Combo skin can be a bit of a handful, right? It's like your skin can't make up its mind! 
Use products that are light but provide moisture where needed. Cleanse with a gentle face wash and use a balancing toner. 
Focus oil-free products on the T-zone (forehead, nose, and chin) and use richer moisturizers on dry spots. Finding that perfect balance can really help you get that clear and glowing look.
