Technically, the term \u00abParfum \/ Fragrance\u00bb does not appear in the INCI. However, the formula contains several essential oils and fragrance compounds such as limonene, linalool, and geraniol. For those with sensitive skin, the absence of the word \u00abfragrance\u00bb does not guarantee the absence of fragrance ingredients or sensitizing substances. The key is to read the INCI list, not just the front label of the bottle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">My verdict<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Kiehl\u2019s offers an ambitious anti-aging formula featuring Pro-Xylane, niacinamide, rhamnose, and adenosine. However, the presence of essential oils and fragrance allergens makes it less suitable for sensitive skin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Scan your serum<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To find out if your serum is right for your skin type &nbsp;<a href=\"https:\/\/beautydecoded.go.link\/hEMHE\" target=\"_blank\" rel=\"noopener\">Download the Beauty Decoded app (iOS and Android)<\/a>&nbsp;Scan your products, decipher their INCI listings, and compare what the packaging promises with what the formula actually contains.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The rating depends on your skin!<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"559\" height=\"1024\" src=\"https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-559x1024.webp\" alt=\"\" class=\"wp-image-75039\" srcset=\"https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-559x1024.webp 559w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-164x300.webp 164w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-768x1408.webp 768w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-838x1536.webp 838w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-scaled.webp 1117w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-7x12.webp 7w, https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/analyse-serum-kielhs-600x1100.webp 600w\" sizes=\"(max-width: 559px) 100vw, 559px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>What Kiehl\u2019s promises: three promises\u2014\u00abvisibly plumper\u00bb skin, penetration into the deep layers of the skin, and a formula that\u2019s \u00abfree of fragrance and colorants.\u00bb One of these claims gives me pause\u2026 \ud83d\udccc See also: Remedy Copper Peptide Serum: Dr. Shah\u2019s formula from Doctorly, explained\u2026<\/p>","protected":false},"author":120,"featured_media":75037,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-75026","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-actualites"],"acf":[],"taxonomy_info":{"category":[{"value":1,"label":"Actualites"}]},"featured_image_src_large":["https:\/\/www.beautydecoded.com\/wp-content\/uploads\/2026\/10\/seum-kielhs-1024x686.jpg",1024,686,true],"author_info":{"display_name":"Sylvain David","author_link":"https:\/\/www.beautydecoded.com\/en\/author\/beautydecoded\/"},"comment_info":3,"category_info":[{"term_id":1,"name":"Actualites","slug":"actualites","term_group":0,"term_taxonomy_id":1,"taxonomy":"category","description":"","parent":0,"count":349,"filter":"raw","cat_ID":1,"category_count":349,"category_description":"","cat_name":"Actualites","category_nicename":"actualites","category_parent":0}],"tag_info":false,"_links":{"self":[{"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/posts\/75026","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/users\/120"}],"replies":[{"embeddable":true,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/comments?post=75026"}],"version-history":[{"count":2,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/posts\/75026\/revisions"}],"predecessor-version":[{"id":75040,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/posts\/75026\/revisions\/75040"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/media\/75037"}],"wp:attachment":[{"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/media?parent=75026"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/categories?post=75026"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.beautydecoded.com\/en\/wp-json\/wp\/v2\/tags?post=75026"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
