Eclat de Teint By Terry (HK$540/6.5ml)
Claim: the Rose Flash pen erases flaws, smoothes out and refreshes tired features through the optical correction of skin surface texture. It can be applied onto bare skin or skin with make-up.
MAC Prep + Prime Highlighter (HK$190/3.6ml)
Claim: use the pen under, over, during and after make-up application. A sheer wash of colour to highlight, brighten and perfect.
Lancome Teint Miracle (HK$240/2.5ml)
Claim: the multi-lights corrector pen is enriched with micro-fluorescent particles for a burst of natural radiance. Illuminates, smoothes and reduces dark circles, imperfections around the nose and lips and uneven skin tone.
The verdict: the liquid in all three of the brush-based pens is dispensed with a quick click. The By Terry pen offers a light pink glow, so it's ideal for highlighting. Go easy on the MAC, which can create a Kabuki-like effect if spread too liberally. The Lancome is a happy medium.
