Adapalene is a third-generation topical retinoid used in the treatment of acne and skin cell regulation.
Adapalene is a topical retinoid - a type of skin-care ingredient that helps the skin renew itself. It works mainly on the outer layers of the skin, encouraging the shedding of dead cells and preventing them from clogging pores. In Hong Kong, adapalene is most commonly found in the gel formulation marketed under the name Adapalen.
The principal product that carries adapalene in Hong Kong is Adapalen gel. It is supplied in two strengths: a 0.1 % gel and a 0.3 % gel. Both versions are packaged in tubes for easy application. While Adapalen is the brand name most patients encounter, pharmacists also dispense generic versions of the same active ingredient, which are simply labelled “adapalene gel” and contain the same concentration. The medication is available over the counter in pharmacies and can also be obtained via a prescription, depending on the strength chosen.
Adapalene is primarily used for skin conditions that involve clogged pores and inflammation. The most common uses include:
Although these are the main approved uses, some clinicians may recommend adapalene for other types of oily or uneven skin texture, but such applications are considered off-label and depend on professional judgement.
When applied to the skin, adapalene promotes the natural exfoliation process. By encouraging skin cells to turn over more quickly, it prevents the buildup of dead cells that can block pores. This smoother turnover also reduces inflammation, which is why acne lesions tend to improve over several weeks of regular use. The effect starts to become noticeable after a few days, but the full benefit usually appears after consistent application for a few weeks.
These effects are generally short-lived and lessen with continued use.
If any of these symptoms arise, stop using the product and seek immediate medical attention.

Store Adapalen gel at room temperature, away from direct sunlight and moisture. Keep the tube tightly closed when not in use. Treatment duration varies: some people use adapalene for a few weeks to manage a breakout, while others incorporate it into a long-term skin-care routine. Remember that each product containing adapalene may have different instructions, so always follow the guidance printed on the individual packaging. For detailed usage, dosing, and administration, refer to your specific medication’s information.
