Here is a powerful ad for PSA - Make Love Not Scars. As we see a young woman give tips on how to apply red lipstick. But when you see her face is half burned, it really makes you listen to find out what it's about and as she says at the end 'you'll find red lipstick easily in the market, just like concentrated acid'.
It's a scary statement and it's definitely a strong CTA to make you sign the petition. I hope it works and please go on from this and sign to petition.
