Which type of exfoliator is hypoallergenic?

There are exfoliating scrub products containing granules, and

When you apply and rub, it sloughs off like dead skin

You know the gommage formula?

Since most exfoliants end up being thrown away before being fully used up,

I would like to purchase only one of the two types.

I have a question

1. Which type of product is less irritating?

2. Which type of product exfoliates better?

I look forward to comments from the smart members of Unpa who can resolve my questions.
