Highly recommend the Neutrogena Hydro Boost Hyaluronic Acid Serum with SPF 50! I think I paid around $12.99 for it on Amazon. I usually use their Healthy Defense SPF moisturizer ($38 for 3- great deal) but if you’re looking to spend less the Hydro Boost has been wonderful.
Also just want to say I’ve never had any issues ordering these specific products from Amazon. They are shipped and sold by Amazon which is the important part. I’d avoid any other sellers when it comes to skincare just to be safe. I used to work for a third party fulfillment company- where we bought the stock and shipped it to Amazon- and there’s just too many variables at play. They typically try to get product for as cheap as possible, the warehouses they store them in aren’t climate controlled, and there’s multiple shipping trips on trucks before it even gets to Amazon’s warehouse.
Edit: The price on the Hydro Boost seems to have gone up to $17.99 even though I bought it for $12.95 on 4/20. Maybe something to keep an eye on in case the price goes down again.
