It CosmeticsBye Bye Dark Spots 4% Niacinamide Serum - Visibly Reduces Dark Spots & Improves Skin Clarity In 8 Weeks - Facial Serum with 1% Ethyl Vitamin C - For All Skin Types - 1 Fl. Oz

Wonderful! Usually allergic to everything. Product works well and no reactions. Best ever!

I use the It bye bye redness and works great. So I’m now trying bye bye spots.

I have been using this product for sometime now and I have seen a difference over a period of time. It did visibly reduce my dark spots after using regularly for more than couple of months and it works!!

I have only been using this product about 2weeksMy s un spots/age spots are still visible and have not diminished.I well continue to use it the until is bottle is empty.hopefully by then I can leave a more positive review.

I started this but then stop for a while. Just started back up about 2 weeks and I see a difference in my spots.

Used this for a few weeks (not sure how long because in all honesty I just used it not thinking it’d work)Then one day I was washing my face and could barely see the spots I’d been targeting. Ordering again to finish these little dark sun spots off my face. Will update later.I mixed this with hyaluronic acid (same brand) applied on face with special focus on dark spots and saw significant difference.

Even with avoiding my eye area it is such a harsh serum that twice after use it made both eyes and eye area swell up.

Been using this product for two years I’m 52 years old and people think I am 20 years younger true story
