Is adapalene effective?
Topical retinoids like adapalene have been used to treat acne for over three decades, and are clinically proven to be effective. A study involving 2,141 people who were either given adapalene 0.1% lotion or placebo for 12 weeks revealed that adapalene was significantly better at reducing total, inflammatory, and non-inflammatory lesions than placebo. Adapalene was also found to be well tolerated, with reports of irritation in the adapalene group being mostly mild or moderate – and people found it easy to use.
Will adapalene make acne worse?
When you first start using adapalene, there’s a chance your acne can get temporarily worse. But sometimes things have to get worse before they can get better. This reaction is sometimes referred to as an “adapalene purge”, and typically starts after about a week of treatment.
As adapalene works to exfoliate and clear your top layers of skin, clogged pores in deeper layers are brought to the surface, which can cause acne symptoms to temporarily worsen. But after these clogged pores are cleared, you should notice your acne symptoms improving. Adapalene purges usually end within four to six weeks of starting your treatment.
Adapalene can also cause something called retinisation. As your skin adapts to the medicine, it can become dry, irritated, and develop more pimples, whiteheads and blackheads for a period of time. The good news is this typically improves after around four weeks of treatment.
