You should incorporate anti aging products asap! It's easier to prevent than to fix. That being said all products are not created equal. Anything w antioxidants would be highly ineffective in jar as they oxidize and become ineffective ie vitamin c so packaging should be stable. There are only a few known anti aging ingredients and this Olay product has 1: vit A derivative retinyl palmitate, the least strong derivative.. aka a lesser retinol. Otc-wise it is about as good as it gets.I'd look for anything with a form of retinol. Niacinimide to reduce hyperpigmentation, peptides also have proven efficacy.
