Hello 👋 

Do you think that the hyperpigmentation product can help people having acanyosis on there neck and under harm? 
What's the best option in term of routine?

acantosis negricans

The bottle is small and overall for a long treatment or multiple places  it is quite pricey . I think To have a better result you have to use it after exfoliation .
I personally layer it with niacinamide + zinc serum

Great experience. 
The product is easy to apply and don&#39;t  trigger any sensitive reaction for me
It-s kinda oily and I put it last on my routine just before the moisturizer and after the niacinamide +zinc serum from the ordinary .
The first impression are very good I have been using this for a week now and I start to see some hyperpigmentation spot getting better. 
I use it for my face and underarms
