For those of you who have tried Skin Booster, how effective is it?

I'm interested in skin boosters and have been looking into them. I'm curious about reviews from people who have actually tried them.

They say that skin boosters are good for improving skin texture and controlling oil and moisture balance, but the types of procedures offered at each hospital are so different that it's confusing.
There are so many different types of skin boosters that I can't really tell which one will be most effective.

From what I've found out, there are different types, from those that basically fill in moisture to those that focus on improving pores, elasticity, and tone, so I'm planning to get some advice.

However, I am curious as to whether the skin booster effect is immediate and how many times it takes to see the effects.
Also, I think it would be much more helpful to hear actual experiences regarding the interval between treatments, pain level, and recovery period.

My skin has recently become rough and dry, so I feel the need for more care.
Laser treatment is still burdensome, but they say that you can start using Skin Booster relatively easily.
There are also people who say that Rejuran and water glow series are especially good, but the price difference is quite large, so I am not sure what criteria I should use to choose.

If there is anyone who has tried various types of skin boosters, I would appreciate it if you could tell me the pros and cons.
I would also like to know if there were any problems after the procedure or if there was a lot of swelling or bruising.
I'm curious as to why the type of skin booster recommended by each hospital is slightly different.

Those who have actually received it, please leave a review.
It would also be helpful if you could provide some information that beginners might find helpful.
