Yes, I know you will say to me: why peel tomatoes? The answer is very simple: it's much better, gives a better texture, softer in the mouth.
The skin is tough, adds nothing to the taste (and you will have noticed that commercial tomatoes have practically no taste), and finally it's there (on/under the skin) that the awful chemical products that the fruit receive during growth, are concentrated (treatments, pesticides, etc...).
