Moles are incredibly common skin growths that can appear at any stage of life. They usually emerge during childhood and adolescence, gracefully adapting in size and colour as we journey through life. While moles are widespread, the exact cause of their appearance remains somewhat enigmatic, believed to involve a combination of genetic factors and sun damage in many cases1. And while most are harmless, it is not uncommon for individuals to have their moles removed.
Discovering unexpected moles on your face can be concerning, but taking the right steps to address them is essential for your skin’s well-being. Since new moles in adults are more likely to become cancerous, it is vital to monitor them for any changes and seek a mole check if needed. In this article, we explore more about acquired moles and the solutions available to address these unexpected facial moles confidently, ensuring you can navigate this skin concern with knowledge and care.
Causes of acquired moles
Acquired moles, also referred to as common moles, are skin growths that develop after birth. They can emerge anywhere on the skin and are commonly found in individuals with fair skin, ranging from 10 to 40 moles per person. Typically, these moles exhibit various characteristics1, such as:
- Unchanging in size and appearance.
- May have hairs growing.
- Either slightly raised, dome-shaped, or flat profile.
- Oval or round in shape.
- Rough or smooth texture.
- Display a range of colours, such as skin-coloured, blue, pink, red, black, brown, or tan.
- Relatively small, measuring ¼ inch or less, akin to the size of a pencil eraser.
The exact cause behind the appearance of a new mole in adulthood remains uncertain. While melanoma has been extensively studied, there is limited research2 on the factors leading to the development of benign moles. As a result, new moles may either be harmless or potentially cancerous.
Several reasons may contribute to the emergence of a new mole1, including:
- Exposure to factors such as sun exposure, sunburn, or the use of tanning beds.
- Genetic mutations.
- Use of drugs that suppress the immune system or certain antibiotics, antidepressants, or hormones.
- A family history of atypical moles.
- Light or red hair with fair skin.
- Increasing age.
Dealing with unexpected facial moles
If you find yourself dealing with new facial moles and are unsure whether they are benign or cancerous, don’t fret! Here are a few things you can do;
1. Understand normal moles
Before delving too deeply into addressing unexpected moles, it is crucial to understand what constitutes a normal mole. Normal moles, also known as acquired nevi, are typically small, round or oval and have even borders3. They can range in colour from tan to brown, and some may have a slightly raised appearance. These moles often appear during childhood and adolescence, with the number of moles peaking in early adulthood. Generally, normal moles remain stable in size, shape, and colour over time.
2. Monitor for any changes
If you notice a newfound mole on your face, the first step is to closely monitor4 it for any changes. Keep an eye on the size, shape, colour, and borders of the mole. Any changes in these characteristics, such as asymmetry, colour variation, increase in size, or irregular borders, may warrant further evaluation at a dermatology clinic.
3. Consult a dermatologist
If you have any concerns about the newfound moles on your face or notice any changes, do not hesitate to schedule an appointment with a dermatologist. Early detection and professional evaluation can provide valuable insights into any potential skin conditions5 and help ensure prompt and appropriate management.
4. Options for mole removal
Depending on the dermatologist’s evaluation and your personal preference, there are various removal methods available for facial moles. Common removal options include shave excision, surgical excision, and laser removal6. The choice of technique depends on factors such as the mole’s size, location, and characteristics. It is essential to discuss the removal process thoroughly with your dermatologist and address any concerns before proceeding with the procedure.
