She might have had an off day and is still a good provider.  Has she any recent reviews that are good or otherwise?

Maybe she will give you a discounted makeup session.

I feel it is important to be truthful to other possible clients, but the fact that a bad review could hurt a person's career has to be considered too.

If you write a 2nd review on a provider, it will cause the irst review to be removed!

Just an FYI....

There is no need to get her permission or her blessing. If her services are getting worse, you should replace your old review. On the same token, it is also acceptable practice to replace a bad review with a better one if warranted.

Your new review will replace the old review and you will not get VIP credit either.

If you are writing reviews for your fellow reviewers, then change it. If you are only posting reviews for providers then you can take mrfisher's advice and beg her for better service or her permission.

Write the review! It is best to give the clients two views of the provider.
Then they can decide on their own.  The reviews should be there to help those  
Who don't know the provider and are debating whether to make a visit or not.

Of course there is no VIP credit for doing so.
