Start shedding in winter, it’s just right in summer! Delicate “furry kids”, come in!

It is said that hair loss makes people sad, but excessive hair is also annoying. Everyone loves beauty, and fair and smooth skin is probably the dream of every "kiwi girl". On the road to realizing the dream, razors, wax, and depilatory creams have become good friends of beauty-loving girls, and of course there is also the strongest helper: a hair removal device!

When it comes to hair removal devices, everyone has heard of them to some extent. If you happen to know only a little about it and are full of questions, let’s learn about it together!

Question 1

Q: What are some reliable hair removal methods?

Answer: Common hair removal methods include razor, depilatory cream, wax, laser... They are suitable for different people and parts in different situations.

Shaving: Using a razor to remove hair is the quickest method, but it needs to be repeated frequently as the hair will grow back within a few days.

Depilatory creams: These use chemicals to dissolve hair, making it easier to wipe off. They usually last longer than razors, but they also need to be used regularly.

Waxing: Cover the hair with wax and tear it off quickly after it solidifies, thus removing the hair by the roots. It can keep the skin smooth for a long time, but it hurts!

Laser hair removal: This is a medical cosmetic procedure that uses a laser beam to damage hair follicles to slow hair growth. It usually requires multiple treatments and has long-lasting effects, but is more expensive.

Electronic hair removal: It is also a medical cosmetic method, usually performed by professionals, which uses electric current to pass through fine needles to destroy hair. The effect is long-lasting, but multiple treatments are required.

Question 2

Q: What is the principle of the hair removal device?

A: The principle of hair removal device may vary depending on different types of hair removal devices.

The handheld part of the hair removal device usually includes a probe, a light source, a lens system, a power control and an operation panel, and the user can set parameters such as light intensity and light flashing frequency.

Generally speaking, the most common hair removal devices we use are intense pulsed light (IPL) and laser hair removal devices.

Intense pulsed light hair removal device uses a broad spectrum light beam to convert light energy into heat energy by emitting multiple intense pulsed light wavelengths to damage hair follicles and slow down hair growth.

Laser hair removal devices use a single wavelength laser beam to precisely target energy at the hair follicles, destroying their ability to grow.

Some other hair removal devices may use different principles, such as electronic hair removal, radio frequency hair removal, microwave hair removal, etc. Basically, electrical energy is delivered to the hair follicles to destroy hair growth.

The sapphire hair removal device we often hear about is an IPL or laser hair removal device. Its name usually comes from the use of sapphire as part of the optical lens or window to help focus and guide the light beam. This hair removal device is famous for its efficient and long-lasting hair removal effect.

The Sapphire Hair Removal Device works similarly to other IPL or laser hair removal devices. It emits intense pulsed beams of light that are absorbed and converted into heat, which is then targeted at the hair follicles, disrupting their ability to grow. The use of a sapphire lens helps ensure precise focusing and positioning of the beam to reduce unnecessary damage to the surrounding skin. Sapphire Hair Removal Devices are generally suitable for a variety of different skin types and hair colors, but the results are generally more significant for darker hair.

When choosing a hair removal device, it is best to choose the appropriate type and brand according to your needs, skin type and budget to get the best hair removal experience.

Of course, no matter what type of hair removal device you use, you need to study the instructions carefully to ensure that you can operate the device safely and effectively.

Question 3

Q: Are there any health risks with home hair removal devices?

A: Home hair removal devices are generally relatively safe when used correctly, but there are still potential risks.

Home hair removal devices typically use pulsed light or laser technology to slow or reduce hair growth and are relatively safe when used correctly, but there are still some potential risks.

For example, people with different skin types react differently to hair removal devices. Some people may temporarily feel heat, pain, tingling or itching on their skin after laser irradiation. These discomforts are usually short-lived, but may last for a few days after treatment.

If the laser hair removal device is not set up correctly, or is not operated correctly, it may cause skin burns, which usually appear as redness, blisters, bruises or pain. It is very important to set the laser energy and pulse width correctly, and operate the device correctly, so as to reduce the risk of burns.

