Yes, the same filler can be used for both the cheeks and the under eyes, depending on what product is used. Due to advertising guidelines in Australia, we are unable to name brands, or ingredients of cosmetic injectables.
Personally, I do use the same filler for both, if the patient is young, or has good tissue coverage. If the patient is mature with a very thin skin, I will actually use different products for the cheek and under eye. It really depends on the particular patient. We are lucky enough now to have a wide selection of products to be able to choose from, depending on tissue converage, cohesiveness of the product and desired outcomes.
Best to come in and have a complimentary consultation with our experienced practitioners to see what products are right for you
