Stretch marks are based on your skin's elasticity and how quickly you gain. Depends on your genetics. Some gain with no stretch marks, and others get tons of them with a small gain. Some topical creams help with their apoearance and may help mitigate them, but you'll have to use them at least 1-2x a day.
If you gain, you'll grow fat cells. No way around it.
