Clio's Tinted Tattoo Kill Brow HK$179/7.3g Claim: the tattoo brow is made from DHA (dihydroxyacetone), a hypo-allergenic formula that blends colours naturally onto the eyebrows. Available in brown and soft brown, this super strong waterproof brow mascara promises not to react to sweat and water. Coffret D'or Eyebrow HK$80/5g Claim: the curved brush makes application easier and is a firm fit on the eyebrows. The long-lasting formula resists perspiration and sebum, yet washes away easily with conventional cleanser. Three shades of brown blend perfectly to match different hair colours. Vidi Vici's Perfect Eyebrow Colour Coat HK$240/6g Claim: the double-sided brush enhances the texture and colour of the eyebrow, and helps maintain healthy and voluminous eyebrows. It is available in brown and almond. Verdict: while Coffret D'or Eyebrow is the longest lasting, you need a steady hand for application since it clumps easily, creating a patchy, uneven look. Vidi Vici's Perfect Eyebrow Colour Coat is easier to use and blends well throughout. It doesn't enhance colour as much, but it makes the eyebrows look soft and natural. For those who want well-defined eyebrows, Clio's Tinted Tattoo Kill Brow is the go-to product. The tattoo side can be used to fill in sparse areas, and even out the colour by coating the mascara through the brows to create a bold, natural look.
