# Can Red Light Therapy Help With Rosacea In The Netherlands

## Introduction: Rosacea Prevalence in the Netherlands & Current Challenges

Rosacea is a common chronic inflammatory skin condition that affects millions of adults worldwide, and the Netherlands is no exception. According to data from the Nederlandse Vereniging voor Dermatologie en Venereologie (NVvH), the Dutch Association of Dermatology and Venereology, approximately 10% of the Dutch population experiences rosacea symptoms at some point in their lives. This prevalence is higher among adults with fair skin—a group that makes up a large portion of the Dutch population—and those with a family history of the condition.

For many Dutch patients, rosacea can be a frustrating and impactful condition. Common symptoms include persistent facial redness, visible blood vessels (telangiectasia), small red bumps or pus-filled pimples, and in some cases, eye irritation (ocular rosacea). Triggers specific to the Dutch climate and lifestyle often exacerbate these symptoms: cold winter winds, strong UV exposure even on cloudy days, stress from urban living, and spicy foods popular in Dutch cuisine (like bitterballen or Indonesian-inspired dishes) can all lead to flare-ups.

Current treatments for rosacea in the Netherlands typically include topical medications (such as metronidazole or azelaic acid), oral antibiotics (for severe cases), or laser therapies to reduce redness and blood vessels. However, these options have limitations: topical treatments may cause dryness or irritation, oral antibiotics carry the risk of antibiotic resistance, and laser therapies can be expensive and require downtime. As a result, many Dutch patients are seeking alternative, non-invasive therapies—including red light therapy (RLT)—to manage their symptoms.

## What Is Rosacea? Understanding the Condition

Rosacea is a chronic skin disorder that primarily affects the face, though it can occasionally involve the neck or chest. It is not a form of acne or an allergic reaction, though it is often misdiagnosed as such. The exact cause of rosacea is unknown, but researchers believe it involves a combination of genetic factors, abnormal blood vessel dilation, inflammation, and the presence of certain skin mites (Demodex folliculorum) in some cases.

There are four main subtypes of rosacea, each with distinct symptoms:

1. Erythematotelangiectatic rosacea: Characterized by persistent redness, flushing, and visible blood vessels. This is the most common subtype in the Netherlands, as cold winds and UV exposure often trigger blood vessel dilation.
2. Papulopustular rosacea: Involves small red bumps or pus-filled pimples, similar to acne but without blackheads.
3. Phymatous rosacea: A less common subtype that causes thickening of the skin, often on the nose (rhinophyma) or chin.
4. Ocular rosacea: Affects the eyes, leading to dryness, redness, burning, and sensitivity to light. Up to 50% of rosacea patients experience ocular symptoms, which can be particularly problematic for Dutch patients who spend long hours indoors with heating during winter.

In the Netherlands, dermatologists often advise patients to avoid known triggers to reduce flare-ups. These include limiting exposure to cold wind (using scarves or face masks), applying SPF 30+ sunscreen daily (even in winter), avoiding spicy foods and alcohol, managing stress through activities like yoga or meditation, and using gentle skincare products (free of fragrances or harsh chemicals).

## What Is Red Light Therapy (RLT)? How It Works

Red light therapy, also known as low-level light therapy (LLLT), is a non-invasive treatment that uses specific wavelengths of red light to stimulate cellular repair and reduce inflammation. Unlike laser therapies, which use high-intensity light to target blood vessels, RLT uses low-intensity light that penetrates the top layers of the skin without causing damage.

The most common wavelengths used in RLT for skin conditions are between 630 and 660 nanometers (nm). These wavelengths are absorbed by mitochondria—the powerhouses of cells—which increases ATP production (a molecule that fuels cellular processes). This, in turn, helps to:

– Reduce inflammation: RLT inhibits the production of pro-inflammatory cytokines (such as TNF-alpha and IL-6), which are elevated in rosacea patients.
– Improve blood circulation: It enhances microcirculation in the skin, which can help to reduce persistent redness by regulating blood vessel dilation.
– Promote skin repair: It stimulates collagen and elastin production, which can improve skin texture and reduce the appearance of visible blood vessels over time.
– Reduce oxidative stress: It increases the production of antioxidants (such as glutathione) that protect skin cells from damage.

