I do think the mandelic is making a difference while also being so gentle compared to other exfoliants I've used. I started using it in the morning in order to switch off with nightly retinol. I've avoided daytime use of actives in the past, but this works really well under moisturizer/sunscreen/makeup. I found that two pumps as instructed seemed like too much -- just felt like it was more likely to run off my hand and go to waste, and this stuff is too pricey for that. I like how the face wash foams and doesn't strip -- barely any is needed. I find the moisturize a bit tacky and hard to rub in, but at the same time appreciate that it isn't watery/light like many moisturizers. I'm not sure the face wash/moisturizer will be worth the price for me in the future. If this brand were to use more easily recyclable or, even better, reusable packaging, I would definitely be more likely to repurchase!
