Q1: Is this underwear truly suitable for sensitive skin?
A: Yes. The main fabric is made of 95% natural colored cotton + 5% spandex – 0 dye, 0 chemicals, 0 pollution. No bleach or artificial colorants are used. It is naturally soft, breathable, and non‑irritating, making it perfect for sensitive skin.

Q2: What does the negative-ion front gusset do? Will the 123 massage particles feel uncomfortable?
A: The front gusset is embedded with 123 negative-ion massage particles. Negative ions help relieve stress, reduce local sensitivity, and keep you feeling relaxed throughout the day. The particles are tiny and fully integrated into the fabric – you will not feel any discomfort, just a gentle, soothing sensation.

Q3: Is the "10A-grade antibacterial" claim reliable? How many washes does it last?
A: Yes, it has been tested by accredited labs and meets 10A‑grade antibacterial standards. It remains effective even after 300 washes – far beyond ordinary antibacterial underwear. Combined with one‑way moisture wicking, the gusset stays clean and dry.

Q4: Will the ginseng and goji berry extract wash away after a few cycles?
A: No. We use a water‑activated slow‑release technology that gradually releases active ingredients when exposed to moisture (sweat or washing water). It is not a single‑use coating. With normal wear and washing, the extract remains effective for a long time, helping inhibit bacteria and oxygenate intimate areas.

Q5: Can the graphene heat patch at the back waistband really improve blood circulation?

Q6: What is the difference between the three weaves?
A: Weave options:
Plain weave – smooth, fine texture
