Sunspots on Skin: Causes and Treatment

Sunspots and treatment

What are Sunspots?

Sunspots, also called solar lentigines, are areas of increased pigmentation that appear on skin exposed to the sun. They develop when the skin is damaged by ultraviolet (UV) radiation from the sun or tanning beds. Sunspots typically appear as tan, brown, or black spots or patches on areas frequently exposed to sunlight like the face, hands, arms, chest, and shoulders.

Sunspots are more common in people with lighter skin, but those with darker complexions can develop them as well. They tend to appear more frequently with age as skin is exposed to UV radiation over time. The melanocytes, cells that produce melanin pigment, become damaged and produce excess melanin that results in darker spots on the skin. Sunspots range in size from less than a centimeter to several centimeters wide. Some people may develop just one sunspot, while others can have 10 or more at a time.

Causes of Sunspots

Sunspots, also called solar lentigines, are dark spots that appear on skin exposed to the sun. They are caused by increased production of melanin, which is the pigment that gives skin its color. There are several factors that contribute to sunspot development:

  • UV Exposure – Ultraviolet rays from sunlight are the main cause of sunspots. UV exposure over time damages skin cells called melanocytes, which produce melanin. This causes them to become overactive, producing more melanin in concentrated areas which show up as dark spots. Areas of skin that get frequent sun exposure like the face, hands, arms and chest are most prone to sunspots.

  • Aging – As skin ages and loses elasticity, it is more susceptible to sun-related skin damage. Sunspots are more common in adults over age 40 as the cumulative effects of UV radiation take their toll on skin over time. The skin’s ability to repair sun damage slows down with age.

  • Genetics – Some people are just genetically prone to developing sunspots because they inherit skin that tans easily. People with fairer skin tend to get more sunspots because they have less protective melanin overall compared to those with darker complexions.

  • Skin Type – Fair skin that freckles or burns easily is at highest risk for sun damage and sunspots. Those with olive or darker skin tones have more melanin naturally and are less susceptible to sunspots. But no skin color is immune.

Sunspot Symptoms

Sunspots typically appear as flat, brown to black patches on areas of skin that get frequent sun exposure. They are most commonly found on the face, hands, arms, chest, and other body parts that are often left uncovered.

Sunspots can range in size considerably. Some are small and freckle-like, while others can grow to be larger than a coin. Their color also varies from light tan to very dark brown or black.

The spots are not harmful, but many people find them to be cosmetically unappealing. Sunspots tend to be more noticeable on lighter skin tones, as they strongly contrast with the surrounding skin. Those with fair complexions are especially prone to developing sunspots from sun exposure over time.

While sunspots themselves do not cause any pain or irritation, their presence can be indicative of UV damage to the skin. It’s important to take precautions against further sun exposure to prevent existing sunspots from growing and new ones from forming. Using sunscreen, covering up, and avoiding peak sun hours are key to protecting the skin.

Sunspot Treatment and Removal

There are several treatment options available for removing sunspots and restoring an even skin tone. Some of the most common and effective approaches include:

Prescription Creams

Dermatologists may prescribe creams that contain retinoids (like tretinoin) or bleaching agents (like hydroquinone). These ingredients help fade sunspots by speeding up skin cell turnover and inhibiting melanin production. It may take several months of daily use to see results.


Liquid nitrogen is applied directly to sunspots to freeze and destroy the excess pigment. The spots will later peel off as the skin regenerates. Multiple sessions are usually needed for optimal results.

Laser Therapy

Lasers send focused light energy to the affected areas to break up the pigment. Common options are fractional CO2 lasers and Q-switched lasers. Several treatments spaced weeks apart are required for success. Mild pain, redness and peeling may occur.

Dermabrasion and Chemical Peels

Dermabrasion uses a wand to gently “sand” off the top layers of skin. Chemical peels apply a solution like glycolic acid to exfoliate the skin. Both remove sun-damaged areas and promote new collagen growth. Some downtime is required for healing.

Sun Protection

Preventing new sunspots is crucial. Diligent sunscreen use, protective clothing, hats, and seeking shade are essential. Daily application of a broad-spectrum, SPF 30 (or higher) sunscreen can help minimize additional sun damage.

Preventing Sunspots

Sunspots can often be prevented by taking some simple precautions when spending time in the sun:

  • Wear sunscreen with an SPF of at least 30. Apply liberally and reapply every 2 hours when outdoors. Sunscreen protects skin from UV damage that causes sunspots.

  • Wear protective clothing like hats, sunglasses, and tightly-woven fabrics that cover arms and legs. This creates a physical barrier between your skin and the sun’s rays.

  • Avoid being outdoors during peak sun hours between 10am-2pm when UV rays are strongest. Plan outdoor activities in early morning or late afternoon.

  • Eat foods high in antioxidants like berries, leafy greens, tomatoes, and citrus fruits. Antioxidants help neutralize skin damage from UV exposure. Consider taking vitamin C supplements as well.

  • Use skin brightening creams with ingredients like hydroquinone, kojic acid, licorice extract, and niacinamide. These can help fade existing sunspots and block enzymes that lead to excess melanin production.

  • See a dermatologist at the first sign of sunspots. They can prescribe creams to lighten sunspots, or use laser therapy and cryotherapy to remove spots.

The key is vigilance – inspect your skin often, and be proactive to minimize sun exposure and UV damage. With some simple precautions, you can help prevent the development of sunspots.

Areton Activated Charcoal Soap Benefits

One of the most effective ingredients for fading sunspots and improving skin discoloration is activated charcoal. Areton’s activated charcoal soap bar contains a high concentration of this powerful ingredient.

