Ivermectin, Metronidazole & Azelaic Acid for Rosacea, Acne & Pigmentation

Understanding Ivermectin, Metronidazole, and Azelaic Acid

Ivermectin, metronidazole, and azelaic acid are three medications that are often used to treat skin conditions. Each medication works in a different way to help clear up issues like rosacea, acne, and hyperpigmentation.

What is Ivermectin?

Ivermectin is an anti-parasitic medication that was first introduced in the 1980s. It was originally used to treat diseases caused by parasitic infections such as river blindness and elephantiasis. However, ivermectin was soon found to also be effective against the inflammatory lesions caused by rosacea.

In rosacea, the immune system overreacts to normal bacteria on facial skin. This causes redness, swelling, and pimples. Ivermectin is thought to help calm this inflammatory response.

Ivermectin comes as a topical cream, gel, or lotion to apply to the skin. It helps to reduce redness, swelling, and inflammation from rosacea. Some common brand names for ivermectin topicals include Soolantra, Iverhart Plus, and Equell.

What is Metronidazole?

Metronidazole is an antibiotic and anti-inflammatory medication. It’s used to treat inflammatory lesions on the face caused by rosacea. Metronidazole helps reduce swelling, redness, and pimples.

Oral metronidazole is sometimes used to treat rosacea. But topical formulas help deliver the medication directly to affected areas on the face without systemic side effects. Brand names for topical metronidazole include Metrogel, MetroCream, and MetroLotion.

In addition to rosacea, topical metronidazole is also used for inflammatory acne. It helps suppress inflammation associated with breakouts.

What is Azelaic Acid?

Azelaic acid is a naturally occurring acid found in grains like wheat and barley. It has anti-inflammatory, antibacterial, and skin-lightening properties. Azelaic acid topical treatments can help with rosacea, acne vulgaris, and melasma.

For rosacea, azelaic acid works to calm inflammation. It also reduces swelling and redness on the skin from rosacea. For acne, azelaic acid prevents pores from clogging while decreasing inflammation.

One of the biggest benefits of azelaic acid is its ability to lighten pigmented areas on the skin. It prevents cells from creating excess melanin pigment. So it can help fade dark spots and melasma.

Using Ivermectin, Metronidazole, and Azelaic Acid for Rosacea

All three of these ingredients can be beneficial in rosacea skin care routines. Here’s a closer look at how they help treat the symptoms of rosacea.

Reducing Inflammation

A primary feature of rosacea is facial inflammation. Ivermectin, metronidazole, and azelaic acid all have anti-inflammatory properties to help calm this immune response.

Regular use of these anti-inflammatory ingredients can help prevent rosacea flare-ups. Using them when inflammation first appears may help minimize the severity of breakouts.

Clearing Up Lesions

In addition to facial redness, rosacea also causes small, red bumps and pustules known as lesions. Both oral and topical antibiotics are used to treat these blemishes.

Metronidazole is a common topical antibiotic prescribed for inflammatory rosacea lesions. Applying metronidazole twice per day helps clear lesions faster.

Ivermectin and azelaic acid also help combat breakouts and pimples. Although they aren’t antibiotics, they have antibacterial properties to suppress infection-causing bacteria.

Reducing Swelling

Facial puffiness and swelling are also common complaints with rosacea. Ivermectin, metronidazole, and azelaic acid can all help diminish oedema and puffy skin associated with rosacea flare-ups.

Using a combination of these anti-inflammatory ingredients is best for reducing puffiness from rosacea. They work together to minimize swelling and inflammation.

Minimizing Redness

The most apparent symptom of rosacea is pronounced redness, particularly across the cheeks, nose, chin, and central forehead. All three ingredients offer relief from facial redness in rosacea-prone skin.

Azelaic acid, in particular, is highly effective for reducing visible redness. It restricts blood vessels from dilating, which diminishes visible red skin. But ivermectin and metronidazole also calm redness by decreasing inflammation.

Using Azelaic Acid for Hyperpigmentation

In addition to helping rosacea-prone skin, azelaic acid offers unique benefits for treating dark spots and uneven pigmentation.

Fading Dark Spots

One of the most impressive effects of azelaic acid is its ability to fade hyperpigmentation. It works by preventing abnormal melanin production in skin cells.

Melanin is the pigment that gives skin its color. Dark spots form from clusters of melanin produced by damaged skin cells. Azelaic acid slows down this excess melanin production to gradually lighten pigmented areas.

Improving Skin Texture

Hyperpigmentation often contributes to an uneven, blotchy skin texture. In addition to lightening dark marks, azelaic acid improves the look and feel of skin.

It exfoliates dead skin cells and evens skin tone for a smoother, brighter appearance. Regular use of azelaic acid promotes a more uniform complexion.

Treating Melasma

One of the most difficult types of hyperpigmentation to treat is melasma. This disorder causes large patches of discoloration, often on the upper cheeks, nose, lips and forehead.

Because azelaic acid fades existing pigment while preventing new melanin formation, it can gradually reduce the appearance of melasma. Used daily for several months, it may significantly improve the look of melasma.

Acne Vulgaris Treatment with Azelaic Acid

While azelaic acid is lesser known than more common acne fighters like benzoyl peroxide and retinoids, research shows it can be an effective acne treatment.

Preventing New Breakouts

One way azelaic acid helps control acne is by keeping pores clear of the oil and dead skin that contribute to breakouts. It has a comedolytic effect of minimizing buildup within hair follicles.

By preventing blockages in pores that lead to whiteheads and blackheads, azelaic acid stops acne before it starts. Using it twice daily helps maintain consistently clear skin.

Killing Acne Bacteria

The bacteria Cutibacterium acnes (C. acnes) colonizes pores and causes infection deep within follicles. This infection leads to large, red pimples.

Azelaic acid reduces acne by directly destroying C. acnes bacteria. Its antibacterial action reduces bacterial numbers and infection in pores.

Calming Inflammation

Like rosacea, acne vulgaris also triggers significant inflammation. Azelaic acid is a natural anti-inflammatory agent that soothes this immune reaction.

Using azelaic acid prevents excessive inflammation during breakouts. This helps minimize redness, swelling and irritation associated with inflammatory acne lesions.

With both comedolytic and antibacterial effects, azelaic acid is an excellent option for treating mild to moderate inflammatory acne vulgaris. It offers similar benefits as traditional acne treatments but with less irritation and dryness.
