How effective is laser removal for age spots on the back of the hand? | Yonsei Star Dermatology Sinchon

Hello, this is Yonsei Star Dermatology Sinchon.

When dark spots start to appear on the back of your hands, your carefully maintained hands can often look older than they are. The first question that comes to mind is usually similar: "Can age spots on the back of my hand really be completely erased with a laser?" To answer directly, the key is to accurately distinguish the type and thickness of the lesion and select the appropriate laser.

When it comes to skin care, we usually focus on our face. However, the hands are surprisingly a part of the body that often draws attention. Even if you get regular manicures and moisturize with hand cream, if dark pigment spots increase, it can be difficult to create the impression you've worked for.

Age spots on the back of the hand are common in people over 60 and are sometimes called 'death flowers'. Since they appear in noticeable areas like the face, back of the hands, arms, and legs, an increasing number of spots can give an older impression. Therefore, many people try to address them quickly before they worsen.

People often confuse age spots and lentigines when referring to dark marks. The two are similar in shape and color, making distinction difficult. Here are some simple self-check points:

• If it is raised thickly above the skin surface, it is likely an age spot.
• If it feels flat to the touch and only the color has darkened, it is closer to a lentigo.
• Lentigines are pigment changes that occur as melanin cells increase.
• If the surface is rough or flaky like dead skin, it is closer to the characteristics of an age spot.

However, these criteria are general distinctions, and we recommend confirming with a precise diagnosis at the clinic. Even if they look similar, the treatment approach may differ.

Age spots are benign skin tumors that form when the stratum corneum and epidermis thicken. To treat them, it is necessary to remove this thickened tissue. In the past, surgical methods were sometimes used, but recently, laser treatment has become established as a relatively quick way to clear them.

In the examination room, for thick age spots, carefully shaving them down with a CO2 laser is suitable, and for thin ones, a pigment laser may be applied. By combining them appropriately according to the lesion's condition, they can be cleared with little disruption to daily life. Epidermal Pigment Removal for blemishes, age spots, and freckles on the back of the hands or face is performed using this principle.

Recently, RePott Laser, which precisely treats pigment lesions, has been utilized to relatively quickly improve various pigment disorders. It can accurately target only the problematic area, allowing treatment with reduced burden on the surrounding healthy skin.

Furthermore, it is equipped with its own cooling system, designed to protect the skin during treatment and reduce pain and post-treatment redness. Cases of dull marks fading with fewer sessions compared to other lasers have been reported, and the ability to clear pigment issues before they spread further is considered an advantage. The effectiveness and number of sessions required may vary by individual.

If you have similar concerns about age spots on the back of your hand, it's best to first confirm the appropriate approach for your skin condition. Feel free to leave any questions you have via chat consultation regarding age spot laser treatment.

Even after clearing age spots on the back of the hand with a laser, brown or black pigment may remain in the treated area. While the treatment itself is complete, it is highly likely to be post-inflammatory hyperpigmentation.

As explained earlier, age spots tend to be thickly raised on the surface, whereas simple hyperpigmentation only involves a change in color. The management approaches for these two cases are summarized in the table below:

Hyperpigmentation often fades gradually over time. If you wish to shorten that period, consistently following the items below can be helpful:

• Use Vitamin C ampoules to assist in calming pigment
• Consistently apply melanin care cream
• Thoroughly use sun protection when outdoors
• If necessary, consult for a Customized Whitening Solution that manages pigment in stages

Combining additional care with laser toning can help shorten the recovery period. However, the degree and speed of effectiveness may vary by individual.

If the marks on the back of your hand reappear with a thickly raised feeling as before, it may not be simple hyperpigmentation, but rather require laser confirmation and removal of other lesions like moles, syringomas, or warts. In this case, we recommend revisiting the clinic where you received treatment and consulting thoroughly with a specialist.

Age spots are a condition that can naturally occur with age. Therefore, even if they are removed once with a laser, there is a possibility they may reappear over time. It's good to remember that it's not a one-time treatment, but rather requires ongoing skin care afterward.

For age spots on the back of the hand, it is important to approach them step-by-step: distinguishing the type, selecting the appropriate laser, and managing pigment after treatment.
