[Doctor's Column] Skin Boosters Are Not 'Moisture Injections': The Principle of Real Skin Improvement Is Separate

 

"My skin is dry, so shall I get a moisture injection?"

Many people refer to skin boosters as "moisture injections." Since hyaluronic acid is an ingredient that attracts moisture, it is easy to assume that simply injecting it into the skin makes it hydrated. However, recent studies suggest that the true effect of skin boosters is not "moisture supply," but Collagen regeneration It shows the fact that it is in.

 

▶ Q. Doesn't just replenishing moisture improve the skin?

Hyaluronic acid (HA) is an ingredient that can attract moisture up to approximately 1,000 times its own weight. Therefore, when injected into the skin, you can feel an immediate moisturizing effect.

However, moisturizing effects alone are insufficient to resolve fundamental problems such as fine lines, loss of elasticity, and rough skin texture. This is because moisture naturally evaporates over time. Skin boosters A role beyond simple hydration The key lies in doing...

 

▶ Q. What is the real role that skin boosters play inside the skin?

2007 Archives of Dermatology According to a study published in [Journal Name] (Wang et al.), injecting cross-linked hyaluronic acid into the dermis applies mechanical tension to surrounding collagen fibers, and this physical stimulation activates fibroblasts to induce the synthesis of new type I and type III collagen. This effect was confirmed to persist for at least 13 weeks after injection.

Simply put, hyaluronic acid acts as a 'cushion' inside the skin, stimulating surrounding cells. Helping to create new collagen no see.

・ Hydration → Immediate moisturization and radiance improvement
・ Mechanical tension → Fibroblast activation → New collagen synthesis
・ Growth factor induction → Dermal extracellular matrix (ECM) remodeling

2013 Journal of Dermatological Science A randomized controlled study published in [Journal Name] (Turlier et al.) also confirmed an association between collagen production and mechanical tension after HA injection. In other words, skin boosters are not 'hydrating injections' A procedure that awakens the skin to regenerate collagen It is close to.

 

▶ Q. Do ingredients other than hyaluronic acid have the same effect?

Recently, skin boosters with various ingredients in addition to hyaluronic acid are being utilized.

・PDRN (Polydeoxyribonucleotide): Promotes the regeneration of damaged cells and has anti-inflammatory effects.
・PDLLA (Polydielactic acid): It breaks down within the dermis and stimulates collagen synthesis over a long period.
・Atelocollagen It directly supplies collagen while simultaneously inducing the body's own collagen production.
・Exosomes : As an intercellular signaling molecule, it is involved in skin regeneration and soothing.

At our Yeonsinnae branch, you can receive skin boosters with various ingredients, including HA Skin Booster (LiviShine), Atelocollagen Booster (LiviColl), Exosome Booster (LiviExo), PDLA Booster (Juvelook), and PDRN Booster (Rejuran, Vitaran). Since suitable ingredients vary depending on your skin condition and concerns, we recommend making a customized selection through a consultation.

 

▶ Q. Does the effect last after just one injection?

The half-life of dermal collagen is known to be approximately 15 years (Wang et al., 2007). While collagen generated from a single treatment is maintained for a relatively long time, it is common practice to undergo multiple treatments at regular intervals initially, followed by maintenance care, to achieve noticeable changes in skin texture. As collagen accumulates with each subsequent session, skin density and elasticity tend to improve.

However, the degree of effectiveness and the duration of results may vary depending on individual skin condition, age, and lifestyle. Specific treatment intervals will be provided during the consultation.

 

▶ Lifestyle habits are also important.

To maintain the effects of your skin booster for a long time, the following habits are helpful.

・UV protection Ultraviolet rays activate collagen-degrading enzymes (MMPs), which can destroy even newly formed collagen. It is important to thoroughly apply sunscreen with an SPF of 30 or higher when going outdoors.
・Get enough sleep Growth hormone is secreted during sleep and is involved in skin cell regeneration and collagen synthesis.
・Balanced hydration and nutrition intake A lack of hydration in the body can impair skin barrier function. Foods rich in Vitamin C act as cofactors for collagen synthesis.
