Alpha arbutin is a plant-derived skincare ingredient that can help fade dark spots. Although it is related to hydroquinone, its mechanism is different, and therefore, the time of usage varies.
While hydroquinone is often recommended for 3-6 month cycles, there's limited data indicating a definitive "stop date" for alpha arbutin. Anecdotal evidence suggests many use it consistently without adverse effects. Nonetheless, the duration of use should be tailored to individual goals. For those targeting specific dark spots or hyperpigmentation, discontinuation or reduction might be appropriate upon achieving desired outcomes to avoid potential long-term concerns.
Also, remember to use sunscreen during the daytime if you expect prolonged sun exposure.
