Love it!
Great serum. I’d prefer a droplet bottle. I did find the serum dries on the tip of the pump if you don’t use it everyday and dries gritty. But if you pump it, it’s a smooth serum.

Best TA yet!
This and the azeliac acid is the HG! I use this in am and the AA in pm. They are great combos to reduce age spots.

Great product
This is thick white substance unlike their other trx/niacinamide 5/5% which I loved. Not sure how this product works but will definitely update. I sing praises of this brand typically. Update ** Working well

Lightens and evens skin tone
Watery texture absorbs quickly. Noted evening of skin tone with daily use. Took months to receive.

QUALITY ISSUE
ALERT! QUALITY ISSUE The product contains granulated pieces that felt like shards of plastic pieces. I believe it’s probably crystallized chemical powder mixture this product may have used and if not stored in proper temp or correct environment it will change the chemical compound. With that said, it really didn’t do much at all except make paper cut marks on my face. I forewarning those who have very sensitive skin. Do not buy!

Probably too early to tell if it has made a difference, but will continue to use

When I use it mixed with moisturiser, it seems to reduce oiliness of skin. But in trrms of fading spots, no visible results yet and I am almost finished with the bottle.

I've been using this for a month now with absolutely no reduction in skin pigmentation. Very disappointed 😞

It’s a good product, the dark spots did fade after a couple of days using it. But, they have not disappeared after a month of usage. They are significantly lighter though. I guess laser treatment is required to completely remove dark spots .
