Mandelic acid

Hello,

I can’t find this brand. I live in the UK and I would like to know if this Mandelic acid is fine

I use it ones a week for 5 weeks and after I leave my skin relax for a while. When I use this acid, I don’t use any exfoliate. What do you think?

Many thanks for your help.

Have a wonderful day and weekend ☺️
