Making the skin taught, or stretching the skin, while you are waxing makes for an easier and less painful process, and also helps reduce post-wax complications, like bruising.
In most cases, the wax sticks to the skin, especially soft wax. Removing the wax while it is stuck to the skin will detach the skin layers from their underlying support tissues and very tiny blood vessels associated with it. Blood moves out of broken blood vessels in between the cells and turns into bruising.
Older clients have thinner skin and more fragile blood vessels, making them more prone to bruising and other complications of waxing. For those groups of clients, stretching the skin is even more important.
With any waxing treatment, some small vessels break microscopically anyway and are not noticeable in most cases, but if there is a blood disorder, like hemophilia, or the client is taking blood thinners, like aspirin or heparin, the blood may not easily clot, leading to a higher chance of bruising and complications.
If your client has any medical condition or is taking medication, you must have written permission from a doctor to do the service. But even with a written doctor’s permission, you should not treat this client in the same way as other customers. You need to use your best judgment and treat the client accordingly. For instance, for someone who is on blood thinners, you may need to consider the following precaution: use smaller patches of wax so you can hold the skin, make the skin taut in all areas of the body, use the type of wax that doesn’t stick to the skin, like hard wax, or suggest sugaring instead of waxing.
The areas of the skin that have less or looser underlying supports and cushion, like eyebrows, testes, and labia, over tendons and joints are more prone to pain and complications.
Stretching the skin on loose skin areas like the labia, tastes, penis, and eyebrows not only prevents bruising and other complications, but also distracts the client from the waxing treatment, especially if it is done by the clients. It is always a good idea to involve your client in the treatment process.
