Women-owned and run solo by a Brazilian-trained tattoo artist, Beauty of Rio Studio specializes in fine-line, microrealism, and pet-portrait tattooing out of a private suite at 3594 Fifth Ave #7 in 92103 Hillcrest. Fine-line work here focuses on single-needle stippling and hair-thin botanical linework, a stylistic lane shared with other women-run Hillcrest rooms such as Goddess Temple Tattoo Studio. Pet portraiture is booked as a separate micro-realism session with reference-photo consultations, scheduled rest breaks for the artist, and session-length caps that keep linework crisp across multi-hour sittings. The studio also runs semi-permanent makeup — lip blush and microshading — parallel to the tattoo book, a cross-category offering also handled on Fifth Ave at Aaliyah's Beauty & Brows for microblading. The most detailed project on the menu is a full-arm botanical microrealism sleeve built across four to six sessions, color-mapped from a client's own garden photos and layered with single-needle pet-portrait medallions.
