Important: Secret Clinical Strength Advanced Solid is designed to be used differently from most other antiperspirants. For maximum effect, it is important to follow directions carefully.
Directions for Use
- Apply Secret Clinical Strength Advanced Solid™ at bedtime. The Advanced Solid will work while you sleep to reduce excess perspiration. It will continue to protect you throughout your next day even if you bathe or shower the next morning. If you apply in the morning, you will still get strong wetness protection; however, for optimal performance apply at night.
- A light layer of Secret Clinical Strength Advanced Solid is recommended. Customize the protection that’s right for your personal needs by adjusting the amount dispensed. The average dose is 2 clicks per underarm.
- For waterproof wetness protection, apply Secret Clinical Strength Waterproof at bedtime and then reapply during your morning routine.
Important Note: Secret Clinical Strength Advanced Solid is for underarm use only. Consult with your doctor if you need antiperspirant protection anywhere else on your body.
Why Does Perspiration Occur?
Sweating is your body’s natural way of giving off heat to maintain your core body temperature. Hot weather, exercise, and stressful situations can make you sweat even more. Secret Clinical Strength Advanced Solid provides prescription strength wetness protection for reducing excessive sweating in the underarm, while being gentle to the skin.
Excessive Underarm Perspiration
Sometimes the body’s mechanism for cooling itself is overactive, resulting in excessive perspiration, especially in the underarm area. This may be caused by a medical condition called hyperhidrosis.

Excessive underarm sweating is not completely understood but it is likely related to hormonal changes and/or a malfunction in the endocrine system. For women who experience this, perspiration can become a debilitating, isolating and embarrassing struggle every day.
For more information on excessive sweating, visit the website of the International Hyperhidrosis Society at www.SweatHelp.org.
What Is an Antiperspirant?
An antiperspirant will temporarily reduce perspiration in the underarm. Generally, an antiperspirant reduces odor like a deodorant because it prevents perspiration which is the stimulation for odor causing bacteria. Plus the fragrance helps to minimize problems with unpleasant odor. The more effective the formula, the more effective and longer lasting the protection.
How Does an Antiperspirant Work?

Once an antiperspirant is applied to the skin, perspiration in the underarm grabs and dissolves the antiperspirant particles, pulling them into the pores and forming superficial plugs that are just below the surface of the skin. These help to reduce the flow of perspiration. The plugs can stay in place at least 24 hours and then are washed away over time.
If Sweating Is Natural, Is Strong Underarm Protection with Secret Clinical Strength Advanced Solid Going to Affect My Body’s Ability to Cool Itself?
Absolutely not! Reducing sweating in the underarm has virtually no effect on the body’s ability to cool itself. The number of sweat glands in the underarms represents a very small area of the body. There are many sweat glands on other parts of your body. So, the vast majority of your body heat is released from other parts of your body.
Why Use at Nighttime?
Women’s core body temperatures vary throughout a 24-hour period, rising during the day and cooling at night. The rate at which you sweat is affected by these temperature variations. At night while the body is at rest, the sweating mechanism slows down as compared to the day when your sweating mechanism must speed up to keep you cool. Nighttime is the ideal time to form antiperspirant plugs because of the slower sweating rate. Secret Clinical Strength has a formula that was designed to be activated at night to take advantage of your body’s natural temperature variations. The improved antiperspirancy protects you the whole next day even if you bathe or shower the next morning.

Who Can Use Secret Clinical Strength Advanced Solid?
Anyone who experiences excessive underarm perspiration will love the benefits of prescription strength wetness protection.
An Important Benefit of Secret Clinical Strength Advanced Solid™ vs. a Prescription Product Is that It Is Less Irritating to Skin.
Some prescription antiperspirants contain the active ingredient aluminum chloride. Aluminum chloride is more acidic than the active ingredient in Secret Clinical Strength. Research has shown that antiperspirants which contain aluminum chloride can be irritating to the underarm skin. In fact, the skin irritation is often so severe that discontinued use is required. In addition, aluminum chloride can be damaging to some clothing, often causing staining and/or discoloration.
Secret Clinical Strength Advanced Solid does not contain aluminum chloride. In fact, its patented formula contains triple-action technology with soothing skin conditioners that help keep your underarms feeling smooth and healthy while providing prescription strength wetness protection.
