Underarm rashes and itching are far more common than most people realize. This delicate area of the body is vulnerable to irritation due to constant friction, sweat accumulation, heat, and even reactions to deodorants, shaving, or tight clothing. When these issues arise, discomfort is often immediate—redness, bumps, and persistent itching can make daily life difficult. Dermatologists have long emphasized that the right topical cream can offer fast relief, reduce inflammation, and protect the skin barrier from further irritation.
The underarm area has unique skin characteristics. It is warm, moist, and often occluded by clothing, making it a breeding ground for bacteria, fungi, and other irritants. Because of this, creams that target both inflammation and infection tend to be the most effective. While some home remedies like aloe vera or coconut oil may temporarily soothe irritation, dermatologists typically recommend clinically tested creams with proven active ingredients for long-lasting relief.
In this guide, we will explore the five best creams for underarm rash and itching, according to dermatologists. These creams have been selected not only for their effectiveness but also for their safety and reputation among users. You’ll also find a closer look at how underarm rashes develop, what factors to consider before choosing a cream, and real user experiences with each product.

Why Underarm Rashes and Itching Happen
Before diving into the creams, it’s important to understand why underarm rashes occur in the first place. Dermatologists often explain that multiple triggers can lead to irritation in this sensitive zone:
- Excessive sweating (hyperhidrosis): Sweat can irritate when it mixes with bacteria, leading to itching and redness.
- Fungal infections: The warm and moist underarm environment creates an ideal breeding ground for fungi like Candida, which cause itching and inflammation.
- Allergic reactions: Deodorants, perfumes, and shaving gels often contain harsh chemicals, leading to contact dermatitis.
- Friction and chafing: Tight clothing or repeated skin-to-skin contact can break down the skin barrier.
- Heat rash: Hot climates or physical activity may cause sweat ducts to clog, resulting in red, itchy bumps.
A good cream should address one or more of these causes by soothing irritation, reducing inflammation, and preventing infection.
What to Look for in a Cream for Underarm Rash
When dermatologists recommend creams for underarm rashes and itching, they emphasize the following qualities:
- Anti-inflammatory properties: Ingredients like hydrocortisone or zinc oxide help calm inflammation.
- Antifungal and antibacterial action: Clotrimazole, ketoconazole, or tea tree oil derivatives fight off infections.
- Moisturizing support: A cream should restore hydration to avoid dryness and cracking.
- Hypoallergenic formula: Since the underarm is sensitive, fragrance-free and non-irritating formulas are best.
- Fast-absorbing texture: Heavy creams may feel sticky, so lightweight formulations are ideal for daily use.
Armed with this knowledge, let’s review five top-rated creams available on Amazon that dermatologists often recommend for underarm rashes and itching.
5 Best Creams for Underarm Rash and Itching, According to Dermatologists
1. Lotrimin Ultra Antifungal Cream
Lotrimin Ultra is frequently mentioned by dermatologists as one of the most effective creams for fungal-related rashes under the arms. It contains butenafine hydrochloride, a strong antifungal agent that targets the root cause of itching and redness.
Features:
- Active ingredient: Butenafine hydrochloride.
- Treats fungal infections like ringworm, jock itch, and candida overgrowth.
- Non-greasy formula that absorbs quickly.
- Provides long-lasting relief with once-daily application.
User Comments:
Many Amazon reviewers praise Lotrimin Ultra for its quick results. Users report that itching often subsides within the first 24 hours, and noticeable improvement in redness occurs within a few days. Some reviews note that, although the cream is slightly more expensive than generic antifungal creams, the results justify the cost. One user mentioned, “After trying multiple drugstore creams, this was the only one that completely cleared my underarm rash. It felt soothing within hours.”
However, a few reviewers noted that it works best when applied consistently. If skipped, symptoms can return, which aligns with dermatologists’ advice to complete the full treatment course.
2. Hydrocortisone 1% Anti-Itch Cream by Cortizone-10
Cortizone-10 is another dermatologist-recommended product for underarm itching caused by allergic reactions or irritation. Its active ingredient, hydrocortisone, is a mild corticosteroid that reduces swelling, redness, and itching.
Features:
- Contains aloe vera for extra soothing.
- Safe for sensitive skin with fragrance-free options.
- Fast-acting relief for itching and redness.
- It can be used for multiple skin conditions, including eczema, psoriasis, and contact dermatitis.
User Comments:
Users often describe this cream as a “miracle worker” for flare-ups. One reviewer wrote, “I had a stubborn underarm rash that wouldn’t go away. Within two days of using Cortizone-10, the redness and itching were almost gone.” Others appreciate the added aloe, which makes the cream feel cooling upon application.
Some customers do mention that it’s not ideal for long-term use, as overusing hydrocortisone can thin the skin. Dermatologists confirm this caution, advising patients to use the cream sparingly and only during flare-ups.
3. Clotrimazole Antifungal Cream by Lotrimin AF
This classic antifungal cream is trusted by dermatologists and widely available. Clotrimazole is its main ingredient, proven effective against fungal infections that commonly occur in moist areas like the underarms.

User Comments:
Amazon users frequently share positive experiences with this cream. One user reported, “After weeks of struggling with itching under my arms, this cream worked wonders within days. The itching stopped almost immediately.” Others emphasize that consistency is key—applying it twice daily is what helps completely clear the rash.
Some negative feedback revolves around the tube size, which some find too small for extended use. Still, its effectiveness outweighs this drawback for most users.

Additional Tips for Managing Underarm Rashes
While creams provide significant relief, dermatologists often remind patients that lifestyle adjustments are equally important in preventing recurring rashes. Here are a few practical tips:
