I agreed with what Dr Wu has mentioned earlier. If cleanser, toner and topical creams failed to improve your condition, you probably need heat based machine to reduce the active oil glands on top of good skincare and oil control creams.
In my practice, my patients preferred below 2 treatments for oily skin.
1) Carbon laser peel - Zero down time. Suitable for mild to moderate oily skin. 1 to 2 monthly maintenance treatment is needed. The result is decent if the correct setting is used.
2) Erbium glass laser - Mild redness for 1~2 days and slight discomfort during treatment. Suitable for moderate to severe oily skin. This treatment also help with mild acne scars, large pores, fine wrinkles, tightening and resurfacing.
However, those patients who did combination treatment of lasers with skinboosters + Rejuran have the best clinical result.
Hope this helps!
