Using latex and ageing the skin and hands

Being the first time I had worked with latex and any kind of special affects I was quite nervous and didn't know how to approach it as I am quite a perfectionist and it frustrates me when what I am creating doesn't go how I expect.
Originally I tried to put the latex on my model's forehead as there more skin and wrinkles to work with. However it didn't really go to plan as I think i worked the latex into too much which meant it dried too quite and didn't pick up any wrinkles or natural creases.
As my first attempt didn't go to plan I moved on to the outer corner of the eye as there are more natural creases there like when you smile.
Using latex you have to prep the skin and also have to test the model first to ensure they are not allergic.
To ensure the skins natural creases get picked up by the latex you have to stretch the skin whilst applying the latex then by using a hair dryer on cold you dry the latex until it goes clear. Once it goes clear you would see the natural creases in the skin.
With this I feel that I struggled to create an aged affect due to the area I chose to test it on as when I stretched the skin to apply then released it there wasn't many wrinkles. However I still feel that I was able to get some kind of visible effect. This is useful to know as it helps you realise that all skins types are different and you need to consider that before choosing a model and might want to test it out before hand to ensure that it looks as effective as you want it to.

Health and safety
When using products you haven't used before like latex it is important to test a small patch on the model to ensure that the area you need to apply it to properly doesn't have a bad reaction to it. As using it around the eyes or on the face can be risky as it is such a sensitive area.
