Notable side effects from topical use of sulfur?
The sulfur has been deemed as a safe ingredient for adults at concentrations up to 10% and for periods up to 8 weeks of use. Furthermore, sulfur appears to be safe for pregnant or breastfeeding women, children, and teenagers. Products containing sulfur at concentrations up to 6% have been safely applied every night for 6 nights.
The adverse effects of topical sulfur administration are rare and generally mild. Temporary skin dryness, peeling, redness, slight itching, a sensation of warmth, and tingling are among the most commonly reported side effects at the site of application, in addition to its strong volcanic smell. Indeed, sulfur can excessively dry out the skin and cause irritations. However, its drying effect is less compared to that of benzoyl peroxide and salicylic acid, preferred treatments for pimples for years. Nevertheless, in case of an adverse reaction, stop using the product and consult a healthcare professional.
It is often reported that individuals sensitive to sulfonamides may also be allergic to sulfur. However, this is not the case. People allergic to "sulfa" react to the sulfonamides contained in skincare products, but they do not react to elemental sulfur.
Topical Sulfur: Are there precautions to be taken?
Although skin reactions to sulfur are rare, certain measures can be taken to prevent or limit some of these side effects.
Before applying sulfur-based products on a large area of the skin, it is important toperform a patch test to check for potential sensitivities.
Follow the recommended usage instructions on sulfur-based products to ensure safe and effective use.
If you have very sensitive skin, start with a lower concentration of sulfur and gradually increase the amount over time.
If this is your first time using sulfur, start by applying it once or twice a week and gradually increase the frequency as your skin adapts.
As previously mentioned, sulfur can be drying. Therefore, it is important to follow a product containing sulfur with a moisturizing cream.
Avoid using a sulfur-based product in conjunction with other topical acne treatments, as this can be harmful to the skin and increase the risk of irritation, unless otherwise directed by your doctor.
Do not use sulfur-based products on open wounds or on damaged/irritated skin. This can exacerbate irritations.
Keep topical sulfur away from the eyes, mouth, and mucous membranes.
Limit the use of sulfur-based products. The use of a large number of products containing sulfur (masks, soaps, scrubs, serums, etc.) can compromise the integrity of the skin barrier and lead to excessive skin dryness, making it more prone to irritation.
