Fall and winter, when UV levels are lower, are considered the ideal seasons to begin laser treatments and medical hair removal. Since UV protection is crucial after these procedures, many people choose to undergo treatment during this time of year when the sun’s rays are relatively mild. In this article, we’ll introduce laser treatments, Potenza, and medical hair removal that are recommended for fall and winter.
[Recommended Fall/Winter Treatment #1] Q-Switched Ruby Laser

Q-switched Ruby laser is,It precisely targets the melanin pigment that causes dark spots, making it easier for the body to eliminate it.. Thanks to technology that ensures uniform light delivery, it effectively treats not only age spots but also birthmarks and other blemishes.
Since you can switch the laser's intensity and mode,Can be applied to areas with thin skin. Treatments can be tailored to each individual’s concerns, targeting both the superficial and deep layers of the skin. Another benefit is that lasers that react only to melanin minimize damage to the surrounding skin.
“Post-inflammatory hyperpigmentation”—a condition in which dark spots may become darker for a certain period after treatment—is particularly vulnerable to UV rays. Since this condition is common in Japanese skin, laser treatments designed to remove dark spots are best performed in the fall and winter, when UV exposure is lower.
[Recommended Fall/Winter Treatment #2] CO2 (Carbon Dioxide) Laser

This is a CO2 (carbon dioxide) laser that can precisely target warts and moles.One of its key advantages is that thermal coagulation occurs when the surface of the treatment area is ablated, making it less likely to bleed.. Another feature is that the procedure can be performed while minimizing the impact on the surrounding healthy tissue outside the treatment area.
Also, small indentations may appear after the procedure, butScars tend to be shallower than those from surgical excision, and downtime is generally shorter.Another characteristic is that it is located there.
On the other hand, just as with the Q-switched ruby laser, you must be careful about “post-inflammatory hyperpigmentation” after the procedure. Therefore,This treatment is best suited for the fall and winter months, when UV exposure is relatively low.I suppose so. When the sun is out, we recommend using sunscreen, a hat, or a parasol. Also, please note that you’ll need to use ointment and protective tape as part of your aftercare for a while after the procedure.
[Autumn/Winter Treatment Recommendation #3] Potenza

Potenza treats acne scars, enlarged pores, and wrinkles. This treatment is also suitable for those with multiple skin concerns.A single device performs three functions: microneedle insertion, RF (radiofrequency) treatment, and drug delivery.. At Yayoi Clinic, we do not set a limit on the number of Potenza shots to ensure we can address each individual’s concerns and skin type.
The microneedling treatment performed at Potenza deliberately causes damage to the skin to take advantage of the body’s natural wound-healing process. Additionally,RF (radiofrequency) treatment stimulates collagen production.That’s right. Another feature of this drug delivery system, which delivers active ingredients to the dermis, is that it allows you to select medications tailored to each individual’s skin concerns.
Microneedling treatments like Potenza may weaken the skin’s barrier function. To prevent UV-induced skin damage, we recommend undergoing the treatment during the fall and winter months.
[Autumn/Winter Treatment Recommendation #4] Medical Hair Removal

Gentlemax Pro Plus is,A medical laser hair removal device that can effectively target unwanted hair, from thick, dark hair to fine, light vellus hair. Its unique epidermal cooling system makes hair removal possible without the need for gel. This system also helps reduce the risk of burns and pain from laser exposure. Furthermore, the device is equipped with a laser that reacts to melanin, helping you achieve smooth skin with less visible pores.
Medical hair removal is recommended during times of low UV exposure because sunburn can increase the risk of burns and may reduce the effectiveness of the treatment. Additionally, by starting medical hair removal in the fall or winter, you’ll be able to enjoy the following spring and summer without worrying about unwanted hair.
