This is a procedure note for Spots cannot be resolved with removal ointments. Why do you need laser treatment? at Beomgye(Opening Soon) KKEUT Korean Clinic.
Many people expect that applying an age spot removal cream will lighten the spots.
Whitening creams and ointments are abundant on the market and readily available at pharmacies or online, naturally leading to the idea of 'let's try an ointment first.'
To state the conclusion first, age spot removal creams are ineffective for age spots (solar lentigines).

There's a depth ointments can't reach
Age spots are pigmented lesions caused by excessive accumulation of melanin pigment in the epidermal basal layer.
The problem is that this melanin is located not on the skin's surface, but in the lower epidermis, and in some cases, even extends to the upper border of the dermal layer.
The active ingredients in ointments or creams have limitations in penetrating the stratum corneum of the skin.
Whitening ingredients like hydroquinone, arbutin, and niacinamide work by inhibiting melanin production or gradually breaking down existing melanin, but they don't have the power to completely eliminate deeply embedded pigment clusters.
Even after applying ointment for several months, all you might see is a slight brightening of skin tone, while the age spots themselves remain unchanged.

The fundamental reason laser works for age spots
Lasers operate on a completely different principle than ointments.
They directly deliver light energy of a specific wavelength into the skin to destroy melanin pigment.
During this process, the principle of 'selective photothermolysis' is at work, selectively destroying only pigment cells without affecting surrounding healthy tissue.
The most suitable wavelength for age spot removal is 532nm.
The 532nm wavelength is the spectrum where melanin absorbs light energy most efficiently, concentrating energy delivery to the pigmented lesions.

The laser used at Ggeut Korean Medicine Clinic operates with a 532nm wavelength, primarily targeting the epidermis.
Since age spots are epidermal pigmented lesions, this perfectly matches the epidermis-focused characteristic of 532nm.
Ggeut Korean Medicine Clinic's unique operational approach is to provide the same effectiveness at a reasonable price, utilizing the same wavelength principles as expensive age spot lasers like Re-Pott or Ruby series.

Do not proceed with laser treatment without a diagnosis
Not all pigmented lesions that appear to be age spots should be approached in the same way.
Age spots, freckles, seborrheic keratoses, and melasma may look similar in color, but their depth and characteristics differ.
Incorrect approaches can worsen hyperpigmentation or lead to repeated treatments due to lack of effectiveness.
At Ggeut Korean Medicine Clinic, after imaging the skin with a MarkVu diagnostic device, the director personally differentiates the lesions.
We accurately distinguish whether it's an age spot, freckle, or seborrheic keratosis before deciding on the treatment direction.

This process is not just a preliminary step before treatment, but a crucial stage for creating safe and effective results.
The results are distinctly different between proceeding with laser treatment without a diagnosis and determining the treatment direction after a diagnosis.

Post-treatment care should also be different
After age spot laser treatment, some places recommend applying DuoDERM gel or occlusive dressings.
Ggeut Korean Medicine Clinic does not use DuoDERM gel after age spot laser treatment.
The reason is clear: age spot laser treatment does not create surface wounds.
Since laser energy is delivered to the pigment while the skin surface remains intact, there is no situation requiring wound dressing.
On the contrary, applying DuoDERM gel can create a sealed environment, potentially causing irritation.
Ggeut Korean Medicine Clinic provides only post-treatment care that aligns with the nature of the procedure.

Frequently Asked Questions
Q. If I apply age spot removal cream for a long time, won't it eventually disappear?
A. The whitening ingredients in age spot removal creams help inhibit new melanin production, but they don't have the power to remove existing pigment clusters. Deeply formed pigmented lesions like age spots must be directly destroyed by laser to be removed.
Q. Is laser treatment more painful than using an age spot removal cream?
A. The 532nm laser is a wavelength that only acts on the epidermis. It does not stimulate deep tissues, so the pain burden is not significant. At Ggeut Korean Medicine Clinic, we thoroughly check the pre-treatment condition before adjusting the energy intensity.
Q. I'm not sure if it's an age spot or melasma, can I get laser treatment without a diagnosis?
A. No, you cannot. Although age spots and melasma may appear to be the same type of pigmented lesion, the approach to treatment differs. Using a high-output laser on melasma can actually worsen hyperpigmentation. At Ggeut Korean Medicine Clinic, we photograph the lesions with a MarkVu diagnostic device and the director personally differentiates them before deciding on the treatment direction.
Q. Can lentigo be removed in one laser session?
A. Lentigo may require one or several treatment sessions depending on its size and the depth of pigmentation. Many patients come to us after spending several months on lentigo removal creams, but approaching it with a laser can achieve results in a much shorter time.

The Sincerity of KKEUT Clinic
KKEUT Clinic precisely distinguishes between lentigo, blemishes, and seborrheic keratosis through MarkVu diagnostic imaging and direct assessment by the director, then determines the treatment approach.
KKEUT Clinic uses a 532nm wavelength laser, which has the highest melanin absorption rate, to precisely target epidermal pigmented lesions, providing results unattainable with lentigo removal creams.
For treatments that do not cause surface wounds, KKEUT Clinic avoids unnecessary dressings and provides only post-treatment care tailored to the essence of the procedure.
