A popular pigmentation treatment that I didn't love

A lot of people claim the the Biologique Recherche skincare line is like a little miracle for your skin. I took the plunge and splurged on the lotion P50 Pigm which is made for lightening hyper pigmentation. I've always suffered from uneven skin tone and I'm willing to try anything that will help. I stuck with this product for 2 months now and I haven't noticed any changes. Unfortunately, it hasn't brightened or lightened my skin. I suppose that this product just wasn't meant for me. I'll continue using this until it's done because I'm sure it's mildly exfoliating my skin but I do have other products in my arsenal that work better for me.
