Red Light Therapy for Age Spots: What Results to Expect

Brown, flat spots appearing on your hands, face, or shoulders can feel like unwelcome reminders of sun exposure over the years. 

Left unchecked, these age spots may darken, multiply, and make skin look uneven, impacting confidence more than you might expect. 

Fortunately, red light therapy offers a promising, non-invasive approach to reduce pigmentation and restore a smoother, youthful appearance.

• Reduce Age Spots Safely: Red light therapy can fade pigmentation and even skin tone without harsh chemicals.
  
  

• Follow the Right Routine: Use 630–660 nm red light for 10–20 minutes, 3–5 times a week, and be consistent for best results.
  
  

• Protect and Prep Your Skin: Apply sunscreen, moisturize, and keep skin clean to maintain and enhance results.
  
  

• Support Skin Health Daily: Hydrate, exfoliate, and use brightening ingredients like Vitamin C to prevent new dark spots.
  
  

• Boost Overall Skin Radiance: Red light therapy stimulates collagen, circulation, and healing, improving texture, tone, and fine lines.

Age spots and dark spots are small, flat patches of skin that appear darker than the surrounding area, most commonly on the face, hands, shoulders, and arms. 

They often vary in size and can range from light brown to black, sometimes causing cosmetic concern but rarely leading to physical discomfort. 

These spots are typically triggered by prolonged sun exposure, aging, hormonal changes, or skin inflammation, with genetics sometimes playing a role. 

Scientists believe they form due to an accumulation of melanin, the skin’s natural pigment, produced by melanocytes, which becomes concentrated in certain areas after repeated UV damage or cellular stress. 

Essentially, age spots are the skin’s visible record of long-term exposure to sunlight and other environmental factors.

Red light therapy has shown promising results in reducing age spots and improving overall skin tone. 

Studies, including those highlighted by the International Journal of Molecular Sciences, indicate that red light at wavelengths of 630–660 nm can help fade pigmentation by reducing melanin production and promoting cellular turnover. 

Clinical trials have reported noticeable improvements in hyperpigmentation, melasma, and sun spots after consistent use, typically 10–20 minutes per session, 2–3 times per week, over at least three months. 

Combining red and near-infrared light can enhance benefits, addressing both pigmentation and signs of aging like fine lines and wrinkles. 

Importantly, research confirms that red light therapy is a safe, non-invasive treatment with minimal side effects, making it a gentle alternative to harsh chemical exfoliants. 

By soothing inflammation and brightening dull skin, it supports a more even, radiant complexion over time. 

While more studies are needed to refine protocols, current evidence underscores red light therapy’s potential as an effective, patient-friendly approach to managing age spots and photoaging.

• Choose the Right Device: Select a quality home device with a wavelength of 630–660 nm.
  
  

• Prep Your Skin: Clean and dry your skin before each session.
  
  

• Session Timing: Use the light for 10–20 minutes, 3–5 times a week for best results.
  
  

• Be Patient: Expect noticeable fading after 4–8 weeks of consistent use.
  
  

• Protect Your Skin: Apply sunscreen and moisturizer to maintain results.

Too much sun exposure triggers dark spots and uneven skin tone. UV rays cause the skin to produce excess melanin, leading to hyperpigmentation. 

Prevent this by using a broad-spectrum sunscreen with SPF 30 or higher every day. Reapply every two hours, especially when outdoors or sweating. 

UV rays penetrate clouds, so wear sunscreen even on cloudy days. Combine it with gentle cleansing, antioxidants, and moisturizer to keep skin smooth, bright, and even-toned.

Keeping your skin hydrated and moisturized helps strengthen its natural barrier, locking in moisture and protecting against environmental stressors that can trigger dark spots. 

For example, one study found that a moisturizer with yeast extract improved skin barrier function, supported beneficial microbiome balance, and reduced inflammation markers, helping prevent pigmentation. 

According to the Journal of Clinical Medicine, maintaining this barrier is key to keeping skin even-toned and resilient.

Adding Vitamin C to your skincare routine can help stop dark spots before they start. It works by slowing melanin production and protecting your skin from damage caused by the sun. 

Using it regularly can make your skin look brighter and more even. One review of studies found Vitamin C is very effective at lightening hyperpigmented spots on skin and gums. 

Another analysis of 31 clinical trials showed it reduces sun-induced pigmentation, especially at higher doses, making it a safe and powerful tool to keep your skin glowing.

A healthy, radiant complexion starts with regular exfoliation. As noted in Plastic and Reconstructive Surgery Global Open, our skin’s natural cell turnover slows with age, causing dullness and buildup of dead cells that make pores appear larger and skin rougher. 

Exfoliation, whether chemical or physical, helps sweep away these dead keratinocytes, revealing a smoother, more luminous surface while stimulating new cell growth. 

Research shared in the Journal of Cosmetics highlights how ingredients like alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) work synergistically: AHAs such as glycolic and lactic acid polish the surface, while BHAs like salicylic acid penetrate deeper to clear pores and improve clarity. 

Over time, this process not only refines texture but also reduces dark spots and uneven pigmentation by promoting the emergence of fresh, evenly toned skin. 

As Healthline explains, exfoliating also enhances the absorption of brightening ingredients, boosts collagen production, and prevents clogged pores, leaving skin brighter, smoother, and more youthful.

Picking or squeezing pimples might seem harmless, but dermatologists warn it can seriously increase your risk of dark spots and hyperpigmentation. 

When you pick at a blemish, you cause extra inflammation and skin trauma, which triggers the skin to produce too much melanin, the pigment that gives your skin its color. 

