01How Many Sessions Are Needed for Permanent Hair Removal?
Key Points: The number of sessions required for permanent hair removal varies depending on the body area, hair thickness, color, and growth cycle. Generally, the harder, lighter, or longer the hair growth cycle, the more sessions are needed. The underarms typically show the best results.
Usually, laser hair removal sessions are spaced 4 to 8 weeks apart to allow new hair to grow before the next treatment.
Hair Removal Effectiveness by Area: Underarms > Bikini line > Limbs > Hairline > Beard > Lips.
Below is the general frequency of hair removal for different areas. However, due to individual differences and varying expectations, the number of sessions can be adjusted accordingly.
02 Laser, Icepoint, and IPL Hair Removal: How to Choose?
Key Points:
- Laser: Concentrated energy with strong effects, suitable for those with thick body hair who want quick results and can tolerate some pain.
- Icepoint: Equipped with a cooling system, ideal for those sensitive to pain.
- IPL: Combines skin rejuvenation with hair removal, suitable for delicate and sensitive areas.
- What’s the Difference Between Laser, Icepoint, and IPL?
All three are essentially laser-based treatments but focus on different aspects. However, the difference in hair removal results is not significant.Tips: Some IPL devices for skin rejuvenation also have filters for hair removal, and some institutions may use IPL devices for hair removal.
03 Common Medical Hair Removal Devices
There are many hair removal devices on the market, and their actual effectiveness is not significantly different. For a more comfortable experience, you can choose icepoint devices such as Foton Icepoint, Icepoint Snow Skin, CoolSnow, Supreme, and Mancani.
- Hair Removal Speed:
Supreme > Mancani = Moonlight Vacuum > CoolSnow = Foton Icepoint = 808 > Powder > Icepoint Snow Skin.
CoolSnow uses a new floating handle to avoid cross-infection risks and improve hair removal speed. - Number of Treatments:
CoolSnow requires fewer sessions, typically 2–3 sessions for the bikini line and hairline. Underarm and limb hair removal sessions are also reduced. - Skin Rejuvenation Effects:
German Powder > Moonlight Vacuum > CoolSnow > Supreme.
04 Home vs. Medical Devices: How to Choose?
Key Points: If you can use a home device at least 1–2 times per week and stick to it long-term, a home device is suitable. Otherwise, opt for monthly medical hair removal sessions, which usually achieve permanent results after 3–6 sessions.
Home devices work on the same principle as medical devices but have lower energy levels for safety. Therefore, the treatment cycle is longer and requires consistent use.
Advantages of Medical Devices:
- Operated by professionals, ensuring safety.
- Stronger laser energy with targeted effects.
- Permanent results are typically achieved in 3–6 sessions.
05Which Home Hair Removal Device Works Best?
- Choose devices with an energy density of 5J/cm² or higher for effectiveness.
- Wavelengths between 510–1200 nm are effective, with longer wavelengths providing better results.
- Flat light-emitting heads offer better results.
- Devices with icepoint systems are more comfortable and less painful. Sapphire tips are the best.
- Larger light-emitting areas speed up hair removal.
- More flashes mean longer device life.
- More adjustable settings increase comfort.
- Quartz lamp materials have a longer lifespan.
- Detachable designs are lighter and easier to operate.
05 Pain Levels for Hair Removal in Different Areas
Key Points: Treatment may cause a burning sensation, similar to a mosquito bite. Pain is more noticeable in sensitive areas like the bikini line and face. First-time sessions, darker skin, and thicker hair increase pain.
- Most Painful Areas: Bikini area and face, as they have higher densities of pain receptors.
- Factors Affecting Pain:
- Number of sessions: Initial sessions are the most painful.
- Device choice: Devices with cooling systems reduce pain.
- Individual factors: Darker skin and thicker hair increase pain due to higher light absorption.
06 Side Effects of Hair Removal
Key Points: High temperatures from light-based treatments may cause burns or accelerate skin dehydration, leading to redness, itching, or dryness. These usually resolve in 3–7 days.
07 Can Underarm Hair Removal Cream Cause Body Odor?
Generally, hair removal creams do not cause body odor. Body odor, or bromhidrosis, is caused by excessive sweat secretion from underarm apocrine glands, which is broken down by bacteria into foul-smelling substances. It is genetic and common in young adults.
However, frequent use of hair removal creams with harsh chemicals may irritate the skin, increase sweating, and lead to odor or redness. Limit use to once a week. Consult a doctor for specific concerns.
08 Will Shaving Facial, Underarm, or Toe Hair Make It Thicker?
Key Point: Hair thickness and quantity are determined by genetics.
In adulthood, hair thickness and quantity remain relatively constant. Shaving does not make hair thicker or more abundant. Therefore, you can safely shave facial, underarm, leg, or toe hair.
Why Does Hair Feel Thicker After Shaving?
Newly grown hair is short, making the stubble appear darker and coarser. Once fully grown, it no longer looks as thick.
09 What Should You Avoid After Laser Hair Removal?
Key Points: Post-treatment skin may itch, usually subsiding within a day or two. Maintain moisturization and sun protection for better recovery. Redness or swelling may occur but typically resolves in 1–3 days.
- Immediately After Treatment:
Apply ice packs if there is redness, swelling, or pain. Otherwise, no special care is needed. - Day 1 Post-Treatment:
Avoid hot water on treated areas.
Do not use刺激性 skincare products. - Days 2–14 Post-Treatment:
Avoid sun exposure and apply body lotion.
Do not use other hair removal products.
