Introduction
Acne is one of the most frustrating and persistent skin concerns. Whether it’s hormonal breakouts, cystic acne, facial acne, or post-inflammatory redness, many people struggle to find an effective solution. Acne affects 95% of teenagers and adults at some point during their lives, making it one of the most common skin conditions.
If you’ve tried creams, antibiotics, facials, and LED therapy with little success, you might be wondering: Does Intense Pulsed Light (IPL) therapy actually work for acne?
At Hampstead Aesthetics, we’ve treated many clients in West Hampstead, Hampstead, Swiss Cottage, Camden, Primrose Hill, Belsize Park, St John’s Wood, Queen’s Park, and Finchley Road who suffered from persistent acne and scarring. IPL has become a game-changer for many of them.
Let’s look at the science behind IPL for acne and whether it could be the solution for you.
What is IPL and How Does it Work for Acne?
Intense Pulsed Light (IPL) is a non-invasive light therapy that has gained popularity for treating various skin concerns, including acne. But how exactly does it work? IPL emits high-intensity pulses of light that penetrate deep into the skin, targeting the root causes of acne. The light energy is absorbed by the pigment cells, heating them up and effectively destroying the bacteria responsible for breakouts. This process not only reduces inflammation but also helps to prevent future acne lesions.
What sets IPL apart in treating acne is its ability to address the underlying causes rather than just the symptoms. By reducing inflammation and eliminating acne-causing bacteria, IPL helps to prevent new breakouts and diminish the appearance of existing ones. Additionally, IPL can improve skin tone and texture, leaving your skin looking smoother and more radiant. This makes IPL a comprehensive solution for those struggling with acne and seeking long-term improvements in their skin health.
Understanding Acne Types and Causes
Acne is a complex skin condition that can manifest in various forms, including blackheads, whiteheads, papules, pustules, nodules, and cysts. Understanding the different types of acne and their causes is crucial for effective treatment.
There are several types of acne, including: Hormonal changes often trigger acne by leading to excess oil production, which clogs pores and contributes to breakouts.
Comedonal Acne: Characterized by blackheads and whiteheads, this type of acne occurs when dead skin cells and oil clog the pores. It’s often seen in acne prone skin and can be effectively managed with proper skincare routines and treatments.
Inflammatory Acne: Marked by redness, swelling, and pus-filled pimples, inflammatory acne occurs when bacteria infect the clogged pores. This type of acne can be more challenging to treat and often requires targeted acne treatments.
Cystic Acne: A severe form of acne, cystic acne is characterized by large, painful cysts that can cause scarring. Treating acne of this severity often involves more aggressive treatments, such as laser therapies or prescription medications.
Acne can be caused by a combination of factors, including:
Hormonal Fluctuations: Changes in hormone levels, such as those experienced during puberty, menstruation, pregnancy, and menopause, can lead to acne. Hormonal acne is particularly common and can be persistent.
Genetics: If your parents had acne, you may be more likely to develop it as well. Genetic predisposition plays a significant role in how your skin reacts to various triggers.
Stress: High stress levels can increase the production of hormones that contribute to acne. Managing stress through lifestyle changes can help in treating acne.
Poor Skin Care: Not removing makeup properly, using harsh skin care products, and not protecting the skin from the sun can all contribute to acne. A good skincare routine is essential for maintaining clear skin.
Diet: Consuming a diet high in processed foods, sugar, and dairy products can lead to inflammation and increase the risk of acne. Dietary changes can sometimes improve skin condition.
How Intense Pulsed Light Treats Acne
IPL therapy uses intense pulsed light technology to target multiple acne triggers at once. IPL uses intense light to target skin imperfections, promoting healing and improving skin texture:
1️⃣ Kills Acne-Causing Bacteria (P. acnes) – IPL emits wavelengths that destroy the bacteria responsible for breakouts.
2️⃣ Reduces Sebum Production – The light penetrates deep into the skin to shrink overactive oil glands, leading to less clogging of pores.
3️⃣ Calms Inflammation – Red and swollen breakouts are reduced as IPL shrinks blood vessels and targets redness.
4️⃣ Speeds Up Skin Healing – IPL stimulates collagen production, helping to fade acne scars and improve skin texture.
In addition to IPL, LED therapy can also be used to target acne-causing bacteria and reduce inflammation.
🔬 Scientific Evidence: A 2023 study in the Journal of Clinical and Aesthetic Dermatology found that IPL treatments reduced acne lesions by 85% after four sessions. Patients also reported less oiliness and faster healing of breakouts. Patients usually need multiple IPL sessions to notice significant changes.
What Type of Acne Can IPL Help With?
IPL is effective for:
✅ Mild to Moderate Acne – Whiteheads, blackheads, and papules respond well to IPL.
✅ Hormonal Acne – IPL can reduce the redness and swelling of cystic breakouts.
✅ Acne Scars & Red Marks – It fades post-inflammatory hyperpigmentation (PIH), smooths out rough texture, and significantly improves the condition of skin affected by acne scarring.
✅ Oily Skin & Large Pores – By shrinking oil glands, IPL reduces excess sebum and pore congestion.
Laser treatments can also be effective for severe acne.
⚠️ Who Should Avoid IPL for Acne?
If you have very deep cystic acne, alternative treatments like prescription medication or laser therapy may be more effective.
Darker skin tones (Fitzpatrick IV-VI) may be at risk of post-treatment pigmentation changes. A consultation is recommended.

IPL Treatment Considerations and Precautions
While IPL treatment can be an effective way to treat acne, there are several considerations and precautions to keep in mind.
