It indicates how well a sunscreen reduces UVA exposure, which is linked to long-term skin damage such as aging and pigmentation. <sup>[2]<\/sup>\n\nIt is based on the PPD (Persistent Pigment Darkening) test, which measures how effectively a product reduces UVA-induced skin darkening. PA levels range from PA+ to PA++++, with more \u201c+\u201d signs indicating stronger UVA protection.\n\nSPF and PA measure different UV ranges and are not interchangeable. UVA exposure is a key driver of premature aging and pigmentation. <sup>[1]<\/sup>\n<ul>\n \t<li>PA+ = low UVA protection<\/li>\n \t<li>PA++ = moderate UVA protection<\/li>\n \t<li>PA+++ = high UVA protection<\/li>\n \t<li>PA++++ = very high UVA protection<\/li>\n \t<li>Higher PA = stronger UVA defense, not higher SPF<\/li>\n<\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-47ad339a elementor-widget elementor-widget-text-editor\" data-id=\"47ad339a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<figure id=\"attachment_3890\" aria-describedby=\"caption-attachment-3890\" style=\"width: 500px\" class=\"wp-caption alignnone\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-3890\" title=\"Detailed vertical sunscreen PA rating infographic explaining UVA protection levels (PA+, PA++, PA+++, PA++++)\" src=\"https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA.webp\" alt=\"Detailed vertical sunscreen PA rating infographic explaining UVA protection levels (PA+, PA++, PA+++, PA++++)\" width=\"500\" height=\"888\" srcset=\"https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA.webp 941w, https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA-169x300.webp 169w, https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA-576x1024.webp 576w, https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA-768x1365.webp 768w, https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA-864x1536.webp 864w, https:\/\/www.zicailbeauty.com\/wp-content\/uploads\/2026\/06\/Detailed-vertical-sunscreen-PA-rating-infographic-explaining-UVA-protection-levels-PA-PA-PA-PA-7x12.webp 7w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><figcaption id=\"caption-attachment-3890\" class=\"wp-caption-text\">Detailed vertical sunscreen PA rating infographic<\/figcaption><\/figure>\n<h2>How PA Rating Works (UVA Protection System)<\/h2>\nPA rating is based on UVA skin response rather than sunburn. UVA penetrates deeper than UVB and is linked to collagen breakdown, pigmentation, and long-term aging. <sup>[2]<\/sup>\n\nIt is linked to <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21250967\/\">the PPD (Persistent Pigment Darkening) method<\/a>, which measures the level of UVA exposure required to trigger visible skin darkening. Higher PPD values correspond to stronger UVA protection and higher PA grades. <sup>[3]<\/sup>\n\nThe system was created to address SPF limitations, which only measure UVB. Because UVA is present daily\u2014even through clouds and glass\u2014PA labeling is widely used in Asia, while other regions often use \u201c<a href=\"https:\/\/www.zicailbeauty.com\/what-is-broad-spectrum-sunscreen\/\">Broad Spectrum<\/a>\u201d labeling instead. <sup>[1]<\/sup><sup>[4]<\/sup>\n<ul>\n \t<li>UVA penetrates deeper than UVB<\/li>\n \t<li>UVA is linked to pigmentation and photoaging<\/li>\n \t<li>PA system measures UVA protection strength<\/li>\n \t<li>Higher PA = higher PPD value<\/li>\n \t<li>Not all countries use PA labeling<\/li>\n<\/ul>\n<h2>PA Rating vs SPF: What\u2019s the Difference?