Quick Answer: In everyday OTC use, hydrocortisone cream and "cortisone cream" (like Cortisone-10) are essentially the same active ingredient—both deliver hydrocortisone at 1% concentration. Cortisone is a prodrug that your body converts to hydrocortisone. The real decisions are about strength (0.5% vs 1%), formulation (cream vs ointment), and how long you use it. For most mild skin irritations, OTC 1% hydrocortisone applied for up to 7 days is safe and effective. For anything persistent, see a dermatologist.
Walk down the pharmacy aisle and you'll see shelves full of "cortisone cream" and "hydrocortisone cream" in different boxes, at different prices, from different brands. It's confusing—are these the same thing? Different strengths? Does the brand matter?
Let's clear up the confusion once and for all, and help you understand exactly what you're putting on your skin and when to use it.

The Science: Cortisone vs Hydrocortisone
To understand the difference—or lack thereof—between these products, you need to know a little biochemistry.
Cortisone: The Prodrug
Cortisone is a naturally occurring corticosteroid hormone produced by the adrenal glands. However, cortisone itself is biologically inactive. It's a "prodrug"—your body must convert it into hydrocortisone (also called cortisol) using an enzyme called 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) before it can reduce inflammation.
Hydrocortisone: The Active Form
Hydrocortisone (cortisol) is the biologically active form. When you apply hydrocortisone cream, it works immediately on the skin's glucocorticoid receptors to suppress the inflammatory cascade—reducing redness, swelling, itching, and irritation without needing conversion.
Here's the practical takeaway: Every OTC "cortisone cream" on store shelves—including Cortisone-10, the most popular brand—actually contains hydrocortisone as the active ingredient, not cortisone. Pure cortisone is not used in topical OTC products. The name "cortisone cream" is a marketing convention that stuck.
How Hydrocortisone Works on Your Skin
Hydrocortisone is classified as a low-potency (Class VII) topical corticosteroid. Here's what happens when you apply it:
- Penetrates the skin: Hydrocortisone molecules pass through the outermost skin layer (stratum corneum) and bind to glucocorticoid receptors in skin cells
- Suppresses inflammation: It inhibits the production of prostaglandins, leukotrienes, and other inflammatory mediators that cause redness, swelling, and warmth
- Reduces itching: By calming the inflammatory response, hydrocortisone interrupts the itch-scratch cycle that worsens many skin conditions
- Constricts blood vessels: Mild vasoconstriction reduces redness and swelling at the application site
- Stabilizes cell membranes: Prevents the release of histamine and other itch-causing chemicals from mast cells
OTC Strengths and Formulations
Available OTC Strengths
| Strength | Potency | Best For |
|---|---|---|
| Hydrocortisone 0.5% | Lowest OTC | Very mild itch, children, sensitive areas |
| Hydrocortisone 1% | Maximum OTC | Most rashes, eczema flares, bug bites, contact dermatitis |
| Hydrocortisone 2–2.5% (Rx) | Low-medium Rx | Moderate eczema, dermatitis requiring prescription |
Cream vs Ointment vs Lotion
- Cream: Water-based, absorbs quickly, non-greasy. Best for weeping or moist rashes and daytime use on visible skin. Most popular formulation
- Ointment: Petroleum-based, thicker, more occlusive. Delivers hydrocortisone more effectively and keeps skin moisturized longer. Best for dry, scaly, or thickened skin (chronic eczema). More potent per percentage than cream
- Lotion: Thinnest consistency, easiest to spread over large areas. Best for hairy areas or large body surfaces. Least potent delivery
Dermatologist tip: An ointment formulation of 1% hydrocortisone is actually more potent in practice than a 1% cream because the ointment base enhances absorption. If you're not getting relief from a cream, try switching to the ointment version before stepping up to a prescription.
Conditions Treated
OTC hydrocortisone (1%) is appropriate for a range of mild to moderate skin conditions. Here's what it works well for—and what it doesn't.
