Freckles vs Sunspots: How Can You Tell the Difference?

Freckles and sunspots are both common forms of skin pigmentation that can, at first glance, seem very similar. They’re both associated with sun exposure and the production of melanin, the pigment that makes your skin glow and darken as you tan. However, there are key differences between sunspots vs freckles, in both their appearance and what causes them.

Read on to uncover the mystery of freckles vs sunspots and ways to deal with unwanted pigmentation.

What are Freckles?

Freckles are small patches of concentrated melanin that appear as tiny brown dots after you’ve been in the sun. They usually appear on the face but also sometimes on the shoulders, arms, and other areas of the body. Their appearance depends on the person’s skin tone; the darker the skin tone, the less obvious freckles may be.

Common characteristics of freckles include uniform coloration and small size. Freckles are largely influenced by genetics and appear as a natural response to UV exposure. Most people notice that their freckles appear in similar patterns every time, although they may be more pronounced after spending longer in the sun.

What are Sunspots?

Sunspots are also areas of darker skin that are caused by UV exposure. Unlike freckles, though, sunspots are not genetic and develop due to a combination of cumulative sun exposure and may be more common as you get older.[i]

They tend to be larger, flat, and well-defined areas of pigmentation. They’re typically much larger than freckles, measuring up to around two centimeters in diameter.

Sunspots are commonly found on the face, shoulders, back, arms, and hands. In other words, areas that are commonly exposed to the sun.

Sunspots vs Freckles: What Are the Key Differences? 

The key difference between freckles vs sunspots:

• Size: Freckles are very small, often 1 mm across; sunspots can be larger, up to 2 cm across

• Cause: Freckles occur in people who are genetically predisposed to developing them; anyone can develop sunspots

• Age: Freckles can appear in very young children; sunspots are more common as you get older

Are Freckles or Sunspots Harmful?

Freckles and sunspots are generally both completely harmless forms of skin pigmentation. However, some people may feel self-conscious if they develop sunspots on their face.

As always, if an area of skin suddenly changes color, size, or texture, see a doctor as soon as possible.

How to Treat and Help Prevent Sunspots 

While sunspots rarely fully disappear, they may gradually fade if you reduce your UV exposure for an extended period of time. The best approach is sunspot prevention, via consistent sun protection habits.

The benefits of sunscreen include helping to protect you from unsightly sunspots. Broad-spectrum sunscreen protects against both UVA and UVB rays, both of which may contribute to the visible signs of sun damage and premature skin aging.

Incorporating SPF skincare into your daily routine is one of the simplest ways to help protect your skin from sun-induced pigmentation and support a healthy-looking, radiant complexion.  

FAQ

Do sunspots go away? 

Most sunspots won’t fully vanish on their own, although they may fade over time. Some people choose to have specialist treatments to reduce the appearance of sunspots. Making sunscreen part of your daily skincare routine is a simpler way to prevent sunspots.

Can you reverse sunspots?

You may find that sunspots fade if you stay out of the sun for a long time. Unfortunately, they will often darken again once your skin is re-exposed to the sun, especially if you forget to apply sunscreen.

Can freckles turn into sunspots? 

No, freckles are small dot-like pigmentations caused by genetics, while sunspots develop over time due to repeated sun exposure. You may develop sunspots alongside freckles, but the freckles themselves will remain freckles.
