In today’s article, we’ll discuss IPL hair removal with the New Ulike Air3 hair removal device. IPL hair removal method is safe, faster, cost-effective, and more convenient compared to other hair removal methods. Most dermatologists (* Ulike entered into a commercial arrangement with 2-3 dermatologists, which provided positive reviews) do recommend the IPL hair removal technique because its results are long-lasting. If you want your unwanted hair to stop regrowing using this method, treat the skin 4-6 times at least twice per week.

IPL hair removal works by heating up the hair follicle until it’s damaged. Once damaged, hair regrowth is retarded and the little that regrows is thin and weak.

To achieve the best IPL results, observe a strict treatment plan and shave the area to be treated 12-24 hours before treatment. As a precaution, consider the thickness of your hair when selecting the IPL hair removal device to use.

What is IPL?

IPL stands for intense pulse light . It’s a type of light treatment that uses intense pulses of light to stimulate or produce heat within tissues and within the skin. When the light is absorbed by the melanin in the hair follicles, it turns into heat destroying the hair follicles and setting the hair root dormant.

Hair follicles surround the hair root and hair strand. It’s the hair follicles that are responsible for hair growth.

Basic science and clinical heavens have been published to confirm the efficacy and the technical safety of the many laser and home-use IPL devices for hair removal. Similar to lasers, the basic principle of IPL devices is more or less selective further than the lasers – in other words, selective damage of the tap tissue.

IPL is a safe and very effective treatment for at-home hair removal. When looking for an IPL at-home hair removal device, ensure it’s FDA-cleared, and SGA-tested like the IPL devices from Ulike .

The New Ulike Air3 has over 30 international safety certifications and is FDA-cleared. Not only is it Safe, but it’s also suitable for sensitive skin and ideal for the whole body including the face and bikini area.

Does the Air3 really hurt? The cooling tip feels quite nursing to the skin. This is because it’s nearly painless and it doesn’t mean it’s ineffective.

How Ulike Air3 Cooling System Works And How It Improves Efficacy.

Light absorption by melanin causes epidermal damage. That is, it damages the uppermost layer of the skin. This minimizes the maximum fluence or energy in the IPL hair treatment procedure . The cooling effect protects the uppermost layer which is called the epidermis. And this permits higher energy levels to be emitted to the skin. The cooling is done with state-of-the-art Sapphire Crystal Technology.

The Ulike Sapphire Air3 and the Air+ Sapphire Crystal large window are in full contact with the treatment area. This provides the much-needed cooling effect throughout the hair removal treatment process. This technology protects your upper layer of the skin and ensures a comfortable user experience when performing effective hair removal.

Science Behind IPL Hair Removal

With all forms of energy hair removal devices, we would like to heat up the hair root and stem cells which lie in a particular area and a particular depth of the hair follicle itself. Whether using the IPL or the laser, a contrast in pigment is essential. For example, hair that is darker than the surrounding skin.

The IPL device delivers light that uses light in a broad spectrum. Light produces heat which is transferred from the stem of your hair follicle to the hair bulbs where the stem cells live. When this happens, the heat destroys the germ cells and the hair is long-lasting reduced.

Not all hair follicles are in the hair-growing phase. In fact, only 20 percent is in the growth stage and hence the requirement to use IPL hair removal devices at regular intervals. To get the best results, dermatologists recommend using IPL for months rather than weeks.

Difference Between Ulike Air+ and Ulike Air3

Given the choice to choose between the Ulike Air + and the Ulike Air3, you might be surprised what really is the difference. Besides the new look in the Ulike Air3 , it now has an auto glide feature. With the new auto glide window, you can now glide across the skin and the light will automatically flash.

So, if you’re looking for an IPL device that will save you time when treating large body areas like the legs, arms, and stomach, Ulike Air3 is the device to use. This means you can treat your whole body for about 10 minutes. Comparatively, you’ll take less time compared to salon hair treatment which often takes 45 minutes to one hour.

You only need to use Air3 three times a week for the first 4 weeks, then 2 times a week for 2 months. Next, you’ll just need a top-up once every three months. Within the first three weeks, you should be able to see results such as smooth skin, and a noticeable hair reduction after only 4-5 times of treatment (* refers to a decrease in hair count within 3 weeks, sourced from third-party laboratory testing reports. Individual results may vary).

Other Ways of At-Home Hair Removal

Besides IPL, there are many other hair removal methods. To treat your skin for long-lasting hair removal, you have laser and IPL hair removal methods. In most cases, the laser technique is done at a salon or in a dermatologist’s clinic.

The major hair removal methods include shaving, IPL hair removal, waxing, laser hair removal, electrolysis, depilatory cream, and epilation. The common drawback in epilation, laser, and electrolysis hair removal methods is the painful experience. Depilatory creams, waxing, and shaving though still used by many, these methods aren’t long-lasting.

1. Shaving

Shaving as an at-home hair removal technique has been used for ages by both men and women of all ages. Although not painful and cheap, hair regrows fast within a short period. Anyone can shave him/herself and it takes a short time to do the shaving.

And while other options like laser are limited to the body areas you can remove hair, shaving takes care of every part of the body. The risks associated with shaving are cuts, irritation, razor burns, and nicks. Ingrown hair is the major disadvantage of using the shaving hair removal method.

2. Waxing

Waxing hair removal was adopted largely in the 1960s and is today used by many worldwide. The different ways you can use to wax the hair on your legs, arms, underarms, stomach, and face are strip waxing, hard waxing, sugar waxing, and fruit and chocolate waxing.

Pulling out the hair with wax is painful. For a less painful experience, trim the hair to about ½ – ¼ inch. With proper waxing, it takes 3-4 weeks for the hair to regrow.

3. Laser Hair Removal

With laser hair removal devices available for home use, you can now long-lasting remove any unwanted hair from your body. Since laser light energy is strong, it’ll take you at least 6 months to remove unwanted hair long-lasting.

Due to the strong beam of light used to destroy the hair follicle, one is likely to experience minimal pain or incur burns if the laser device is used by an inexperienced person.

4. Epilation

Epilation is a cheap and easy hair removal technique anyone can use at home. Epilation devices are available everywhere, cheap to buy, and simple to use. This method entails using an epilator to pull out the unwanted hair from the body.

Epilation is among the most painful hair removal technique. However, as one continues to epilate, the painfulness decreases.
