I came off Yasmin contraceptive pill three years ago and since then have had the most awful back acne, I've tried no end of things to no avail, definitely hormonal as it always got worse around ovulation.
Horrible lumps under the skin that kept coming back, never came to a head and really hurt. Never mind the fact it looked bloody awful. Also used to get a bad monthly flare up on my face and down the sides of my neck and on hairline.
Over the last six weeks I have been using an application once a week of Bravura Glycolic Acid, following the instructions to the letter (lots of good reviews too and v helpful staff, answer lots of Q's by email), a bravura Dermaflannel every other day and then Salcura Antiac Spray twice a day.
Worth bearing in mind that I have followed all instructions to the t, seems to be the recommendation by all others leaving reviews too.
This seems to have made a huge difference, it's got rid of all the gunk and lumps under my skin, so it feels smooth to touch rather than bumpy, and it's also helping to fade the scars and pigmentation and smooth the skin texture over all.
The glycolic acid and and the dermaflannel work to clear dead skin cells, stimulate collagen and clear your pores. And the Salcura Antiac is an antibacterial, antiviral and anti fungal and clears the bacteria etc from your skin and deep in the pores. So works from the outside in, then the inside out.
All v good value for money, whole lot for less than £35, not full of nasty chemicals and Salcura will send you a free sample of the spray to see if it works for you.
I honestly never thought I'd get rid of this without going back on the pill (ttc now, so not really feasible, and I came off it in the first place because I'd had enough of taking artificial hormones)
I'm getting married next month and I'd even had my dress designed to cover my back as I just couldn't risk a flare up, but if it carries on like this I think it will be completely gone, plus most of the scarring. Had same great results on my face too. And confident the scarring will be gone in near future too.
I came across all three products via recommendations on MN, but the product reviews on the websites back everything up.
Good luck, I know how bloody awful it is. Especially because, like you, I had always had fab skin.
