At a glance
IPL (Intense Pulsed Light) therapy is a non-surgical skin treatment that uses broad-spectrum flashes of light to target and reduce a range of visible skin concerns, from sunspots to broken blood vessels.
The device releases multiple wavelengths of light at once, unlike a laser which uses only one. This light is absorbed by pigment (colour) in the skin or by the red colour in blood vessels, converting to heat. That heat breaks down the targeted cells without cutting the skin. The body then clears away the debris naturally over the following weeks, leaving clearer, more even-toned skin behind.
Medical Condition
Dermatologists use IPL to address skin changes caused by sun exposure, aging, or certain chronic skin conditions. It works best on people with lighter skin tones where the contrast between the target and the surrounding skin is clear enough for the light to work selectively.
- Sunspots and age spots (flat brown patches caused by UV exposure)
- Rosacea (a condition that causes persistent facial redness and visible small blood vessels)
- Broken capillaries (tiny visible blood vessels, often on the nose and cheeks)
- Freckles and uneven skin tone
- Mild to moderate acne and the red marks acne leaves behind
- Poikiloderma (a sun-related skin change combining redness, brown patches, and thinning of the skin, often on the neck and chest)
- Fine lines and mild skin laxity (looseness)
- Unwanted hair on the face and body (hair removal IPL)
IPL is not suitable for everyone. A dermatologist will assess skin type carefully before recommending treatment.
- Darker skin tones (Fitzpatrick skin types V and VI), because the light may target skin pigment rather than the intended concern, raising the risk of burns or pale patches
- Active tan from the sun or a tanning bed, for the same reason
- Active skin infections, open wounds, or inflammatory skin conditions in the treatment area
- Pregnancy
- Certain photosensitising (light-sensitising) medications, including some antibiotics and acne treatments
- A history of keloid (raised, overgrown scar) formation
- Epilepsy triggered by flashing lights
Risks & Complications
IPL is generally considered a low-risk procedure when performed by a trained clinician on a suitable skin type, but side effects do occur and patients should be aware of them before proceeding.
- Temporary redness and swelling in the treated area, usually settling within a day or two
- A feeling of warmth or mild stinging during and just after the session
- Darkening of treated spots before they flake off, which is a normal part of the process but can be alarming
- Blistering or crusting, more likely if the device settings are too high or the skin has been recently sun-exposed
- Temporary hyperpigmentation (darkening of the skin) or hypopigmentation (lightening of the skin), particularly in darker skin tones
- Paradoxical darkening, where pigmented lesions initially become more prominent
- Rarely, scarring if blistering is severe or the treated area becomes infected
- Eye injury if protective eyewear is not worn during the session
Preparation & Procedure
In the weeks before IPL, protecting the skin from sun exposure is the most critical step. Most clinicians ask patients to avoid deliberate tanning, including tanning beds, for at least four weeks beforehand, and to use a broad-spectrum sunscreen daily.
Several products and medications need to be paused before treatment. Your dermatologist will give specific guidance, but common items include photosensitising medications (such as certain antibiotics and some acne treatments), retinoids (vitamin-A skin products), and chemical exfoliants. Alcohol-based and perfumed skincare is usually stopped a few days before. Self-tanning products should not be used in the weeks leading up to the appointment.
Unlike surgical procedures, IPL does not require fasting. The treatment area should be clean and free of makeup, moisturiser, and sunscreen on the day of the appointment.
Before the first session, the dermatologist will usually carry out a skin assessment that may include:
- A detailed review of medical history, current medications, and any history of cold sores in the treatment area
- Assessing skin type using the Fitzpatrick scale (a classification of skin colour and its response to UV light)
- A test patch, where a small area is treated first and reviewed at a follow-up visit to check for adverse reactions
What typically happens during the session itself:
- 1. The patient and clinician both put on protective goggles to shield the eyes from the light flashes.
- 2. A cool gel is applied to the skin to help the device glide smoothly and to reduce discomfort.
- 3. The handheld IPL device is pressed against the skin and delivers a series of light flashes across the treatment area.
- 4. Patients usually feel a sensation described as a rubber band snapping against the skin.
- 5. A single session on the face typically takes between fifteen and forty-five minutes, depending on the area being treated.
- 6. The gel is wiped away and a soothing moisturiser and sunscreen are applied.
Aftercare
Most patients leave the clinic immediately after their session with no need for a recovery room. The skin will look flushed and feel warm, similar to mild sunburn, for a few hours to a day. Treated spots may darken and form a light crust before naturally shedding over the following one to two weeks. This is expected, not a complication.
