Hello, this is Merry Plastic Surgery Clinic, always a pleasure to meet you.
Today, I’d like to talk about hyaluronic acid, which is where skin boosters begin.
You can think of hyaluronic acid as filling up the skin’s internal moisture reservoir.
Doctor, I hear there are a lot of skin booster procedures these days… where on earth should I start?
Many first-time visitors to our clinic ask this, so I thought I’d organize it in writing.
It’s probably also one of the most common questions people ask when they visit a dermatology or plastic surgery clinic for the first time.
These days, there are many different skin boosters such as Rejuran, Ellavie Retuo, exosomes, and collagen,
so let’s start by learning about the original one: hyaluronic acid!

Why is a hyaluronic acid skin injection necessary?
Why should you start with a “hyaluronic acid skin booster”?
If your skin lacks moisture from within, topical moisturizers have their limits. No matter how thickly you apply cream after washing your face, by afternoon your skin can still feel rough and your makeup may start to lift because of a lack of moisture in the dermis. Especially in spring, when humidity is low, extra care is needed. On top of that, it is still chilly, so people are using heaters too! These are the moisture thieves, in a way.
Internal dryness may be a sign of skin aging.
When the inside of the skin becomes dry, elasticity decreases and fine lines become more visible. If the oil-water balance is disrupted, sebum production can increase, leading to shine and even enlarged pores.
This is exactly when a hyaluronic acid skin booster becomes necessary.
Hyaluronic acid is one of the natural moisturizing factors (NMF), and it has the ability to attract about 1,000 times its own weight in water.
When it is injected directly into the skin, it goes beyond simple hydration and improves skin texture, radiance, and elasticity at the same time.
The four factors that determine skin quality are elasticity, texture, tone, and radiance, and this can address three of them at once.
The effectiveness of hyaluronic acid skin boosters has also been proven in studies.
It has been reported that after hyaluronic acid filler and mesotherapy, skin hydration, elasticity, and gloss improved significantly.
There are also studies showing that after hyaluronic acid injection, improvements in skin texture, reduction in fine lines, and increased radiance appeared from 4 weeks and were maintained up to 8 weeks.

In particular, the water-glow injection (a representative type of hyaluronic acid skin booster) is popular for its immediate moist feel and luminous effect right after the procedure.

Hyaluronic acid skin booster, recommended for these people
✔️ People whose skin feels generally rough and dry
✔️ People whose makeup lifts and whose pores look more prominent
✔️ People who want a safe, low-burden procedure as their first skin booster treatment
✔️ People who want to improve moisture retention within the skin, not just temporary hydration
How is it different from hyaluronic acid cosmetics?
Recently released hyaluronic acid cosmetic products include hyaluronic acid ingredients of various sizes, from ultra-low-molecular-weight to high-molecular-weight hyaluronic acid. Because the skin barrier does not allow particles smaller than 500 Da to pass through, the strategy is to allow low-molecular-weight hyaluronic acid to penetrate the skin and then block the exit route with high-molecular-weight hyaluronic acid. Therefore, if you use a product containing only low-molecular-weight hyaluronic acid, the effect may seem minimal, and if you use a product with high-molecular-weight hyaluronic acid, it may clog pores and cause problems.

Please also remember the precautions!
No washing your face or wearing makeup for 24 hours after the procedure
Avoid alcohol, strenuous exercise, and saunas for 3 days
Moisturizer and sunscreen are essential
If you receive it at intervals of 2 to 3 weeks for at least 3 sessions, you may expect better results.
If the world of skin boosters feels too broad,
we recommend starting with the most basic and essential one: the “hyaluronic acid skin booster.”
Depending on your skin condition, the product type, concentration, and treatment depth can be adjusted,
so through a consultation with a specialist, let’s create the moisture strategy that fits you best!
