How Do Secret Clinical’s Upgrades Support Your Underarm?

Our Secret Clinical collection has recently received a reboot! From the formula side, we now have validated pro-hyaluronic acid formulas, some of which contain hyaluronic acid. You may be wondering why skincare ingredients are necessary in the underarm at all? To understand the importance, we first have to learn about the skin barrier generally.

The skin barrier, or the stratum corneum, is the body’s outermost layer of skin. The skin barrier serves both as the first line of defense, shielding against irritants, pollution, bacteria, and allergens and is the final layer of protection to keep the moisture your body produces within the skin.

We know that approximately 1/3 of consumers still experience some form of underarm discomfort. Strengthening the skin barrier may reduce susceptibility to insults that can result in irritation.

Moisturization for Healthier Skin Barrier:

Our formula moisturizes to strengthen skin’s surface barrier.

1. Secret Clinical pro-hyaluronic acid and hyaluronic acid + vitamin package formulas create a protective layer on the underarm skin’s surface which prevents moisture loss. This protective layer allows the body to both draw in moisture from the environment and protect your natural hyaluronic acid production.

2. We leverage a measure called TEWL, or trans-epidermal water loss, to understand how ‘leaky’ someone’s skin barrier may be. If the barrier is leaky, we know that it would be a weaker barrier than someone who has less leaking because the gaps between skin cells would be more effectively smoothed in. In the case of Secret Clinical’s upgrades, we see an improvement in TEWL indicating that our pro-hyaluronic acid & hyaluronic acid products have benefit to skin barrier strength.

Fighting Oxidative Stress:

Our unique hyaluronic acid + Vitamin Blend fights Reactive Oxygen Species (ROS) damage, helping to protect and rejuvenate your skin’s surface barrier every day.

1. Secret Clinical pro-hyaluronic acid and hyaluronic acid + vitamin package formulas contain antioxidant properties which can fight free radicals that may damage skin.

2. Protecting the skin from oxidative stress may improve the skin surface barrier’s natural integrity and allow the body’s natural hyaluronic acid to function more effectively.

100-Hour Sweat and Odor Protection:

Keep your confidence with Secret's strongest protection with 100-hour sweat and odor defense, ensuring you feel fresh and secure no matter what the day brings.

1. Our Invisible Solid formula features an increased level of surfactants which allows improved penetration of antiperspirant active ingredients for superior protection.

2. This technical innovation ensures that your antiperspirant works effectively, adapting to your body’s unique needs throughout the day.

   When you apply Secret clinical, the formula—a mixture of ingredients—is deposited to the skin’s surface. Surfactants function as a delivery system transporting the sweat to the active ingredient through the total formula and delivering the active to the sweat gland. With an increased number of ‘deliverers’ the active ingredient encounters the sweat gland more quickly, allowing for faster penetration of the active ingredient into the sweat gland, where the antiperspirant plug forms. This upgrade is specific to the Invisible solid clinical formula and does not have implications in deodorant efficacy.
