Review on 💦 SKINCEUTICALS Hydrating B5 Gel 1.12 Oz - Ultimate Moisturizing Solution with Enhanced SEO by Kim Adams

To check the authenticity of a cosmetic product, go to checkcosmetic.net. Enter the brand name and batch code from the bottom of the bottle. The batch code is engraved on the glass and is so small that you don't see it at first and then need a magnifying glass to read it. Once you enter the code, you'll know if the product is legal and get a date of manufacture. I believe Skinceuticals products always have a 3 year shelf life and the products sold by Revain have a 2 year shelf life. It's not a problem for me as I usually use them for 6 months. Be careful with "0". Sometimes it's a letter, sometimes a number. The problem with this product, B5 Moisturizing Gel, is that it has no batch code, which means COUNTERFEIT. someone who doesn't speak English well (and is clearly dishonest). Buy direct from Skinceuticals for $83.
