At Zap Laser Center, we understand the struggles that come with acne and its impact on your self-esteem. The good news is that red light therapy is a gentle, science-backed option that might help you find relief. In this post, we’ll dive into everything you need to know about this treatment: the benefits of red light therapy for acne, how it works, important considerations, and the potential results. So, let’s discover together how red light therapy can be a supportive step towards improving your confidence and achieving the healthy skin you deserve!
What is Red Light Therapy for Acne and How Does It Work
Let’s start by refreshing the basics: Red light therapy (RLT) is a noninvasive treatment that uses low-level red wavelengths of light to stimulate your skin’s natural healing processes. NASA originally studied it for its wound-healing potential, but it has found its way into dermatology and cosmetology as a promising option for common skin conditions, such as acne.
Red light therapy works by penetrating deeply into the skin to boost cellular energy. Skin cells absorb this light and produce more adenosine triphosphate (ATP), which fuels the cells, allowing them to repair and regenerate more efficiently. So, does red light therapy help with acne? Research and expert opinions suggest that it does. Unlike blue light therapy, which targets and kills acne-causing bacteria, red light therapy reaches deeper layers of the skin, affecting the sebaceous glands and calming inflammation. Practically speaking, this means that red light therapy can help reduce the size of inflamed, red pimples and promote faster healing of a breakout.
Key Benefits of Red Light Therapy for Acne
Red Light Therapy offers multiple benefits for both active breakouts and post-acne scars and redness. Let’s look at the advantages for each situation:
For Active Acne
- Red light therapy serves as an anti-inflammatory agent, soothing the skin and alleviating the redness and pain associated with inflammatory acne lesions, including papules, pustules, and cysts.
- Red light therapy can also help resolve acne lesions more quickly because it energizes cellular repair mechanisms. You’ll notice pimples shrink and flatten faster.
- There is also evidence suggesting that red light may help regulate oil production in the skin, potentially leading to fewer clogged pores and a reduction in new pimples over time. Less oily skin is generally less prone to acne.
For Acne Scars and Post-Inflammatory Marks
Acne is not just about having active pimples; it can also leave scars and dark spots on your skin. Red light therapy can also help with these issues:
- Red light treatment helps skin by activating fibroblasts, the cells that produce collagen and elastin. More collagen means your skin has more material to heal itself, which can make acne scars look softer.
- Red light therapy can help reduce post-inflammatory hyperpigmentation, which are the dark spots left after a pimple heals. This therapy speeds up skin cell turnover and repair, helping to fade these dark spots faster than they would on their own.
- Finally, red light therapy enhances circulation, allowing more oxygen and nutrients to reach the skin, which helps promote an even complexion —a must for effective scar treatment.
Other Common Benefits
In addition to addressing acne and its scars, red light therapy provides several additional benefits for your skin and overall wellness, including:
- Enhanced skin rejuvenation and wrinkle reduction.
- Compatibility with all skin types, including very sensitive skin.
- It helps with various skin problems, including rosacea.
- Safety as a complementary treatment alongside other acne therapies.
Important Considerations Before Starting
Now, before you book your first red light therapy session, it’s important to understand if this treatment is right for you and how to approach it for the best results. Below are five important considerations:
1. Who Should Use Red Light Therapy
As mentioned before, red light therapy is suitable for all skin tones and types, so you don’t need to worry about the sensitivity of your skin. When it comes to acne, this treatment is effective for inflammatory, moderate acne. However, if you have severe acne or widespread acne breakouts, it is always recommended to consult with your dermatologist first before using red light therapy as a complementary treatment.
Additionally, if you are taking Accutane (isotretinoin) or other strong acne medications, you should also consult with a dermatologist, as these can increase skin sensitivity to light.
2. Risks and Possible Side Effects
One reassuring aspect of red light therapy is its low-risk profile. This treatment is noninvasive and gentle, resulting in minimal side effects. When used correctly, RLT typically does not lead to significant short-term side effects. However, some individuals may experience mild and temporary effects, such as slight redness, a warm sensation, or dryness in the treated area. The primary “risk” usually arises from overuse or misuse of devices. Therefore, we always recommend opting for professional treatments rather than home light devices or red light therapy masks, which are effective but must be used with caution.
3. Frequency & Duration
Red light therapy is not a one-time treatment; it usually requires a series of treatment sessions to achieve noticeable improvements. We typically recommend coming in for multiple sessions (3 to 5 times per week) at the beginning. Each session lasts around 10 to 20 minutes of actual light exposure per area. This frequency aligns with clinical studies, which found that many individuals experienced the best results with a few sessions each week over a period of a couple of months.
4. Results Time
One of the most common questions we receive is about the red light therapy results time. Typically, improvements occur in stages. In the first few weeks, you may notice a reduction in inflammation. Around weeks 4 to 6, users who are consistent with their treatment often see visible changes. This may include fewer new breakouts, faster healing of existing blemishes, and a subtle “healthy glow” as your skin cells become more active. A review of clinical data revealed that many users experienced noticeable improvements in skin clarity and texture by the one-month mark, with further progress by week 10.
5. Preparation Before the Treatment
Preparing for a red light therapy session is simple, but a few small steps can ensure you get the maximum benefit and stay comfortable. Here are some tips to follow before you come in for your treatment:
- Arrive with clean, bare skin. A lightweight moisturizer is enough.
- Pause harsh skincare products and topical treatments with actives.
- Stay out of the sun for 48-24 hours before your treatment.
- Drink a lot of water, so your cells can absorb light more efficiently.
- Communicate any recent skin changes so the technicians can take the necessary measures.

What to Expect During and After Treatment
If you choose Zap Laser Center, we will guide you to a treatment room and ensure your comfort during your red light therapy session. If you’re treating your face, which is the most common area for acne, you will either sit in a reclined chair or lie down. We will provide you with a pair of protective goggles to shield your eyes from the bright LEDs, and then we will turn on the lights. Most people experience little to no sensation during the treatment, apart from a gentle, painless warmth. Throughout the exposure, you won’t feel any sudden changes—no tingling or vibration, just a steady warm light.
After your treatment, there is no downtime; your skin isn’t wounded or sensitized as it might be after more aggressive treatments. You can go right back to your day as usual, with no need to “recover.” You may notice a mild rosy hue due to increased circulation. We recommend some aftercare tips, such as applying a light moisturizer immediately after treatment, using sunscreen, and avoiding exposure to active ingredients for at least 24 hours.
Real Results: What Users and Experts Say
Nothing speaks louder than real-world outcomes. To conclude this blog, we have gathered insights from clinical experts and individuals who have used red light therapy for their acne treatment:
Clinical Studies
Research to date shows promising efficacy. In one review of over 1,000 acne patients using light therapies, 89–92% of people achieved at least a partial clearing of their acne lesions when red light therapy (often combined with blue light) was part of their regimen. Another study focusing on red light alone noted a steady improvement, with about 77% of participants responding positively by the 10-week mark.
Dermatologist insights:
Dermatologists highlight that red light therapy reduces inflammation at the cellular level, leading to less redness, swelling, and discomfort in acne lesions. They also emphasize the role of red light in healing: by stimulating collagen and improving blood flow, it helps existing pimples heal faster and supports the skin’s repair of acne damage.
Real users’ experiences
Many individuals have shared personal success stories. For example, some of our clients at Zap Laser Center who had persistent acne saw significant calming of their skin after about a month of regular red light sessions. Others love that their acne scars started softening and fading, giving them a smoother skin texture than they’d had in years.
