturizing power, the percentage of patients who feel the product is &#8220;not a good fit&#8221; would be even higher.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In short, even the most excellent moisturizer will not suit everyone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sec-2\">Why Moisturizers Can Irritate Dermatitis Patients<\/h2>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">So why do moisturizers become a problem? There is no doubt that moisturizers protect the skin. A Cochrane systematic review also showed that atopic dermatitis patients who consistently used moisturizers saw significant benefits in terms of recurrence rates and steroid usage.<sup><a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28432721\/\" target=\"_blank\" rel=\"noopener\">1<\/a><\/sup>  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the situation is different for patients with a weakened skin barrier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When the barrier is strong, the moisturizer stays on the surface to act as a protective shield, but <strong>when the barrier is compromised, it can seep into the skin and trigger inflammation.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, dermatitis patients need a <strong>moisturizer that does not cause issues even if small amounts penetrate the skin.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img decoding=\"async\" src=\"https:\/\/miragen.clinic\/wp-content\/uploads\/2026\/06\/moisturizer-irritation-on-damaged-barrier-main-EN.png\" alt=\"Infographic explaining how applying an unsuitable moisturizer to damaged skin causes preservatives and emulsifiers to excessively penetrate through cracks in the brick wall structure, worsening irritation and inflammation\" class=\"wp-image-4533\" title=\"Difference in Moisturizer Action: Normal vs. Damaged Skin\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sec-3\">Why Ingredient Analysis Is Not the Answer<\/h2>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">Many dermatitis patients analyze ingredient lists to find such moisturizers, but this approach has limitations for the following reasons.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First, <strong>ingredients do not work in isolation.<\/strong> Even with the same ingredient, skin reactions vary depending on concentration, formulation, pH, and the combination of auxiliary ingredients. For ceramides, the ratio between lipids is more important for barrier recovery than their mere presence.<sup><a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/35065300\/\" target=\"_blank\" rel=\"noopener\">2<\/a><\/sup> <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second, <strong>there are differences in purification levels among raw material suppliers.<\/strong> Even with the same INCI name, reactions can vary if the types and amounts of impurities differ. Therefore, <strong>even if the ingredient lists appear identical, the skin&#8217;s reaction may not be the same.<\/strong> <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Third, <strong>individual responses to the same ingredient vary.<\/strong> For example, atopic dermatitis patients exhibit significantly higher delayed allergic reactions to preservatives than the general population.<sup><a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24220722\/\" target=\"_blank\" rel=\"noopener\">3<\/a><\/sup> No amount of ingredient analysis can account for these individual sensitivity differences.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Consequently, the only way to know if Zeroid MD or any other moisturizer truly suits you is to actually apply it to the affected area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sec-4\">How to Reduce Trial and Error<\/h2>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<p class=\"wp-block-paragraph\">However, it is risky to find the right product by applying various moisturizers directly to the affected areas, as an incompatible moisturizer can worsen dermatitis. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A more systematic way to reduce trial and error is to test multiple moisturizers simultaneously on a non-affected area and then apply only the samples of the products that passed that test to the actual lesions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To see how we assist with this process, please check the <a href=\"https:\/\/miragen.clinic\/en\/md-cream\/\" data-type=\"page\" data-id=\"6428\">MD Cream Guide<\/a>.<\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img decoding=\"async\" src=\"https:\/\/miragen.clinic\/wp-content\/uploads\/2026\/06\/moisturizer-patch-test-screening-EN.png\" alt=\"Patch test photo showing 10 atopic moisturizer creams including Atobarrier, Zeroid, and CellFusionC applied to the inner arm, demonstrating the patch testing process for selecting individually suitable moisturizers\" class=\"wp-image-4537\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"765\" src=\"https:\/\/miragen.clinic\/wp-content\/uploads\/2026\/03\/zeroid-md-sample-sachets.jpg\" alt=\"Zeroid MD Intensive Cream, Lotion, and Rootheal Sample Pouches - Medical Moisturizers at MIRAGEN Clinic\" class=\"wp-image-6368\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">References<\/h3>\n\n\n\n<ol class=\"wp-block-list has-custom-color-5-color has-text-color has-link-color has-superbfont-xxsmall-font-size wp-elements-5d14346eb8f4e5f2ba14b3ba53873ff6\">\n<li><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/28432721\/\" target=\"_blank\" rel=\"noopener\"><em>van Zuuren EJ, Fedorowicz Z, Arents BWM.