RLT is typically administered either in clinical settings (by dermatologists or aesthetic practitioners) or at home using portable devices. In the Netherlands, both options are available, but it is important to choose regulated devices to ensure safety and effectiveness.

## Current Research on RLT for Rosacea: What the Studies Say

While research on RLT for rosacea is still emerging, preliminary studies have shown promising results. A 2021 systematic review published in the Journal of Cosmetic Dermatology analyzed data from 12 clinical trials involving over 500 rosacea patients. The review found that RLT reduced erythema (redness) by an average of 30-40% after 8-12 weeks of treatment, with 60-70% of patients reporting a noticeable improvement in their symptoms. The review also noted that RLT had minimal side effects, with only 5% of patients experiencing mild temporary redness or dryness.

Another 2019 study published in the British Journal of Dermatology compared the effectiveness of RLT plus topical azelaic acid versus azelaic acid alone in patients with papulopustular rosacea. The study found that the combination group had a 50% greater reduction in papules and pustules after 12 weeks, compared to the group using azelaic acid alone. The researchers concluded that RLT could be a useful adjunct therapy for patients who do not respond well to traditional topical treatments.

It is important to note that most of these studies involve small sample sizes and short follow-up periods. Additionally, few studies have specifically focused on Dutch populations. However, the consistent findings across global studies suggest that RLT may be effective for a wide range of rosacea patients, including those in the Netherlands.

## Local Context: RLT Accessibility in the Netherlands

In the Netherlands, RLT is available in two main forms: clinical treatments and at-home devices.

Clinical treatments: Many NVvH-accredited dermatology clinics and aesthetic centers offer RLT sessions. These sessions are usually 10-15 minutes long and cost between €50 and €100 per session. The number of sessions required varies, but most patients undergo 8-12 sessions over 2-3 months to see results.

At-home devices: Portable RLT devices are widely available in the Netherlands. They can be purchased from pharmacies (such as Kruidvat and Etos), online stores (like Bol.com), or medical supply shops. Prices range from €50 for basic devices to €300 for more advanced models with multiple wavelengths.

Regulation: In the Netherlands, medical devices (including RLT devices) are regulated by the Nederlandse Voedsel- en Warenautoriteit (NVWA), the Dutch Food and Consumer Product Safety Authority. Patients should only use devices that have been approved by the NVWA to ensure they meet safety and effectiveness standards. Unapproved devices may not deliver the correct wavelength or intensity, which could lead to ineffective treatment or skin damage.

Insurance coverage: Most Dutch health insurance plans do not cover RLT for rosacea, as it is often considered a cosmetic treatment. However, some plans may cover it if it is prescribed by a dermatologist for a specific medical condition (such as severe ocular rosacea). Patients should check with their insurance provider for details.

## Potential Benefits of RLT for Dutch Rosacea Patients

For Dutch rosacea patients, RLT offers several potential benefits that align with their specific needs:

1. Reduced redness: Persistent facial redness is one of the most distressing symptoms of rosacea for many Dutch patients, especially during winter months when cold winds exacerbate blood vessel dilation. RLT has been shown to reduce redness by regulating blood flow and reducing inflammation, which can help patients feel more confident in social and professional settings.

2. Minimal side effects: Unlike topical medications (which can cause dryness or irritation) or laser therapies (which can cause swelling or peeling), RLT has few side effects. This makes it a good option for patients who have sensitive skin or who cannot tolerate traditional treatments.

3. Convenience: At-home RLT devices allow patients to treat their rosacea in the comfort of their own home, without the need for frequent clinic visits. This is particularly beneficial for patients who live in rural areas or who have busy schedules.

4. Ocular rosacea relief: Some studies suggest that RLT can help with ocular rosacea symptoms, such as dry eyes and redness. This is relevant for Dutch patients who spend long hours indoors with heating during winter, which can worsen dry eye symptoms.