Skin Type: IPL treatment is most effective for individuals with fair skin. Those with darker skin tones may experience more side effects, such as hyperpigmentation. It’s crucial to consult with a specialist to determine if IPL is suitable for your skin type.
Acne Severity: IPL treatment is best suited for mild to moderate acne. Severe acne may require more aggressive treatments, such as laser therapy or chemical peels. Understanding the severity of your acne can help in choosing the right treatment.
Pregnancy and Breastfeeding: IPL treatment is not recommended for pregnant or breastfeeding women, as the effects on the fetus or baby are not well understood. Always consult with your healthcare provider before starting any new treatment.
Medications: Certain medications, such as isotretinoin, can increase the risk of side effects from IPL treatment. It’s important to disclose all medications you are taking to your practitioner.
Sun Exposure: Avoiding sun exposure before and after IPL treatment can help minimize the risk of side effects. Using a high SPF sunscreen is essential to protect your skin and maintain the results of the treatment.
Topical treatments: Using topical treatments like retinoids and salicylic acid can enhance the effectiveness of IPL by preparing the skin and reducing inflammation.
IPL Acne Treatment: Effectiveness and Benefits
When it comes to acne treatment, IPL has proven to be a highly effective solution. Studies have shown that IPL can significantly reduce the severity and frequency of acne breakouts. But the benefits don’t stop there. IPL also improves skin texture and tone, making it a versatile treatment option for those looking to enhance their overall skin appearance. One of the standout features of IPL acne treatment is its ability to reduce the appearance of acne scars and hyperpigmentation, giving you a clearer and more even complexion.
Another major advantage of IPL is that it is a relatively painless and non-invasive procedure. Unlike surgical options, IPL requires no downtime, allowing you to return to your daily activities almost immediately. This makes it an attractive option for those who want effective results without the hassle of recovery time. Moreover, IPL can target multiple skin concerns simultaneously, from fine lines and wrinkles to unwanted hair, making it a comprehensive solution for various skin issues.
Combining IPL with Other Treatments
While IPL is highly effective on its own, combining it with other treatments can yield even better results. For instance, chemical peels can exfoliate the skin and remove dead skin cells, allowing the IPL treatment to penetrate deeper and work more effectively. Laser hair removal can also be used alongside IPL to target unwanted hair and reduce the appearance of acne, providing a dual benefit.
Topical treatments can further enhance the effectiveness of IPL. Retinoids, for example, help to unclog pores and reduce inflammation, while salicylic acid exfoliates the skin and removes dead skin cells. By integrating these skincare treatments, you can achieve a more comprehensive approach to treating acne and improving overall skin health.
IPL is versatile enough to address a range of skin concerns, from severe acne and facial acne to acne scarring and acne-prone skin. However, it’s always best to consult with a qualified dermatologist or skincare specialist to determine the most effective treatment plan for your specific needs. Combining IPL with other treatments can provide a holistic approach to achieving clearer, healthier skin.
What to Expect During an IPL Treatment for Acne
Many patients ask, “Does IPL hurt?” or “How many sessions will I need?” Here’s what to expect:
✔ Treatment Duration:**20-30 minutes depending on the treatment area.
✔ Sensation: Feels like a mild snapping sensation but is well-tolerated.
✔ Downtime: Minimal—expect mild redness for a few hours.
✔ Number of Sessions: Most patients see results after 3-5 treatments, spaced 2-4 weeks apart.
✔ IPL Device: The IPL device emits light to target acne, pigmentation, and other skin issues.
Before IPL treatment begins, a cooling gel is applied to the skin to ensure comfort and protect the skin.
Some patients also combine IPL with LED therapy for enhanced results.
🔬 Scientific Evidence: A 2024 study in the Journal of Investigative Dermatology found that patients who underwent 5 IPL treatments saw a 70% reduction in active breakouts within 12 weeks.
Pre & Post-Treatment Care for IPL Acne Therapy
Before Your IPL Session
📌 Avoid sun exposure for 2 weeks to prevent irritation.
📌 Stop using retinol, acids, and exfoliants 5 days before treatment.
📌 No recent tanning—this can increase the risk of hyperpigmentation.
After Your IPL Session
📌 Expect mild redness for a few hours—this fades quickly.
📌 Breakouts may purge for 1-2 weeks before clearing up.
📌 Wear SPF 50 daily to protect your skin and maintain results. Most people experience redness or warmth after IPL treatment, but these symptoms usually disappear within a few hours.
Potential Risks and Side Effects of IPL
While IPL treatment is generally considered safe, there are potential risks and side effects to be aware of.
Redness and Swelling: Mild redness and swelling are common side effects of IPL treatment. These effects usually resolve on their own within a few hours. It’s a normal part of the healing process and indicates that the treatment is working.
Bruising: Some individuals may experience bruising after IPL treatment. This is usually temporary and resolves on its own within a few days. Gentle skincare and avoiding harsh products can help speed up recovery.
Hyperpigmentation: IPL treatment can cause hyperpigmentation, especially in individuals with darker skin tones. This is usually temporary and can be treated with topical creams or further IPL treatments. It’s important to follow post-treatment care instructions to minimize this risk.
Infection: As with any invasive treatment, there is a risk of infection with IPL treatment. This can be minimized by following proper aftercare instructions and keeping the treated area clean.
Scarring: IPL treatment can cause scarring, especially if the skin is not properly cared for after treatment. Adhering to aftercare guidelines and avoiding picking at the treated area can help prevent scarring.
Topical treatments: Using topical treatments like hydrocortisone cream can help manage redness and swelling after IPL treatment.
By understanding these potential risks and side effects, you can make an informed decision about whether IPL treatment is right for you. Always consult with a qualified practitioner to discuss your specific needs and concerns.
