FAST FACTS
This article delves into the intricacies of seborrheic dermatitis, encompassing its causes, symptoms, and management strategies, with a particular emphasis on its impact on the eyelids—a common manifestation of this condition.
What Exactly is Seborrheic Dermatitis?
Seborrheic dermatitissebaceous glands
The term “Seborrheic” refers to its manifestation in regions of the skin with a high density of sebaceous glands—our skin's oil-producing units [2]. Meanwhile, “Dermatitis” denotes inflammation of the skin.
Affecting approximately 4% of the adult population, seborrheic dermatitis is more prevalent in men than in women. It can emerge during puberty but is primarily seen in adults, with a noticeable increase in cases post-20 years of age, peaking around 30 for men and 40 for women [2].
What Are the Clinical Symptoms?
This condition is characterized by intermittent active phases, which alternate with periods of inactivity [3]. During these active phases, several clinical symptoms may manifest [4]:
Notably, seborrheic dermatitis commonly affects the nasolabial folds, with eyelid inflammation frequently observed along the anterior (lash) line [1].
What Triggers Seborrheic Dermatitis?
While the exact causes of seborrheic dermatitis remain somewhat elusive, it is believed to arise from a complex interaction of various factors. Importantly, this condition is neither contagious nor linked to dietary choices. However, it can be exacerbated by certain illnesses (such as Parkinson’s disease or HIV/AIDS), stress, fatigue, seasonal changes, and a general decline in health [2].
Understanding Eyelid Seborrheic Dermatitis
When seborrheic dermatitis affects the eyelid region, it is clinically referred to as seborrheic blepharitis. It's important to note that not everyone diagnosed with seborrheic dermatitis will develop this specific condition [6].
What Causes Seborrheic Blepharitis?
The term “Blepharitis” simply denotes eyelid inflammation. In this context, it occurs when the eyelids are impacted by seborrheic dermatitis, leading to the involvement of pilosebaceous glands located along the lid margins [3]. This involvement results in a buildup of dead skin cells and sebum, creating an ideal environment for bacteria and other microorganisms to proliferate.
Given that the skin on the eyelids is exceptionally thin—approximately four times thinner than facial skin—and highly sensitive [7], this area is particularly susceptible to secondary bacterial infections [1].

How Can One Treat Seborrheic Dermatitis on the Eyelids?
The involvement of the eyelids, as previously mentioned, typically coincides with seborrheic dermatitis, necessitating concurrent treatment for the underlying dermatological issue [3].
Treatment Options for Seborrheic Dermatitis
It is advisable to consult with a dermatologist who can offer tailored guidance and prescribe an appropriate treatment regimen based on the severity and specific areas affected.
Although a complete cure for seborrheic dermatitis is not feasible, as sensitivity to Malassezia yeasts persists, effective management is achievable with antifungal treatments that can alleviate symptoms without eradicating the underlying issue [2].
The primary objectives of treatment are to minimize the visible signs and alleviate itchiness and redness [5]. Treatment strategies may include [5]:
As seborrheic dermatitis is a chronic condition, ongoing maintenance therapy is often essential [5].
What Are the Recommended Eyelid Treatment Strategies?
Your physician should provide guidance on the appropriate home care regimen. Typically, treatment involves the following steps:
1. Maintaining Eyelid Hygiene
Effective managementDaily routines
Step 1: Use warm compresses to loosen crusts on the eyelids [9], facilitating easier cleaning. A warm facecloth applied for 5 to 10 minutes can be effective [8].
Step 2: Gently cleanse the eyelids and eyelashes utilizing diluted baby shampoo as a mild detergent to help remove lash debris, crusting, and flaking [3], employing a cotton swab (ensuring a different one for each eye). This cleaning may be performed once or twice daily until the crusts are fully cleared [6].
In certain cases, your doctor might recommend an over-the-counter eyelid cleansing product, like a Tea Tree Eyelid Cleanser or Eyelid Cleansing Wipes, instead of baby shampoo.
For moderate to severe cases, additional treatment options may be necessary, such as antiseptic lid cleansing or eyelid micro-exfoliation (BlephEx) [3].
2. Applying Medication as Needed
In some scenarios, your doctor may prescribe a topical antibiotic, ideally in ointment form for better adherence to the eyelids [8]. The antibiotic ointment should be applied after appropriate
