Tried Red Light Therapy and noticed a few surprise spots? You’re not alone. Short answer: Red Light Therapy rarely causes breakouts—but “purging” or misuse might. We’re diving into Red Light Therapy Panels, Red Light Therapy Beds, and all the possible skin reactions. Keep reading if your glow-up took a detour.

The Short Answer: Red Light Therapy and Acne
Red light therapy is praised for its calming, anti-inflammatory benefits—particularly for acne-prone skin. However, some users report temporary breakouts or sensitivity after starting. This doesn’t mean it’s making things worse. Understanding how and why these reactions occur can help you maximise results and avoid unnecessary skin setbacks.
Red Light Therapy's Primary Role in Skin Health
How RLT Targets Inflammation and Acne
Red light therapy (RLT) works by penetrating the skin’s surface to reduce inflammation. It soothes redness and helps calm overactive sebaceous glands, which are often linked to acne flare-ups.
RLT doesn’t target bacteria like blue light, but it supports healing and reduces triggers that lead to breakouts.
Stimulating Cellular Repair and Regeneration
RLT boosts cellular energy (ATP), which fuels skin repair and regeneration. This can speed up the healing of existing blemishes and reduce the risk of scarring.
The improved circulation also delivers more oxygen and nutrients to the skin, accelerating recovery from irritation or inflammation.
Promoting Overall Skin Clarity and Healing
Consistent use of red light encourages skin balance over time. By calming irritation and promoting healing, many users report clearer, more resilient skin.
It’s particularly beneficial for those with inflammatory conditions like rosacea, hormonal acne, or skin prone to redness.
Understanding "Skin Purging" After Starting RLT
What is Skin Purging and Why Does it Happen?
Skin purging is a temporary reaction where hidden congestion surfaces as spots. It often occurs when active treatments speed up skin turnover.
Red light therapy doesn’t exfoliate, but it can increase cellular activity enough to trigger mild purging—especially in acne-prone users.
Differentiating Purging from True Breakouts
Purging tends to happen in areas you usually break out, whereas new breakouts can appear in unusual places.
If your skin flares up and then clears within a couple of weeks, it’s likely purging. Ongoing irritation may point to another issue like product sensitivity or overuse.
Typical Duration of a Purging Phase
If you experience purging from RLT, it usually lasts no longer than two to three weeks. During this time, skin may feel more congested before it clears.
If breakouts persist beyond that, or worsen, it’s worth reassessing your skincare or speaking with a professional.
Factors That Might Lead to Apparent Breakouts
Improper Skin Preparation Before Sessions
Using RLT on dirty or oily skin can trap debris, leading to clogged pores. Always cleanse your face thoroughly beforehand to avoid unwanted reactions.
Skipping this step is one of the most common causes of post-treatment breakouts.
Overuse and Exceeding Recommended Treatment Times
Too much of a good thing can irritate your skin. Overuse of red light therapy—especially with strong devices—may lead to overstimulation.
Stick to your device's guidelines to give your skin space to adapt and repair.
Device Type and Wavelength Considerations
Not all red light therapy panels are equal. Some home devices emit infrared wavelengths that penetrate deeper, which might not suit all skin types.
Higher-power devices or red light therapy beds may need shorter exposure for sensitive users.
Interactions with Other Skincare Products (e.g., photosensitising agents)
Using red light therapy alongside ingredients like retinol or AHAs may increase skin sensitivity.
These products can amplify photosensitivity, making your skin more prone to irritation if not spaced or managed correctly.
Maximising Benefits and Minimising Unwanted Reactions
Cleansing Your Skin Thoroughly Before Each Session
A clean face helps red light absorb properly and prevents clogging. Use a gentle cleanser to remove make-up, oil, and environmental grime.
Avoid harsh scrubs before therapy to prevent irritation.
Adhering to Manufacturer's Guidelines (Duration & Frequency)
Each device comes with usage instructions. Following these ensures optimal results while protecting your skin.
Over-treating or holding panels too close can trigger unwanted reactions, especially for beginners.
Starting Slowly, Especially for Sensitive Skin
If you're new to RLT or have reactive skin, begin with shorter sessions. Gradually build up time and frequency to allow your skin to adjust.
This helps avoid unnecessary stress and minimises the chance of purging or breakouts.
The Importance of Consistency
Like any skincare tool, RLT works best with regular use. Skipping sessions or overdoing it can delay results or cause confusion for your skin.
Set a routine that’s sustainable and fits your skin’s needs.
Complementing RLT with Your Skincare Routine

Pairing RLT with Appropriate Cleansers and Moisturisers
Mild, non-comedogenic cleansers and moisturisers pair best with RLT. Look for soothing ingredients like aloe vera or ceramides.
Avoid anything harsh or heavily fragranced right before a session.
Sun Protection is Still Key
Even though red light therapy isn’t UV-based, skin may become more sensitive to sunlight after use.
Daily SPF is essential, especially if you’re also using actives like vitamin C or acids in your routine.
When to Consider Combination Therapies (e.g., Blue Light for Bacteria)
Red light calms inflammation, but doesn’t kill acne-causing bacteria. If breakouts persist, consider combining RLT with blue light therapy.
This duo targets both inflammation and bacteria for clearer, healthier skin.
Recognising and Addressing True Side Effects

Rare Adverse Reactions (Temporary Redness, Dryness, Irritation)
Mild redness or warmth post-treatment is normal and usually fades within minutes. Occasionally, people may experience dryness or slight tingling.
This can often be managed by moisturising immediately after sessions.
When to Discontinue Use and Seek Professional Advice
If you notice burning, stinging, or a worsening skin condition, it’s best to stop using your device. Consult a dermatologist for personalised guidance.
This is especially important if you’re on prescription skincare or have an underlying condition.
Importance of Eye Protection
Always use protective goggles when using high-powered red light therapy panels or beds.
Even though RLT is not UV, prolonged exposure may strain your eyes or cause irritation without protection.
Conclusion: So, Can Red Light Therapy Cause Breakouts?
In most cases, no—but improper use, skin purging, or poor prep can lead to temporary issues. Red light therapy at home is generally safe, especially when done correctly and with the right skincare.
Stick with consistent sessions, listen to your skin, and glow on with confidence.
