Find out by learning about the benefits of polyhydroxy acid, how it differs from other chemical exfoliants, and how to find the best PHA products for you.<\/em>\r\n\r\nExfoliants are among the best skincare products to have in your routine. After all, the <a href=\"https:\/\/www.humnutrition.com\/blog\/physical-vs-chemical-exfoliation\/\" target=\"_blank\" rel=\"noopener\">benefits of exfoliating<\/a> include but aren&#8217;t limited to:\r\n<ul>\r\n \t<li>combatting dullness<\/li>\r\n \t<li>clearing breakouts<\/li>\r\n \t<li>aiding <a href=\"https:\/\/www.humnutrition.com\/blog\/skin-cell-turnover\/\">skin cell turnover<\/a><\/li>\r\n<\/ul>\r\nHowever, when it comes to chemical exfoliants, different types work their magic in different ways. Further, some are more sensitizing than others. If you find that your skin doesn&#8217;t traditionally take well to exfoliating, there&#8217;s a trending acid worth investigating: PHAs.\r\n\r\nTo learn more about PHA skincare, we spoke to\u00a0<a href=\"https:\/\/www.instagram.com\/xo.healthy\/\" target=\"_blank\" rel=\"noopener\">Xochitl Renteln, PA-C<\/a>, a skincare specialist at <a href=\"https:\/\/www.facileskin.com\/\" target=\"_blank\" rel=\"noopener\">facile dermatology + boutique<\/a>\u00a0in Los Angeles.\r\n<h2>What is PHA Skincare?<\/h2>\r\nPolyhydroxy acid (PHA) is a gentle chemical exfoliant. Different types of PHAs include gluconolactone and lactobionic acid.\r\n\r\nAs Xochitl explains, &#8220;These acids exfoliate the top layer of dead skin cells by breaking the bonds between them, allowing them to shed more easily.&#8221;\r\n\r\nThis process yields such as benefits as:\r\n<ul>\r\n \t<li>lighter dark spots<\/li>\r\n \t<li>a brighter complexion<\/li>\r\n \t<li>smoother skin texture<\/li>\r\n<\/ul>\r\nBut that&#8217;s not all: Polyhydroxy acids have additional properties that target other skin concerns. &#8220;They also act as humectants and can help retain moisture in the skin,&#8221; Xochitl adds.\r\n\r\n&#8220;Finally, they can strengthen skin by combating glycation processes (which <a href=\"https:\/\/www.humnutrition.com\/blog\/collagen-fix\/\" target=\"_blank\" rel=\"noopener\">weakens collagen<\/a>) and through their antioxidant properties,&#8221; she continues. More collagen and antioxidant protection mean fewer signs of premature aging, such as fine lines, wrinkles, and UV damage.\r\n\r\n<img data-dominant-color=\"a58763\" data-has-transparency=\"false\" style=\"--dominant-color: #a58763;\" decoding=\"async\" class=\"size-full wp-image-25335 aligncenter not-transparent\" src=\"https:\/\/www.humnutrition.com\/blog\/wp-content\/uploads\/2021\/07\/What-is-PHA-Polyhydroxy-Acid-The-Wellnest-by-HUM-Nutrition.jpg\" alt=\"Man washing his face with PHA chemical exfoliants in outdoor shower\" width=\"770\" height=\"513\" \/>\r\n<h2>How do they differ from AHA and BHA exfoliants?<\/h2>\r\nAlpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs) are well-known in the world of chemical exfoliation.\r\n\r\nSo how do PHAs stack up in comparison?\r\n<h3>PHA vs. AHA<\/h3>\r\n&#8220;PHAs are most chemically and functionally similar to AHAs, such as glycolic acid,&#8221; Xochitl explains. (Other types of AHAs include but aren&#8217;t limited to <a href=\"https:\/\/www.humnutrition.com\/blog\/lactic-acid-best-exfoliator-for-sensitive-skin\/\" target=\"_blank\" rel=\"noopener\">lactic acid<\/a>, malic acid, and mandelic acid.)\r\n\r\nHowever, since the molecule size of PHAs is much larger, they&#8217;re &#8220;more gentle exfoliants since they&#8217;re unable to penetrate the skin as deeply.&#8221; Because PHAs are best at penetrating the stratum corneum (the skin&#8217;s most superficial layer), they&#8217;re less likely to cause irritation, sensitivity, and compromised <a href=\"https:\/\/www.humnutrition.com\/blog\/skin-barrier\/\" target=\"_blank\" rel=\"noopener\">skin barrier function<\/a>.