Rosacea Treatment- a Dermatologist’s Guide

In this article, our dermatologist Dr. Teo Wan Lin of TWL Specialist Skin & Laser Centre breaks down how skin specialists diagnose and treat skin redness.

Rosacea is a common skin disease that characterizes the tendency to blush or flush more easily than others. The redness can spread slowly between the nose and cheeks, to the chin and forehead. Even the ears, back and chest can be red all the time.

Dermatologist talks subtypes of rosacea 

The following are the clinical subtypes a rosacea dermatologist will use to categorise the disease. 

  1. Erythematotelangiectatic
    Redness, flushing, visible blood vessels
  2. Papulopustular
    Redness, swelling, and acne-like breakouts
  3. Phymatous
    Thickened skin and a bumpy texture
  4. Ocular
    Irritated, red eyes, swollen eyelids, may have what looks like a sty

Causes of rosacea 

The exact cause of face redness is unknown. Redness can result from abnormal dilation of facial blood vessels, leading to constant inflammation that causes chronic swelling and skin thickening changes, also known as phymatous effects. 

Demodex Mite Hypothesis

It is hypothesized that there is a role that demodex mite, a type of mite that lives on individuals’ skin, may play a role in the development of rosacea. Demodex folliculorum is a common commensal of healthy skin but overproliferation leads to eyelid inflammation and signs of ocular rosacea.

Immune System and H.Pylori in Rosacea

The immune system can affect the way the skin of rosacea patients reacts to a certain bacteria, known as Helicobacter pylori. Treatment to eradicate H. pylori such as metronidazole, also beneficially influence the clinical outcome of rosacea. Cathelicidin is a protein that is present on the skin to protect it from infections. However, this can cause redness and swelling in rosacea. Antimicrobial peptides (AMP) can bring out an exaggerated response of the innate immune system. In short, doxycycline, tetracyclines and azelaic acid can block this inflammation.

Treatment for Rosacea

There is no cure for rosacea, but with help from a rosacea dermatologist, you can successfully control it. While medicine or laser treatments can help to reduce symptoms of rosacea, your everyday lifestyle habits are important in treating rosacea and preventing flare-ups. 

Currently, there are 5 topical agents approved by US FDA for use in rosacea, i.e. topical metronidazole, azelaic acid, sodium sulfacetamide-sulfur, brimonidine and most recently, topical ivermectin. For oral agents, only tetracyclines are US FDA approved. For individuals with mild to moderate rosacea, topical treatments with light and laser therapy may be sufficient. Moderate persistent or severe types of papulopustular rosacea may require oral medication. For all subtypes, cosmeceutical active ingredients mentioned below are helpful adjuncts, as they are anti-inflammatory. Aloe and polyphenols in skincare particularly help reduce inflammation in rosacea.

rosacea dermatologist: beauty journal

The Dr. TWL Girl Beauty Journal is used by Dr. Teo’s patients as a mindfulness exercise and to keep track of their skin improvement during the treatment journey. The journal’s paper is perfect for hands-on creativity with watercolour pencils. It contains perforated sheets of colouring pages for the perfect mindfulness activity during the day to relax.

For example, if emotions make your condition worse, consider documenting how you can replace the negative emotion with a positive one. This is a form of cognitive behavioural therapy, also known as cognitive reframing. Journalling is a form of mindfulness exercise that is proven to reduce stress levels, a known trigger for many skin diseases.

Here is a helpful checklist to help record your triggers before your trip to a rosacea dermatologist for treatment.
