IPL Machine Functions by Each Filter

IPL machine usually equipped with sever filters. The filters usually varies from 400nm – 1200nm.

The commonly seen filters are: 420nm-1200nm, 480nm -1200nm, 530nm -1200nm, 590nm-1200nm, 640nm -1200nm, 690nm- 1200nm, 750nm -1200nm etc..

Below are the 5 filters we offer for all our IPL machines, and their functions:

1). 480nm~1200nm: Acne treatment

2). 530nm~1200nm: Vascular treatment, photofacial for light skin.

3). 590nm~1200nm: Pigmentation treatment, photofacial for dark skin.

4). 640nm~1200nm: Hair removal for light skin

5). 690nm~1200nm: Hair removal for dark skin

Why we choose these filters and why these filters has these functions? We have explain from the wavelength. Please see below picture:

600-1200nm has a deep penetration depth into the skin, which is called the first treatment window. 400-600nm has a medium penetration depth into the skin.

From 400-1200nm, the penetration depth of light to the skin is basically proportional to the wavelength.

Why choose IPL 480nm -1200nm filter for acne treatment?

Ultraviolet light less than 400nm has sterilization effect. We use 480nm -1200nm for acne treatment. You may wonder, since ultraviolet has better effect in sterilization, then why we don’t directly use ultraviolet wavelength to do the acne treatment therapy? That is because, 380-230nm ultraviolet rays have the effect of accelerating skin aging and carcinogenicity. So we must avoid this spectrum.

The lower limit of the wavelength is selected at ≥380nm. Because 380-400nm is used for ultraviolet sterilization, there may be lead to a period of “ultraviolet erythema”.

As you may noticed, in the market there are other factories using 420nm-1200nm filter for acne. So why we do not use 420nm filter but use 480nm filter for acne? That is because the short wavelength that under 480nm has a tanning effect.

Why choose IPL 530nm -1200nm filter for vascular therapy?

Many reasons may cause the broken capillaries. But once facial veins appear, they can’t be repaired. The only way to reduce their appearance is to remove them with professional facial vein treatment, such as the IPL vascular treatment. But why and how IPL 530nm remove the facial veins?

The absorption peaks of hemoglobin are 415 nm, 540 nm, and 580 nm.

Since the short wavelength of <480nm has a tanning effect, it should be avoided in the treatment of vascular diseases. It is best to choose near the two peaks of 540-580nm, and the lower limit should be close to 540nm rather than 580nm. Therefore, most of the treatment of vascular diseases is the lower limit of wavelength between 500-600nm. We choose 530nm as the lower limit value for the vascular therapy which has been proved has very good effect.

Why choose IPL 590nm -1200nm filter for pigmentation treatment?

Also in order to avoid the side effects of <480nm, and considering that melanin is only distributed in the epidermis, shallow penetration is required. [caption id="attachment_1708" align="alignnone" width="750"] IPL machine effect in pigmentation treatment[/caption]

Therefore, using 590nm wavelength can effectively remove melanin. At the same time, it can also remove wrinkles and rejuvenate the skin, as well as remove the pigmentation.

Why choose IPL 640nm / 690nm -1200nm filter to do hair removal treatment?

The root of the hair is 3-5mm under the epidermis, so hair removal requires a wavelength that penetrates deeper into the soft tissue.

At the same time, due to the large size of the hair follicle to be destroyed, its diameter is 30-100 nm, and a long wavelength with high photothermal conversion efficiency is also required. On the other hand, if the wavelength is too short, the melanin in the epidermis will absorb the most of energy first before it entering to the hair follicle.Such heat will be generated in the epidermis, which may cause epidermal burn. So the lower limit value of hair removal treatment shall be 640nm. If client skin doesn’t has much melanin (skin tone is fair), 640nm filter is ok. If client skin has melanin, or client skin tone is darker, we suggest to choose 690nm filter.

It is never too late to buy an IPL machine for your salon. You can get back all the investiment after just 3 clients!
