What Is an IPL Photofacial? How Intense Pulsed Light Works

The term “photofacial” can make IPL sound like a facial treatment similar to cleansing or exfoliation. It is not. IPL is an energy-based procedure that uses controlled flashes of light to target color in the skin, especially melanin in brown spots and hemoglobin in visible vessels.

How Does IPL Work?

IPL devices produce pulses of broad-spectrum light. Filters and treatment settings are chosen so that more of that energy is absorbed by the intended target in the skin. The absorbed light is converted into heat, which can injure unwanted pigment or small vessels while trying to limit unnecessary injury to surrounding tissue.

For brown spots, treated pigment may temporarily darken before gradually flaking or fading. For redness and visible vessels, controlled heating can cause selected vessels to shrink or become less visible over time.

What Does an IPL Photofacial Treat?

IPL is most established for pigment and vascular concerns related to photodamage. Research also supports its use for facial erythema and telangiectasia associated with rosacea, although treatment plans vary substantially between devices and studies.

What IPL Does Not Do

IPL is useful, but it is often oversold. It does not “erase” every form of pigmentation, permanently remove pores, or replace resurfacing for deep wrinkles and scars. It also should not be treated as a guaranteed one-session procedure.

IPL can be used in some acne protocols, but a standard photofacial is not primarily an acne treatment. Active acne, post-acne redness, brown post-inflammatory pigment and true acne scars are different problems and may require different treatments.

IPL Photofacial vs. Laser Treatment

IPL and lasers both use light energy, but they deliver it differently. IPL covers a broader range of wavelengths and can target more than one type of visible discoloration in the same treatment plan. A laser can be more wavelength-specific and may be preferred when the target requires greater precision or when deeper resurfacing is needed.

For example, Pico laser may be considered for selected pigment concerns where a picosecond laser approach is appropriate, while laser resurfacing is generally more relevant when texture, wrinkles or scars are the dominant issue.

What Does an IPL Treatment Feel Like?

Most people describe brief warmth or a snapping sensation as individual pulses are delivered. Cooling systems or gel may be used depending on the platform. Treatment comfort varies by area, settings and individual sensitivity, so describing IPL as completely painless is not accurate.

Immediately afterward, temporary redness or mild swelling can occur. Brown spots often become darker before they fade or flake. The exact recovery pattern depends on the settings and what was treated.

How Many IPL Sessions Are Usually Needed?

Photorejuvenation is commonly performed as a series rather than a single treatment. A systematic review of IPL skin-rejuvenation studies included 637 participants and reported a mean of about four treatments across the included studies. The ideal number still varies by concern, skin response and device settings.

Skin Works currently describes a typical IPL plan as approximately three to five sessions spaced several weeks apart. If you are considering treatment, the IPL Photofacial service page has the current treatment plan, areas and pricing rather than duplicating those commercial details here.

Is IPL Safe for Darker Skin Tones?

IPL requires additional caution in darker skin because melanin in the epidermis can also absorb light energy. That creates a greater risk of unwanted heating, burns and post-inflammatory hyperpigmentation if the wavelength range, fluence, pulse structure or cooling are not appropriate.

This does not mean every person with darker skin is automatically excluded. It means skin type, recent tanning, the specific diagnosis and the device settings matter more. Published evidence on photorejuvenation has historically included mostly Fitzpatrick I through IV, so claims of identical safety across every skin tone should be avoided.

What About Melasma?

Melasma is more complicated than a simple sun spot. Light and laser treatments can sometimes improve it, but recurrence and pigment worsening are possible. A 2025 review of laser and light therapies for melasma emphasized that the condition is chronic and challenging, with treatment choice depending heavily on patient and pigment characteristics.

If facial pigment may be melasma rather than isolated sun damage, the first step should be identifying the pigment pattern correctly rather than assuming IPL is the right treatment.

What Are the Risks of IPL?

Potential side effects include redness, swelling, temporary darkening of pigment, crusting, blistering, burns, post-inflammatory hyperpigmentation and hypopigmentation. Eye protection is required during treatment because intense light can injure ocular structures.

Risk is influenced by skin type, recent sun exposure, tanning, photosensitizing medications, the condition being treated and device settings. This is why a real skin assessment matters before treatment.

How IPL Fits With Other Skin Treatments

IPL is strongest when the treatment goal is broad superficial pigment and vascular redness. It is not automatically the best choice for every skin concern.
