I've personally seen several influencers try this route ("Hi, I'm a mommy influencer and I'm so excited to launch my prenatal gummy line" or "I'm a fitness influencer, and this is my new line of supplements") and it turns followers off.

We want to feel like your friends, not be treated like a captive audience of loyal, thoughtless buyers. The advertising works best when it's subtle (I'm going to post a picture on my Peloton bike), much less so when it's overt (here is my subpar whitelabeled product / you should definitely buy this Stanley, make sure to use my affiliate link!)
