Your skin is the largest organ of your body. It protects everything inside you from the external environment. But what measures do you take to protect it?

Whether you discover a new rash, bump, or unnerving projections on your skin, it is important to find out the causative agent instead of waving it off. Granted, it may not be alarming enough for a visit to the dermatologist, but there is a way to get it checked out right from your couch—use a dermatology app.

Here are the best dermatology apps to help you diagnose and maintain skin conditions.

1. Aysa

Aysa is one of the most popular apps out there that helps you answer all your questions about your skin. If you want to check something out, you can begin by using the Symptom Checker. All you have to do is tap on the feature and take a picture of the area of skin that seems problematic. The app will provide personalized matches according to your symptoms.

There is a library of more than 120,000 medical images with every skin color and type. Different stages of a skin condition can be viewed in the library, for over 200 skin conditions. You can look at the images, and read about them, to educate yourself and create awareness of different skin conditions.

The app uses VisualDx as its supporting software, which is an award-winning software for support in clinical decisions. It also has strong privacy regulations and promises its users that photos of their skin will never leave their phone, so you have nothing to worry about in that respect.

2. MDacne

Acne is the most common skin condition in the United States. At some point in their life, 85% of people will suffer from acne. Crazy, isn't it? MDacne gives you a complete acne treatment kit, uniquely personalized to your skin. You can use the app to monitor your skin's improvement and compare and contrast with progress photos.

You begin by taking a selfie and allow the app to assess your skin. The app provides you with products that you will need to treat your acne. The products are formulated by dermatologists and contain natural ingredients. There are three products in one treatment box: a cleanser, anti-acne treatment cream, and acne-prone skin hydrating moisturizer, all delivered right to your doorstep.

The best part is that you will get the first month of products for absolutely free. The first month is the trial period, after which you will have to upgrade to a paid subscription to continue getting treated. If you have any questions along the way, you can chat with a dermatologist to address any concerns you may have.

3. First Derm

With over 400,000 users, First Derm is an app that consults real-time dermatologists about your skin concerns instead of relying on algorithms to do the job. It works in over 160 countries and offers seven languages.

Most users are treated with over-the-counter medication, but First Derm recommends physical meetings with the dermatologists it finds near you. You can also get a quick appointment if you share an answer from First Derm.

All the dermatologists on board are trained and certified in teledermatology. They also have a minimum of 10 years of specialized training at the best medical institutions, along with hands-on experience with a senior medical advisory board.

4. scanoma

For anyone with moles, you know what a struggle it can be to decide if each mole's presence is normal or potentially cancerous. Worry no more: this app is the perfect way to find out without lengthy, expensive trips to the doctor.

All you have to do is scan your mole, or any blemish that may look like the onset of a mole in the near future, and the app will let you know if there is anything suspicious by comparing it to similar images of skin diseases. If there is, the app will connect you to a dermatologist.

The medical practitioners involved are experts and are guaranteed to give you a professional opinion. All your information will remain private, and the app is completely free to use. However, remember that scanoma is only capable of detecting moles and will not work accurately for other marks on your skin. The app also does not work with tattooed skin.

5. Miiskin Skin Tracker

Dermatologically endorsed by the Skin Health Alliance, Miiskin is one of the best apps for tracking skincare, moles, and skin changes. It is also a partner to leading skin cancer organizations in the US, Canada, UK, and more. However, this app does not serve as a platform to diagnose skin conditions of any sort; instead, it allows you to keep a virtual skin diary.

With the use of artificial intelligence and a carefully calibrated in-built camera, you can scan any part of your skin that may be worrisome and record your progress with a body chart. You can check out a side-by-side view of all your photos to watch your progress. You can even place your phone far away to get a full-body image of yourself.

The Web Compare feature allows you to access your photos in the app or in the browser for any other device you'd like. You can also share your photos with anyone you like. The app separates the photos you take from the camera roll and encrypts them to protect your privacy.
