Moles (medically known as naevi) are common skin growths made up of melanocytes (pigment-producing cells) clustered together. They can be flat or raised, and range in color from your natural skin tone to brown or black. Almost everyone has a few moles – most adults have between 10 and 40 moles by adulthoodmy.clevelandclinic.org. These usually first appear in childhood or the teen years, and new moles may continue to emerge into one’s 30s. Over many years, a normal mole may change slowly – for example, it might become slightly raised or lighter – and some may even fade away later in lifemy.clevelandclinic.org. Importantly, the vast majority of moles are benign (non-cancerous) and remain harmless throughout lifemy.clevelandclinic.org. Having moles is normal, but it’s still wise to be familiar with them and monitor any changes over time.
Moles vary in size and appearance. “Common” moles are usually small (under 6mm), evenly colored (tan, brown, or black), round or oval, and have a well-defined border. Some may grow a hair. Certain moles are present at birth (congenital moles) and can be larger; these are still often harmless, though very large congenital moles carry a higher risk of problems later. There are also atypical moles (dysplastic naevi), which look irregular – they may be larger than a pencil eraser, with uneven color and an indistinct border. Atypical moles are still benign, but having many atypical moles can increase the risk of skin cancer, so they merit closer observationdermatologynorthsydney.com.au. In general, however, if a mole has the typical “normal” features and has not changed over time, it can be considered a harmless mole.
Why do moles form? In most cases, moles occur simply due to a combination of genetics and normal skin development. You may notice that moles “run in families” – your genetic makeup influences how many moles you have and what they look likeclearcreekdermatology.com. Some people naturally have more moles than others.
Beyond genetics, a few key factors can contribute to the development of new moles or changes in moles:
Bottom line: Most harmless moles are caused by normal clustering of pigment cells influenced by your genes, and they often appear early in life. Sun exposure can increase the number of moles you get, and hormonal phases can bring about new moles or slight changes in them. Having fair skin or a large number of moles increases the need for careful monitoring (since these factors correlate with higher skin cancer risk). The next section will outline what to watch for, even though the typical mole is not dangerous.
Because moles are so common, it’s important to know which changes might indicate a problem. A harmless mole, by definition, stays relatively stable in size, shape, and color over time. However, melanoma, the most serious form of skin cancer, can sometimes develop in or near a mole. It’s uncommon, but catching it early is critical. So, as a patient, you should be aware of the warning signs that a mole may need medical evaluation.
Dermatologists often teach patients the “ABCDE” criteria as a simple guide for suspicious features in a moleclearcreekdermatology.com:
In addition to the ABCDEs, pay attention to symptoms. A mole that itches, bleeds, ulcerates (forms a sore), or becomes tender for no apparent reason warrants a prompt medical exammy.clevelandclinic.org. These symptoms are not typical of a harmless mole. Also, watch for any mole that repeatedly scabs or refuses to heal, as this is abnormal.
Another tip: most people’s benign moles look somewhat similar to each other – so if one lesion stands out as different (the “ugly duckling”), have it examined. And as mentioned earlier, new moles develop less commonly after about age 30. If you’re an adult and notice a brand-new mole in your 30s or beyond, it’s likely still harmless, but it’s a good idea to have a doctor take a lookmy.clevelandclinic.org.
When in doubt, check it out. You don’t need to run to the doctor for every tiny spot, but you should err on the side of caution if a mole displays any of the above red flags. Dermatologists have special tools (like dermatoscopes) to examine moles more closely and can perform a biopsy (removing a small sample or the whole mole) if needed to determine if it’s benign or malignant. Early evaluation and detection is the key to managing any potential skin cancer effectively.
High-risk individuals (for example, those with 50 or more moles, a personal or family history of skin cancer, or very atypical moles) should consider regular full skin exams with a dermatologistaad.org. But even for everyone else, it’s wise to do monthly self-skin checks at home – use a mirror or ask someone to help check hard-to-see areas like your back. By being familiar with your own moles, you’ll be more likely to notice if any one of them starts to change or stand out.
For most harmless moles, no medical treatment is necessary. If a mole is benign and not causing you any trouble, you can simply leave it alone. Many people choose to keep their moles and just monitor them. In fact, doing nothing is often the safest and simplest approach for normal moles. Remember that removing a mole will generally leave some form of scar, so the benefit should outweigh that downside.
