Ashleigh Wild, 22, from Poulton, Lancs, began using the drug, which has been linked to depression and suicidal thoughts, six months ago.
The medication is prescription only and is heavily monitored by doctors following studies that found one in five people were affected by the side effects.
The model first opened up about her problem skin in September, when she shared a bare faced selfie with her Instagram followers.
Captioning the snap she wrote: “Unless you’ve suffered with acne, you won’t understand how much it can affect you, both mentally and physically.
“From not being able to touch my face without it hurting, to not wanting to leave the house in fear I’m ugly, my acne has took over my life (sic).
“After trying everything on the market and receiving a message off a troll about the state of my skin, I’ve finally took the plunge and started Roaccutane.
“For years I have put off this medication because of how strong and potent it is, but after seeing the results that come after the side effects, it was a no brainer.”
She finished her post by pleading with her followers to “be kind, always.”
Ashleigh has now completed her treatment and has just returned from competing in at the Miss Global pageant in Mexico.
After years of trying various other drugs and even resorting to natural remedies Ashleigh, who has suffered from acne from the age of 12, took the plunge.
Despite initially having doubts about the medication she now describes it as “the best thing she’s ever done.”
What us Roaccutane and what are the dangers?
But young men claim it has left them unable to have sex and parents believe it led their children to take their own lives.
Warnings about depression and other psychiatric side-effects were added to the drug’s patient information leaflet in 1998.
A new warning was added two years ago to say some people may struggle to maintain an erection and suffer lower libido.
The NHS says Roaccutane is only recommended for severe cases of acne that have not responded to other treatments.
They acknowledge there have been reports of mood changes while taking the drug but say there is no evidence they were caused by it.
Roche said Roaccutane is a prescription-only medication that should be used under the care and supervision of a doctor.
The firm said the majority of users have positive experiences and research had not established clear links between the drug and psychiatric disorders or sexual dysfunction.
There is a chance that Ashleigh’s acne could return but if that’s the case she will take another course of Roaccutane for a “short period of time.”
Speaking to Femail of the results, delighted Ashleigh said: “Throughout my whole treatment I barely wore make up because it was me embracing me.
“Those suffering with acne, don’t let it knock your confidence because everyone suffers with something and whether it’s acne or mental health or other things I always say some people have allergies some people have acne it’s just part of you.
“If I can give a message to them and let it be passed on that’s my goal.”
Ashleigh took home the Miss England title in June last year but the UK withdrew from the competition when it was held in Venezuela amid the country’s crisis.
