Key Ingredients
多層ヒアルロン酸（7種）
7种不同分子量透明質酸。高分子HA在肌肤表面形成屏障，低分子/纳米HA渗透至角質層深部。
乳酸球菌/ヒアルロン酸発酵液
发酵技术制备低分子透明質酸，渗透性約为传统产品2倍。
How It Works
透明质酸是葡萄糖醛酸/N-乙酰氨基葡萄糖二糖重复单元组成的糖胺聚糖，保持自身约1000倍水分。高分子HA在表皮形成粘弹性膜降低TEWL。中分子HA渗透角质层上层。低分子/纳米HA到达角质层深部。多层方法同时实现即时保濕感和持续深层保濕。
How to Use
潔面和化妆水后，取2-3滴于掌心，在微湿肌肤上按压渗透。避免在干燥肌肤上使用。使用后务必用面霜或精油锁住水分。
Expected Results
即时肌肤饱满、保濕感显著。1-2周干燥细纹不明显。4周以上角质层含水量持续提升，屏障功能强化。

異なる分子量のHA配合クリームの抗シワ効果を比較。低分子HAほど深部への浸透が優れ、高分子HAは表面保護に優れることを実証。
Precautions
乾燥环境（湿度<40%）下HA可能从皮肤吸水。务必用面霜/精油锁水。常温保存避免直射日光。
