A student from Thailand was left with an unsightly and painful scar after trying the tattoo removal process Rejuvi.

Pasuda Reaw reveals she wanted to get the large rose tattoo across her chest removed because it looked unprofessional at work. She researched several options after deciding against laser treatment.

"At first Rejuvi seemed like a good way to remove the tattoo," Reaw said of the chemical method, according to the Daily Mail, which claims to raise ink pigment to the surface with a small tattoo gun, creating a scab that can then be peeled off.

But it didn't take long for the 21-year-old to realize that something was wrong. "I began the treatment and immediately it was itchy and hurting a lot. The skin has taken a long time to come off. It was like torture and I could not sleep," she shared.

Reaw explained that when her skin did begin to peel nearly four weeks later, it left puss-filled scars that are still prominent three months after the procedure. "What is left is worse than before," she said, adding that she shared photos of her ordeal on Instagram "as a warning to others to be so careful about what they do."

Rejuvi Labs was founded by Dr. Wade Cheng, a biochemist in San Francisco, in 1988. The website states that "2-6 treatments are needed for body tattoo removal with minimal scarring risk… The treated area will initially experience erythema (redness), which will gradually diminish, leaving the skin perfectly normal."

It also claims that in the United States, an esthetician license plus Micropigmentation Training Certificate, tattooing business license, or medical license are required to purchase Rejuvi Tattoo Removal products.

We can only hope that Reaw will be able to heal after such a traumatic experience.
