Topical Retinoids

How do they work?

Topical retinoids are vitamin A derivatives that work by preventing dead skin cells plugging hair follicles and reducing inflammation.

Examples of topical retinoids used to treat acne include: adapalene, tretinoin and isotretinoin.

How are they used?

Topical retinoids are available in gels or creams, which are usually applied once a day before going to bed. 

They should be applied to all parts of your face affected by acne, 20 minutes after washing your face.

A six-week course is usually required, but you may be advised to continue medication after this, but on a less frequent basis.

It is important to apply topical retinoids sparingly, and avoid excessive exposure to sunlight and UV.

What are the side-effects?

Topical retinoids should not be used during pregnancy as they carry a theoretical risk of causing birth defects.

The most common side effects of topical retinoids are mild irritation and stinging of the skin.
