Whilst epilation is an effective method of hair removal, unlike waxing, it does not exfoliate your skin.
The upside is that you don't feel the raw tenderness that comes from waxing, but the downside is that when the weaker hair grows back, it may have difficulty breaking through the skin's surface and become ingrown.
Epilators can be used dry or wet. It's recommended to start with one that can be used in the shower as warm water helps to loosen hair follicles which helps the process.
If you're going to epilate, exfoliation is key! Make sure you exfoliate (use a scrub, mitt or dry skin brushing) before you epilate to remove dead skin cells and it's good practice to exfoliate 2 to 3 times a week. Before dry epilating, brush legs with a towel to help life hair at the root to ensure a perfect finish.
Try and soak in warm water for at least 10 minutes before removing hair. This helps to open the hair follicles so the hair is loosened and comes out more easily.
