FIXDERMANigrifix Cream for Acanthosis Nigricans with Lactic Acid | Dermatologist Tested Retinol Cream | Useful for Dark Body Parts like Neck, Ankles, Armpits & Elbows –3.52 FlOz

This cream really works, but it has to be used correctly. I’ve seen some people post pictures showing irritated or burned skin, but that usually happens because they didn’t follow the instructions or didn’t protect their skin from the sun.Nigrifix has strong ingredients like salicylic acid, glycolic acid, and lactic acid. These help remove dark spots, clear dead skin, and make your skin look better. But they also make the skin thinner and more sensitive to sunlight.That’s why it’s best to use this cream only at night before going to bed.If you use it in the morning (which I don’t recommend), then you must use sunscreen right after to protect your skin. If you don’t, the sun can cause redness, irritation, or even burns.Also, if you work indoors, it’s usually not a problem.But if you work outside under the sun, using sunscreen is a must to avoid damage.Some people have this skin condition on their forehead. The instructions don’t say if it can be used there, but yes, it can — as long as you apply it only to the affected area and not too close to your eyes.In short, this product works great if it’s used correctly. If you use it every day and follow these tips, you’ll probably start seeing results after about 3 weeks.

It gave me these rashes on the side of my neck which I never had before. It made it worse, I did have rashes on my neck where it folds but it made it worse and started getting these black rashes all over my neck all the sudden a week after I started applying this cream.

For me, this stuff's working miracles. I'm insulin resistant, had developed acanthosis on the back of my neck and was super self conscious abt it. Within just a few days I've noticed incredible results. HOWEVER, be careful if you have sensitive skin, or sensitivity to tea tree oil. Seems like every review is either "great!" or "peeled my skin off".One of the main ingredients is urea, which can be an irritant for sensitive skin. It also has tea tree oil (which I'm pretty sure is where most of the scent comes from), which can also cause irritation dryness and rashes, and since it isnt a common ingredient, you may also be allergic and not know. I'd reccommend doing a test patch for a 2-3 days, before fully committing to slathering it on your affected areas, especially if they're in sensitive regions. If still worried, try doing it only once a day instead of the reccomended twice to see how those areas react. You also do not need as much as you may think! A little bit goes a long way, and leaving excess urea and tea tree oil just sitting ON the skin might promote some of those adverse reactions, use as little as possible and rub it all in!If it continues progession at current rate, my neck will be clear within a month of recieving the product, if not sooner. Definitely worth a try if youre looking for solutions :^)

The ingredients are very good but maybe they are somewhat strong for the skin especially if you don't put sunscreen, in my case I only use them now on knees and non-exposed areas and that don’t rub skin because after a month of use I got an eczema in some areas most likely as a result of the application of the cream in my skin

This cream is very good for dark elbows and knees. Very happy with this product.

Llevo usándolo más de un mes y no veo que me haga nada

Used on the back of my neck mostly twice a day. If not at least once a day for 6 months, might not work on Black skin.

Honestly had issues with dark marks on the back of my neck and following the instructions for the cream you can see the difference in just a couple days. It's as simple as putting it on in the morning and at night. Very effective.
