More experts choose Secret Clinical Strength as the best deodorant than any other product. It contains 20 percent aluminum zirconium tetrachlorohydrex glycine, an active antiperspirant ingredient that's just short of prescription strength. Secret also contains moisturizers to ensure that it is less irritating than prescription antiperspirants. Secret Clinical Strength comes in solid form and is available in 10 varieties, including one for sensitive skin.
Excellent protection without a prescription. Secret Clinical Strength contains 20 percent aluminum zirconium tetrachlorohydrex glycine, which is within over-the-counter guidelines but is purported to provide comparable wetness protection to prescription-strength deodorants and antiperspirants. Real Simple editors say, for maximum effectiveness the product should be applied at night. Most user reviewers at Amazon.com and Walgreens.com report that the product successfully staves off odor and wetness, and very few complain about the product leaving white marks on clothing. One Amazon.com user said hiking, exercising and horseback riding were no match for Secret Clinical Strength. A few negative reviews say the product has bulky packaging and a difficult-to-use dispenser.
Pleasant, light scent. Secret Clinical Strength comes in 10 scents: Ooh-La-La Lavender, Fresh Water Orchid, Fearlessly Fresh, All Day Fresh (waterproof), Marathon Fresh, Powder Protection, Light & Fresh, Hypoallergenic (unscented), Serene Citrus, and Calming Aloe. A TotalBeauty.com review touts the product as great-smelling, and the majority of Amazon.com and Walgreens.com reviewers say the scents are pleasant but not overpowering. There are very few complaints about irritation -- most users say the product is fine to use right after shaving, and the hypoallergenic version is great for sensitive skin.
Secret Clinical Strength Antiperspirant/Deodorant is named the best solid antiperspirant by Real Simple magazine, which tested 50 deodorants for this feature. Editors say that it is nearly as strong as prescription products but doesn't cause irritation.
