Airbrushing is a fabulous way to apply makeup and can be used for various applications, including bridal, film, SFX and high fashion. However, airbrush makeup application is an art form – it takes practice and experience to get proficient. So before rushing in, take time to understand the kit and how it all works. With that in mind, here’s an introduction to the equipment used to airbrush makeup.
What is Airbrushing?
Airbrushing is simply a method of applying cosmetics using specialised airbrushing equipment. It is an alternative method of application to the more traditional ones like brushes, sponges or fingers. Airbrushing is also popular for lots of hobbies and jobs, for example cake decorators, model makers and nail artists.
Airbrush equipment consists of three main pieces of kit – namely an airbrush gun, compressor and hose.
Airbrush Gun
An airbrush gun is the tool used to spray fine mists of makeup onto someone’s skin, hair or prosthetic appliances.
Airbrush guns have two main variations in design. The first relates to how the makeup is fed or supplied to the gun. The second is the type of trigger used on the gun. Whatever the design, the gun is held and moved a bit like a pen.
Types of Feed
There are three ways to supply makeup to the gun:
- Gravity-fed airbrush – has a little cup situated on top for the makeup product to go. A combination of gravity and air pressure sucks the makeup down into a mixing chamber, where it is atomised to a fine mist. This type of gun must be held fairly upright in order to work properly and for the makeup product to stay in the cup.
- Side-fed airbrush – has a cup attached to the side of the airbrush. It works in the same way as the gravity-fed cup, except it’s positioned at the side rather than on top.
- Bottom-fed airbrush – has a plastic bottle attached underneath for containing makeup. This type of airbrush is used more for spray tanning or bodywork, as the bottle holds more makeup than the gravity-fed cup. Also, the makeup is sucked into the gun by negative air pressure. This means that the gun can be used at all angles, which is also useful for bodywork.
Types of Trigger
- Single-action trigger – pressing the trigger releases the airflow and a pre-set amount of makeup together. Ultimately, it is easier to use than a dual-action trigger. However, there is less control over the amount of makeup released.
- Dual-action trigger – this mechanism that controls the flow of air and makeup separately. Pressing the trigger turns the airflow on and releasing it turns the flow off. When the trigger is pressed and then pulled back, the makeup is also allowed to flow. Therefore, pulling the trigger further back releases a little more makeup. This type of trigger allows for more precision application and fine detail work.
Compressor
An airbrush gun has no power of its own. Therefore, it needs to be connected to a supply of pressurised air.
This is usually provided by an air compressor – a mechanical device that compresses air to create pressure. Canisters of pressurised air can also be used but you constantly have to replace these once they are emptied.
However the air compression is sourced, it is this pressure that pulls the makeup into the gun. It then forces it through the airbrush and out of the nozzle, creating the fine mist of makeup.
Features on a Compressor
Compressors come in different sizes and weights, providing options for personal and professional uses. They also come with varying features, including:
- Adjustable PSI – this allows for a variation in air pressure, which is important if you want to do varied work with your airbrush. For example, working on the face needs a much lower PSI than spraying the body. An adjustable PSI means that you can work at the optimum pressure needed for that application.
- Auto shut-off – a compressor is a noisy bit of kit. Some compressors have a feature that will shut off when the compressor is not in use, giving your ears a well-needed break!
- Water trap – some compressors come with one built-in. The more basic units will, most likely, not have one. The water trap does exactly that – it traps water droplets contained in the air and prevents them from getting mixed in with the makeup. This can lead to distortion in the makeup pattern. In a word, a water trap provides clean and dry air.
- Carry handle – handy for larger models, especially to make it more portable.
- Gun holder – some compressors have a little holder for the gun to sit while you work. This keeps the gun safe and secure. If the compressor doesn’t have a holder built-in, you can buy them separately.
Air Hose
This bit of airbrush equipment connects the gun to the compressor. It is a long rubber or braided hose and is attached to the underneath of the airbrush gun.
The connector fitting and thread can vary from brand to brand. Therefore, a hose from one brand might not fit on a compressor from a different brand. Airbrush equipment kits will come with a suitable hose for that particular compressor and airbrush gun. The fitting is just something to remember when replacing hoses.
Airbrush Makeup Products
Makeup Colours
A wide variety of airbrush makeup products are available, including everything from foundation to eye, cheek and lip colours. Some products are matte, while others have shimmer. There are even metallic colours available.
Airbrush makeup is formulated to pass through an airbrush gun, making it different to normal makeup products. This is because only very thin liquids with small pigment particles can successfully pass through the airbrush without clogging it up.
Several brands manufacture makeup specifically designed for using in an airbrushing. These include Airbase, Kett, Kryolan, Make Up For Ever, Dinair, and Temptu.
There are three main types of airbrush makeup:
- Alcohol-based – often used when creating temporary tattoos or body art.
- Silicone-based – creates a smooth application that lasts all day without fading. The skin is unable to break down this product due to the silicone. A silicone base is workable/moveable until it sets.
- Water-based – a breathable and long-lasting product, though it can eventually be affected by sweat and oil on the skin.
Cleaning the Airbrush
Specialist cleaning products are used to clean the airbrush between colours or at the end of a work session. Many cosmetic brands make cleaners, including the ones that manufacture the makeup products.
Ultimately, the right cleaner needs to be used for the type of makeup formulation used. For example, use a silicone cleaner after using silicone makeup products.
