I remember a patient, let’s call her Sarah, coming into the clinic one sunny afternoon. She’d just had a wonderful week at the beach and, pointing to a fresh sprinkle of tiny brown spots across her nose and shoulders, she asked, “Doctor, where did all these new freckles come from, and are they okay?” It’s a question I hear quite a bit, especially as the seasons, or our sun exposure, changes. So, let’s chat about those little spots.
Understanding Your Freckles: The Basics
So, what exactly are these little spots? Well, freckles pop up when your skin makes a bit extra of something called melanin. Think of melanin as your body’s natural sunscreen; it’s the pigment that gives your skin, hair, and eyes their unique color. It’s produced by special skin cells we call melanocytes.
When your skin meets the sun’s ultraviolet (UV) rays, these melanocytes get to work, producing more melanin to try and protect your skin from damage. If you have a lighter complexion, your melanocytes might kick into high gear, leading to freckles instead of an even tan. It’s just how your skin responds! They’re super common and, importantly, they aren’t a health threat. You might notice them more in the summer months.
While folks with lighter skin and blonde or red hair are often more prone to them, anyone can get freckles. On darker skin, they simply appear as darker brown spots.
Are There Different Kinds of Freckles?
Yep, there are actually two main types of freckles we see: ephelides and solar lentigines.
- Ephelides: These are the classic freckles many of us picture – flat, small, and usually red or tan-to-brown. Sun exposure, and sometimes sunburns, are the main culprits here. You’ll typically find them on sun-exposed areas like your face, arms, upper chest, neck, and back. They often first appear when kids are out playing in the sun and can continue to develop into young adulthood. Interestingly, these ephelides often fade a bit as we get older or when we’re out of the sun for a while. People with lighter skin tones and those of Asian descent tend to see these more often.
- Solar Lentigines: You might know these better as age spots or liver spots. These are generally flat patches that can be yellow, red, brown, or even dark brown. They usually show up in adults, typically over 40, and are a result of repeated sun exposure over many years. Common spots include the face, forearms, the backs of your hands, chest, back, shoulders, and lower legs. Unlike ephelides, these don’t tend to fade in the winter.
It’s easy to get them mixed up, but the biggest clue is often when they appeared and how they behave with sun exposure.
What Makes Freckles Appear?
The number one reason freckles show up? Exposure to ultraviolet (UV) radiation from the sun. But there are a couple of other things that can play a role:
- Genetics: Your genes have a say in whether you’re likely to freckle. If your parents freckled, there’s a good chance you might too!
- Xeroderma Pigmentosum: This is a very rare genetic condition where your skin is incredibly sensitive to UV light. People with this condition will develop freckles and other skin changes very easily.
Do Freckles Need Treatment?
Honestly, since freckles are almost always harmless, there’s usually no medical need to treat them. The most important thing, really, is to be sun smart. If you freckle easily, or if you’d rather not develop more, being diligent about sun protection is key. We’ll talk more about that in a moment.
Thinking About Fading Your Freckles?
If you’re not a fan of your freckles or they’re making you a bit self-conscious, there are a few things we can chat about in the clinic to help lighten them. It’s good to know they can’t be completely removed, but these options can make them less noticeable:
- Acid and Chemical Peels: Products with ingredients like alpha hydroxy acid (AHA), trichloroacetic acid (TCA), glycolic acid, or phenol can help. These work by gently removing the top layer of skin cells, encouraging new, less pigmented skin to come through.
- Retinoids and Retinols: These are forms of Vitamin A that encourage your skin cells to turn over more quickly and can also boost collagen. You might have seen them in anti-aging products.
- Laser Treatments: Certain lasers can target the pigment in freckles and remove the top layer of skin.
- Cryotherapy: This is a procedure where a very cold substance, usually liquid nitrogen, is used to freeze the spots. The treated areas then darken and shed after a few days. This is often used for solar lentigines.
If you’re considering any of these, it’s best to talk to a dermatologist. They can look at your skin and help you decide what might be the safest and most effective approach for you.
How Can I Keep New Freckles From Showing Up?
Since sun exposure is the main driver for freckles, protecting your skin from sunlight is your best bet for prevention:
- Sunscreen, Sunscreen, Sunscreen! I can’t say this enough. Always apply a broad-spectrum sunscreen (meaning it protects against UVA and UVB rays) with an SPF of 30 or higher. Make sure it’s water-resistant. Put it on all exposed skin before you head outside, every single day – yes, even on cloudy days and in winter! Reapply every two hours, or more often if you’re swimming or sweating a lot.
