How is Droplette Different
Not just another spray.
Sure, facial mists exist...but the particles are large and slow, so the droplets pool on the skin, just making it wet. Droplette is fundamentally different. With two unexpected mechanical parts bringing new physical forces to the table, Droplette is the tool that has been missing from your skincare routine.
The Droplette system has three parts that work together to give you the most out of your skincare routine:
Device: delivers ingredients deep into your skin via enhanced mist.
Capsules: contains formulations in daily doses. These are designed to be part of our routine every day. Each capsule has a chip which contains the formulation information and syncs directly with the app so that you can keep track of what you use and when you use it.
App: provides the ability to directly chat with an expert so that you can figure out the best routine for you; it also helps you keep track of the formulations that you’re using and your daily progress.
Over 90% of topicals (such as creams or serums) just sit on top of your skin: the actives never actually absorb into your skin. There are two reasons for this
- Our skin is intended to be a barrier and its primary function is to keep things out, not let things in. In fact, there is a thick layer of skin called the stratum corneum which is a tightly packed set of cell layers which make up the barrier. As a result, only small molecules (those less than 500 Daltons in size) can actually diffuse in. Other molecules get stuck outside because there is no way to physically push them in. Many creams do have penetration enhancers which disrupt the stratum corneum to try and allow molecules to squeeze in. But these are also often the additives that don’t offer any benefit to your skin and can often dry it out or irritate it.
- When you spread a cream or lotion on your skin, the only way for molecules to get inside is through diffusion. Diffusion is a slow process which is limited by the length that a molecule has to traverse. Even with the penetration enhancers included in topical formulations, actives are fundamentally diffusion limited.
Meanwhile, spray-based skincare formulations do create mists - but the droplets that come out of these mists are large (sometimes as big as 1-5 mm in diameter and at least 1000X bigger than our droplets) and they don’t have a sustained source of acceleration. This means that when you spray your face, the droplets will all coalesce together and end up pooling on your skin, leaving it wet.
Droplette is fundamentally different.
Our formulas have no penetration enhancers, but we use two key components inside our device to get actives deeper inside your skin
The first one is called a piezoelectric transducer, or a piezo. When we put electricity through it at a certain frequency, we can make the piezo vibrate. In our case, the piezo contains a steel mesh made of very small holes (about 4 microns in size). When the piezo vibrates, fluids go through this mesh and emerge as a mist - it is kind of like when you shake a sieve to sift flour: except that in our case, the “shaking” is due to the voltage and the “sifted flour” is the formulation being converted into an aerosol. The mist has droplets that are the same size as the mesh - so when they come out of the piezo, they’re about 4 microns in diameter.
This mist that comes out of the piezo alone still doesn’t have the right droplet size or other fluid mechanics properties to enable the deeper delivery that Droplette offers. That’s why we added in a unique pump system: Our pump does three things that no other skincare delivery technologies do:
- The pump reduces the size of the droplets. It sucks in part of the mist and expels it with high velocity. When this accelerated mist hits your skin, the droplets in it get even smaller. In fact, on impact with skin, our droplets get about 30-50 times smaller than what comes out of the piezo alone due to a splash effect. These smaller droplets are also moving fast and have acceleration - meaning they can snake their way through the skin.
- The pump accelerates the mist: You’ll feel this air flow even when no mist is coming out of the device; when there is mist, the air flow is accelerating the droplets into a high-velocity spray to better infuse into skin. Additionally, convection from this airflow can evaporate water from the droplets in the skin but it won’t evaporate the active molecules. Instead, the droplets get more concentrated on your skin - and the more concentrated a droplet is, the more effective diffusion will be. This can be understood by thinking about something as simple as cooking something on your stove. If you put in a greater concentration of spices, the smell moves around the kitchen much faster than if it was greatly diluted.
- The airflow of the pump also serves to very slightly disrupt your skin - just enough to enhance the delivery of molecules. This is a temporary effect (on the order of microseconds) and there is no long-term damage to the skin from it but it helps is deliver molecules deeper inside the skin.
Droplette is ultrahydrating in addition to delivering more actives.
One special aspect of Droplette is that since our formulas are completely water based with minimal preservative systems, we can actually deliver a lot more of this water into your skin using our technology. So in addition to the actives being able to get in deeper, we deliver about 50% more water than what would be delivered topically - and that water also stays in there longer. This allows you to use active ingredients that may otherwise be drying or irritating to your skin without feeling those side effects that you might normally experience.
What does this look like?
Method: Administration of 50 µl of distilled water to the hand region continuously for 30 seconds with Droplette vs. 100 µl of distilled water via topical administration. Both regions (Droplette vs. topical administration regions) were blotted dry at 5 seconds post-administration. Hydration was assessed by visual inspection and the Corneometer CM825 device.
Results: At 24 hours, no discoloration or discomfort was reported in either group. Hydration was increased 58.7% on average when water was administered by Droplette, versus only 22.8% in the control (topical administered water) group.
No subjects reported any discomfort adverse effects within 24 hr follow-up, and described Droplette spray as feeling like a slightly cool mist.