\r\n\r\nShe shares that AHAs are ideal for normal to dry skin that can tolerate a deeper clean.\r\n<h3>PHA vs. BHA<\/h3>\r\nSince BHAs are oil-soluble, they&#8217;re famed for their power to penetrate pores to help clear breakouts. (Salicylic acid is the most common form of BHA. Additionally, <a href=\"https:\/\/www.humnutrition.com\/blog\/plant-based-skincare-swaps\/\" target=\"_blank\" rel=\"noopener\">plant-based willow bark extract<\/a> contains salicin, which itself metabolizes into salicylic acid.)\r\n\r\nConversely, as we learned above, PHAs provide more of a surface-level polish.\r\n\r\nSince BHAs work deep inside the pores to remove excess sebum, Xochitl says that they&#8217;re also ideal for oily skin. That said, normal skin types may also enjoy the benefits of exfoliating with BHAs.\r\n\r\n<img data-dominant-color=\"bcad9c\" data-has-transparency=\"false\" style=\"--dominant-color: #bcad9c;\" decoding=\"async\" class=\"size-full wp-image-25336 aligncenter not-transparent\" src=\"https:\/\/www.humnutrition.com\/blog\/wp-content\/uploads\/2021\/07\/Pha-exfoliant-Benefits-The-Wellnest-by-HUM-Nutrition.jpg\" alt=\"Black woman combating hyperpigmentation thats to PHA exfoliants\" width=\"770\" height=\"514\" \/>\r\n<h2>What skin types and concerns are best suited for PHA products?<\/h2>\r\nBecause of their large molecular structure, polyhydroxy acids are generally safe for most skin types. However, they&#8217;re particularly beneficial for people with the following skin types and concerns.\r\n<h3>Sensitive Skin<\/h3>\r\nAgain, since PHAs are gentle, they&#8217;re a great chemical exfoliant for sensitive skin that&#8217;s <a href=\"https:\/\/www.humnutrition.com\/blog\/can-you-exfoliate-too-much\/\" target=\"_blank\" rel=\"noopener\">prone to reactivity<\/a>.\r\n<h3>Dry + Dehydrated Skin<\/h3>\r\n&#8220;Since PHAs are humectants, they may also be more hydrating than traditional chemical exfoliants,&#8221; Xochitl reiterates. &#8220;Therefore, they&#8217;re a good alternative for those with drier skin&#8221; and <a href=\"https:\/\/www.humnutrition.com\/blog\/dehydrated-skin\/\" target=\"_blank\" rel=\"noopener\">bouts of dehydration<\/a>.\r\n<h3>Darker Skin Tones<\/h3>\r\nLastly, <a href=\"https:\/\/www.humnutrition.com\/blog\/how-to-treat-hyperpigmentation\/\" target=\"_blank\" rel=\"noopener\">hyperpigmentation is a common concern<\/a>\u00a0particularly for those with darker skin tones. Fortunately, Xochitl says that PHA skincare is safe and effective for people with melanin-rich skin that may otherwise react to treatments by developing dark spots.\r\n<h2>How to Add PHA Exfoliants to Your Skincare Routine<\/h2>\r\nReady to dive into the wonderful world of PHA skincare? Here are some quick tips to get started.\r\n<h3>1. Choose Your Formulation<\/h3>\r\nPHA products take on a range of forms, including:\r\n<ul>\r\n \t<li>cleansers<\/li>\r\n \t<li><a href=\"https:\/\/www.humnutrition.com\/blog\/toner\/\" target=\"_blank\" rel=\"noopener\">toners<\/a><\/li>\r\n \t<li><a href=\"https:\/\/www.humnutrition.com\/blog\/what-serum-should-i-use\/\" target=\"_blank\" rel=\"noopener\">serums<\/a><\/li>\r\n \t<li>moisturizers<\/li>\r\n \t<li>facial mists<\/li>\r\n \t<li>masks<\/li>\r\n<\/ul>\r\nUltimately, it&#8217;s up to you to choose which one is right for you (or, if you <a href=\"https:\/\/www.humnutrition.com\/blog\/sustainable-skincare-tips\/\" target=\"_blank\" rel=\"noopener\">err towards sustainability<\/a>, which skincare product type you run out of first). However, Xochitl suggests opting for something that sits longer on the skin since &#8220;it takes some time for the bonds between the superficial skin cells to be broken.