Good Candidates for OTC Hydrocortisone
- Insect bites and stings: Reduces itch and swelling from mosquito bites, bee stings, chigger bites
- Mild eczema (atopic dermatitis): Manages minor flares on the body; not for chronic daily use
- Contact dermatitis: Poison ivy, poison oak, nickel allergy rashes, reaction to detergents or fragrances
- Heat rash (miliaria): Calms inflammation from blocked sweat ducts
- Minor skin irritation: Chafing, razor burn, mild sunburn itch
- Seborrheic dermatitis: Mild dandruff-related rashes on the face or scalp
NOT Appropriate for OTC Hydrocortisone
- Fungal infections: Ringworm, athlete's foot, jock itch—hydrocortisone can suppress symptoms while the fungus spreads, making it worse
- Bacterial skin infections: Impetigo, cellulitis, infected wounds require antibiotics, not steroids
- Acne: Steroids can worsen acne or cause steroid acne with prolonged use
- Rosacea: Topical steroids cause rebound flares and worsening of rosacea
- Severe or widespread eczema: Requires prescription-strength treatment and medical supervision
Important warning: Never use hydrocortisone cream on a rash if you're not sure what's causing it. Applying corticosteroids to fungal infections (ringworm, athlete's foot) is a common mistake that suppresses visible symptoms while allowing the infection to spread deeper and wider. If a rash doesn't improve within 7 days, see a doctor for proper diagnosis.
Side Effects and Risks
OTC hydrocortisone at 1% is one of the safest topical medications available, but side effects can occur—especially with prolonged or improper use.
Short-Term Use (Up to 2–4 Weeks)
- Mild stinging or burning: Brief, upon application—usually resolves in minutes
- Skin dryness: Particularly with cream formulations
- Allergic contact dermatitis: Rare reaction to the steroid itself or inactive ingredients in the product
Prolonged or Improper Use
- Skin thinning (atrophy): The most significant risk with extended use, especially on thin-skinned areas (face, eyelids, groin, underarms)
- Telangiectasia: Visible spider-like blood vessels under thinned skin
- Stretch marks (striae): Especially in skin folds and on the inner thighs
- Perioral dermatitis: A stubborn rash around the mouth, triggered by facial steroid use
- Steroid rosacea: Redness, burning, and pustules on the face from chronic facial steroid application
- Rebound flare: Symptoms can return worse than before if steroid is stopped abruptly after prolonged use
- Secondary infection: Suppressed immune response at the site can allow bacteria or fungi to grow
Popular Brand Comparison
| Brand | Active Ingredient | Specialty | Price Range |
|---|---|---|---|
| Cortisone-10 | Hydrocortisone 1% | Multiple formulations (intensive healing, feminine, eczema) | $6–$12 |
| Cortizone-10 Plus | Hydrocortisone 1% + moisturizers | Added aloe and vitamins | $8–$14 |
| Aveeno 1% Hydrocortisone | Hydrocortisone 1% | Oat-enriched formula for sensitive skin | $7–$10 |
| Store-brand generic | Hydrocortisone 1% | Same active ingredient, lower price | $3–$6 |
Save money: Generic store-brand hydrocortisone 1% cream contains the exact same active ingredient at the same concentration as brand-name products. The FDA requires identical bioequivalence standards. The only differences are in inactive ingredients (moisturizers, fragrances, preservatives), which rarely affect therapeutic outcomes.
The Bottom Line
- "Cortisone cream" and "hydrocortisone cream" sold OTC are the same active ingredient—hydrocortisone at 1%
- OTC 1% hydrocortisone is safe and effective for mild itch, rashes, eczema flares, and insect bites when used as directed
- Ointment formulations are more potent than creams for dry, scaly skin conditions
- Limit use to 7 days on the face and 2–4 weeks on the body without a doctor's guidance
- Never use on fungal infections—steroids mask symptoms while the infection worsens
- Generic is fine: Store-brand hydrocortisone 1% works identically to Cortisone-10 at a fraction of the price
The bottom line is simple: whether the box says "cortisone cream" or "hydrocortisone cream," you're getting the same medicine. Pick whichever is cheapest or feels best on your skin. And if your rash isn't improving after a week, put the tube down and call a dermatologist—the underlying cause matters more than the brand name on the box.
