Know when deodorant or antiperspirant is the better choice
Key Takeaways
- Aluminum-free deodorants help control odor but don’t stop sweat.
- Antiperspirants reduce sweat and odor.
- Aluminum in antiperspirants is safe for most people.
Choosing between an antiperspirant and a deodorant depends on whether your goal is to stay dry, fight odor or both.
Aluminum-free deodorants, often marketed as natural deodorants, have become increasingly popular as more people look for products that do not contain aluminum. Some also prefer deodorants made with plant-based ingredients or formulas that better align with their personal preferences.
Others choose aluminum-free options because they have heard claims linking aluminum in antiperspirants to breast cancer or Alzheimer’s disease. However, current research does not support those claims.
“For most people, there’s no medical reason to avoid aluminum-containing antiperspirants,” says Brittney Ulupinar, MD, an internal medicine physician at Scripps Clinic Carmel Valley. “Think about what you want the product to do. If your main concern is body odor, an aluminum-free deodorant may be enough. If you also want to reduce sweating, an antiperspirant is usually the better choice.”
How antiperspirants and deodorants work
Although they’re often confused, deodorants and antiperspirants work differently.
Deodorants don’t prevent sweating. Instead, they help control body odor by reducing bacteria that cause odor, masking odors with fragrance or doing both.
Antiperspirants reduce both sweat and odor. They contain an aluminum-based ingredients, such as aluminum zirconium, that temporarily form plugs in the sweat ducts. This reduces the amount of sweat that reaches the skin’s surface, helping keep underarms drier and limiting the moisture bacteria need to produce odor.
Both aluminum-free deodorants and antiperspirants are available in sticks, roll-ons, gels, creams and dry sprays.
Is aluminum in antiperspirants safe?
Research has not found evidence linking aluminum in antiperspirants to breast cancer or Alzheimer’s disease. Only very small amounts are absorbed through healthy skin.
“The small amount of aluminum in these products is not absorbed into the body in amounts that would be expected to cause harm,” Dr. Ulupinar says.
Benefits of aluminum-free deodorant
If you’re considering switching to a natural deodorant, here are a few potential benefits:
Lets your body sweat naturally: Aluminum-free deodorants don’t block sweat ducts, allowing your body to cool itself through perspiration.
May be gentler for sensitive skin: Some people find aluminum-containing antiperspirants irritating. However, aluminum-free deodorants may also contain baking soda, fragrances or essential oils that can irritate sensitive skin.
Available in a variety of scents and formulas: With so many options available, it’s easier to find an aluminum-free deodorant you like.
May appeal to people seeking plant-based ingredients: Many aluminum-free deodorants are made with plant-based ingredients or come in recyclable packaging. Some brands are also not tested on animals.
Drawbacks of aluminum-free deodorant
They don’t prevent sweating: If reducing sweat is your goal, an antiperspirant is usually the better choice. Aluminum-based active ingredients are the only FDA-approved ingredients proven to reduce sweating.
Finding the right product may take trial and error: Body chemistry varies, so you may need to try several products before finding one that works for you.
You may need to reapply: Depending on your activity level, the weather and how much you sweat, you may need to reapply throughout the day.
They often cost more: Aluminum-free deodorants are often more expensive than traditional antiperspirants, although prices vary by brand.
Is there a transition period when switching to aluminum-free deodorant?
Some people notice more body odor or sweating after switching to an aluminum-free deodorant. This temporary adjustment usually lasts several days to a few weeks.
Which is right for you?
The best choice depends on whether your goal is to control body odor, reduce sweating or both.
An aluminum-free deodorant may be right for you if you have mild body odor, don’t mind sweating or prefer products without aluminum. If staying dry is your priority or you sweat heavily, an antiperspirant is usually the better choice.
If you have excessive sweating (hyperhidrosis), an antiperspirant is usually the recommended first step. If over-the-counter products don’t provide enough relief, talk with your doctor about prescription-strength antiperspirants or other treatment options.
"The best product is the one you’ll use consistently, and that fits your skin and lifestyle,” says Dr. Ulupinar. “If you have excessive sweating, persistent body odor or ongoing skin irritation, talk with your primary care physician. These symptoms may require a different treatment approach.”
