Good for skin
Yes!!!! This actually works but the results are not permanent you have to continue using. But it does work for while in use. Would not recommend for the face though. Or should I say do not use often on face because it makes the face so oily. And not in a good way.

It works!
This is the only lotion I’ve been using on my body. I use koji acid Turmeric soap, and I use this lotion after. I’ve had these scars for years, and I’m definitely noticing a difference. I’m sure it’ll take months to finally get clear skin, but it does work. The lather could be better, so you do have to use a lot. I wish the bottle was bigger, especially since I use it on my entire body. So I have to use a lot. A bottle only last for about a month if your using it on large parts of your body. The smell isn’t bad at all, and it’s very lightweight. It doesn’t feel super moisturizing, but it’s good to SOLEY treat dark marks, but not your average everyday moisturizing lotion. But you can see a slight difference on my legs, and other parts have been clear very well. This is a great product, for a great price. I highly recommend pairing with a soap that treats dark spots.

Different package
I have been using this product for almost two years, and I absolutely love it, especially because I have very dry skin. It leaves my skin feeling extremely soft and well-moisturized even the next day. Over time, I also noticed that my dark spots started to fade. It is a great product, but it does take time to see results with dark spots. Yesterday, I ordered the same body lotion, but it arrived with a different packaging and formula. I was afraid it might affect the progress I’ve made with my skin, so I returned it and requested the original version I’ve been using.

Scent is off putting.
Seems to be a nice lotion but for me, the aroma is off putting. That makes it hard for me to use on a consistent basis. It is moisturizing and not greasy. It absorbs well into my skin. I wish it were fragrance free. My spots are still with me but that’s my fault.

Get the combo!
Mix these 2 together and thank me later. I wish i had done before and after pics but this combo lightened my knee caps, underarms and bikini area so fast! I haven’t used deodorant in 3 days because of the lotion! It’s that effective I’m about to order 4 more bottles