When activated charcoal is applied topically, it provides several benefits:

  • Draws out impurities from skin – The porous structure of charcoal acts like a magnet to bind to dirt, oil, and other impurities that have accumulated in pores. This helps pull these impurities to the surface so they can be washed away.

  • Exfoliates dead skin cells – In addition to drawing out impurities, charcoal also exfoliates the top layer of dead skin cells. This reveals the newer, healthier skin underneath. Exfoliation helps fade sunspots by removing the damaged pigmented cells.

  • Helps fade sunspots and improve skin tone – By clearing away impurities and promoting cellular turnover, activated charcoal evens out skin discoloration and reduces the appearance of sunspots and age spots. It helps restore a brighter, more youthful complexion.

  • Antibacterial properties – Charcoal contains antibacterial compounds that destroy acne-causing bacteria on the skin. This helps prevent breakouts.

With regular use, Areton’s activated charcoal soap bar can significantly lighten sunspots while also improving overall skin health and radiance. The charcoal works with the skin, not against it, to gently cleanse and refresh.

Salicylic Acid Scrub Soap Benefits

Salicylic acid is a beta hydroxy acid that can help improve the appearance of sunspots and skin clarity in several ways. It works as a gentle exfoliant that removes dead skin cells from the surface of the skin. This helps reveal newer, healthier looking skin underneath.

The exfoliating properties of salicylic acid also help treat sunspots and age spots by accelerating skin cell turnover. This helps fade discoloration faster.

In addition, salicylic acid is an effective acne treatment. It can penetrate deep into pores to remove oil, bacteria, and dead skin cells that cause breakouts. By preventing clogged pores, it helps reduce future acne outbreaks and improves overall skin texture.

The scrub particles in the soap provide physical exfoliation to complement the chemical exfoliation of the salicylic acid. This combination helps thoroughly but gently scrub away dull surface skin cells, dirt, and oil to visibly brighten and refresh the complexion.

Regular use of a salicylic acid scrub soap can help minimize the appearance of sunspots while keeping skin clear and smooth. The deep exfoliation reveals fresher, younger looking skin by treating acne, reducing discoloration, and improving texture.

Kojic Acid Benefits

Kojic acid soap is an effective treatment for sunspots and other forms of hyperpigmentation and uneven skin tone. The key ingredient, kojic acid, is a natural skin brightener derived from mushrooms that helps lighten sunspots, age spots, melasma, and other darkened areas on the skin.

Kojic acid works by inhibiting tyrosinase, an enzyme involved in melanin production. By slowing down melanin synthesis, kojic acid reduces excess pigmentation and reveals brighter, more even-toned skin. It helps fade sunspots and age spots gradually over time with regular use.

In addition to its skin lightening abilities, kojic acid soap offers powerful anti-aging benefits by reducing the visible signs of aging like wrinkles, fine lines, and sagging skin. Its antioxidants protect the skin from free radical damage that can lead to premature aging. With its skin renewal and exfoliating properties, kojic acid retexturizes the skin for a youthful glow.

Overall, kojic acid soap helps even out skin tone, erase sunspots and age spots, reduce hyperpigmentation, and restore a bright, healthy complexion. When used consistently, it can diminish the appearance of sunspots and reveal luminous, more uniform skin.

Aloe Vera Benefits

Aloe vera is known for its soothing and healing properties, making it an ideal ingredient for sunspot-prone skin. The aloe plant is rich in antioxidants, enzymes, vitamins A, C, and E, and minerals that help repair skin damage from the sun.

When used in soap, aloe vera provides the following benefits:

  • Soothes Damaged Skin: The natural enzymes and polysaccharides in aloe vera have anti-inflammatory effects that calm irritation and redness from sun exposure. Aloe is very gentle and won’t dry out sensitive skin.

  • Hydrates and Moisturizes: Aloe vera increases moisture content in the outer layer of skin and prevents water loss. Its humectant properties allow it to attract and retain moisture in the skin. This helps improve the appearance of sunspots which can look more pronounced on dry skin.

  • Fades Sunspots: Research shows aloe vera inhibits tyrosinase, the enzyme involved in melanin production. This helps lighten sunspots and areas of hyperpigmentation. With regular use, aloe soap can help fade and even out skin tone.

  • Rich in Antioxidants: Aloe contains antioxidants like vitamin C and E, beta carotene and polyphenols that neutralize free radicals and protect skin from further UV damage. This helps prevent new sunspots from forming with continued use.

With its blend of skin-nourishing ingredients, aloe vera soap is an ideal way to care for sun-damaged skin prone to sunspots and hyperpigmentation. Its soothing, anti-inflammatory properties also provide relief from sunburns.

Sulphur Benefits

Sulphur has been used for centuries to treat various skin conditions thanks to its natural antiseptic and exfoliating properties. Sulphur contains keratolytic effects that help break down the structure of dead skin cells, clearing pores, and allowing new cell growth. This makes it effective at treating acne and other inflammatory skin issues.

The antimicrobial effects of sulphur also help kill bacteria on the skin that can contribute to acne breakouts. By reducing excess oil and drying out the skin, sulphur soap can help prevent new blemishes from forming. Many users struggling with persistent acne find that sulphur soap helps dry out and disinfect oily, acne-prone areas.

In addition to its antibacterial effects, sulphur also acts as a mild exfoliant. Its keratolytic action works to slough off dead skin cells and smooth areas of rough texture. This unveils fresh new skin underneath and improves skin radiance and glow. The exfoliating effects also help keep pores clear of blockages that can lead to whiteheads and blackheads.

With its multi-action benefits of exfoliating, disinfecting, and drying out excess oil, sulphur soap is an effective option for those struggling with breakouts, body acne, oily skin, or clogged pores. It offers a deep cleanse while also treating and preventing future blemishes.
