Director Choi Woo-hyuk

 

 

Hello, this is Director Choi Woo-hyuk.

 

Laser hair removal is an effective method of hair removal using laser technology. In this column, we will discuss in detail the precautions, principles, and tips to maximize the effectiveness of laser hair removal.

 

 

1. Precautions before laser hair removal

✔️ Waxing and hair removal prohibited: Avoid waxing or other hair removal methods 4 to 8 weeks before the procedure. Since hair that has been removed cannot serve as a heat energy conductor, the effectiveness of the treatment will be reduced.

✔️ Effectiveness only on specific hair: Laser hair removal is effective only on dark hair. It does not respond to white hair, so it is better to undergo the procedure when you are young.

✔️ Avoid UV exposure: Be careful not to expose your skin to sunlight before and after the procedure. The darker the skin, the higher the risk of burns.

✔️ Shave in advance: It is recommended to shave before the procedure to keep hair short. Long hair can cause burns or damage to the device.

✔️ Post-treatment procedures for skin conditions: If you have skin conditions such as folliculitis or acne, treatment must be completed before the procedure.

 

 

 

 

2. Precautions after laser hair removal

 

✔️ Taking medication and applying ointments: After the procedure, you should use the prescribed medication or ointments from the hospital to prevent inflammation and pigmentation.

 

✔️ No hot baths or saunas: After the procedure, avoid hot baths or saunas to protect the skin.

 

✔️ Blister caution: If blisters form after the procedure, they may be superficial burns, so it is advisable to visit the hospital immediately.

 

✔️ Sunscreen is essential: To prevent excessive melanin production after skin damage, it is crucial to use sunscreen.

 

✔️ No alcohol or smoking: Alcohol and smoking can delay recovery, so it is recommended to refrain from them for at least 1 to 2 weeks after the procedure.

 

 

 

 

3. Principles of Laser Hair Removal

Laser hair removal destroys the cells that produce hair using a laser. In this process, the selected wavelength, intensity, treatment interval, and the meticulousness of the practitioner play important roles.

 

 

 

4. How to maximize effectiveness

✔️ Pre-procedure shaving: Shave the hair one or two days before the procedure to facilitate heat transfer.

✔️ Do not use waxing or depilatory creams: To maximize effectiveness, waxing or depilatory cream use should be prohibited before hair removal.

✔️ Choose an experienced hospital: Hospitals that are too inexpensive may have lower quality procedures, so it is important to select an experienced hospital that can customize treatment based on the condition of the hair.

 

 

 

 

Laser hair removal is a procedure that can yield highly satisfactory results if properly prepared and managed. Be sure to understand your skin type and hair condition well, and undergo the procedure safely through thorough consultation with a professional.
