It is said that 85% of girls have problems with body hair! How can you have armpit hair when you are wearing a tank top and raising your hands! How can you spend the summer wearing fur? There are also various hair removal products on the market. So, what is the difference between a hair removal device and a hair removal cream?

The difference between hair removal device and hair removal cream

1. Hair removal cream

The principle ingredient of depilatory cream is a chemical substance that irritates the skin. The principle of hair removal is to break the hair from the root, thereby achieving the effect of hair removal, but the hair roots will remain in the hair follicles, so they will be thicker and darker when they grow next time. . Depilatory creams use chemicals that dissolve the hair structure to achieve the purpose of hair removal. The main ingredient of this preparation is calcium hydrochloride. Its usage is relatively simple. Clean the skin before use to reduce irritation. Apply the depilatory cream evenly on the area to be depilated. After 5-10 minutes, the hair becomes soft and can be scraped off with a scraper.

2. Hair removal device

The hair removal device uses the principle of laser hair removal. Laser hair removal works by emitting light of a specific wavelength to act on the hairy parts of the skin. The laser will penetrate into the hair follicle structure in the skin layer and cause the hair follicle to shrink under the action of heat energy, losing the ability to regenerate and stop the production of melanin, thereby achieving the effect of permanent hair removal. You can refer to the techniques in "Mao Xin Nao Hu" to learn more about the tricks to quickly and permanently remove sweat hair. The principle of laser hair removal is to use the characteristics of laser (selective photothermal therapy) to be absorbed by the melanocytes of hair shafts and hair follicles, thereby destroying the hair follicles without harming other normal surrounding tissues. The hair growth cycle can be divided into three phases: growth phase, transition phase, and resting phase. When hair is in the growth phase, its follicles are fully developed and contain melanin, which determines the hair's color. At this time, if long-pulse laser irradiation is used, melanin can be destroyed, achieving the purpose of hair removal due to hair follicle atrophy.

Pros and cons of hair removal cream

The advantage of hair removal cream is that it is convenient and relatively cheap. However, the effect is short-lived and harmful to the human body. Depilatory cream is a chemical agent and is quite irritating to the skin. In addition, depilatory cream stays on the skin for a long time. If your skin is prone to allergies, or you buy a bad brand, or you use it excessively, it can easily cause redness, swelling and allergies.

Advantages and disadvantages of hair removal devices

Compared with depilatory creams, hair removal devices are relatively safe and do not contain any chemical ingredients that can directly harm the skin. The effect period it maintains is also relatively long. However, hair removal devices are not perfect because they are only suitable for people with light skin but dark hair. If you have dark skin, the laser will destroy your skin pigment and cause white spots or dark spots.

Can a hair removal device remove hair permanently?

Whether a hair removal device can permanently remove hair depends on personal physical condition. For most people, laser hair removal requires multiple treatments over a 2 to 3 month period. After using an epilator, the hair will likely grow back. If during laser hair removal, the hair follicles are damaged but not completely destroyed, there is a high chance that the hair will regrow. If the heat from the laser destroys the hair follicles, the hair will not grow again. When the hair follicles are necrotic, laser hair removal is permanent. If the hair follicles are only damaged, the hair will grow again. How long it takes for hair to grow back depends on each person's unique hair growth cycle. Some people's hair grows faster than others. Hair in the dormant phase grows more slowly than hair in other phases.