That said, there are a few common reasons why you might opt to remove a benign mole:
If you and your doctor decide that a mole should be removed, there are several treatment methods available. The choice of method depends on factors like the mole’s size, depth, and location, as well as whether a biopsy is needed. Below is an overview of the main mole removal techniques:
(Other methods: In some practices, electrocautery or radiofrequency ablation can be used similarly to shave excision – basically burning off the mole at the surface after numbing. These achieve a result similar to laser or shave removal. Chemical mole removal is not an established medical practice, though there are caustic acids that can destroy tissue – these should be avoided outside a physician’s guidance.)
Important: Always have a qualified practitioner evaluate your moles before removal. This ensures that the appropriate method is chosen and, most critically, that a suspicious mole isn’t inappropriately treated with a non-surgical method. A dermatologist will determine if a mole is safe to remove via laser or other means, or if it should be cut out and tested. Never hesitate to ask if a removed mole will be sent to pathology – for any uncertainty, a biopsy is the golden rule.
We’ve highlighted laser removal as an option for harmless moles – here we’ll expand on how it works and why we use it. At our clinic, we are proud to utilize the Fotona SP Dynamis Pro laser system for mole removal. This is a state-of-the-art medical laser platform that actually contains two complementary laser wavelengths in one deviceclarionmedical.com. In simple terms, one laser (Nd:YAG) penetrates into the deeper layers of skin, and the other laser (Er:YAG) precisely targets the surface. By combining these, the Fotona SP Dynamis can treat a wide range of skin concerns with great precisionclarionmedical.com. For mole removal, we primarily use the laser in a way that ablates (vaporizes) the mole tissue layer by layer. The Er:YAG wavelength is excellent for gently “brushing away” surface imperfections like moles, with very fine control and minimal heat damage to surrounding skinclarionmedical.com. This means we can remove the visible mole while keeping the adjacent skin as untouched as possible, which promotes better cosmetic healing.
What to expect with laser removal: If a mole is suitable for laser therapy, the area will be cleansed and you’ll wear protective eyewear. The treatment usually takes only a few minutes for a single mole. You may feel a warm or slight tingling sensation as the laser pulses on the mole – patients often compare it to a small rubber band snap or a hot pinch, but it’s quite tolerable. (If needed, a numbing cream or local anesthetic can be used, though many times it’s not necessary.) After laser treatment, the mole will darken or form a scab/crust over the next several days as the unwanted tissue is broken down. This crust will flake off on its own within 1–2 weeks, revealing new skin underneath. It’s important not to pick at it during healing. We advise keeping the site clean, dry, and protected with a bit of ointment as directed. Also, avoid sun exposure on the treated spot while it heals (cover with clothing or at least SPF 30 sunscreen) to ensure the new skin doesn’t hyperpigment.
As mentioned, one advantage of laser removal is the typically minimal scarring. Lasers can precisely target the mole’s pigment, often resulting in less collateral injury than cutting might causecoastalskinandlaser.com.au. In many cases, after a few months, the laser-treated site is barely noticeable – perhaps a faint spot slightly lighter or pinker than surrounding skin, which usually fades over time. That said, everyone heals differently. A small risk of a mild scar or temporary color change exists with any method, including lasers. We will give you aftercare instructions to help optimize the healing (for instance, applying vaseline or a scar gel once the area has closed, and sun protection as noted). Overall, cosmetic outcomes with laser are excellent for benign moles in appropriate candidates.
Limitations of laser: We reiterate that laser mole removal is only done for moles that have been assessed as benign. Any mole with suspicious features should be surgically excised instead, so that a pathology exam can confirm the diagnosiscoastalskinandlaser.com.au. Our priority is your health, so we will not laser anything that we think might need a biopsy. Additionally, very large or very deep moles might not clear completely with a single laser session. In some cases, we perform a second treatment after a number of weeks if residual pigment remains (we tailor this to the individual; our goal is complete removal with the best cosmetic outcome, even if it occasionally takes two sessions)dermatologynorthsydney.com.au. We will discuss with you beforehand if we anticipate multiple sessions. Another consideration is mole recurrence: because lasers break up the mole cells rather than cutting them all out, there is a small chance a mole could partially regrow (if some melanocyte cells were left behind). This doesn’t happen often, but if it does, we can evaluate the area and possibly treat it again or opt for excision. Regular skin check-ups remain important even after cosmetic mole removal.
