Introduction

Under normal circumstances, adapalene gel is unlikely to cause drug resistance, and most people can maintain its effectiveness with consistent use over several months to years. If used improperly or relied upon blindly for a prolonged period, reduced efficacy may occur, though this is not typical drug resistance. During daily use, apply a fixed amount and avoid sensitive areas such as around the eyes. Use gentle moisturizers alongside to help repair the skin barrier.

Under normal circumstances, adapalene gel is unlikely to cause drug resistance. Most people can maintain its effectiveness after using it properly for several months to several years. A reduction in efficacy may occur due to improper use or long-term blind dependence, but this is not typical drug resistance. The detailed analysis is as follows:

When used correctly, the medication works by regulating follicular keratinization and reducing inflammation, with a stable mechanism of action. Acne patients usually need continuous application for 8–12 weeks before seeing results. Following medical advice for maintenance therapy afterward, significant decline in drug efficacy rarely occurs even with long-term use, making it suitable for long-term management of chronic skin conditions.

Reduced effectiveness is often related to usage errors. For example, self-reducing dosage or stopping treatment after symptom relief may lead to recurrence of skin problems; failure to combine with moisturizing and sun protection may impair the skin barrier and affect drug absorption. Additionally, worsening skin conditions may reflect disease progression rather than drug ineffectiveness.

In daily use, maintain a consistent dosage and avoid delicate areas such as around the eyes. Use gentle moisturizers to repair the skin barrier and apply sunscreen strictly during daytime. If efficacy changes occur after prolonged use, consider adjusting the frequency of application or combining with other treatments—there is no need for excessive concern about drug resistance.

Why does my face feel dry, sting, and peel after using Adapalene Gel?

Adapalene gel is a retinoid medication used to treat skin conditions. It has a certain degree of irritation and can remove the outer layer of skin (stratum corneum), thereby achieving therapeutic effects. This irritation may also cause symptoms such as dryness, stinging, and peeling. If symptoms are mild, the frequency of application can be reduced or the medication concentration decreased. Chilling the medication prior to use may help reduce irritation.
