Ingredient breakdown
INGREDIENTSSulfur, USP 5%Proven
A time-tested acne treatment with antibacterial, antifungal, and keratolytic properties. Sulfur has been used medicinally for centuries to treat various skin conditions including acne, seborrheic dermatitis, and fungal infections.
- Mechanism: Works by breaking down the top layer of skin (keratolytic effect), killing bacteria, and reducing excess oil production.
- Research: FDA-approved OTC acne treatment ingredient at concentrations of 3-10%.
- Antifungal: Produces pentathionic acid on skin which is lethal to Malassezia yeast causing fungal acne.
Polyethylene Glycol BaseCarrier
A polymer used as a carrier base to ensure uniform dispersion of the sulfur powder. Creates the smooth, spreadable ointment texture that makes application easy.
- Function: Acts as an emollient base that allows sulfur to be evenly distributed and easily applied to skin.
- Water-Washable: PEG base makes the product easy to rinse off with warm water.
- Fungal Acne Safe: PEG does not feed Malassezia yeast, making this formula safe for fungal acne.

Where it fits in your routine

How to use
HOW TO USECleanse Thoroughly
Start with clean, dry skin. Remove all makeup, sunscreen, and impurities with your regular cleanser.
Apply Thin Layer
Apply a thin layer to affected areas or use as an all-over face mask. A little goes a long way—you don't need to apply thickly.
Wait 10-20 Minutes
Leave on for 10-20 minutes. For sensitive skin, start with 10 minutes. You may feel a slight warming sensation.
Rinse Off
Wash off completely with warm water. The oil-free formula rinses clean without residue.
Follow with Moisturizer
Apply a lightweight moisturizer to prevent dryness. Start with once daily use, gradually increasing to 2-3 times daily if tolerated.

Skin type compatibility

Non-comedogenic and clinically tested. Excellent for hormonal acne, cystic acne, and fungal acne.
Can be drying—use as occasional spot treatment rather than all-over mask. Always follow with rich moisturizer.

Frequently asked questions
FAQYes, topical sulfur is generally considered safe during pregnancy and breastfeeding. No fetal anomalies have been reported with topical sulfur use, and minimal systemic absorption means very low risk of transfer to breast milk. This makes it one of the few effective acne treatments recommended by dermatologists for pregnant and nursing mothers. However, always consult your healthcare provider before starting any new skincare product during pregnancy.
Yes, this product is fungal acne safe! Sulfur has proven antifungal properties and produces pentathionic acid on skin which is lethal to Malassezia yeast—the cause of fungal acne (pityrosporum folliculitis). The simple 2-ingredient formula contains no fermented ingredients, fatty acids, esters, or polysorbates that could feed the yeast. Many users specifically choose this product for treating stubborn fungal acne.
Use caution when combining sulfur with other active ingredients. Since this is a wash-off treatment, you can use other actives in your routine, but not at the same time. Apply this sulfur mask, rinse it off, then wait 15-30 minutes before applying retinol, vitamin C, or chemical exfoliants (AHA/BHA). Avoid using multiple strong actives on the same day when you first start—this can cause irritation. If excessive dryness or irritation occurs, reduce frequency of all actives.
This product is excellent for oily, combination, sensitive, and acne-prone skin types. The 5% concentration is specifically formulated for sensitive skin—gentler than the 10% maximum strength version. It's ideal for hormonal acne, cystic acne, blackheads, and fungal acne. Those with very dry or eczema-prone skin should use with caution and always follow with moisturizer, or consider using only as a spot treatment.
Many users report seeing improvement within 1-3 days, with active pimples drying out and coming to a head faster. More significant improvement in overall acne is typically seen within 1-2 weeks of consistent use. Full results usually develop within 3-4 weeks. Some users experience an initial "purging" period where breakouts temporarily worsen as clogged pores are cleared—this is normal and typically subsides within 1-2 weeks.
Use this product after cleansing but before the rest of your routine. Apply to clean, dry skin as a 10-20 minute mask, then rinse off completely with warm water. After rinsing, continue with your regular routine (toner, serum, moisturizer, sunscreen). You can also use it as an overnight spot treatment on individual pimples—just dab a small amount directly on blemishes and leave until morning.
No, this product is non-comedogenic and clinically tested not to clog pores. It has also been allergy tested. The minimalist formula contains only sulfur and polyethylene glycol base—no oils, fatty acids, or pore-clogging ingredients. In fact, sulfur is keratolytic, meaning it helps unclog pores by breaking down dead skin cells and clearing out sebum buildup.
The product has a 24-month (2 year) shelf life from the date of manufacture. Check the expiration date printed on the packaging. Store in a cool, dry place with the cap tightly closed, away from direct sunlight and heat sources to maintain optimal quality. Do not use after the expiration date—the manufacturer has not studied the safety and effectiveness beyond this date.
Verdict: De La Cruz 5% Sulfur Ointment is an exceptional budget-friendly acne treatment that punches well above its price point. The minimalist 2-ingredient formula makes it safe for sensitive skin, pregnancy, breastfeeding, and fungal acne—a rare combination. While the natural sulfur odor and potential for dryness are drawbacks, the effectiveness for stubborn acne that doesn't respond to benzoyl peroxide or salicylic acid makes this a must-try for anyone struggling with breakouts. At under $8 for a 2.6 oz tube, it offers incredible value compared to prestige brands charging 10x more for similar sulfur concentrations. Highly recommended as a first-line treatment for sensitive, acne-prone skin.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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.
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
Notable Effects & Ingredients

Ingredients Related to Skin Types
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.
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.