<\/h2>\nSPF and PA measure different parts of UV protection. <a href=\"https:\/\/www.zicailbeauty.com\/what-spf-means-in-sunscreen\/\">SPF reflects UVB protection<\/a>, while PA reflects UVA protection, which is linked to long-term skin changes such as aging and pigmentation. <sup>[1]<\/sup>\n\nThey are complementary rather than interchangeable. A high SPF does not guarantee strong UVA protection, and a high PA rating does not indicate UVB protection strength.\n\nFull photoprotection requires both UVA and UVB coverage, which is why broad-spectrum sunscreens combine SPF with UVA protection systems such as PA or equivalent regional standards. <sup>[4]<\/sup>\n<div style=\"overflow-x: auto; max-width: 100%; max-height: 500px;\">\n<table>\n<thead>\n<tr>\n<th>Feature<\/th>\n<th>SPF<\/th>\n<th>PA Rating<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Protection type<\/td>\n<td>UVB protection<\/td>\n<td>UVA protection<\/td>\n<\/tr>\n<tr>\n<td>UV range<\/td>\n<td>Short-wave UV radiation<\/td>\n<td>Long-wave UV radiation<\/td>\n<\/tr>\n<tr>\n<td>Main concern<\/td>\n<td>Sunburn and immediate damage<\/td>\n<td>Aging, pigmentation, long-term damage<\/td>\n<\/tr>\n<tr>\n<td>Measurement system<\/td>\n<td>SPF index based on UVB erythema response<\/td>\n<td>PPD-based UVA protection grading<\/td>\n<\/tr>\n<tr>\n<td>Daily relevance<\/td>\n<td>Prevents burning during exposure<\/td>\n<td>Prevents cumulative skin aging<\/td>\n<\/tr>\n<tr>\n<td>Limitations<\/td>\n<td>Does not fully reflect UVA protection<\/td>\n<td>Does not measure UVB protection or burning risk<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<strong>Key takeaway:<\/strong> SPF alone does not provide full-spectrum protection. PA completes the UVA side of sun defense, and only the combination of both provides a more complete photoprotection profile.\n<h2>PA Levels Explained (PA+, PA++, PA+++, PA++++)<\/h2>\nPA levels represent increasing UVA protection strength, with more \u201c+\u201d signs indicating higher protection against UVA-induced skin stress and pigmentation.\n\nEach level corresponds to real-world exposure intensity rather than different protection categories. Lower levels work for limited exposure, while higher levels are designed for stronger or prolonged sunlight conditions.\n<ul>\n \t<li>PA+ \u2192 Basic protection for short exposure or mostly indoor routines<\/li>\n \t<li>PA++ \u2192 Moderate protection for typical daily outdoor activity<\/li>\n \t<li>PA+++ \u2192 High protection for extended outdoor time or strong sunlight<\/li>\n \t<li>PA++++ \u2192 Very high protection for intense UV environments such as travel, beach, or high-altitude exposure<\/li>\n<\/ul>\nHigher PA is not always necessary. The appropriate level depends on exposure duration and UV intensity.\n<h2>Do You Need High PA Sunscreen?<\/h2>\nHigh PA sunscreen is not necessary for everyone. The right level depends on UV exposure, skin sensitivity, and long-term aging concerns. Moderate PA is often sufficient for low exposure, while higher levels are better suited for stronger or prolonged sunlight.\n\nThe goal is to match PA level with real exposure rather than choosing the highest rating by default.\n<ul>\n \t<li><strong>Oily \/ acne-prone skin:<\/strong> lightweight high PA formulas for daily comfort<\/li>\n \t<li><strong>Pigmentation-prone skin:<\/strong> higher PA to reduce dark spot formation<\/li>\n \t<li><strong>Indoor lifestyle:<\/strong> PA++\u2013PA+++ is usually sufficient<\/li>\n \t<li><strong>Outdoor \/ tropical regions:<\/strong> PA+++\u2013PA++++ for stronger UV conditions<\/li>\n \t<li><strong>Anti-aging concern:<\/strong> higher UVA protection for long-term skin preservation<\/li>\n<\/ul>\n<h2>How to Choose Sunscreen Based on PA Rating<\/h2>\n<a href=\"https:\/\/www.zicailbeauty.com\/how-to-choose-the-right-sunscreen\/\">Choosing sunscreen<\/a> based on PA rating should follow exposure