Freckles: Remedies, Causes, and More

Why freckles appear

Freckles are tan or light brown spots on your skin. They’re made of clusters of skin cells that contain the pigment melanin. Unlike moles, which are raised, freckles are flat. Freckles aren’t painful or harmful.

No one is born with freckles, even though they may be genetic. They’re triggered by sun exposure. If you have freckles and want to get rid of them, here are seven ways to consider.

Sunscreen

1. Sunscreen

Sunscreen won’t get rid of existing freckles, but it helps prevent new ones. You should wear sunscreen year-round, even when it’s cloudy.

The American Academy of Dermatology offers these tips:

  • Sunscreen should have an SPF of 30 or higher.
  • Apply sunscreen to bare skin at least 15 minutes before going outdoors.
  • Reapply sunscreen every two hours, and immediately after swimming or excessive sweating.

Laser treatment

2. Laser treatment

Laser treatment uses pulses of focused, intense light to target damaged areas of skin. There are different types of lasers. According to a 2015 study, the 1064 Q-Switched Nd YAG laser is effective for treating freckles. Study results showed treatment with this laser lightened more than 50 percent of freckles in 62 percent of participants.

Laser treatment is generally safe. The risk of scarring is low. However, other side effects may occur, including:

  • itching
  • swelling
  • redness
  • crustiness
  • peeling
  • infection
  • changes in skin color

If you have a history of oral herpes, you may need to take an antiviral medication before undergoing laser treatment. That’s because the laser can stimulate a flare-up of herpes around your mouth.

Your healthcare provider may prescribe other medications or creams before the procedure. They may also recommend avoiding certain medications or products before the procedure. Let your doctor know about any medications or creams you’re using.

It may take up to two weeks to recover from laser treatment. Multiple sessions are usually needed to achieve desired results.

Cryosurgery

3. Cryosurgery

Cryosurgery uses extreme cold in the form of liquid nitrogen to freeze and destroy abnormal skin cells. Cryosurgery is generally safe, and it requires no anesthesia and little recovery time. Some potential side effects are hypopigmentation, bleeding, and blistering. Cryosurgery rarely causes scarring.

Fading cream

4. Topical fading cream

Fading cream, also called bleaching cream, is available both over the counter and by prescription. Many fading creams contain hydroquinone, an ingredient thought to suppress melanin production and lighten darkened areas of skin.

Topical hydroquinone cream may cause:

  • inflammation
  • dryness
  • burning
  • blistering
  • skin discoloration

In 1982, the U.S. Food and Drug Administration (FDA) considered bleaching products that contained up to 2 percent hydroquinone as generally safe and effective. In 2006, new evidence indicated hydroquinone may cause cancer in rats and result in skin darkening and disfiguration. This led the FDA to nominate hydroquinone for further study under the National Toxicology Program (NTP). Even so, the FDA recommended hydroquinone products stay on the market until the NTP’s research is complete.

Retinoid cream

5. Topical retinoid cream

Retinoid cream is a vitamin A compound. It’s used to improve sun-damaged skin and lighten freckles. According to a 2014 review, retinoids may offer photoprotection by absorbing ultraviolet B radiation. This may help prevent new freckles from forming.

Retinoid creams are available with or without a prescription. Common side effects are:

  • redness
  • dryness
  • skin irritation
  • peeling
  • sensitivity

Chemical peel

6. Chemical peel

A chemical peel uses a chemical solution to exfoliate and peel off areas of damaged skin. To remove freckles, a moderate skin peel containing glycolic acid or trichloroacetic acid penetrates the skin’s middle layers. Once damaged skin is removed, new skin is generated.

Chemical peels may temporarily cause:

  • stinging
  • peeling
  • redness
  • irritation
  • crusting
  • swelling

According to the American Society for Dermatologic Surgery, moderate skin peels take up to two weeks to heal. You’ll need to soak your skin daily and apply topical ointment. You’ll also need to take a prescription antiviral for up to two weeks, and avoid the sun until your skin has healed.

Natural remedies

7. Natural remedies

There are several natural remedies people swear by to get rid of freckles. None are scientifically proven. Still, most are unlikely to cause harm when used in moderation.

These natural remedies include:

Lemon juice: Apply lemon juice directly to your skin with a cotton ball, and then wash it off. Lemon juice is thought to lighten skin.

Honey: Combine honey with salt or sugar to make a scrub. Honey may help lighten pigmentation.

Buttermilk: Apply buttermilk directly to your skin. You should leave it on for 10 minutes before rinsing it off with warm water. You can also create a mask by combining buttermilk with oatmeal. Buttermilk has lactic acid, which could potentially help lighten your freckles.

Sour cream: Apply sour cream directly to your skin, and then wash it off after a few minutes. Like buttermilk, sour cream contains lactic acid.

Yogurt: Apply yogurt directly to your skin and leave it on for a few minutes. Yogurt also contains lactic acid.

Onion: Rub the onion over your skin, and then rinse your skin in warm water. Onion can act as an exfoliate and may help lighten spots.

If you experience any irritation, stop using the remedy.

Causes

What causes freckles

Your skin contains cells called melanocytes that produce the pigment melanin. Melanin helps protect your skin from the sun’s ultraviolet rays. Sun exposure encourages melanocytes to produce more melanin. Freckles are a build-up of melanin on your skin’s outer layer.

Most people with large numbers of freckles have fair skin, although anyone can get them. Even though fair-skinned people normally produce less melanin than those with darker skin, their melanocytes produce more melanin during sun exposure.

No treatment

Freckles may go away on their own

Some freckles are in it for the long haul. Others are most prominent in the summer due to increased sun exposure, but will fade during winter or by avoiding direct sunlight. Freckles that are hereditary may diminish as you age. Freckles caused by sun damage tend to increase with age.

See a doctor

When to see a doctor

Freckles are noncancerous, but they may be confused with skin cancer. Excessive sun exposure is a risk factor for both freckles and melanomas. Melanoma is more common in people with fair skin or freckles than in those with dark skin.

If you notice changes in size, color, or shape of a freckle, see your doctor or dermatologist. They’ll be able to determine whether it’s a reason for concern.

Takeaway

The bottom line

Freckles are common and benign, yet many people want to get rid of them for cosmetic reasons. Invasive remedies such as laser therapy and chemical peels are effective, but require extensive healing time and may cause serious side effects.

If you want to send your freckles packing, talk to your dermatologist to determine the best removal method for you. No matter what method you choose, it’s important to practice safe sun care afterward to help prevent new freckles.
