IPL (Intense Pulsed Light) is a technology commonly used for hair removal, skin beautification, and treatment of skin problems (e.g., acne, pigmentation). There are several key steps and things to note when using an IPL device:

1. Preparation
Cleanse your skin: Before using IPL, make sure your skin is clean and free of makeup or oil.
Shave: If there is hair in the target area, use a razor to shave it first. IPL only works on hair follicles, so it should not be used on areas with hair.
Avoid sun exposure: Avoid sun exposure or using tanning equipment 2-4 weeks before treatment.

2. Device settings
Choose the right light intensity: Adjust the light intensity based on your skin type and treatment purpose. Most devices have different intensity settings that you can choose based on your comfort level.
Choose the right treatment mode: Different IPL devices may have different modes, such as hair removal, skin beautification, anti-aging, etc. Choose the mode that suits you best.

3. Procedure
Apply cold gel (depending on the device): Some IPL devices may require the application of cold gel to help the light penetrate the skin and reduce discomfort.
Light source contact with skin: Aim the treatment head of the IPL handheld device at the skin. It is usually necessary to press the device gently to ensure that the device is close to the skin.
Flash operation: Press the start button of the device and the light will be released to the skin in the form of pulses. Each time you operate, you can treat a small area and gradually cover the entire treatment area.

4. Post-treatment care
Moisturizing: Use a mild moisturizer to help the skin recover and avoid dry skin.
Avoid sun exposure: Avoid direct sunlight within 24-48 hours after treatment. It is best to use sunscreen to protect the skin.
Avoid irritating products: Temporarily avoid using irritating cosmetics or skin care products (such as products containing alcohol or fruit acid).

5. Treatment cycle
Regular use: According to the MLAY product instructions, the treatment of each part generally needs 4-6 times, with an interval of 1-2 weeks. The effect will gradually appear after each treatment.