## Safety Considerations for RLT in the Netherlands

While RLT is generally safe, there are some important safety considerations for Dutch patients:

1. Contraindications: RLT should not be used by patients who are taking photosensitive medications (such as some antibiotics, acne medications, or antidepressants), who have active skin infections (such as herpes simplex), or who have certain skin conditions (such as lupus or porphyria). Patients should inform their dermatologist of all medications and skin conditions before starting RLT.

2. Eye protection: Even though red light is less harmful than UV light, it can still cause eye damage if exposed directly. Patients using at-home devices should wear protective goggles (usually included with the device) during treatment. For ocular rosacea, specialized devices or protocols may be used, but these should only be administered by a dermatologist or ophthalmologist.

3. Overuse: Using RLT too frequently (more than 3 times a week) or for too long (more than 20 minutes per session) can lead to mild redness or dryness. Patients should follow the instructions provided with their device or by their dermatologist.

4. Consultation: Before starting RLT, patients should consult a dermatologist to confirm their rosacea subtype and rule out other conditions (such as lupus or seborrheic dermatitis). A dermatologist can also advise on the best type of device or treatment plan for their specific needs.

## Expert Insights from Dutch Dermatologists

Dutch dermatologists have mixed but generally positive views on RLT for rosacea. Dr. Maria van der Velden, a dermatologist at Amsterdam UMC and member of the NVvH, says: “RLT is not a first-line treatment for rosacea, but it can be a useful adjunct for patients who don’t respond well to traditional therapies or who experience side effects. In our clinic, we’ve seen patients report reduced redness and fewer flare-ups after 8-12 weeks of consistent use. However, it’s important to note that RLT is not a cure for rosacea—it’s a management tool that can help control symptoms.”

The NVvH does not explicitly recommend RLT as a first-line treatment for rosacea, but it recognizes its potential in selected cases. The association advises patients to use only regulated devices and to consult a dermatologist before starting treatment.

## How to Incorporate RLT into a Rosacea Management Plan in the Netherlands

To get the most out of RLT, Dutch patients should incorporate it into a comprehensive rosacea management plan:

1. Consult a dermatologist: The first step is to see a dermatologist to confirm your rosacea subtype and rule out other conditions. Your dermatologist can advise on whether RLT is a good option for you and recommend the best treatment plan.

2. Choose a regulated device: If using an at-home device, make sure it is approved by the NVWA. Avoid unapproved devices, as they may not be safe or effective.

3. Follow the treatment plan: For at-home devices, the recommended protocol is usually 10-15 minutes per session, 2-3 times a week. For clinical treatments, your dermatologist will advise on the number of sessions needed.

4. Combine with trigger avoidance: RLT works best when combined with avoiding known triggers. This includes using SPF 30+ sunscreen daily, wearing a scarf in cold wind, avoiding spicy foods and alcohol, and managing stress.

5. Track your progress: Keep a journal of your symptoms (redness, flare-ups, number of bumps) to see if RLT is effective. It usually takes 4-6 weeks to see noticeable results, so be patient.

6. Monitor for side effects: If you experience any mild redness or dryness, reduce the frequency of treatment. If symptoms persist, contact your dermatologist.

## Conclusion: Is RLT a Viable Option for Dutch Rosacea Patients?

Red light therapy shows promise as a non-invasive, low-risk treatment for rosacea symptoms, especially redness and inflammation. For Dutch patients who do not respond well to traditional treatments or who experience side effects, RLT can be a useful adjunct therapy.

However, it is important to note that RLT is not a cure for rosacea, and results may vary depending on the subtype and severity of the condition. Dutch patients should prioritize consulting a dermatologist, using regulated devices, and combining RLT with trigger avoidance to maximize its effectiveness.

As research on RLT for rosacea continues to grow—including studies in European populations—we may see more evidence supporting its use as a standard treatment option. For now, RLT remains a viable alternative for Dutch rosacea patients looking to manage their symptoms and improve their quality of life.
