Maximum Strength Formula

Contains 10% sulfur, the highest concentration allowed in OTC acne medications for powerful blemish-fighting action.

Ultra-Minimal Ingredients

Just 2 ingredients total—no preservatives, fragrances, or fillers needed thanks to the anhydrous (water-free) formula.

Antibacterial + Antifungal

Sulfur naturally kills acne-causing bacteria and Malassezia yeast, making it effective for both regular and fungal acne.

02

Safety & compatibility

SAFE
Pregnancy Safe

Topical sulfur is considered safe during pregnancy. No fetal anomalies have been reported in studies. Consult your doctor for personalized advice.

Breastfeeding Safe

Sulfur can safely be used by nursing mothers. Minimal systemic absorption means negligible transfer to breast milk.

Fungal Acne (Malassezia) Safe

Contains zero fungal acne triggers. Sulfur actively fights Malassezia yeast, making this ideal for pityrosporum folliculitis.

Non-Comedogenic

Oil-free, water-washable formula with a comedogenic rating of 0. Will not clog pores or cause breakouts.

Drying Effect

Can cause dryness and peeling, especially with daily use. Start with once daily and reduce if irritation occurs. Always follow with moisturizer.

Patch Test Recommended

Test on a small area first if you have sensitive skin. Avoid use on broken skin or large areas of the body.

Ingredient breakdown

INGREDIENTS

Sulfur 10%Proven

A time-tested acne-fighting ingredient used since ancient times. Sulfur works through multiple mechanisms: it's keratolytic (exfoliates dead skin), antibacterial, antifungal, and reduces sebum production.

  • Mechanism: Produces pentathionic acid on skin contact, which is lethal to bacteria and fungi including P. acnes and Malassezia
  • FDA Status: Approved OTC acne active ingredient at 3-10% concentration
  • History: Used medicinally in Ancient Greece, Egypt, India, and China for thousands of years
  • Studies: Proven effective for acne vulgaris, rosacea, seborrheic dermatitis, and fungal skin conditions
Characteristic sulfur odor (like eggs or matches) is normal. The smell dissipates after washing off thoroughly.

Polyethylene Glycol (PEG) BaseCarrier

Acts as the vehicle/base for delivering sulfur to the skin. This water-soluble polymer ensures the ointment spreads evenly and rinses off cleanly with water.

  • Function: Emulsifier and solubilizer that creates the smooth, spreadable ointment texture
  • Benefit: Makes the mask easy to remove—simply rinse with warm water
  • Safety: Widely used in cosmetics and pharmaceuticals with established safety profile
The PEG base helps mask the sulfur smell during application, making treatment more tolerable.

Cleanse Thoroughly

Wash your face with a gentle cleanser and pat dry. Ensure skin is clean and free of makeup or sunscreen.

2

Using clean fingers, apply a thin layer to affected areas or entire face. Avoid eye area and broken skin.

4

Rinse Thoroughly

Remove completely with warm water. Use a washcloth or follow with a cleanser to ensure all residue is removed.

5

Moisturize

Always follow with a moisturizer to prevent over-drying. Start with once daily and increase as tolerated.

Who is it for?

WHO

Perfect for you if:

  • You have cystic or hormonal acne that doesn't respond to BP or salicylic acid

Frequently asked questions

FAQ

Yes, topical sulfur is generally considered safe during pregnancy and breastfeeding. Studies have not reported fetal anomalies from topical sulfur use, and minimal systemic absorption means negligible transfer to breast milk. However, always consult your healthcare provider before starting any new skincare treatment during pregnancy or while nursing.

Yes! This is one of the best treatments for fungal acne. The formula contains zero fungal acne triggers and only 2 ingredients. More importantly, sulfur actively fights Malassezia yeast (the cause of fungal acne) through its antifungal properties. Many users with pityrosporum folliculitis report excellent results with this product.

Use with caution and not at the same time. Sulfur can be drying, and combining it with other actives like retinol, AHAs, BHAs, or vitamin C may cause excessive irritation, dryness, or peeling. If you want to use multiple actives, apply them on alternating days or use sulfur in PM and other actives in AM. Always listen to your skin and reduce frequency if irritation occurs.

This product works best for oily, combination, and acne-prone skin types. It's particularly effective for those with cystic acne, hormonal breakouts, and fungal acne. People with dry or sensitive skin can still use it but should start with shorter application times, use it less frequently (2-3x per week), and always follow with a good moisturizer.

Many users see active pimples start drying out within 24-48 hours of first use. Significant improvement in breakouts is typically visible within 1-2 weeks. For long-term acne control and clearer skin texture, consistent use for 4-6 weeks is recommended. Results vary depending on acne severity and individual skin response.

Use it as a 10-minute mask after cleansing. Apply to clean, dry skin, wait 10 minutes, then rinse off thoroughly with warm water. After removing the mask, continue with the rest of your routine (toner, serum, moisturizer, sunscreen). Best used in the evening to avoid immediate sun exposure after treatment.

No, this product is non-comedogenic and will not clog pores. It has a comedogenic rating of 0/5. The formula is oil-free and contains only sulfur and polyethylene glycol. In fact, sulfur helps unclog pores by dissolving the bonds between dead skin cells (keratolytic action) and reducing sebum production.

The product has a shelf life of 2-3 years from the date of manufacture and remains effective for 24-36 months after opening when stored properly. Check the expiration date printed on the jar. Keep the lid tightly closed to prevent the product from drying out. Do not use expired products.

— Skincarisma verdict
4.5 / 5 ★★★★★

Verdict: De La Cruz 10% Sulfur Ointment is a cult-favorite for good reason—it delivers prescription-strength acne-fighting power at drugstore pricing. The ultra-minimal 2-ingredient formula makes it ideal for sensitive and reactive skin types, while the high sulfur concentration effectively tackles stubborn cystic, hormonal, and fungal acne. Yes, the sulfur smell takes getting used to, and the thick texture requires some patience to apply, but the results speak for themselves. For anyone struggling with persistent breakouts who hasn't had success with benzoyl peroxide or salicylic acid, this affordable workhorse deserves a spot in your skincare arsenal. A true holy grail for acne-prone skin.

question
lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
