Of all the microdermabrasion-esque scrubs I’ve tried (approximately 10, ranging from high end dermatologist branded to drugstore chic range) this had the quickest efficacy. Immediately after I used it in the shower, I was able to see visible brightening and renewal on an overall, but nothing specifically for discoloration or spots. That was just my first look when I stepped out of the shower. It made my skin perfectly prepped for my nighttime routine and skipped the toning just because I didn’t want to aggrevate the baby day-1 skin that I revealed post-pat dry. The products went in smoother and this scrub made me feel so fresh, not just my face, but my whole vibe! I did use the scrub as a spot treatment on a couple other areas on my body while I was showering. Anyway, in the days following my scrub i can attest that this product for sure increases the effectiveness of other skin care products and makes your skin more sensitive to them, as well. So whatever you use, just use a little less or maybe even cut out a product or two just because you don’t want to inadvertently irritate your new baby day-1 skin with too many products. So for me, since I was @ the tail end of a pre-menstrual caused breakout, I skipped toning on night 1, but applied La Mer lotion, a drop of eye cream, and MB buffing lotion and drying lotion on active spots. Next morning I wiped my face with bio Derma micellar water and applied la mer mattifying lotion and my skin looked better than it’s looked in a while. Fine lines were gone, better and more even toned, and overall brightness increased. Dark spots were less pronounced and some of the less intense ones were gone pretty much. So I’m not sure if this product was the miracle worker or if this product just made it possible for my existing products to work their miracles, but either way, it was essential to the magic. I recommend it if your skin care products are already lit, if so, your face will thank. If your products are shady then I don’t think this product will do anything on its own.
