Melanin is the natural pigment your body produces that gives your skin its distinct color. Using hydroquinone with other sun protection, such as sunscreen, can help dark spots fade away with time.<\/p>\n\n\n\n<div class=\"quick-facts-card\">\n  <table class=\"quick-facts-table\">\n    <colgroup>\n      <col\/>\n      <col\/>\n    <\/colgroup>\n\n    <thead>\n      <tr>\n        <th colspan=\"2\">Quick Facts<\/strong><\/td>\n      <\/tr>\n    <\/thead>\n\n    <tbody>\n    <tr>\n    <td><strong>Common Brands<\/strong><\/td>\n    <td>Obagi-C, Melquin HP<\/td> \n  <\/tr>\n  <tr>\n    <td><strong>Drug Class<\/strong><\/td>\n    <td>Skin-lightening agent<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Generic Status<\/strong><\/td>\n    <td>Generic version of Obagi-C, Melquin HP<\/td>\n  <\/tr>\n  <tr>\n    <td><strong>Availability<\/strong><\/td>\n    <td>Prescription only<\/td>\n  <\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"dosing\">Dosing<\/h2>\n\n\n\n<p>Hydroquinone is typically applied to the affected areas of the skin twice daily, or exactly as directed by your healthcare provider.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Wash and dry the skin first.<\/strong> It\u2019s recommended to wash and dry your hands thoroughly before and after applying the medication.

Common side effects are typically localized to the area where the cream is applied. These effects may improve over time as your body adjusts to the medication. Other side effects may be serious and require medical attention.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Common Side Effects<\/h3>\n\n\n\n<div class=\"telyrx-side-effects-chip telyrx-side-effects-chip--common\">\n\t\n\n<ul class=\"wp-block-list\">\n<li>Skin dryness<\/li>\n\n\n\n<li>Skin redness<\/li>\n\n\n\n<li>Stinging or burning sensation<\/li>\n\n\n\n<li>Mild skin irritation<\/li>\n\n\n\n<li>Cracking or peeling skin<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Serious Side Effects<\/h3>\n\n\n\n<div class=\"telyrx-side-effects-chip telyrx-side-effects-chip--serious\">\n\t\n\n<p>Serious side effects are rare, but it&#8217;s important to know what to look for if they do occur. Stop using hydroquinone and call your doctor immediately if you experience:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Severe allergic reactions:<\/strong> Symptoms include swelling of the face, lips, tongue, or throat; difficulty breathing or swallowing; severe rash or itching; and\/or fever.<\/li>\n\n\n\n<li><strong>Darkening of the skin (exogenous ochronosis):<\/strong> This is a rare condition characterized by a gradual blue-black darkening of the skin. This risk is higher in Black people, but it can occur in Hispanic and Caucasian people as well.<\/li>\n\n\n\n<li><strong>Severe skin irritation (contact dermatitis): <\/strong>&nbsp;While hydroquinone can cause mild contact dermatitis, severe reactions can also occur, such as severe blistering, crusting, burning, or swelling of the treated skin.<\/li>\n<\/ul>\n\n<\/div>\n\n\n\n<p class=\"has-muted-color has-text-color\" style=\"font-size:0.875rem\"><em>Call your doctor immediately if you experience any concerning or prolonged symptoms.<\/em><\/p>\n\n\t<\/div>\n<\/section>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"pharmacist-tips\">Pharmacist Tips<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"perform-a-patch-test\">Perform a Patch Test<\/h3>\n\n\n\n<p>Before using hydroquinone for the first time, it is recommended to apply a small amount to an unbroken spot of skin. Wait 24 hours to check for severe reactions such as blistering or extreme itching. If only minor redness or itching occurs, it is generally considered safe to proceed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"use-sun-protection\">Use Sun Protection<\/h3>\n\n\n\n<p>When using hydroquinone, it is recommended to use sunscreen with an SPF of 30 or higher, wear protective clothing to cover the treated skin, and avoid sunlamps and tanning beds. Even a small amount of sunlight can darken the treated area again, reversing the effects of the medication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"store-it-at-room-temperature\">Store It At Room Temperature<\/h3>\n\n\n\n<p>Hydroquinone should be stored at room temperature between 68\u00b0F and 77\u00b0F (20\u00b0C and 25\u00b0C), although it can be temporarily exposed to lower temperatures if needed (such as transportation). Keep it in a cool, dry place and ensure the container is tightly closed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"monitor-your-progress\">Monitor Your Progress<\/h3>\n\n\n\n<p>If you do not see any improvement after two months of treatment with the cream (or three months with the solution), consult your healthcare provider.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"drug-interactions\">Drug Interactions<\/h2>\n\n\n\n<p>Hydroquinone can interact with other medications, potentially altering their effectiveness or increasing the risk of side effects. For example:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Benzoyl peroxide:<\/strong> This topical acne treatment may interact with hydroquinone and should not be used at the same time.<\/li>\n\n\n\n<li><strong>Photosensitizing medications:<\/strong> If you are taking other medications that increase sensitivity to sunlight \u2014 such as doxycycline, methotrexate, or tretinoin (Retin-A) \u2014 extra care is required to protect your skin from UV exposure.<\/li>\n\n\n\n<li><strong>Other topicals:<\/strong> Before starting hydroquinone, ask your healthcare provider if it is safe to combine it with your current prescription or over-the-counter creams, lotions, or supplements.<\/li>\n<\/ul>\n\n\n\n<p>Always give your doctor and pharmacist a complete list of all your medications, vitamins, and supplements to check for potential interactions.<\/p>\n\n\n\n<section class=\"telyrx-faq-section\" data-toc-title=\"FAQs\">\n\t<h2 class=\"telyrx-faq-heading\">FAQs<\/h2>\n\t\t<div class=\"telyrx-faq-items\">\n\t\t\n\n<details class=\"telyrx-faq-item\">\n\t<summary class=\"telyrx-faq-question\">\n\t\t<span class=\"telyrx-faq-question-text\">How long does it take to see results from hydroquinone?<\/span>\n\t\t<svg class=\"telyrx-faq-chevron\" width=\"20\" height=\"20\" viewBox=\"0 0 20 20\" fill=\"none\" aria-hidden=\"true\">\n\t\t\t<path d=\"M5 7.5L10 12.5L15 7.5\" stroke=\"currentColor\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\/>\n\t\t<\/svg>\n\t<\/summary>\n\t<div class=\"telyrx-faq-answer\">\n\t\t\n\n<p>While individual results vary, people typically apply the cream twice daily.
