Differin (or adapalene) is a type of retinoid (vitamin A derivative product).
Purging is not common with Differin use. It is more common to experience some redness, dryness, irritation, burning/stinging sensation or peeling with the initial use of Differin. Should you experience this, it is advisable to use it just 2-3x a week every night while your skin gets used to the treatment. You can also use moisturizers to calm the skin down.
Once your skin adapts to the medication, you may then increase the frequency of use to every night. Apply just a thin layer to the whole face especially to oily areas, and not just spot treatment to individual acne spot. Differin actually has better tolerability compared to other retinoid products such as tretinoin (meaning fewer side effects).
Do note that:
1. As with most acne treatments, you need to continue use for several months in order to get results with it.
2. Differin is a maintenance treatment and you should continue to use it even after your face is clear.
