Hello,
Welcome to healthcare magic.
I understand that your son has acne and has been put on oral doxycycline.
It generally takes 2-4 weeks for doxycycline to show results in the form of controlling acne. If it has helped him in the past, he could probably wait 2 more weeks before shifting to another drug.
However, doxycycline is associated with photosensitivity. It could make the skin prone to redness and burning on exposure to sunlight. This could be the reason for the redness of his skin. Though it is less common side effect compared to tetracycline, it is still a known side effect of the drug.
I suggest that he uses a gel based , broad spectrum sunscreen every 4 hours and avoid direct sun exposure between 10 am to 4 pm. If this does not seem to help, he could consider alternative anti-acne medications like oral Azithromycin or just topicals alone.
Steroids will not help acne and can cause acneiform eruptions. So please do not use steroids of any sort.
Hope this answers your query.
Take care.
