Bumps on baby’s face and legs

I think the bumps on his face could be baby acne not 100% sure. Does that what it looks like to y’all? The bumps on his legs I’m not sure about. I use sensitive detergent, haven’t been around bugs of any kind that I’m aware of. I have been very cautious because I have a cold sore from stress and I am so paranoid now. 😭 to add he has his 1 month check up Monday so I plan on asking his doctor. Just trying to put my mind at ease by asking other mommies. ☹️
