Ceyca Jewelry & Piercings in Chula Vista's Eastlake district operates as a women-owned ear-piercing studio inside Sola Salons at Otay Ranch Town Center on Birch Road. Each piercing appointment begins with on-site autoclave sterilization of implant-grade stainless steel and ASTM F136 titanium flat-back studs, a needle-based protocol that contrasts with the spring-loaded gun technique and complements the event-prep makeup work at Glam Powder Room. The studio's bilingual English-and-Spanish consultation covers anatomy-specific placement for helix, conch, tragus, and lobe configurations, with aftercare guidance tailored to each cartilage zone. Ceyca's proprietary jewelry line retails hoops, huggies, and flat-back ends in gold and silver finishes from the same Birch Road suite that anchors Chula Vista's Eastlake piercing corridor alongside hair-styling services at Gila Rut Aveda Salon. Flat-back threadless-end piercing jewelry ranges from 16-gauge to 18-gauge posts in both 316L surgical stainless steel and ASTM F136 titanium, sized for 6mm to 8mm post lengths depending on tissue depth and swelling allowance.
