O’Keeffe’s Working Hands is safe for most adults when used as directed on hands and body. It’s fragrance-free, contains no dyes, and scores well on allergen databases, rating 91% free of the top 11 most common skin allergens identified by Mayo Clinic research. That said, a couple of its preservatives deserve a closer look, and the cream isn’t ideal for every skin type or every part of your body.
What’s in the Formula
The cream’s base is simple: water, glycerin, and a mix of fatty alcohols and waxes that form a moisture-sealing barrier on the skin. Glycerin pulls water into the outer layer of skin, while ingredients like paraffin wax and dimethicone (a silicone) sit on top and slow evaporation. This combination is why the cream feels like it lasts through handwashing. Occlusive moisturizers like paraffin can reduce water loss through the skin by up to 99%, which explains the cream’s reputation for repairing dry, cracked hands.
Cosmetic-grade paraffin and mineral oil derivatives have been thoroughly studied. By the time petroleum products reach consumer skincare, they’re heavily refined, inert, and stable. They don’t penetrate deeply into skin or cause reactions in the vast majority of people.
The Preservatives Worth Knowing About
O’Keeffe’s Working Hands contains two preservatives that sometimes raise questions: diazolidinyl urea and iodopropynyl butylcarbamate.
Diazolidinyl urea is a formaldehyde-releasing preservative. That sounds alarming, but it’s widely used in cosmetics and permitted under both U.S. and EU regulations. In water-based products, the compound slowly breaks down and releases small amounts of formaldehyde, which is what actually kills bacteria and extends shelf life. A product containing 0.5% diazolidinyl urea can release up to about 0.215% free formaldehyde. The EU caps free formaldehyde in cosmetics at 0.2% and requires labeling above 0.05%.
For most people, this trace amount causes no issues. The concern is primarily for people with a known formaldehyde allergy or sensitivity, which affects a small percentage of the population. If you’ve ever had a positive patch test for formaldehyde, this cream could trigger contact dermatitis: redness, itching, or a rash where you applied it. The same goes for iodopropynyl butylcarbamate, which can occasionally cause allergic reactions in sensitive individuals.
If you have no history of preservative sensitivities, these ingredients are unlikely to cause problems at the concentrations used here.
Using It on Your Face
O’Keeffe’s Working Hands is formulated for thick hand skin, not the thinner, more sensitive skin on your face. The cream contains several occlusive and emollient ingredients that can clog pores, particularly around the nose and chin. Some users report breakouts after facial application, while others tolerate it fine. If you’re prone to acne or have oily skin, it’s best to keep this cream below the neckline. The American Academy of Dermatology generally advises against applying petroleum-based occlusives to acne-prone facial skin.
Safety for Children
The standard O’Keeffe’s Working Hands cream is generally considered safe for children over age two. Younger children have thinner, more permeable skin, and the preservative load may be less appropriate for infants and toddlers. For kids under two, a simpler barrier cream with fewer active preservatives is a better choice.
Pregnancy and Breastfeeding
The standard Working Hands cream (the green jar or tube) doesn’t contain any ingredients that are typically flagged during pregnancy. However, O’Keeffe’s also makes a “Working Hands Pain Relief” version that contains lidocaine, a topical anesthetic. That product carries an explicit warning to ask a healthcare professional before use if you’re pregnant or breastfeeding. Make sure you’re looking at the right product, as the packaging can look similar.
Who Should Avoid It
The cream is a poor fit for a few specific groups:
- People with formaldehyde allergies. The diazolidinyl urea preservative releases trace formaldehyde, enough to trigger reactions in sensitized individuals.
- People with open wounds or deep cracks. While the cream is designed for rough, dry skin, applying it to actively bleeding or broken skin can cause stinging and may trap bacteria under the occlusive barrier.
- Acne-prone skin on the face. The heavy occlusives are designed for hands and can clog facial pores.
- Infants under two. Their skin absorbs ingredients more readily, and gentler formulations are more appropriate.
Signs of a Reaction
If you’re trying O’Keeffe’s Working Hands for the first time, apply a small amount to one hand and wait 24 hours. Contact dermatitis from preservatives typically shows up as redness, itching, or tiny blisters at the application site within a day or two. A mild tingling on very dry skin when you first apply it is normal and usually fades within minutes. Persistent burning, swelling, or a spreading rash is not normal and means you should wash the cream off and avoid further use.
For the vast majority of users, O’Keeffe’s Working Hands is a straightforward, effective hand cream with a clean safety profile. Its ingredient list is short compared to many competing products, and the absence of fragrance and dyes removes two of the most common triggers for skin irritation.
