Even though these products were cheap, nail techs often had to extend treatment times or redo services, decreasing work efficiency and increasing the amount of rework to be done.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p>To solve this problem, the chain found a more reliable gel manufacturer and went for product trials with <mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-pale-pink-color\"><strong><a href=\"https:\/\/www.fsyougel.com\/fr\/\">Yougel<\/a><\/strong><\/mark>, resulting in an optimized Top Coat formula built around the specific needs of the salon. Quick curing is possible under normal UV\/LED lamps (48W), while ensuring a constant gloss.<\/p>\n\n\n\n<p>Once the new<strong> Top Coat <\/strong>had been put in place, the salon witnessed big improvements like reduced cure times, smoother nail beds, gloss longevity, and higher staff productivity. For the salon chain, getting stable products guaranteed not only service quality enhancement, but also reduction in post-service issues caused by product defects.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Yougel_Products_vs_Ordinary_Brands\"><\/span>Yougel Products vs. Ordinary Brands<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>\u00c9l\u00e9ment de comparaison<\/th><th>Low-Cost Brands<\/th><th>Yougel<\/th><\/tr><\/thead><tbody><tr><td>Formula Stability<\/td><td>Unstable<\/td><td>Developed in professional laboratories<\/td><\/tr><tr><td>Ingredient Safety<\/td><td>Not transparent<\/td><td>HEMA-Free \/ TPO-Free<\/td><\/tr><tr><td>Curing Performance<\/td><td>Prone to not drying<\/td><td>Fast curing<\/td><\/tr><tr><td>Product Variety<\/td><td>Limited<\/td><td>10,000+ colors<\/td><\/tr><tr><td>OEM Support<\/td><td>Rare<\/td><td>Full OEM\/ODM services<\/td><\/tr><tr><td>MOQ<\/td><td>High<\/td><td>Starting from 300 bottles<\/td><\/tr><tr><td>Certifications<\/td><td>Few<\/td><td>GMPC \/ ISO \/ CPSR, etc.<\/td><\/tr><tr><td>Production Capacity<\/td><td>Unstable<\/td><td>Up to 50,000 bottles per day<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Yougel offers a complete product system with full customization for packaging, formula, and color:<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<ul class=\"wp-block-list\">\n<li>Couche de base<\/li>\n\n\n\n<li>Top Coat<\/li>\n\n\n\n<li>Gel de couleur<\/li>\n\n\n\n<li>Gel de construction<\/li>\n\n\n\n<li>Gel acrylique<\/li>\n<\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\"><div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.fsyougel.com\/fr\/custom-gel-polish\/\"><img decoding=\"async\" width=\"2283\" height=\"1133\" src=\"https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer.webp\" alt=\"Solutions personnalis\u00e9es d&#039;un fabricant professionnel de vernis en gel\" class=\"wp-image-243\" srcset=\"https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer.webp 2283w, https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer-300x149.webp 300w, https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer-768x381.webp 768w, https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer-1200x596.webp 1200w, https:\/\/www.fsyougel.com\/wp-content\/uploads\/2025\/08\/Custom-Solutions-from-a-Professional-Gel-Polish-Manufacturer-600x298.webp 600w\" sizes=\"(max-width: 2283px) 100vw, 2283px\" \/><\/a><\/figure>\n<\/div><\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Top_Coat_Quality_Matters_for_Buyers%EF%BC%9F\"><\/span>Why Top Coat Quality Matters for Buyers\uff1f<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In a gel nail product system, the Top Coat, though applied last, directly affects the final result and client experience. Therefore, Top Coat quality has become a key consideration when selecting suppliers:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Affects_final_gloss\"><\/span>Affects final gloss<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The Top Coat determines the nail\u2019s surface shine and overall appearance.

Use a 48W+ UV\/LED lamp, apply thin layers, and choose a high-quality Top Coat.<\/p>\n\n\n\n<p><strong>Q2: Is a sticky Top Coat surface a sign that it\u2019s uncured?<br>A2 :<\/strong> Not necessarily. Some Top Coats require wiping. Use cleanser or alcohol to achieve a smooth finish.<\/p>\n\n\n\n<p><strong>Q3: Why do some Top Coats yellow?<br>A3 : <\/strong>Often due to low-quality resin or poor light stability. Choosing a stable formula prevents yellowing.<\/p>\n\n\n\n<p><strong>Q4: Can I apply a thicker Top Coat for strength?<br>A4 : <\/strong>Not recommended. Top Coat is for protection and gloss; too thick affects curing. Use Builder Gel for added strength.<\/p>\n\n\n\n<p><strong>Q5: How long does it take to customize a Top Coat for a brand?<br>A5 :<\/strong> Includes sampling, testing, and production. Professional manufacturers offer fast sampling and OEM services for quicker market entry.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><strong><a href=\"https:\/\/www.fsyougel.com\/fr\/categorie-produit\/top-coat-wholesale\/\">Top Coat<\/a><\/strong> issues are typically related to liquid ingredients and application technique.
