the ordinary expiry dates

I recently bought some products in a cheap cosmetic shop and realised that some of them were out of date. I want to buy the niacinamide and glicolic acid from The Ordinary but I can't find the expiry date! Does anyone know where it is? I've checked on the box, under the labels... On the glicolic acid there are few letters written under the bottle and that's it... I know the PAO but not the expiry date and I don't really trust that shop, so I would like to check it. Thanks!
