The DTSC randomly selects brands of nail polish to test for toxins that are labeled as not containing them. Recently, they discovered that several brands that claimed to not contain any toxins at all actually did contain certain ones in varying amounts. While consumers are exposed, and there is the potential for harm, the real harm lies with those who are exposed all day every day, the workers.
What does this mean for those who work in the nail field and for those who are training to do so? Basically, enjoy your job, but always remain aware of the dangers just like in any other job. And be proactive. Do not believe everything label you read. It has already been proven that they cannot be trusted. Be your own advocate and do not rely on others to do it for you.
