I ordered a few things, and they should be in later this week. I was going to order the Retinol Body oil by Hand Chemistry, anyway, so I went ahead and purchased the Ordinary Retinoid 2%, NIacinimide 10%, lactic acid 5%, and RHS oil. I've tried a few Deciem products and really liked them. This new line is kind of turning the beauty industry on its head, because it's using products known to be effective, but in fairly simple formulations, and the price point is SUPER LOW. The total cost for my 4 Ordinary products was ~$32. I'm actually going to do a split face comparison over a couple of months with the Retinoid and niacinimide. I am currently using PC for both, actually at the same time bc the niacinimide has been shown to help in conjunction with the Retinoid, so I'll do that on one side, and the Ordinary on the other side. Should be interesting.
