Benefit Cosmetics BrowBar in Carlsbad operates inside the Ulta Beauty store on Calle Barcelona in the La Costa area, serving as the self-described number-one brow brand worldwide. Benefit-trained aestheticians perform brow waxing, brow lamination, brow tinting, and lip and chin hair removal using the brand's proprietary hard-wax formula, a threading and wax menu that extends the precision arch work offered at Brow Experts Threading Salon. Brow lamination at this Carlsbad location restructures brow hair with a keratin-infused perming system that holds a feathered or brushed-up shape for up to six weeks. Custom brow tinting uses a semi-permanent vegetable-based dye mixed on site to match natural hair color within one to two shades, a men's and women's service category that bridges the gap between cosmetics counter grooming and the traditional barbering menu at The Viking Men's Salon. The lamination process applies a cysteamine-based restructuring cream at controlled intervals of eight to twelve minutes to break and reform disulfide bonds in the brow cortex without ammonia or thioglycolate.