This overproduction can leave behind dark marks known as post-inflammatory hyperpigmentation (PIH). 

According to findings published in the Journal of Clinical and Aesthetic Dermatology, PIH is especially common in people with darker skin tones, affecting around 65% of African Americans, 52% of Hispanics, and nearly half of Asians after acne. 

Additionally, bacteria and yeast on your hands and under your nails, like Staphylococcus aureus and Pseudomonas aeruginosa, can worsen inflammation and delay healing, increasing the chance of discoloration. 

Dark spots caused by picking may take years to fade, or even become permanent, while untouched blemishes often fade within 3 to 12 months. 

To protect your skin, resist the urge to pick, keep your hands clean, and always wear sunscreen to prevent further darkening.

Maintaining a consistent skincare routine helps prevent dark spots and hyperpigmentation. 

Skipping occasionally won’t ruin progress, but frequent lapses can slow improvement. Gradually introducing new products allows your skin to adapt. Most people see visible results after a few weeks of consistent care.

Eating a balanced diet keeps your skin healthy and helps prevent dark spots. Foods rich in vitamins A, C, D, E, zinc, and omega-3s protect your skin, fight damage, and promote an even tone. 

According to the Journal of Nutrients, including these nutrients in your daily meals can make your skin glow and look youthful.

Red light therapy enhances circulation by stimulating small blood vessels beneath the skin, improving oxygen and nutrient delivery. 

This increased blood flow supports cell repair and renewal, leading to brighter, smoother, and more even-toned skin. Visible improvements often appear within three to six weeks of consistent use.

At Washington Care Clinic, red light therapy is more than a beauty treatment, it’s a science-backed way to restore skin health by naturally boosting collagen. 

Collagen keeps our skin smooth, firm, and youthful, but as Medical News Today notes, its levels decline with age, leading to wrinkles and loss of elasticity. 

Red light therapy stimulates the skin’s cells and mitochondria, encouraging collagen and elastin production while improving circulation for a radiant glow. 

Unlike harsh chemical treatments, it works gently with your body’s healing process, helping reduce fine lines, even out skin tone, and restore firmness, so your skin not only looks younger but feels healthier from within.

Red light therapy accelerates wound and scar healing by stimulating collagen production and improving blood flow. 

This promotes faster tissue formation, reduces inflammation, and helps break down old scar tissue. With consistent use, scars typically become lighter and smoother within four to eight weeks.

Red light therapy reduces skin inflammation by lowering oxidative stress and supporting cellular repair. 

It calms redness and swelling without heat or harsh chemicals, making it suitable for sensitive skin. 

The treatment also helps restore the skin’s barrier to prevent future irritation. Regular use can relieve conditions such as rosacea, eczema, and acne-related inflammation, leading to less redness and smoother, calmer skin within weeks.

Red light therapy improves skin texture and tone by stimulating collagen and elastin production, which keep the skin firm and smooth. 

It promotes cell turnover, helping reduce uneven pigmentation and roughness. With consistent use, the skin becomes smoother, tighter, and more even in tone. 

Noticeable improvements often appear within one to two months, and regular use of home devices can also enhance skin brightness and firmness.

Red light therapy has gained strong scientific backing for its ability to reduce fine lines and wrinkles by boosting collagen production and improving skin elasticity. 

Studies, including one published in Photomedicine and Laser Surgery (2014), showed that participants who received red light therapy twice weekly for 30 sessions experienced noticeable improvements in collagen density and skin smoothness. 

Similarly, research in Lasers in Medical Science (2016) found a 400% increase in collagen synthesis in treated fibroblasts. 

This works because red light activates fibroblast cells, enhances cellular energy (ATP), and increases blood circulation, allowing the skin to repair and renew itself more effectively.

Clinical evaluations, such as one in Skin Research and Technology, reported a 15.6% reduction in crow’s feet depth after just one month of consistent use, with improvements reaching up to 38.3% after three months, along with firmer, smoother skin. 

Compared to retinol or microneedling, red light therapy is non-invasive and gentle while still offering visible anti-aging benefits when used regularly under optimal intensity and duration.

Red light therapy (RLT) is generally considered safe for all skin tones, but its effects can vary depending on melanin levels. Research published in the Journal of Biophotonics found that high-fluence LED red light was well tolerated across all Fitzpatrick skin types, with only mild, temporary effects like redness or hyperpigmentation. The study concluded that RLT is safe up to 320 J/cm² for skin of color and 480 J/cm² for lighter skin, though darker skin may be more photosensitive. People with deeper complexions (types IV–VI) may experience post-inflammatory hyperpigmentation, light or dark patches, or mild sensitivity if high settings are used. According to dermatologists and FDA guidelines, most red light devices are Class II and generally safe for home use when following instructions. While long-term data are still limited, evidence suggests RLT remains a non-invasive, low-risk treatment when used correctly, especially with proper settings, gradual intensity increases, and dermatologist guidance.

Children and teenagers should generally avoid red light therapy for pigmentation concerns due to risks like hyperpigmentation, especially in darker skin tones, uncertain long-term effects on developing skin, and lack of professional oversight. Dermatologist consultation is essential to explore safer, evidence-based alternatives and individualized treatment.

You can combine red light therapy with gentle skincare products. Start with clean skin and use the therapy before applying serums or moisturizers. The light works best on bare skin and can improve product absorption. Avoid strong actives like harsh exfoliants or heavy retinol before treatment to prevent irritation. Use vitamin C or mild retinol later in your routine. For best results, stay consistent, keep your skin hydrated, and use soothing, nourishing products.
