It Takes More Than Teint Miracle Instant Retouch Pen to Tame My Dark Circles

To sleep, perchance to dream of disappearing dark circles with the new Lancôme Teint Miracle Instant Retouch Pen ($29.50).
Lancôme calls this illuminating instrument a multipurpose foundation in a pen. Micro-fluorescent particles in the formula supposedly mimic a surge of natural light to illuminate and smooth the skin while reducing the appearance of imperfections on the face.
Brilliant! So does it work?
Well, I think that depends.
Do you adore YSL’s Touche Éclat? It looks like Lancôme does. The similarities between YSL’s award winner and the Teint Miracle Instant Retouch Pen are recognizable from a mile away — the pen packaging, the brush tip, the whole illuminating angle. It’s Touche Éclat déjà vu in a less expensive ensemble ($29.50 vs. $40 for Touche Éclat).
