Dermatological treatments for two common skin conditions
We would like to draw your attention to two common skin conditions: sebaceous hyperplasia and seborrheic dermatitis. sebaceous hyperplasia and seborrheic keratoses.
Although they can be treated in a similar way, these two pathologies are in fact very different. They are grouped together mainly because of their high frequency, benign nature and potential aesthetic impact.
Sebaceous hyperplasia is linked to an enlargement of the sebaceous glands, while seborrheic keratoses are benign tumors derived from keratinocytes (epidermal cells). They are generally easy to treat, and we’d like to show you the treatment options available for each of these conditions.
Sebaceous hyperplasia: excessive growth of sebaceous glands
Sebaceous hyperplasia is a benign condition characterized by an enlargement of the sebaceous glands (i.e. glands that are larger than normal), which produce sebum. It appears as small yellow or flesh-colored, doughnut-shaped bumps, usually on the face. Common in adults, especially those with oily skin, this condition is often associated with aging and hormonal fluctuations. There are rare cases induced by medication. Although not dangerous, sebaceous hyperplasia can be treated for aesthetic reasons.
Seborrheic keratoses: benign skin growths
Seborrheic keratoses are very common benign skin growths that often appear with age. They are generally genetic in origin, and may be influenced by UV rays. They appear as dry or rough patches, brownish to black in color, with well-defined edges. They are sometimes mistaken for beauty spots due to their dark coloration.
Seborrheic keratoses can appear on various parts of the body, including the trunk, arms and face. Although harmless, they can be aesthetically embarrassing or, in some cases, become irritated and cause discomfort. Despite their benign nature, their appearance and location may lead some patients to consult a dermatologist to evaluate available treatment options.
Treatments available for these conditions
A number of simple, effective solutions are available to deal with these two conditions.
These treatments are generally minimally invasive, with a rapid recovery time, and results are often visible after a few days. However, it’s important to note that redness, scabbing and, in rare cases, scarring or hyperpigmentation may occur.
- Liquid nitrogen treatmentLiquidnitrogen treatment, or cryotherapy, is an effective option, particularly recommended for seborrheic keratoses. This technique involves applying liquid nitrogen to the lesion, causing it to freeze and gradually disappear. This fast, effective treatment is generally very well tolerated.
- Electrodessication treatmentsElectrodessicationis a sub-type of electrosurgery, a procedure in which a low-intensity electric current is used to cause superficial tissue ablation. It is commonly used to treat sebaceous hyperplasia and seborrheic keratoses.
This treatment can be performed with or without local anesthesia, depending on the case. Although it is a more time-consuming treatment, it is often preferred on the face and neck because of its precision and more delicate approach.Following these two procedures, a small scab forms and falls off naturally within a few days. It is crucial to follow recommendations to limit the risk of scarring or hyperpigmentation, notably by protecting the skin from the sun. - Other treatment optionsSebaceoushyperplasia can also be treated with topical retinoids, which help reduce the appearance of enlarged sebaceous glands and improve skin irregularities. These treatments can be used alone or in conjunction with other options, depending on the severity of the condition.
