It is usually recommended to do photo rejuvenation after 1 month after hydrafacial injections. Both hydrafacial and photorejuvenation can promote smooth skin and improve skin tone, but they do so in different ways. Hydrafacial injections use negative pressure needles to inject high-end injectables into the dermal layer of the skin, while photorejuvenation treats the face through intense light irradiation, where deep pigments can be crushed and broken down by the laser, eventually leading to the discharge of pigments from the body, thus achieving the function of rapid moisturization and hydration and tightening the facial skin. The main component of hydration injection is small molecule hyaluronic acid, so if you do photorejuvenation immediately, the high heat generated can lead to rapid degradation of hyaluronic acid, resulting in a waste of the efficacy of hydration injection, so it is generally not recommended to do photorejuvenation within 1 month after hydration injection. In addition, during the treatment period, you should avoid staying up late and sun exposure, eat a light diet and exercise in moderation.
