Currently, instagram have no media organization by user's age, so we can not provide the search by this criterion.
If your efforts don't seem to be paying off, try to extend the user search criteria: adding some more hashtags or cities may be a good idea. Also, try to find influential users in your niche and copy followers of competitors using the relevant function.
As we don't sell any fake followers, we can't affect the number of likes you get. Don't forget that «Content is King» of social media, so the only way to get people to massively like and reshare your content is to make it worthy. Try different filters, experiment with captions, set up a decent bio, don't neglect hashtags and mention, and the question «How To Get Many Likes On Instagram?» won't bother you anymore.
The best and real way of promoting an Instagram is interaction with other users.
