Hyaluronic acid (HA) has become a commonly used ingredient in topical moisturizing products; however, limitations of delivery of HA to only the surface of skin have hindered leveraging the full capacity of HA for skin rejuvenation. Here, we aimed to evaluate the clinical benefits of a multi-weight HA plus antioxidant complex-based lotion with SPF 30 compared to a single-weight HA plus ceramide-based lotion with SPF 30.
A double-blind comparative study was conducted on 70 female subjects, aged 25 to 65 years with mild-to-moderate facial dryness and visible fine lines and wrinkles, divided evenly into two groups (n=35 per group). Clinical grading of the face, including dryness, roughness, and fine lines, was assessed after once-daily application for up to eight weeks.
Daily use of the multi-weight HA plus antioxidant lotion demonstrated significant improvements in all clinical grading assessments (dryness, roughness, and fine lines) as early as Week 2 compared to baseline. Statistically significant improvements in visible dryness, roughness, and fine lines were greater for the multi-weight HA plus antioxidant lotion compared to the single-weight HA plus ceramide-based lotion.
The overall small sample size.
This study showed the enhanced improvement in dryness, roughness, and fine lines following daily utilization of a novel multi-weight HA plus antioxidant complex-based lotion compared to a single-weight HA plus ceramide-based lotion. These improvements may be attributed to the ability of multi-weight HAs to moisturize the skin surface and penetrate the upper surface layers of the skin, combined with the added benefits of key antioxidants.
透明质酸(HA)已成为局部保湿产品中常用的成分;然而,HA仅作用于皮肤表面的局限性阻碍了充分发挥其嫩肤的全部功效。在此,我们旨在评估一款含防晒系数30的多重分子量透明质酸加抗氧化剂复合物乳液与一款含防晒系数30的单一分子量透明质酸加神经酰胺乳液相比的临床益处。
对70名年龄在25至65岁、面部有轻度至中度干燥及可见细纹和皱纹的女性受试者进行了一项双盲对照研究,将她们平均分为两组(每组n = 35)。在每天使用长达八周后,对面部的干燥、粗糙和细纹等进行临床分级评估。
与基线相比,早在第2周,每天使用多重分子量透明质酸加抗氧化剂乳液在所有临床分级评估(干燥、粗糙和细纹)中均显示出显著改善。与单一分子量透明质酸加神经酰胺乳液相比,多重分子量透明质酸加抗氧化剂乳液在可见干燥、粗糙和细纹方面的统计学显著改善更大。
样本总量较小。
本研究表明,与单一分子量透明质酸加神经酰胺乳液相比,每天使用新型多重分子量透明质酸加抗氧化剂复合物乳液后,在干燥、粗糙和细纹方面有更大改善。这些改善可能归因于多重分子量透明质酸对皮肤表面进行保湿并渗透至皮肤上层的能力,以及关键抗氧化剂带来的额外益处。
