If you have combination skin, different areas of your skin require different treatments. However, it’s easier said than done. How do you draw the line between oily and dry skin? Where exactly do your T-zone ends and normal or dry areas start? Sounds like a recipe for OCD.
The quick and easy way to deal with this is to ditch all harsh or abrasive cleansers and alcohol-based astringents – they will do more harm than good anyway. Once you are done with these, you can safely pick the product that is suited to the oiliest area. For most people it will be oily skin products (for some it will be normal skin products) and use it for your entire face.
This will treat oily areas and will do no harm to normal and dry skin. Remember, you should eliminate harsh products first.
If your dry skin feels like it needs a little more moisture, simply apply more moisturizer.
