All About IPL (Intense Pulsed Light)

You may have seen “IPL” pop up on clinic menus, or overheard your friends mentioning it in relation to skin brightening or hair removal. It’s one of those treatments that seems high-tech but has actually become extremely common in recent years.f

We’re going to break that down in an easy, human way so you understand exactly what it is, what it can do and, maybe most important, what you can expect.

What Is IPL Anyway?

IPL stands for Intense Pulse Light. It’s not a real laser (although lots of people call it that). Unlike lasers, which fire a single wavelength of light at the skin, IPL releases a large spectrum of light that can strike all at once.

The device uses a handpiece with a glass window that rests against your skin. When it fires, it delivers short flashes of light in various wavelengths (typically 500 nm to 1200 nm).

Because it uses a broad spectrum rather than one single beam, it can tackle multiple skin concerns—like redness and brown spots—at the exact same time.

How Does IPL Actually Work?

Here’s the easy version:

• The light goes through your skin.
• The targets in the skin are specific for different colours – such as haemoglobin (which is red in blood vessels), melanin (which is brown pigment that lives in hair or spots) or water.
• The light is absorbed and converted to heat.
• That heat kills or burns away the intended target (the hair follicle, pigment spot or tiny blood vessel) without burning surrounding skin too much.

Often IPL machines include a cooling system in the form of chilled glass or gel, to make the surface cool and also protect the surface of the skin.

What Can IPL Treat?

IPL is sort of a multitool for the skin. Here are some of the most common applications:

1. Hair Removal: IPL is a popular choice for the face, underarms, and legs. While it’s great for light to medium skin tones, it isn’t a ‘one size fits all.’ Results depend on the contrast between your hair and skin. It’s most effective when the hair is dark and the skin is light. You’ll generally need 6–8 sessions to see a significant drop in growth.
2. Sun Damage & Pigmentation: Brown spots, freckles, age spots and uneven skin colour fade away very well. IPL shatters additional melanin, and your body then eliminates it.
3. Redness & Broken Capillaries: Small red veins on the face, nose or décolletage (often due to rosacea or sun damage) will be zapped and diminish over a few treatments.
4. Rosacea & Facial Flushing: Helps reduce frequency of flushing and reduces redness and visible blood vessels, making skin look calm + even.
5. Acne: Some IPL devices include specific filters that are designed to kill acne-causing bacteria and minimize oil production. It’s not a miracle worker, but really helps with active breakouts and any red marks left behind.
6. Skin Rejuvenation (Photo Facial): Also known as “IPL photofacial” or “photo rejuvenation. It helps with collagen, tightens pores, smoothes texture and gives you a brighter, more youthful glow.

 

Who Is IPL Good For?

IPL works best on:

• Light to medium/light skin (Fitzpatrick I–III)
• Dark hair for hair removal
• Those with sun or age-related damage, redness and uneven tone

It’s not great for very dark skin tones (Fitzpatrick IV–VI) because the melanin in the skin absorbs too much light, leading to burns or dark patches. For skin of darker skin tones, ND:YAG lasers are typically safer.

 

What does it feel like to have an IPL treatment?

Most people describe the sensation as a warm ‘snap’ or a mild flick of a rubber band. The built-in cooling systems or chilled gel used during the session make it much more comfortable.

A face treatment usually takes about 15-20 minutes, while larger areas like the legs take a bit longer. Your skin might look slightly pink for a few hours—almost like a mild sunburn—but you can usually pop your makeup back on the very next day.

How Many Treatments Do You Need?

While that post-treatment glow shows up pretty quickly, achieving long-term change takes a bit of patience. Because IPL works in cycles, you won’t get the full effect in just one visit.

Depending on what we’re tackling, here is the typical ‘commitment’ most patients should plan for:

• For Hair Removal: Expect 6–10 sessions, spaced about 4–6 weeks apart to catch the hair in the right growth phase.
• For Pigmentation & Redness: You’ll usually see a major difference in 3–6 sessions, spaced every 3–4 weeks.
• For Skin Rejuvenation: A series of 3–5 sessions is the ‘sweet spot’ for that lasting collagen boost.

Most of our patients find that a quick ‘maintenance’ session once a year is all it takes to keep those results looking fresh and vibrant.

Pros & Cons of IPL

Pros

• Treats multiple issues in one treatment (pigment + redness + texture)
• No downtime for most people
• Faster than some lasers for large areas
• Results look natural

Cons

• Not safe for very dark skin without special filters
• Can sting a bit more than some lasers
• Needs multiple sessions for full results
• Won’t completely remove hair like some true lasers do

IPL vs Laser – What’s the Difference?

Feature	IPL	True Laser (like Alexandrite or ND:YAG)
Light type	Broad spectrum (many wavelengths)	Single wavelength
Best for	Multiple concerns at once	Specific targets (hair, pigment, etc.)
Skin types	Fair to medium	Can be safer for darker skin (ND:YAG)
Pain level	Mild to moderate	Consistent heat or a mild tingle (depending on cooling tech)
Downtime	Very little	Little to none

Final Thoughts

IPL is like the friendly, all-purpose treatment in the world of light-based skin care. It’s not trying to be a miracle worker for every problem, but when your skin has a mix of sun spots, redness, and a little uneven tone, IPL can tackle it all in a few quick sessions. And the glow people get afterward? It’s real.

If you’re considering giving it a try, make sure to visit a clinic. With the help of an experienced technician, we will adjust the settings for your skin type. A good consultation will tell you if IPL is the right choice or a laser may be preferable.

It’s kind of amazing, a flash of light can glow up your face, calm redness or halt hair in its growth-trajectory. If sun damage or uneven skin has been bothering you, IPL might just be the gentle remedy you’ve been searching for.
