First of all, beauty seekers should be a little bit psychologically prepared before getting a hydrafacial. How to say? You can’t get the baby skin you’ve always dreamed of with a single injection. There are 5 reasons for this: 1. The main component of the hydration needle is hyaluronic acid, just injected hyaluronic acid in the storage of water, about 1 week to see facial hydration, reduce fine lines and other effects. 2, the skin will be anti-dry phenomenon within 3 or 4 days after playing the water light injection, this is normal. Because hyaluronic acid into your skin, will quickly grab all the water nutrition in your skin, to supplement the construction of your skin base layer. At this time, your skin surface will lack of nutrition and moisture, all skin will look anti-dry, anti-dark. 3, the skin condition is different, the effect after the injection of water light needle also varies from person to person. For example: the land that is so dry that it cracks and the land by the water, the same is poured a bucket of water, the result can be imagined. Therefore, the number of injections of hydrafacial injection varies from person to person, and is not fixed. People with average skin conditions can initially do one injection per month, with 3 to 4 times as a course of treatment. If the skin condition is not good, if the skin condition is not good, it is recommended to inject once every 2 months. The skin condition is different, the interval and number of injections are different, you need to communicate well with your doctor. 4, post-operative care is also very critical. As introduced above, there is an anti-drying period after the injection, this is because hyaluronic acid is absorbing water, this is the golden period of your skin care, hydration is the king. What you need is a sterile medical mask once a day for 7 to 10 days, and all skin care products need to be strong hydrating and moisturizing. And do not use functional skin care products and masks, such as wrinkle removal, whitening masks. 5, the effect of hydration injection is a period of time. After hydration injection, its ingredients will be hydrated with the body’s cells and eventually metabolized. Therefore, the effect of hydrating injection are limited.
