Naya Rivera was distraught when she developed acne at 24.
The 'Glee' beauty - who is the new face of spot solution Proactive - admits she found having bad skin tough, but now she is "fixed" of the problem she is feeling more confident than ever.
She said: "I had really bad skin for a while earlier this year. It sort of just came out of nowhere. It was like adult acne, and I was like. 'I've had great skin my entire life. How am I dealing with this now at 24?'
"It was pretty embarrassing going to work every day and having to be on camera and having the make-up artists be like, 'Oh what's going?' My 'Glee' co-stars were really supportive. I would go around and talk about it. It was a point of insecurity for me. But I'm glad I got it fixed, I'll say that."
She also reveals she approached the company as she wanted to share her success story with the product.
She told People: "I used Proactiv and it really did work for me. It helped me out, so I got in contact with the company and told them I would love to share my story.
"So I showed them photos and they said, 'This is great.' Wait till people see my pictures. That's all I have to say. I definitely have the photos to prove [I had a problem]."
