Leaving one of these pads on a dark spot for ten to fifteen minutes is the use that comes up most in praise, and several gurus say it helps fade hyperpigmentation. Others take a harder line, warning that daily pad use can irritate skin and that the product will dull the skin. Some would rather reach for a serum or toner, since pads waste more product.
