Is red light therapy safe for melasma?

Melasma—those uneven brown patches on your face—can be frustrating and undermine your self-confidence. While makeup and creams may cover it up temporarily, you likely want clearer skin permanently. But certain treatments come with side effects or damage skin further. Red light therapy provides a safe, natural option for improving melasma by addressing its underlying causes.

red light therapy for melasma

Red light gently penetrates skin to correct the melanin imbalance causing discoloration. Extensive research shows red light therapy successfully and safely improves melasma without side effects when protocols are properly followed. Read on to learn how red light can fade spots by targeting melanin production at the cellular level without damaging your skin.

what is melasma?

Melasma is a common skin condition where brown or grayish patches appear on the face, especially on the cheeks, nose, forehead and chin. The discoloration often develops slowly over time, but can also emerge suddenly after pregnancy, birth control use, or sun exposure. While not a dangerous condition, melasma is stubborn and notoriously difficult to treat. But understanding what causes it gives clues about how to safely fade those dark spots.

Causes of Melasma

Melasma arises from a combination of genetic, hormonal, and lifestyle triggers that stimulate melanocyte cells in the skin to produce excess melanin pigment. Key contributing factors include:

  • Sun Exposure – UV radiation from the sun directly stimulates melanin production and is a primary driver of melasma, especially in those with darker skin tones.
  • Hormones – Elevated estrogen and progesterone during pregnancy, birth control use, or hormone therapy overstimulate melanocytes and commonly trigger melasma.
  • Genetics – A family history and ethnic background with more active melanocytes increases risk for hyperpigmentation like melasma.
  • Stress – Chronic stress and inflammation due to conditions like thyroid disease or autoimmune disorders can indirectly increase pigmentation.
  • Skin Damage – Injury from burns, acne breakouts, or procedures like dermabrasion can induce excess melanin, especially around damaged areas.
  • Nutrient Deficiencies – Being low in vitamins and antioxidants like vitamin E, zinc, and copper may impair melanin regulation.
  • Medications – Certain drugs like anticonvulsants and antibiotics associated with photosensitivity can promote pigmentation.

Once you understand these common melasma triggers, it becomes clearer how to address it safely and naturally.

Causes of Melasma

Conventional Melasma Treatments

Given how frustrating melasma can be when patches darken your skin, you’ve likely tried fading creams containing hydroquinone, kojic acid or retinoids like tretinoin. These can gradually lighten skin over time when consistently applied.

Stronger chemical peels with glycolic or trichloroacetic acid also exfoliate away pigmented surface layers of skin. However, these acids can irritate sensitive skin and make it more sun-sensitive.

Other options like microneedling or microdermabrasion physically slough off pigmented skin to promote renewal. But they involve needles or abrasion that can further damage skin if not done properly.

And laser or IPL treatments directly target and destroy melanin deposits with concentrated light beams. Yet, they carry risks of burns and post-inflammatory hyperpigmentation if not administered at the ideal settings for your skin type.

As you can see, while conventional treatments may lighten melasma, they also come with disadvantages like irritation, side effects, or potential damage that can worsen pigmentation. A safer option is needed.

What is Red Light Therapy?

Red Light Therapy Offers a Natural Approach to Improving Melasma, Red light therapy harnesses specific wavelengths of visible red light and near infrared light to gently treat melasma and fade discoloration. Also called photobiomodulation, it works from the inside out to address the root causes of excess melanin production.

How does red light therapy help melasma?

There are several mechanisms by which red light therapy reduces excess melanin production and fades melasma:

  • Lowers Melanin Synthesis – Red light directly inhibits the activity of tyrosinase – the key enzyme involved in melanin synthesis – to reduce pigment production.
  • Corrects Cell Communication – It optimizes communication pathways between melanocyte cells and keratinocytes to normalize pigment production.
  • Balances Skin Cell Turnover – The light helps regulate the growth and turnover of pigmented skin cells for gradual rejuvenation.
  • Reduces Inflammation – Light decreases inflammatory compounds that drive excess melanin formation. It also boosts cell stress tolerance.
  • Improves Circulation – Better blood flow provides oxygen and nutrients to help normalize melanin production and cell renewal.
  • Acts as Gentle Exfoliant – Red light gently lifts off surface pigmented cells as newer, less pigmented layers form underneath for natural lightening.
  • Enhances Skin Clarity – It improves skin tone, radiance and clarity for a more even, luminous complexion.

These diverse effects make red light therapy a truly comprehensive natural solution for improving melasma from the inside out.

Red Light Therapy Helps Melasma Science Research

With considerable evidence for its efficacy, red light therapy is gaining recognition as an effective natural option for improving stubborn melasma.

– A 2022 study in the journal Laser Medical Science concluded that red light therapy successfully reduced melasma area and severity indices.[1]

– A 2012 study found that red light therapy reduced melasma and post-inflammatory hyperpigmentation.[2]

Is red light therapy safe for melasma?

Yes, indeed! Red light therapy is a safe and natural approach to managing melasma. Unlike some skin treatments, it doesn’t involve any harsh chemicals that can cause side effects or further irritate your skin. Instead, red light therapy uses natural light to stimulate your body’s own healing mechanisms.It does not damage the outer layer of the skin and has minimal side effects.


Backed by an array of positive research studies and real life patient success stories, red light therapy stands out as superior option compared to risky laser genesis and irritating chemical peels. While patience and dedication to treatment protocols is required, red light can gradually restore a clearer, more vibrant and evenly-toned complexion by addressing melasma at its source. Give your skin the chance to rediscover its natural radiance.