- Cover Up: Wear a wide-brimmed hat, sunglasses that offer UV protection, and lightweight long-sleeved shirts and pants when you’re out in the sun. Look for clothing with an ultraviolet protection factor (UPF) label for even better protection.
- Time it Right: Try to avoid being in direct sun during the peak UV hours, which are usually between 10:00 a.m. and 4:00 p.m.
- Skip the Tan: Avoid tanning beds and try not to deliberately sunbathe. If you like a tanned look, a spray-on tanning product is a much safer option.
Freckles vs. Moles: What’s the Difference?
This is a common point of confusion! Moles can pop up anywhere on your body and come in all sorts of shapes and sizes – they’re usually a bit larger than freckles. They can be pink, tan, blue, black, or even skin-toned or colorless. Moles can be flat or slightly raised.
Most moles are perfectly harmless (benign). However, they can sometimes change in size, shape, or color, and a small number can turn into skin cancer. Moles often appear in childhood and through the first 20 years of life, though some can show up later. Most of us have at least a few.
The moles we pay closer attention to are those that look different from your other moles, or any that first appear after you’re 20. While most don’t need treatment, if you notice any changes in a mole’s color, height, size, or shape, it’s definitely worth getting it checked by a dermatologist.
A Word on Melanoma
Melanoma is the most serious type of skin cancer. It can grow quickly and has the potential to spread. Most melanomas are black or brown, but they can sometimes be pink, red, purple, or even skin-colored. About 30% of melanomas start in existing moles, but the majority actually begin in what looks like normal skin. This is why paying attention to any new or changing spots on your skin is so important.
Checking Your Skin: The ABCDEs of Freckles and Moles
Knowing your ABCDEs is a really helpful way to keep an eye on your skin spots, whether they’re freckles or moles. The American Academy of Dermatology and the American Cancer Society recommend looking for:
- A is for Asymmetry: If you drew an imaginary line down the middle of the spot, the two halves wouldn’t match.
- B is for Border: The edges are irregular, ragged, notched, or blurred.
- C is for Color: The color isn’t the same all over. It might have shades of black, brown, or tan, or even patches of red, white, blue, or pink.
- D is for Diameter: The spot is larger than about 1/4 inch across (roughly the size of a pencil eraser).
- E is for Evolving: The spot has changed in size, shape, or color.
If you notice any of these signs, please make an appointment to see your doctor or a dermatologist. Don’t wait. Also, it’s good to know that some worrisome spots don’t follow these rules perfectly. Other warning signs can include:
- A new spot or growth that looks different from your other spots.
- A sore that just won’t heal.
- Redness or swelling that spreads beyond the border of the spot.
- Color from the spot spreading into the surrounding skin.
- A spot that starts to itch, feel painful, or tender.
- Changes to the surface of the spot – like oozing, bleeding, scaling, or developing a lump or bump.
What About That Freckle on My Lip?
Freckles can appear pretty much anywhere the sun shines, and that includes your lips! The skin on your lips is still skin, after all. In most cases, a freckle on your lip is just like any other freckle – harmless. But, just like with any skin spot, keep an eye on it. If you see any changes, it’s best to have a dermatologist take a look.
Sometimes, a spot on the lip might look like a freckle but could be a mole or even related to a rare condition called Peutz-Jeghers syndrome, which can cause dark spots on the lips and other areas. So, if it’s new or changing, better safe than sorry.
And Those White Freckles I’ve Noticed?
Ah, yes! Sometimes people notice small, flat white spots, especially on their arms and legs. These are often something called idiopathic guttate hypomelanosis. It’s a bit of a mouthful, I know! We think they’re related to long-term sun exposure. Like other freckles, they’re more common in fair-skinned folks but can also show up in older individuals with darker skin.
These white spots happen because there’s a decrease in melanin in those little areas. The good news is, they’re not harmful. If they bother you, there are some treatments like topical steroids, tretinoin (a retinoid), or dermabrasion that might help, but often, no treatment is needed.
When Should I Pop In to See a Dermatologist?
It’s always a good idea to see your doctor or a dermatologist if you notice any of your freckles or other skin spots:
- Changing in size, shape, or color.
- Developing a border that’s jagged, irregular, or not clearly defined.
- Looking asymmetrical (one half doesn’t match the other).
- Becoming sore, itchy, or starting to bleed.
- Becoming raised up from your skin.
- Having very dark areas or multiple colors within the one spot.
Basically, if anything looks new, different, or just plain odd to you, get it checked. Peace of mind is priceless.