In summary, laser treatment offers a modern, quick, and tissue-sparing way to remove unwanted benign moles. It’s especially useful for cosmetic removals on the face or other visible areas where minimizing scarring is paramountcoastalskinandlaser.com.au. Our clinic’s use of the advanced Fotona SP Dynamis Pro system means you’re getting one of the best technologies available, operated by experienced professionals who prioritize safety. If you have a mole of concern cosmetically, and it’s a good candidate for laser, we’ll be happy to discuss this option with you.
In addition to laser treatments, we also offer LED light therapy as part of our skincare arsenal. LED (Light Emitting Diode) therapy is a gentle, non-invasive treatment that can improve overall skin condition and assist in the healing process after procedures like mole removal. Unlike lasers, LED devices do not heat or ablate the tissue; instead, they shine specific wavelengths of light that penetrate the skin and stimulate cells in various waysmolechex.com.au. This therapy is sometimes called low-level light therapy (LLLT) or photobiomodulation. It has become a popular adjunct treatment for rejuvenating the skin, reducing inflammation, and speeding recovery.
How LED light therapy works: Different colors (wavelengths) of LED light have different benefits for the skinmolechex.com.au:
Often, LED devices combine a couple of these colors or cycle through them, depending on the skin concerns being addressed. A typical LED phototherapy session involves sitting or lying under an array of lights or wearing an LED mask for about 15-20 minutes. It’s painless – you just feel a warm light – and requires no downtime at all. We frequently include an LED session after procedures (like after laser mole removal or other laser treatments) because it can reduce post-treatment redness and inflammation, and potentially speed up the skin’s recovery.
Is LED therapy safe? Yes, very. LED treatments are non-thermal (no heat damage) and do not use UV light, so they do not carry the risks associated with UV exposuremolechex.com.au. The light is of visible or near-infrared wavelengths which do not cause skin burning or DNA damage. LED is safe for virtually all skin types and tones – there’s no risk of hyperpigmentation or burning, as long as proper protocols are followed. Side effects are extremely minimal; at most, some people might experience a bit of temporary skin brightness or tightness after a session, but no pain or peeling. Even sensitive skin tolerates LED well. It’s so safe that it’s often recommended as a regular maintenance therapy for those who want to keep their skin in optimal conditionmolechex.com.au.
How LED can help you: For our patients with moles or those who’ve undergone mole removal, LED therapy can be a useful complement. While LED won’t shrink a mole or remove it, red LED light can help the skin heal after a removal procedure by boosting collagen and reducing inflammation at the sitemolechex.com.au. This could mean a nicer final scar outcome and faster resolution of any redness. Additionally, if you’re starting a new skincare routine (for example, focusing on sun protection and anti-aging to prevent new sun damage), periodic LED treatments can enhance your skin’s overall glow, texture, and clarity. It’s a relaxing treatment – many patients use it as a quick “skin boost” with no side effects. Think of it as helping your skin cells function at their best.
In summary, LED therapy is “food for your skin” in terms of light energy. It is accessible, safe, and effective for a broad range of skin benefitsmolechex.com.au. We make use of this technology to support our patients’ skin health, especially in combination with other treatments. If you’re interested in LED sessions (either standalone or as part of your post-mole-removal care), we’d be happy to discuss a plan tailored to your skin’s needs.
Taking care of your skin can help keep your moles healthy and prevent avoidable problems. Here are some practical skin care tips and notes on products (cosmeceuticals) that can either help or irritate moles:
Key takeaway: For healthy skin with moles, moisturize regularly, avoid harsh treatments on the moles, protect from sun, and do not use unverified “mole removal” products or methods on your own. If you maintain a good skincare routine – gentle cleansing, moisturizing, sunscreen every day – your skin (and moles) will thank you. And always feel free to ask your dermatologist about any product you’re unsure of. We’re here to guide you on what’s beneficial and what might be risky.