&#8221;\r\n<h4>Best PHA Products<\/h4>\r\nI recommend <a href=\"https:\/\/sokoglam.com\/products\/some-by-mi-aha-bha-pha-30days-miracle-toner\" target=\"_blank\" rel=\"noopener\">this PHA toner from Some by Mi<\/a>. It also includes AHAs, BHAs, and <a href=\"https:\/\/www.humnutrition.com\/blog\/niacinamide-skin-benefits\/\" target=\"_blank\" rel=\"noopener\">niacinamide<\/a>, which my combination\/hyperpigmentation-prone skin loves.\r\n\r\nLooking for a gentler PHA toner without additional acids? <a href=\"https:\/\/www.sephora.com\/product\/poly-hydroxide-acid-toner-P450262\" target=\"_blank\" rel=\"noopener\">This budget-conscious option from The Inkey List<\/a> packs skin-friendly niacinamide and soothing aloe.\r\n\r\nOtherwise, if you&#8217;re more concerned about premature signs of aging, you may want to consider using <a href=\"https:\/\/www.sephora.com\/product\/herbivore-botanicals-bakuchiol-retinol-alternative-smoothing-serum-P465761\" target=\"_blank\" rel=\"noopener noreferrer\">Herbivore&#8217;s Bakuchiol Retinol Alternative Smoothing Serum<\/a>.\r\n\r\n<img data-dominant-color=\"c78865\" data-has-transparency=\"false\" style=\"--dominant-color: #c78865;\" decoding=\"async\" class=\"size-full wp-image-25339 aligncenter not-transparent\" src=\"https:\/\/www.humnutrition.com\/blog\/wp-content\/uploads\/2021\/07\/Best-PHA-Products-The-Wellnest-by-HUM-Nutrition.jpg\" alt=\"Woman applying PHA serum from a dropper\" width=\"770\" height=\"514\" \/>\r\n<h3>2. Be Cautious of Product Pairings<\/h3>\r\nAs we can see, PHAs tend to pair well with other skincare actives.\r\n\r\n&#8220;PHAs are versatile and gentle, making them easier to combine with other active ingredients compared to AHAs and BHAs,&#8221; Xochitl shares. However, while they&#8217;re most often available as a package deal, it&#8217;s important to remember that the ability to tolerate these combos varies from person to person.\r\n\r\nSimilarly, you should be cautious when it comes to pairing PHA skincare with other products in your routine. &#8220;I don&#8217;t recommend combining vitamin C with PHAs, AHAs, or BHAs,&#8221; Xochitl notes, as doing so runs a greater risk of sensitivity. She also flags retinoids for similar reasons.\r\n\r\nHowever, this isn&#8217;t to say that you should shun these ingredients completely. (Personally, my skin is pretty tolerant and takes well to vitamin C serum layered over my PHA toner.) After all, both <a href=\"https:\/\/www.humnutrition.com\/blog\/what-does-vitamin-c-do-for-your-skin\/\" target=\"_blank\" rel=\"noopener\">topical vitamin C<\/a> and retinoids can produce incredible benefits for your skin.\r\n\r\nInstead, you can mix up your regimen by:\r\n<ul>\r\n \t<li>using one active in the morning + another at night<\/li>\r\n \t<li>alternating the days on which you apply PHA products, vitamin C + <a href=\"https:\/\/www.humnutrition.com\/blog\/retinol-in-your-20s\/\" target=\"_blank\" rel=\"noopener\">retinoids\/retinol<\/a><\/li>\r\n<\/ul>\r\n<h3>3. Start Slowly<\/h3>\r\nOn a final note, you should take a slow and steady approach any time you incorporate a new active ingredient into your skincare routine\u2014and PHA exfoliants are no exception.\r\n\r\n&#8220;Despite their gentleness, PHA is still an acid,&#8221; Xochitl reminds us. &#8220;I would start low (maybe twice weekly), increase slowly, and proceed&#8221; after figuring out the best PHA groove for you.\n<div  class=\"products-block -mx-4 md:mx-0 my-10\">\n\t\t\t\t<a href=\"https:\/\/www.humnutrition.com\/product\/42\/hyaluronic-glow-gummies\" class=\"text-xs text-dark hover:!text-dark flex items-center border border-light rounded p-4 group !no-underline mb-4 relative pb-16 sm:pb-4\">\n\t\t\t\t<div class=\"shrink-0 mr-4\">\n\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/cdn.humnutrition.com\/assets\/16cebaf0-7edb-11f0-a056-b3bdb0090cfd.png\" width=\"100\" height=\"100\" class=\"object-cover transition-opacity group-hover:opacity-80 !mb-0\" alt=\"Hyaluronic Glow Gummies\">\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"grow