Pearl Drops works in two ways to enhance, whiten and brighten your smile. The unique blend of polishing agents in the 4D whitening system accelerates whiteness and helps lift stains and plaque whilst the Pro-Shine complex and gentle pink dye gives an instant optical whitening effect and gloss, perfect for a finishing touch.
Very good product , the only negative for me was it smells so much like Flash bathroom and although I like the smell of Flash I was hoping for a different fragrance with it being a Spanish cleaner. Product works really well though and I was completely happy with the end result.
