This listing is a brand new/unused 0.17 oz / 5 mL size Peter Thomas Roth facial serum called "Water Drench Hyaluronic Glow Serum." This amount is equivalent to 17% of the full size bottle (1 oz) which retails for $68. The small jar would allow you to try the formula without investing in the full size. The stock photo of the full size version is shown for reference only. Check out my other "🍓5 for $15" listings, and my ‼free beauty sample listings. Thanks for looking at my closet.