Some people may develop skin pigmentation or spots after laser hair removal, especially on skin exposed to the sun. This may be caused by not adequately protecting the skin from UV damage. It is critical to do a good job of sun protection.

In some cases, laser hair removal may stimulate hair follicles, causing thicker or coarser hair to grow. This is usually temporary and does not cause permanent changes.

Although laser hair removal devices are generally safe, there is still some risk of infection, especially if the skin is not properly cleaned.

Question 4

Q: Is a home hair removal device a waste of money? How is it different from the hair removal devices used in beauty salons?

Answer: Home hair removal devices are not necessarily a waste of money, but for some people, they may not be the most economical choice.

Cost

Home laser hair removal devices are usually portable and small, requiring an initial investment and periodic maintenance or replacement of parts. If used infrequently, the total cost of a home laser hair removal device may be higher than going to a beauty salon for hair removal.

Commercial laser hair removal equipment generally refers to professional medical beauty equipment, which is usually large in size, requires fixed installation, and is expensive. Home use equipment is much more affordable.

Operational safety

Commercial devices typically have adjustable pulse widths and wavelengths that can be adjusted to suit different hair types and skin types, and are operated by professionally trained medical aestheticians or technicians who can personalize treatments based on the patient's needs and skin type, which helps ensure safety and effectiveness.

Home devices usually have fixed settings and are not as flexible and precise as commercial devices. They require users to operate them themselves, which may involve potential risks.

Hair removal effect

Commercial laser hair removal devices typically have higher power and energy density, can target hair follicles more deeply, and require fewer treatments to achieve long-term hair removal results, while home devices may require more frequent treatments to achieve similar results.

In general, commercial laser hair removal devices are more powerful and precise, and are usually operated by professionally trained personnel to provide better results and greater safety. Home laser hair removal devices are more suitable for those who want to remove hair at home, but they need to follow the instructions for use of the device carefully. Which device to choose depends on personal needs, budget, and safety awareness.

Question 5

Q: What are the precautions for hair removal?

A: Learn about the instructions for using the hair removal device, skin testing, sun protection, cleaning...

Understand the product: Before hair removal, you need to carefully read and follow the instructions for use of the hair removal product or device and use it in the correct way. It is best to do a small area skin test first to ensure that there is no allergic reaction or discomfort.

Skin sun protection: Hair-removed skin may be more susceptible to sun damage, so use inorganic sunscreen to protect your skin, or you can choose to remove hair in autumn and winter.

Skin type: Different skin types react differently to hair removal methods. For example, sensitive skin may be more prone to redness or stinging, while coarser hair may require more care. Knowing your skin type can help you choose the right hair removal method for you.

Hair color: The effectiveness of hair removal methods is often related to hair color. Light therapies (such as laser hair removal) usually work better on dark hair, while electronic hair removal is less effective on light hair. Hair removal creams and razors are generally not sensitive to hair color.

Area Selection: Skin sensitivity and thickness vary in different areas. For example, the face, underarms, and bikini line areas are usually more sensitive than the legs and require a more gentle or professional approach.

Protect your eyes: Hair removal devices should not usually be used on the face or around the eyes because the laser or strong light may damage the eyes. When using a hair removal device, remember to wear protective sunglasses.

Hair removal cycle: Using a hair removal device usually requires multiple treatments to achieve long-term hair removal results, as hair is usually in different growth stages. The hair removal cycle may vary depending on individual circumstances and usually requires several months of treatment. Of course, do not overuse hair removal products or devices to avoid damaging the skin.

Prevent infection: Before performing any form of hair removal, make sure the skin is clean and use sterile tools and cleaning products to reduce the risk of infection.

In short, hair removal is a personal care process. You should be careful and choose the right method according to your needs, skin type and regional characteristics. Of course, if you have special skin conditions or concerns, it is best to perform hair removal under the guidance of a professional.
