For about past year and a half, I've been religious about using an acid exfoliant in the form of a liquid (toner) or saturated pads twice a day. You may remember that First Aid Beauty Facial Radiance Pads made it into my 2014 Best Beauty Buys, and I still use and love them; I do think however that your skin can get used to a given acid combination, and it's important to switch things around a bit to keep seeing the result. Which is why I purchased the immensely popular Pixi Glow Tonic ($29 for 250ml/ 8.25 fl oz) when I spotted it on BOGO sale late last year.
Belly, who recommended the Glow Tonic to me, thinks the scent is a bit botanical, but it really reminds me of generic toiletries one finds in a hotel bathroom - not unpleasant though. Partially because of the added fragrance, Beautypedia gave the Glow Tonic a really low rating, reasoning that it wasn't gentle or suitable for sensitive skin, and while your personal mileage may vary, I've found the opposite to be true on my easily irritated skin. The consistency is liquid like water, and like water, it aborbs immediately with absolutely no greasy or sticky residue, which has been an issue for me with Paula's Choice BHA liquid exfoliant and the Peter Thomas Roth Un-Wrinkle Pads (reviewed here).
However, sometimes the problem with extra gentle exfoliants is that they don't actually do anything, am I right? That's fortunately not the case with the Glow Tonic. I have noticed less overall congestion and breakouts recently, and at the same time, I have a lot less surface dehydration (dry flakes and lines). This translates to a more even, glowy complexion that's also prepped well for make-up application.
What do you use to exfoliate your skin? Do you prefer gentle exfoliants used more often, or something stronger once a week? I actually do both; use my Pixi Glow Tonic in the morning and the First Aid Beauty Pads in the evening, but once a week, I dig out an exfoliating mask and follow it up with Dr. Wu Mandelic Acid Serum, reviewed here. Let me know if you have any product recommendations, I'm always on the lookout for a good chemical exfoliant!
