The Mochi Glow Highlighter in Luna color by KAJA is praised by reviewer OLIVIA for its natural and beautiful finish. OLIVIA notes that the highlighter has a bouncy texture, which she initially thought was a joke but found to be true. She recommends using a brush for application, as using the hand alone may not provide enough product. OLIVIA emphasizes that the highlighter gives a subtle, natural glow rather than a blinding effect, which she believes is more in line with the current trend of going for a more natural look. The final look, when hit by the sun, is described as impressive. Overall, the Mochi Glow Highlighter in Luna color is a blendable and natural-looking highlighter that OLIVIA highly recommends.
