由於玻尿酸具備的是抓水而非滋潤的特性，男性保養專家男研堂在運用玻尿酸作法上是添加德國高活性肌肽＋澳洲金皮萊姆萃取＋京都伏見酒糟，並添加多種獨家研萃植物“發酵液”，讓玻尿酸保濕效益最大化。
玻尿酸（Hyaluronic Acid，簡稱HA）在保養界享有「保濕神物」的美譽，被廣泛應用於保養品與醫美療程中。然而，許多人因其名稱中的「酸」字，誤以為玻尿酸類似果酸、水楊酸，具有剝離角質的功能。事實上，玻尿酸是一種天然存在於人體結締組織中的多醣體，主要成分為透明質酸鈉，pH值接近中性，不會對皮膚造成刺激。
玻尿酸如何發揮保濕效果？
玻尿酸的保濕關鍵在於其強大的吸水能力。研究顯示，每克玻尿酸可吸收多達1000倍自身重量的水分，因此成為各類保濕產品的重要成分。當玻尿酸塗抹於皮膚時，它能夠吸附空氣中的水分，並形成鎖水屏障，減少水分蒸發，使肌膚維持水潤與光澤。
大、中、小分子玻尿酸的差異
男性保養專家男研堂的創辦人及產品研發為醫學背景，提到市面上的玻尿酸產品常標榜「大、中、小分子」，不同分子量的玻尿酸，影響其在皮膚上的作用機制。
- 高分子玻尿酸（>100萬道爾頓）：停留於皮膚表層，形成保護膜，減少水分蒸發。
- 中分子玻尿酸（50萬-100萬道爾頓）：可滲透至角質層，提升肌膚含水量。
- 低分子玻尿酸（<50萬道爾頓）：據稱可進一步滲透到表皮層，但無法進入真皮層。
值得注意的是，皮膚的角質層屏障原本設計來防止大分子物質進入。研究顯示，皮膚細胞間的空隙約為500道爾頓，而即使是低分子玻尿酸，其分子量仍遠超此標準，因此單純透過塗抹並無法深層滲透。若要達到深層補水效果，需透過醫美注射方式。
玻尿酸也被廣泛運用於面膜中，在挑選時應注意自身膚質及產品中的其他成分，以及敷面膜的使用環境。
市場對玻尿酸的迷思與真相
玻尿酸作為保養品明星成分，市面上的行銷資訊真假參半，男研堂創辦人具備醫學背景，協助釐清幾個常見的迷思：
玻尿酸可以深入真皮層？
錯誤。玻尿酸分子量遠超皮膚屏障能吸收的範圍，無法透過塗抹進入真皮層，需透過醫美注射方式才能達到填充與深層補水效果。
玻尿酸分子越小，吸收效果越好？
錯誤。即便是「小分子玻尿酸」，其分子量仍超過皮膚吸收門檻，實際作用仍侷限於角質層，滲透力有限。
玻尿酸濃度越高，保濕效果越好？
錯誤，研究顯示，玻尿酸的最佳添加濃度為 0.025%~0.1%，此範圍內即可發揮良好的保濕效果。
當濃度過高時，可能反而造成肌膚缺水。玻尿酸具有極強的吸水性，若環境濕度過低，玻尿酸可能會從肌膚內部抽取水分，導致皮膚更乾燥。
玻尿酸確實在保濕上有良好效果，但挑選產品時需注意不在廣告宣傳詞中迷失，選擇合適的保養品才能有效解決肌膚缺水問題。
