What if it slips after wearing?

Slip often results from unclean skin, improper placement, or incorrect sizing. Ensure skin is dry and oil-free. For fuller busts, position 1-2 cm higher. During exercise, choose professional styles with stronger adhesion and avoid vigorous running or jumping.

26
What is the correct wearing procedure?

1. Cleanse the chest: Wipe skin with warm water to remove sweat and oils, then pat dry to ensure skin is thoroughly dry.

 

2. Position and adhere: Identify left and right cups (larger curve is bottom, smaller is top). Apply at a 45-degree angle from bottom to top, aligning with the nipple position. Press outward to release air pockets.

 

3. Secure and shape: Fasten the front clasp, gently press edges to ensure full adhesion, and hold for 10 seconds to reinforce.

27
Can silicone bras be used for severe sagging or very small busts?

For severe sagging, choose strapped support styles as pure silicone offers limited lift. For smaller busts, opt for medium-thickness or thicker styles. When wearing, bend forward to gather the bust and use the front-fastening design to enhance lift. Note: Silicone bras do not correct breast shape.

28
What styles are available? Which occasions suit each?

Basic Silicone Style: Excellent invisibility, ideal for everyday strapless or off-the-shoulder outfits;

 

Padded Push-Up Style: 3D molded cups for shaping in wedding gowns or formal dresses;

 

Ventilated Cup Style: Breathable cup design for summer or extended wear;

 

Strapped/Side-Support Style: Enhanced lift for mildly sagging busts.

29
How to choose the right cup size?

Refer to your regular bra size: Size A fits standard AB cups, Size B fits BC cups, Size C fits CD cups. For enhanced lift, opt for one size smaller. Those with fuller busts (C cup and above) are advised to prioritize lightweight fabric-blended styles to reduce weight sensation.

30
Can those with allergies use it?

Individuals with allergies should first conduct a 24-hour skin test behind the ear or on the inner arm. Only proceed if no redness, swelling, itching, or discomfort occurs. Before wearing, ensure the chest skin is free of wounds or inflammation, and avoid applying perfumes, lotions, or other skincare products to minimize allergy risks.

31
What are the differences between adhesive types? How should one choose?

Primarily using bio-adhesive and medical-grade silicone adhesive. Bio-adhesive offers strong sweat absorption and stable adhesion, lasting approximately 3,000 uses. Medical-grade silicone adhesive is bubble-free with moderate humidity resistance, maintaining adhesion even after sweating. Suitable for most skin types, avoid adhesives with strong, irritating odors.

32
What are the core materials of the factory silicone bras? Are they safe?

The core materials consist of medical-grade eco-friendly silicone and food-grade bio-based adhesive. Both have passed EU REACH, US CPSIA, and China GB 18401 safety certifications. They are odorless, hypoallergenic, and feature a texture close to human skin, ensuring comfortable fit and compliance with safety standards.
