We’re here to share what we know — but don’t take it as medical advice. Talk to your medical provider if you have questions.

Sulfur, a naturally occurring element, has been used medicinally for centuries for its antimicrobial properties.¹ And today, you can find it in countless products formulated to help fight acne. So how does it actually work?

Our experts are here to help you understand the science behind sulfur's acne-fighting abilities, and how you can safely incorporate it into your skincare routine. By understanding the ABCs of sulfur, you'll be better equipped to combat your breakouts and achieve clearer and healthier skin. Let's dive in!

How is sulfur used in skincare?

Sulfur is widely used in skincare and is often combined with other active ingredients. Many over-the-counter (OTC) and prescription acne treatments have sulfur as a main ingredient; you can find it in a range of products, from soaps to lotions. 

Research shows that sulfur has antifungal and antibacterial properties—so it can help keep your pores clean and fight bacteria, leading to clearer and healthier skin.² For this reason, this element is well-suited for treating acne-prone skin.

Sulfur can be used to treat many skin conditions, including acne vulgaris, rosacea, seborrheic dermatitis, and even warts. It’s especially beneficial when used in combination with other active ingredients such as sodium sulfacetamide or salicylic acid.³

Sulfur for acne treatment

Sulfur can help treat acne because of its antibacterial properties.⁴ Here’s how it works!

Fighting bacteria

It has been shown that when sulfur is combined with sodium sulfacetamide, it stops the growth of acne-causing bacteria, such as Propionibacterium acnes (P. acnes).⁵ Additionally, research shows that sulfur is an effective treatment option for controlling acne vulgaris caused by Staphylococcus bacteria.⁶

Keratolytic effects 

Sulfur has been shown to have keratolytic effects, which means it can help loosen scales and skin flakes. However, like many acne treatments, it's important to strike a balance when using sulfur, as dryness and itching may occur.⁷ 

While sulfur-based treatments can be useful on their own, sulfur is often combined with other topical agents to enhance its effectiveness when treating acne and other skin conditions.⁸ Before trying any new skincare products, make sure you consult with a dermatology provider to get personalized skin advice that is best for your skin.

Who should use sulfur?

Sulfur has been used for centuries to treat different skin conditions.⁹ Sulfur is typically well tolerated, but for some it can be drying. If you experience dryness or irritation, it may be better to try alternative ingredients to fight acne.

It’s essential to consult your dermatologist or healthcare provider before incorporating sulfur into your skincare routine, as they will give you personalized advice based on your skin type and acne severity. If you have any concerns about a potential reaction to sulfur, you can conduct a patch test first and follow the recommended usage instructions before you start using sulfur-based products.

Are there any side effects of using sulfur?

Aside from dryness and itching, side effects are rare with topical use of sulfur.¹⁰ However, if you’re noticing a bad reaction after starting your sulfur-based products, contact your dermatologist and consider other options.

Alternatives to sulfur

Sulfur isn't the only effective acne-fighting ingredient out there. Some of the most common ones include benzoyl peroxide, salicylic acid, and retinoids.¹¹

Here’s a closer look at how they help combat your acne:

Benzoyl peroxide: Benzoyl peroxide is a potent antimicrobial agent that can kill acne-causing bacteria, reduce inflammation, and help to clear blocked pores.¹²

Salicylic acid: Salicylic acid is a beta-hydroxy acid (BHA) that penetrates deep into your pores, exfoliates dead skin cells,¹³ and dissolves excess sebum, which may help prevent acne formation.¹⁴ Using skincare products that contain salicylic acid can help combat your acne.

Retinoids: Retinoids are a group of vitamin A derivatives, such as tretinoin and adapalene, that can help unclog pores, reduce inflammation, and promote cell turnover, resulting in smoother skin and reduced acne.¹⁵

FAQs

Can sulfur damage your skin?

Sulfur's beneficial properties, which may help control sebum production and exfoliate dead skin cells, may cause dryness and irritation for some. These side effects may cause discomfort, particularly if you have sensitive or dry skin.

To minimize the risk of side effects, always follow the recommended usage instructions on sulfur-based products, start with a lower concentration, and gradually increase the amount over time. 

Remember that moderation is key to achieving the best results without compromising your skin's health, and it’s always best to speak with a medical provider before trying any new ingredients on your skin.

Is sulfur enough to get rid of acne?

Sulfur can be an effective component in treating mild to moderate acne, but it may not be powerful enough on its own. Acne is a complex skin condition, influenced by factors such as hormones, genetics, and lifestyle. 

That means you’ll likely need a comprehensive skincare routine and holistic approach to address your acne effectively. Incorporating sulfur with other acne-fighting ingredients like salicylic acid, benzoyl peroxide, or retinoids may enhance its efficacy. 

Additionally, you should maintain a consistent skincare routine, use non-comedogenic products, and address lifestyle factors like diet, stress, and sleep to help improve acne. Always consult a dermatology provider for personalized advice on the most suitable treatment plan for your specific acne concerns.
