In recent years, incorporating skincare ingredients into textile fabrics has become an innovative direction in the field of close fitting clothing. Among them, hyaluronic acid fabric has attracted market attention due to its moisturizing and nourishing effects.

Ruiyuan Technology's brand "Oxygen Curve" extensively uses fabrics containing 400 times the amount of hyaluronic acid water locking molecules in fitting underwear products, focusing on moisturizing the skin and relieving dryness when worn. At the same time, the product line has also expanded to include moisturizing fabrics rich in tea polyphenols, further enriching the selection of functional close fitting clothing.

However, the market has mixed opinions on the actual effect of hyaluronic acid fabric. Hong Kong's "Sing Tao Complaints King" once tested multiple hyaluronic acid thermal underwear purchased online in mainland China, and found that although the men's "hyaluronic acid invisible muscle bottom" has a smooth texture, its warmth rating is only one star; The women's "Hyaluronic Acid Moisturizing Clothing" performs well in terms of comfort and stretchability, receiving a four-star rating. This indicates that the experiential effect of hyaluronic acid fabric is closely related to the specific process and fabric compatibility, and not all products can balance skincare and functionality.
