What Are Benign Skin Lesions & Growths?

Benign skin lesions and growths are non-cancerous skin abnormalities arising from various skin cells and structures, presenting with a wide range of appearances depending on their cellular origin. Causes range from UV exposure, natural ageing, and genetics to hormonal fluctuations and skin friction. Common forms include skin tags, moles, seborrheic keratosis, sebaceous hyperplasia, angiomas, and syringomas.

Benign Skin Lesions

What Are the Main Forms of Benign Skin Lesions and Growths?

Skin Tags or
Soft Fibromas

Skin tags - benign skin lesions

Small, soft, flesh-coloured to darkening growths hanging from the skin on a thin stalk, commonly appearing on the neck, underarms, and eyelids.

Cause: Repeated friction in skin folds – more common in those with genetic predisposition, obesity, insulin resistance, or hormonal changes such as pregnancy.

Moles or
Nevi

Moles - benign skin lesions

Pigmented growths ranging from flat to raised, presenting anywhere on the body as junctional (flat), compound (slightly raised), or intradermal (raised, skin-coloured) moles.

Cause: Genetics and cumulative UV exposure – most developing in childhood and early adulthood, with UV increasing their number over time.

Seborrheic Keratosis

Seborrhoeic keratosis - benign skin lesions

Waxy, stuck-on growths with a rough surface, ranging from skin-coloured to dark brown or black, common in adults over 40 on the face, chest and back.

Cause: Natural ageing, cumulative UV exposure, and genetic predisposition –  a family history significantly increases the likelihood of multiple lesions.

Sebaceous Hyperplasia

Sebaceous hyperplasia - benign skin lesions

Small, yellowish, donut-shaped bumps with a central depression, commonly on the nose, cheeks, and forehead, most prevalent in adults with oily skin.

Cause: Natural ageing, UV exposure, androgen hormones, and genetic predisposition to sebaceous gland overactivity.

Cherry Angiomas & Spider Angiomas

Cherry angiomas - benign skin lesions

Cherry angiomas (image) are small, bright red, dome-shaped spots on the trunk, arms, and legs. Spider angiomas present as a central red spot with radiating vessels resembling spider legs, common on the face, neck, and chest.

Cause: Cherry angiomas – natural ageing, genetics, UV exposure, and skin trauma. Spider angiomas – hormonal fluctuations during pregnancy or liver dysfunction, genetics, and UV exposure.

Syringomas

Syringomas - benign skin lesions

Small, flesh-coloured to yellowish growths arising from eccrine sweat glands, appearing in clusters under the eyes and on the cheeks, most common in women.

Cause: Genetics – with a strong association in individuals with Down syndrome – and hormonal fluctuations, particularly oestrogen.

  • Natural Ageing – ageing is the most consistent cause across all benign lesion types, as skin cells become less regulated with age, increasing the likelihood of benign growths – particularly seborrheic keratosis, sebaceous hyperplasia, and cherry angiomas.
  • UV Radiation – cumulative sun exposure drives benign skin lesion development, with risk increasing with age – particularly seborrheic keratosis, moles, sebaceous hyperplasia, and angiomas.
  • Genetics – genetic predisposition influences both the likelihood and number of benign lesions, with a family history being one of the strongest predictors of individual susceptibility – particularly seborrheic keratosis, moles, and skin tags.
  • Hormones – fluctuations during pregnancy, puberty, menopause, or from certain medications drive the development of skin tags, spider angiomas, and syringomas, with androgen hormones specifically contributing to sebaceous hyperplasia.
  • Skin Friction and Trauma – repeated friction in skin folds drives skin tag formation, while skin trauma can also trigger cherry angioma development – more common in those with obesity or who wear tight clothing.

How To Prevent or Minimise Benign Skin Lesions & Growths?

Summary Skin Cancer - Anova Skin Clinic

⚠️ANNUAL SKIN CANCER CHECKS

  • In Australia’s high UV environment, annual skin cancer checks with a dermatologist or skin cancer trained medical doctor are strongly recommended
  • Doctor’s clearance confirming a lesion is benign is required prior to any removal treatment, particularly for any rapidly growing, changing, bleeding, or asymmetrical lesion where malignancy must be excluded.
Summary Hyperpigmentation SPF 50 - Anova Skin Clinic

DAILY SPF 50+

  • Daily Broad-Spectrum SPF 50+ – provides high and broad protection against UVA and UVB radiation, both of which contribute to benign lesions and growths.
  • All-Year-Round – used indoors and outdoors even on cloudy days as UVA penetrates glass and cloud cover year-round.
Summary Hyperpigmentation Protective Clothing - Anova Skin Clinic

PROTECTIVE CLOTHING

  • UPF 50+ Wide-Brim Hat – made of fabric with a certified Ultraviolet Protection Factor of 50+ and a brim of 7.5cm or wider to reduce direct UV radiation exposure to the face, ears and neck.
  • UPF 50+ Clothing – made of fabric with a certified Ultraviolet Protection Factor of 50+ to protect frequently sun-exposed areas such as the neck, chest, arms and legs.
Summary Hyperpigmentation Sun Avoidance - Anova Skin Clinic

SUN AVOIDANCE

  • When the UV index is high, sun exposure should be avoided or shade sought where possible. This is especially important between 10am and 4pm, during summer, and in locations closer to the equator.

What Skincare Ingredients Help with Benign Skin Lesions & Growths?

⚠️Skincare ingredients do not remove existing benign skin lesions and growths, but rather support skin health, reduce rate of skin ageing, slow lesion or growth progression, and address associated concerns such as inflammation, excess sebum, and skin discolouration. If lesion or growth is present and in need of a cosmetic removal, it requires a professional removal treatment.
