Removal/ prevention of facial blackheads/comedones requires simple and regular maintenance to achieve good constant results.
I always advice my patients to have:
1) A proper skin care routine, in order of: (cleanse> tone> retinoid [only at night]> moisturise> sunscreen)
2) Clinic based procedures: Customised acid peels & lasers
The above can be done in a cost-effective manner.
Hope this helps!
Cheers,