pr-4\">\n\t\t\t\t\t<div class=\"mb-2 flex flex-col sm:flex-row sm:items-center divide-x-0 sm:divide-x divide-light text-sm\">\n\t\t\t\t\t\t<div class=\"pt-1 pr-2 flex\">\n\t\t\t\t\t\t\t<div class=\"flex mr-1\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg class=\"mr-1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"17\" height=\"16\"><path d=\"m11.532 4.697 4.353.663c.36.053.664.316.828.64.066.397 0 .791-.288 1.06l-3.157 3.193.745 4.581a1.01 1.01 0 0 1-.39.978c-.3.188-.698.25-1.022.072l-3.888-2.14-3.889 2.14c-.327.178-.724.116-1.024-.072a1.008 1.008 0 0 1-.388-.978l.745-4.581L1 7.06C.713 6.79.646 6.397.713 6c.162-.324.464-.587.827-.64l4.35-.663L7.842.563c.16-.344.5-.563.87-.563.372 0 .711.219.872.563z\"\/><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg class=\"mr-1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"17\" height=\"16\"><path d=\"m11.532 4.697 4.353.663c.36.053.664.316.828.64.066.397 0 .791-.288 1.06l-3.157 3.193.745 4.581a1.01 1.01 0 0 1-.39.978c-.3.188-.698.25-1.022.072l-3.888-2.14-3.889 2.14c-.327.178-.724.116-1.024-.072a1.008 1.008 0 0 1-.388-.978l.745-4.581L1 7.06C.713 6.79.646 6.397.713 6c.162-.324.464-.587.827-.64l4.35-.663L7.842.563c.16-.344.5-.563.87-.563.372 0 .711.219.872.563z\"\/><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg class=\"mr-1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"17\" height=\"16\"><path d=\"m11.532 4.697 4.353.663c.36.053.664.316.828.64.066.397 0 .791-.288 1.06l-3.157 3.193.745 4.581a1.01 1.01 0 0 1-.39.978c-.3.188-.698.25-1.022.072l-3.888-2.14-3.889 2.14c-.327.178-.724.116-1.024-.072a1.008 1.008 0 0 1-.388-.978l.745-4.581L1 7.06C.713 6.79.646 6.397.713 6c.162-.324.464-.587.827-.64l4.35-.663L7.842.563c.16-.344.5-.563.87-.563.372 0 .711.219.872.563z\"\/><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg class=\"mr-1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"17\" height=\"16\"><path d=\"m11.532 4.697 4.353.663c.36.053.664.316.828.64.066.397 0 .791-.288 1.06l-3.157 3.193.745 4.581a1.01 1.01 0 0 1-.39.978c-.3.188-.698.25-1.022.072l-3.888-2.14-3.889 2.14c-.327.178-.724.116-1.024-.072a1.008 1.008 0 0 1-.388-.978l.745-4.581L1 7.06C.713 6.79.646 6.397.713 6c.162-.324.464-.587.827-.64l4.35-.663L7.842.563c.16-.344.5-.563.87-.563.372 0 .711.219.872.563z\"\/><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<svg class=\"mr-1\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"17\" height=\"16\"><path d=\"m8.713 3 1.54 3.61 3.46.58L11.207 10l.588 4-3.082-1.878zm4.555 7.253 3.157-3.193c.288-.269.354-.663.288-1.06-.164-.324-.467-.587-.828-.64l-4.353-.663L9.584.562A.965.965 0 0 0 8.713 0a.965.965 0 0 0-.871.562L5.89 4.697l-4.35.663c-.363.053-.665.316-.827.64-.067.397 0 .791.287 1.06l3.157 3.193-.745 4.581a1.01 1.01 0 0 0 .388.978c.3.188.697.25 1.024.072l3.889-2.14 3.888 2.14c.324.178.721.116 1.021-.072a1.01 1.01 0 0 0 .391-.978z\"\/><\/svg>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t4.6\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"pt-1 sm:pl-2 text-medium\">\n\t\t\t\t\t\t\t200 Reviews\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"text-base font-semibold mb-1 group-hover:text-primary\">Hyaluronic Glow Gummies<\/div>\n\t\t\t\t\t<div class=\"mb-2\">\n\t\t\t\t\t\tsupports hydrated, naturally glowing skin (formerly Glow Sweet Glow)\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"absolute bottom-4 left-4 right-4 sm:bottom-0 sm:left-0 sm:right-0 sm:relative inline-flex justify-center bg-primary group-hover:bg-primary-light text-white rounded py-3 px-12 leading-none text-center\">\n\t\t\t\t\t\t<span class=\"pr-1.5 border-r border-primary-lightest\">$26<\/span><span class=\"pl-1.5\">SHOP NOW<\/span>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"self-start\">\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/a>\n\t\t<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Is the PHA skincare trend here to stay?
