At Dermatica, we understand that rosacea can be a challenging journey that isn’t always straightforward, so we’re here to guide you at every step. Today, let’s explore the science behind two important ingredients – Ivermectin and Metronidazole – which can transform your experience with treating rosacea.

What Is Rosacea?

Rosacea is a common and chronic skin condition that mainly affects the face. It’s often characterised by redness, flushing, visible blood vessels (telangiectasia), and sometimes small, red bumps or pustules. It’s mainly noticeable in the centre of the face, including the cheeks, nose, forehead, and chin. In some cases, it can also affect the eyes, leading to symptoms like eye irritation and redness, known as ocular rosacea. (1)

What Causes Rosacea?

Some key factors we know may contribute to rosacea include: blood vessels dilating too easily which causes flushing, inflammation and/or swelling, an overabundance of demodex mites (which naturally inhabit our hair follicles), environmental triggers like UV rays and certain foods, a compromised skin barrier, and if your immune system isn’t functioning properly. (2)


Ivermectin, originally designed to combat parasitic infections, is both an anti-inflammatory and anti-parasitic, which makes it a very good option if you have rosacea.

Ivermectin targets inflamed skin and rosacea bumps, relieving swelling or redness and evening out your skin’s overall appearance. Most people have minimal side effects, but it’s still a prescription ingredient that should only be used under the expert guidance of a dermatology expert to make sure you’re using it correctly.(3)


Metronidazole has been a trusted ingredient for people with rosacea for a while. In the age group of 25 to 65, where rosacea can often become more noticeable and persistent, Metronidazole can give much-needed relief. It’s both anti-inflammatory and antimicrobial, so it’s effective at treating the papulopustular form of rosacea too.

Like Ivermectin, using Metronidazole under the guidance of a dermatology expert is essential to get the best results. (4)
