This listing is a 0.25 oz / 7.5 mL size Perricone MD facial serum called "Cold Plasma Plus+ Advanced Serum Concentrate." Brand new, never been opened or used. This amount is equivalent to 25% of the full size jar (1 oz) which retails for $149, meaning this listing would have a value of $37. The small jar would allow you to try the formula without investing in the full size. The stock photo of the full size jar 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.
