Smart Set Salon and Spa on Chula Vista's Third Avenue has specialized in permanent makeup and microblading since opening its Third Avenue Village studio in 2017, anchored by a California-licensed esthetician who trained in Seoul, South Korea. The microblading process uses a manual pen to draw individual hair strokes into the brow, producing a feather-stroke effect that lasts up to three years before fading — precision cosmetic tattooing that complements the injectable-filler work at Aventus MED SPA for clients building a comprehensive facial-aesthetics program. Permanent eyeliner, ombré powder-fill brows, and permanent lipstick expand the PMU menu, while individual lash extensions, facials, waxing, and chemical peels cover the traditional esthetics side of the operation. The 310 Third Avenue address sits in the heart of the Third Avenue Village district's salon row, near the custom body-adornment work at Sparked and Linked Permanent Jewelry for clients investing in lasting personal-aesthetic enhancements. Each microblading session implants iron-oxide pigment at a depth of 0.08 to 0.15 millimeters into the upper dermal layer using a 12- or 14-pin U-shaped blade configuration, calibrated to deposit color without scarring the surrounding tissue.