patterns rather than assuming higher is always better. The correct PA level depends on outdoor time, UV intensity, and sensitivity to pigmentation or aging. <sup>[1]<\/sup>\n<div style=\"overflow-x: auto; max-width: 100%; max-height: 500px;\">\n<table>\n<thead>\n<tr>\n<th>User Type<\/th>\n<th>Recommended PA Level<\/th>\n<th>Reason<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Office workers<\/td>\n<td>PA++\u2013PA+++<\/td>\n<td>Moderate UVA exposure through windows and short outdoor periods<\/td>\n<\/tr>\n<tr>\n<td>Outdoor workers<\/td>\n<td>PA+++\u2013PA++++<\/td>\n<td>Continuous sunlight exposure requiring stronger UVA defense<\/td>\n<\/tr>\n<tr>\n<td>Sensitive \/ pigmentation-prone skin<\/td>\n<td>PA+++\u2013PA++++<\/td>\n<td>Reduced risk of UVA-triggered dark spots and uneven tone<\/td>\n<\/tr>\n<tr>\n<td>Travelers \/ beach users<\/td>\n<td>PA++++<\/td>\n<td>High-intensity UV environments with prolonged exposure<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\nConsistency matters more than switching products frequently. Choose a PA level that matches your daily exposure pattern and use it regularly.\n<h2>Limitations of PA Rating<\/h2>\nPA rating is a useful indicator of UVA protection strength, but it does not represent full real-world sunscreen performance under all conditions. <sup>[3]<\/sup> Controlled testing environments cannot fully reflect <a href=\"https:\/\/www.zicailbeauty.com\/how-does-sunscreen-work\/\">how sunscreen behaves<\/a> under heat, sweat, friction, or uneven application. In practice, application amount and reapplication frequency have a greater impact on actual protection than the PA value itself.\n\nAnother limitation is the lack of global standardization. Different regions use different UVA labeling systems, such as PA or Broad Spectrum, which reduces cross-market consistency. <sup>[4]<\/sup> In addition, PA does not evaluate full UVA wavelength coverage, as performance depends on the specific UV filter system used in formulation.\n\nKey limitations include differences between laboratory testing and real-world use, lack of global labeling consistency, and incomplete representation of UVA filter performance.\n<ul>\n \t<li>Based on controlled laboratory testing, not real-world usage conditions<\/li>\n \t<li>Does not account for texture, feel, or application behavior on skin<\/li>\n \t<li>Cannot replace broad-spectrum UVA\/UVB labeling systems<\/li>\n \t<li>Does not guarantee water resistance or durability in wet conditions<\/li>\n<\/ul>\n<h2>Final Takeaway: What PA Rating Really Means<\/h2>\nPA rating is a practical indicator of UVA protection strength, while SPF represents UVB protection. <sup>[1]<\/sup> Together, they describe two different but equally important parts of sun protection. Neither system alone is sufficient for full photoprotection.\n\nHigher PA levels provide stronger defense against UVA-related skin changes, but real effectiveness still depends on correct application, adequate amount, and regular reapplication during exposure. For complete protection, both SPF and PA need to be considered as a combined system rather than separate labels.\n<h2>FAQs About PA Sunscreen Rating<\/h2>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-030a291 elementor-widget elementor-widget-n-accordion\" data-id=\"030a291\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;max_items_expended&quot;:&quot;multiple&quot;,&quot;default_state&quot;:&quot;expanded&quot;,&quot;n_accordion_animation_duration&quot;:{&quot;unit&quot;:&quot;ms&quot;,&quot;size&quot;:400,&quot;sizes&quot;:[]}}\" data-widget_type=\"nested-accordion.default\">\n\t\t\t\t\t\t\t<div class=\"e-n-accordion\" aria-label=\"Accordion.
