“Why is it that, with most dermatology treatments,

it is difficult to see the desired results

after just one session?”

Many people who are beginning dermatology treatments expect to notice a visible change after receiving treatment just once.

Of course, there are treatments that can produce some degree of change after just one session.

However, treatments and procedures intended to induce changes in the skin itself—such as acne, pigmentation, or firmness—usually do not produce immediate results.

From now on, I will explain the reasons for this in detail.

For those of you who have wondered why dermatology treatments must be repeated several times, today’s post will surely be helpful.

  • Why the skin needs time to change

  • How many sessions are needed before effects appear?

  • Points to keep in mind when repeating dermatology treatments

Why the Skin Needs

Time to Change

Dermatology treatments are not performed simply by wiping away surface-level skin problems like an eraser.

Skin tissue

They are often based on the physiological process through which skin tissue responds to stimulation and repairs and reorganizes itself.

When our skin receives external stimulation, it goes through the following stages in sequence: recognition of damage → inflammatory response → recovery and regeneration → tissue reorganization.

Because this process includes changes at the cellular level as well as structural changes in the dermis, it necessarily requires a certain amount of time.

In addition, the skin is not tissue that remains in a constant state; it continuously undergoes turnover.

Therefore, please keep in mind that it takes at least one full cycle for changes made externally to actually be reflected on the skin’s surface.

How Many Sessions Are Needed

Before Effects Appear?

So, how many sessions do dermatology treatments generally require before their effects appear?

Since this varies greatly depending on each person’s skin type and the type of lesion, it is actually impossible to give a definite answer.

For your reference, I will briefly introduce the general cases by type of lesion.

  1. Acne Treatment

The number of acne treatments required varies significantly depending on the current degree of inflammation, amount of sebum, and number of comedones.

In cases of mild acne, improvement may occur relatively quickly with just two or three treatments.

However, when sebum production is high and inflammation continues to recur, consistent treatment for three to four months or longer may be necessary.

  1. Pigmentation Treatment

The number of treatments required varies depending on whether the pigmentation is limited to the epidermis, has spread to the dermis, or is associated with several other factors.

For example, when pigmentation is lightly spread only across the epidermis, many people can experience relatively quick results after just one to three laser treatments.

However, when pigmentation is mixed into the dermis, as with melasma, and is also associated with vascular and inflammatory responses, among other factors,

most cases require at least 10 repeated treatments before gradual changes can be noticed.

  1. Lifting

The treatment schedule for lifting also varies depending on the equipment used and the current degree of sagging.

When Ultherapy Prime or Thermage FLX is properly performed while taking each person’s skin type into consideration,

many people notice a change with treatment approximately once a year.

However, with treatments such as Oligio X or Onda lifting, at least three sessions are often needed to notice a meaningful change.

It should also be considered that when the loss of firmness is severe, the change achievable through laser lifting alone may be limited.

In other words, lifting should also be managed based not simply on the number of sessions, but on the characteristics of the equipment being used and

the timing of changes in the skin, in order to expect more satisfactory results.

Points to Keep in Mind

When Repeating Dermatology Treatments

Finally, I would like to explain the points I hope you will be sure to keep in mind when repeating dermatology treatments.

Structure of the skin barrier

If stimulation such as lasers or radiofrequency is repeated before the skin has sufficiently recovered, the barrier may weaken, causing dryness and redness to persist for a long time.

Therefore, please remember that repeated treatments should be performed only after allowing sufficient time for the skin to stabilize, in consultation with a medical professional.

You should also keep in mind that, rather than focusing only on the number of sessions initially planned, the treatment plan may be adjusted gradually based on the skin’s response at each session.

If the skin improves faster than expected, the treatment intensity or number of sessions may be reduced.

If the response is not as expected, the cause may be reassessed and the equipment or treatment approach may be changed.

As a result, more sessions and a longer period of time than originally planned may be needed.

Therefore, I would like to suggest that you approach your skin care with some flexibility, taking these factors into consideration.

You may have wondered why each of the recommended dermatology treatments in Mapo-gu requires repeated sessions.

You may also have been concerned that you were receiving unnecessary treatment.

However, the skin is tissue that changes slowly and gradually.

Therefore, I hope you will understand that, considering this characteristic of the skin, many treatments are designed on the premise that they will be repeated.

I hope today’s post has answered at least some of your questions. I will end here.

Thank you. This was U&I Hongdae Sinchon.^^
