If you're able to breastfeed the baby then it will benefit the babies health in many ways.
The natural breast milk that comes from the mother's breast is the best milk for your baby and is much better than formula.
And yes breastfed babies do tend to get less acne later on in life than formula fed babies do and breastfed babies also have a better immune system.
Breast Milk is the best milk and food for your baby and can help promote brain health as well.
If you don't want to actually breastfeed the baby you can pump breast milk into baby bottles using a breast milk pump and then store the excess milk in the refrigerator until ready to use.
Your baby will be much healthier when breastfed or drinking breast milk and they tend to spit up less as well.
