Dermal Elasticity Care

Hello, this is Jamsilon Dermatology near Jamsil Station :)

The elasticity and radiance of your skin are not maintained by the health of the epidermis alone, which is what you see on the surface. Skin age depends on how healthy the deeper dermis is! The dermis acts as the framework that supports the skin and a storage place that holds moisture and nutrients. That is why, as we age and the dermis weakens, the skin easily sags and fine lines become deeper. So today, let’s take a look at three effective ways to care for the dermis :)

Dermal Elasticity Care

What is the dermis?

The skin is made up of the epidermis, dermis, and subcutaneous layer. Among them, the dermis is located beneath the epidermis and forms the skin’s central structure. It makes up most of the skin’s thickness and plays a key role in protecting against external impact and maintaining internal moisture! It contains various structures such as blood vessels, lymphatic vessels, nerves, sebaceous glands, and sweat glands, helping maintain balance in the skin’s overall function.

If the dermis is firm, the face looks plump and smooth. On the other hand, if it breaks down, reduced elasticity, wrinkles, and enlarged pores can appear. Especially after middle age, the density of collagen and elastin in the dermis decreases sharply, causing the skin to become thinner and begin to sag more easily. Therefore, care that protects and strengthens the dermis is the most basic and essential step in slowing skin aging.

What is the dermis?

Components of the dermis

More than 90% of the dermis is collagen. Collagen is a structural protein that firmly supports the skin, and it can be considered the key to maintaining skin elasticity and suppleness. When there is enough collagen, the skin is smooth and firm, but when it decreases, the skin wrinkles easily and loses elasticity.

In general, collagen production begins to decline in the late 20s and falls to less than half by the 40s. At this time, if exposure to ultraviolet rays, smoking, stress, and lack of sleep are added, the rate of breakdown accelerates and skin aging progresses quickly. That is why simply applying a moisturizer has its limits, and care that directly stimulates collagen or induces regeneration is needed :)

<Collagen, a component of the dermis>

  • Collagen / more than 90% of the dermis

  • Structural protein that supports the skin / maintains density / maintains elasticity

  • When collagen decreases / fine lines / reduced elasticity / sagging skin

Components of the dermis

Tentherma lifting

As the first treatment that can induce collagen regeneration in the dermis, I would like to introduce Tentherma lifting. Tentherma is a lifting procedure that uses 400W, 6.78MHz radiofrequency energy to deliver heat deep into the dermis, thereby inducing collagen regeneration. It stimulates fibroblasts in the dermis to produce new collagen and elastin! As time passes after the procedure, the skin’s internal structure becomes firmer on its own, allowing for improved sagging and lifting effects.

It also has a cooling system, so strong heat can be delivered to the dermis without surface irritation, and four differently sized tips are provided to allow customized lifting for each area. In particular, its major advantage is that it allows detailed lifting tailored to areas with different thicknesses and densities, such as the cheeks, jawline, and eye area. With consistent care, the facial contour becomes gradually more defined and the skin texture also improves smoothly.

<Tentherma lifting>

  • Minimal irritation / cooling mechanism

  • Customized treatment possible / 4 types of tips

  • Lifting / elasticity improvement at the same time

Thermage FLX

Thermage FLX is a procedure that evenly delivers radiofrequency energy to the dermis to induce collagen regeneration and tissue contraction at the same time. After strong heat contracts the collagen in the dermis, new collagen is produced during the recovery process, and the skin gradually regains its elasticity. Because it directly stimulates the deeper layers of the skin rather than the surface, a natural and deep lifting effect can be expected.

In addition, the cooling and vibration systems operate simultaneously to reduce discomfort during the procedure, and with the eye-area tip, even sensitive areas can be treated safely. Thermage FLX is characterized by a feeling of tightness immediately after treatment, followed by gradual elasticity improvement over 2 to 3 months. It is a suitable treatment for restoring firmness to skin loosened by aging!

<Thermage FLX>

  • Cooling and vibration systems / reduced irritation and pain

  • Eye-area tip / precise customized lifting possible

Collagen booster

Lastly, a collagen booster can be seen as an injectable treatment that directly induces collagen production within the dermis. Radiesse uses CaHA, a component of tiny spherical particles, as its main ingredient. It gradually breaks down in the skin and stimulates fibroblasts to help produce new collagen. Immediately after injection, it creates a sense of volume, and over time, it provides the dual effect of gradually improving skin elasticity.

Juvelook is a formulation that combines PDLLA and hyaluronic acid, inducing both collagen regeneration and moisture supply at the same time. With its regular particle structure, it is suitable for improving skin texture and maintaining natural volume, and it can also be applied to thin areas or around the eyes. By combining collagen boosters with different structures and characteristics according to the situation, you can raise both the density and elasticity of the dermis at the same time :)