Ingredients like emulsifiers or preservatives, which should stay on the surface when the barrier is healthy, can enter through gaps in the stratum corneum and trigger irritation or allergic reactions. This is often a matter of the skin barrier&#8217;s condition rather than a problem with Zeroid MD itself.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-2\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Which should I choose among Zeroid MD Rich Cream, Cream, and Lotion?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The decision is made after checking sebum levels through a Wood&#8217;s lamp examination and clinical findings. If sebum secretion is low and dryness is severe, Intensive Rich Cream MD (the strongest moisturizer) is suitable. Intensive Cream MD is used for general facial moisturizing, and Intensive Lotion MD is appropriate for the body or areas with high sebum secretion. For the scalp, Rootheal Moisturizer MD is used because oily formulations can irritate Malassezia.  <\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-3\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">How does Zeroid MD compare to other MD creams?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>There are various MD cream brands such as Aestura, Cell Fusion C, and Intrinsic, each with multiple products. It is difficult to say which one is the best because the right product varies for each individual. Even within the same brand, some products may work well while others do not. Comparing multiple MD creams simultaneously through patch testing allows you to efficiently filter out products that do not suit your skin.    <\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-group has-custom-color-2-background-color has-background has-global-padding is-layout-constrained wp-container-core-group-is-layout-ffa602f6 wp-block-group-is-layout-constrained\" style=\"border-top-left-radius:16px;border-top-right-radius:16px;border-bottom-left-radius:16px;border-bottom-right-radius:16px;padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8c970b27 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:40%\">\n<figure class=\"wp-block-image size-full\" style=\"margin-right:0;margin-left:0\"><img decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/miragen.clinic\/wp-content\/uploads\/2026\/01\/doctor-han-namecard-profile.png\" alt=\"\" class=\"wp-image-3537\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"padding-top:var(--wp--preset--spacing--superbspacing-small);padding-right:var(--wp--preset--spacing--superbspacing-small);padding-bottom:var(--wp--preset--spacing--superbspacing-small);padding-left:var(--wp--preset--spacing--superbspacing-small);flex-basis:60%\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-dec8e639 wp-block-group-is-layout-constrained\" style=\"padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">\n<p class=\"has-custom-color-3-color has-text-color has-link-color has-superbfont-large-font-size wp-elements-9a43ded5a855c918bdce811724da93c4 wp-block-paragraph\" style=\"font-style:normal;font-weight:600\">We treat atopic dermatitis, rosacea, and seborrheic dermatitis.<br\/><\/p>\n\n\n\n<p class=\"has-custom-color-5-color has-text-color has-link-color has-superbfont-small-font-size wp-elements-b0ed9896cd87c4dc29ef35753e45458c wp-block-paragraph\">Thanks to the valuable reviews you have shared in the community, many of you visit us even from far away.<br\/>We will repay you with sincere, attentive care.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-custom-color-6-color has-alpha-channel-opacity has-custom-color-6-background-color has-background is-style-wide\"\/>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-e1e686a6 wp-block-columns-is-layout-flex\" style=\"padding-top:0;padding-bottom:0\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-19afc361 wp-block-group-is-layout-flex\">\n<p class=\"has-custom-color-3-color has-text-color has-link-color has-superbfont-small-font-size wp-elements-5046f5cbf2504632740a9221c469d447 wp-block-paragraph\"><strong>DK Han<\/strong><\/p>\n\n\n\n<p class=\"has-custom-color-5-color has-text-color has-link-color has-superbfont-xsmall-font-size wp-elements-f628b1a898e0079d43059baed3da5249 wp-block-paragraph\">Chief Director, MIRAGEN Clinic<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<p class=\"has-custom-color-5-color has-text-color has-link-color has-superbfont-xsmall-font-size wp-elements-0a159b55280bf6519f7c0f2e7a7ab305 wp-block-paragraph\">Graduate of University of Michigan, Ross School of Business<br\/>Graduate of Chungnam National University School of Medicine<br\/>(Former) Representative Director of Ewha Phoenix Rehabilitation Hospital<br\/>(Current) Representative Director of MIRAGEN Clinic<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>When we ask dermatitis patients which moisturizer they use, Zeroid MD is one of the most common names mentioned.
