You must use a primer to fill in fine lines and get a clean canvas. It will also make your foundation last longer.
If your skin is dry, the foundation will crease no matter how great the product is. To prevent creases caused by dryness, use a hydrating moisturiser before applying foundation.
You can exfoliate your skin once every two weeks to get a better skin texture.
Use a damp beauty blender while applying foundation and blend the product properly before moving on to setting powder.
Lastly, use a setting powder to prevent creases from forming under your eyes and forehead.
Extra Tip: Use a compact and a sponge to touch up your makeup every 2 to 3 hours.
