(1) I want to test them all for publication, and (2) It is actually good for you to switch products. Hyperpigmentation tends to respond best when different items are used, so switching treatment actives now and then can trigger your skin to react better to them.
My latest test item has been Exuviance Skin Brightening Gel. Right off the bat I noticed something different about this gel that I really liked: The gel is thicker than most. This makes it easier to apply only to discolored areas. The gel itself is hydroquinone free for those who are concerned about that ingredient. Instead of using hydroquinone as the primary agent it includes the following:
A skin-renewing blend of anti-aging Polyhydroxy and Alpha Hydroxy Acids (PHAs and AHAs), including Glycolic Acid, Lactic Acid, Citric Acid and Gluconolactone – along with skin brighteners including Kojic Acid, Vitamin C, Mulberry Extract, Bearberry Extract and Licorice.
That is a pretty decent list of ingredients that are known to be effective skin lighteners, making this a good one to try out. I used it for several weeks in conjuction with a hydroquinone product and was perfectly happy. But effectiveness overall is hard for me to judge, simply because I do use hydroquinone in conjuction with other products and am not willing to completely give it up when testing other items.
At $25, the Exuviance Skin Brightening Gel is also one of the most affordable brightening products on the market that includes a good blend of treatment actives. So this one is a good value as well.
