What is the name of the model who has acted as mother in Pears soap Ad?

I'm sorry, but without more specific information or context, it is difficult to determine the exact name of the model who has portrayed a mother in a Pears soap advertisement. Pears soap has had various advertising campaigns over the years, and multiple models may have been featured in different ads. If you can provide more details or a specific advertisement, I may be able to assist further.
