4 Skincare Devices for Repairing Your Skin Barrier

Here are three skincare devices that Cassandra loves. These skincare devices are very unique, and although they are not essential, these have definitely enhanced Cassandra’s life.

FENCHILIN Travel Compact Mirror - $149.99  


This is a UV mirror, and it shows the UV protection that’s on your skin. More simply, it shows you where your sunscreen has been applied and if you’ve put it on enough. 

This device has two parts. There's one with a regular mirror, and then, there's one with a UV mirror. So, when you put sunscreen on, you can see whether you've missed a spot. This is very important because as an esthetician, Cassandra always sees people who miss certain spots. They often miss spots right above their lip, below their nose, between the eyebrows, and the ears. This also helps you see how thick of a layer you’ve applied.

Cassandra doesn’t use this device every day. But, if she’s testing a new sunscreen or using a sunscreen stick, she’ll use it. Although stick sunscreens can help to avoid missing a spot, they often apply invisibly. So, a UV compact mirror can help you see where it’s been applied. 

You can also use this device to see when the SPF wears off during the day and how long the sunscreen holds up. That way, you’ll know when it’s time to reapply. Applying your sunscreen properly plays a huge part in protecting your skin from damage, retaining moisture, and healing.

AMTAST Portable Pen Type pH Meter - $59.99

This tests the pH of different items and the pH of your skin. PH stands for “power of hydrogen” or potential hydrogen, and it measures how acidic or basic something is. The best pH for our skin is between 4.7 and 5.75. When the pH of your skin becomes too acidic or too basic, it can lead to dryness and flakiness.


When the skin is too acidic, your skin can dry out or lose some of its natural oils. A disruption in the balance of your skin’s natural oils can lead to inflammation and likewise, breakouts. And when there's itching and redness, your skin barrier can become compromised.

Fortunately, when you use this device to test your skin’s pH, it can help you take preventative measures for maintaining your skin barrier. 

Moreover, if you need to restore your skin’s pH, it helps you decide what to add or remove from your routine by measuring skin products’ pH. 

Essentially, not only does it tell you the pH of your skin, it also tells  how acidic and potent a product is. And upon having this information, it will be easier to create your skincare routine, especially if you need to decrease or increase your skin’s pH.

This also supports your understanding of what product to mix and not to mix. Sometimes, applying more than one acidic product can sensitize the skin and impact the skin barrier.

Skin Inc TRI-LIGHT™ +SABI AI - $295

This measures the hydration inside of your skin. You can have skin that’s oily to the touch but within, it's dehydrated. So, this shows hydration levels on different areas of the skin and quantifies it. Skin hydration is a huge part of building the skin barrier and keeping it healthy. This also has an LED component, but Cassandra hasn’t seen much benefit from this feature. 

ThermoPro TP50 Digital Hygrometer Indoor Thermometer  - $13.99

The hygrometer tells Cassandra the ambient temperature and humidity of the room she's in. Cassandra travels often so she experiences many different climates and temperatures. 

However, using this device has helped Cassandra realize that her skin feels way more refreshed when the humidity is above 60. And when the humidity is over 90, her hair gets very hydrated even though it becomes frizzy. 

This device can also inform us when we need to use a humidifier. Dry air and cold rooms can cause transepidermal water loss in the skin. In low-humidity environments, the air is dry and may cause water to evaporate from the skin faster, leading to more transepidermal water loss. 

Plus, being able to track humidity levels, room temperatures, and climates helps you understand how to shape your skincare routine in different environments. 

Overall, the hygrometer can help you anticipate what your skin will needs in certain environements. You can also use the hygrometer with the pH meter to see how the current temperature and humidity is affecting your skin’s pH.

Ultimately, these products are not essential, but they have definitely transformed Cassandra’s skincare habits, and they have totally elevated her different skincare routines.
