Personal advice is better to find an expert at your own expense. After all, it is appearance. Maybe children will feel inferior when they grow up. My eldest son made it three and a half years ago, and now it is in the middle of the children's class! The effect is quite good, but it is only a unilateral cleft lip, which cost more than 10 thousand points at that time. I think the free effect is not good. I heard that many of them were done by interns.