- Apply a gentle, fragrance-free moisturiser and a high-SPF sunscreen every day, starting immediately after the session. Sun protection is the single most important thing during recovery because treated skin is more vulnerable to UV damage.
- Avoid direct sun exposure, especially during peak hours, for at least two to four weeks after each session.
- Do not pick, rub, or scratch darkened spots or crusts, as this raises the risk of scarring.
- Skip heat-generating activities such as saunas, steam rooms, and intense exercise for two to three days after treatment.
- Avoid retinoids, chemical exfoliants, and alcohol-based products until the skin has fully settled, usually around one week.
- Cool compresses can help relieve redness and warmth in the first day or two.
- Multiple sessions are almost always needed for noticeable results. Most treatment plans involve between three and six sessions spaced several weeks apart, though the exact number depends on the condition being treated and how the skin responds.
- Follow-up appointments allow the dermatologist to assess progress, adjust device settings if needed, and decide whether further sessions are beneficial.
- Long-term maintenance sessions may be recommended once or twice a year to sustain the results, particularly for conditions like rosacea or recurrent sun damage.
Cost & What Determines It
The cost of IPL therapy varies widely depending on where and how it is performed. A single session for a small area is priced very differently from a multi-session course covering the full face, neck, and chest, and the country and type of facility chosen add further variation.
- Area and extent of treatment: a small targeted patch costs less than a full-face or body session.
- Number of sessions: most clinicians recommend a course of several sessions rather than one, and packages may be priced differently from individual sessions.
- Skin condition complexity: severe or widespread pigmentation, rosacea, or vascular concerns may require more sessions or higher device settings.
- Type of IPL device: newer or more precisely calibrated machines tend to be priced higher.
- Hospital or clinic class: a university hospital dermatology department, a private specialist skin clinic, and a medical spa occupy very different price points.
- Country of treatment: labour costs, import costs for equipment, and facility overhead differ significantly across countries.
- Clinician seniority: a session performed by a board-certified dermatologist is usually priced above one delivered by a supervised technician.
- Add-on treatments: IPL is sometimes combined with other procedures such as topical treatments or a chemical peel in the same visit, which affects the total cost.
- Consultation fees: an initial assessment and any test-patch appointment may or may not be included in a quoted package price.
Clinic packages abroad often bundle a set number of sessions, the consultation, consumables (gel, soothing products applied after treatment), and a follow-up check. Items that tend to be billed separately include prescribed skincare products for home use, additional sessions beyond the original course, and any treatment of unexpected complications.
BPJS Kesehatan does not cover aesthetic procedures, and most Indonesian private health insurance policies also exclude them. Patients who choose IPL abroad typically pay out of pocket, although holders of international private insurance should check their policy documents carefully, as coverage for medically indicated uses of IPL (such as treating a recognised skin condition) sometimes differs from purely cosmetic use. Before travelling, ask the clinic for a written itemised estimate that clearly states what is and is not included so there are no unexpected charges on arrival.
Frequently Asked Questions
How many IPL sessions will I need?
Most people need between 3 and 6 sessions to see a noticeable result, spaced roughly 3 to 4 weeks apart. The exact number depends on what you are treating, such as sun spots, redness, or unwanted hair, and how your skin responds after the first couple of sessions. Your dermatologist will reassess the plan as you go.
What does IPL therapy feel like, and does it hurt?
Most patients describe each pulse of light as a quick snap or mild sting, similar to a rubber band flicking against the skin. The feeling fades within seconds, and many devices come with a built-in cooling feature that reduces discomfort. Sensitive areas of the face may feel sharper, but the session itself is generally well-tolerated.
How soon will I see results from IPL, and what should I avoid during treatment?
Some changes, like darkened spots rising to the skin surface before flaking off, can appear within a week of the first session, but the fuller result usually builds over several weeks as the skin renews itself. During your course of treatment, doctors typically advise staying out of direct sun, avoiding tanning beds, and skipping products that irritate the skin, such as retinoids (vitamin A creams) and chemical exfoliants. Protecting your skin from sun exposure between sessions helps the treatment work as intended.
How much does IPL therapy cost?
The cost of IPL therapy varies depending on the number of sessions recommended, the size of the area being treated, and the class of clinic or hospital you choose. Treating a small focused area costs differently from a full-face course, and some clinics include post-treatment skincare in the package while others price it separately. Requesting a written estimate from the hospital before you commit gives you a clear and accurate figure for your situation.
