Aromatherapy Skincare Lemon Oil - How bright is your skin?

I've always been a fan of lemon oil as it's an excellent skin brightener and goes a long way towards making ageing skin looking less dull and mottled.


This is a view that qualified aromatherpist's share and lemon oil has been successfully used for many years to help brighten, lighten and even out skin pigmentation. 


I believe many people feel that it's great to know the capabilities of lemon oil, but would like more facts to substantiate these claims. 


This is the aim of this blog.



Firstly, we need to get to grips with why our skin may suffer from pigmentation.There are cells in our skin which are responsible for pigmentation. Often, as we get older, this pigmentation becomes more pronounced. These cells are called  melanocytes.
Melanocytes produce skin pigmentation (melanin) in two forms.
The darker skin creating pigment is called eumelanin, and the lighter skin creating pigment is called phaeomelanin. 
The amount of each type of skin pigment determines the colour and degree of  pigmentation in our skin.


To summarise so far, we all have body cells which create melanin which in turn shows as skin pigmentation to varying degrees.


The production of skin pigmentation, (melanin) is complex and works through various cells converting some of them to be able to produce melanin. The 'bit' that actually is responsible for this conversion is an enzyme called tyrosinase. 
You'll have seen the work of tyrosinase when you've peeled a potato and after a few minutes the potato turns brown. This enzyme (tyrosinase) activates when the potato is exposed to the oxygen in the air. If you type tyrosinase into your search engine you can find a lot more information if required.
With us humans it's the same process, when our skin is exposed to the air, our melanocyte cells get working so that skin pigmentation melanin is produced. 


This is important as the production of melanin protects our skin from the sun. Melanin absorbs harmful UV rays.  


To summarise again, we now know we've some cells in our body that create melanin which can show as skin pigmentation. Additionally we also know that this is important as it protects us from harmful UV rays.


So, we're in the position of understanding that our body is doing a fantastic job in protecting us from harmful UV rays, but many of us aren't so happy that our skin tone often looks uneven from the varying levels of melanin produced.
Therefore, if the amount of melanin is decreased, we should have less visible pigmentation on the skin. 


  • But how far do we go? 
  • When is it dangerous if we're not allowing the body to protect us as well as it could from harmful UV rays? 
  • Where do you draw the line between the look of our skin -V- it's protection?

How about turning the problem on its head though? Instead of looking at chemical ingredients to cut the production of melanin, why not create an environment where the body simply doesn't need to produce as much melanin?


Now it's getting very exciting.


Melanin has to be produced due to the skin's exposure to harmful free radicals of which some are produced by UV rays. As lemon essential oil is a phenominal anti-oxidant, the enzyme tyrosinase  doesn't have the same need to produce high levels of melanin to protect us from UV rays as the antioxidant properties in essential lemon oil partly takes over this role.

Applying high levels of anti-oxidants to the skin is very much an holisitc way to deal with problematic pigmentation.


Our final summary is:


  • we accept the production of melanin is crucial to protect us from UV rays
  • we often don't like the look of our uneven skin tone due to the pigmentation
  • we're not happy to interfere with the reduction of melanin 
  • we now understand a mighty dose of natural anti-oxidants is beneficial as they fight free radicals some of which are caused by UV rays
I'd advise anyone wishing to use products using pure essential oil of lemon to purchase products which have been formulated by a qualified aromatherapist as lemon can be a skin irritant if the correct dosage has not been adhered to. Additionally if your product contains lemon, please ensure adequate sunscreen protection is applied or even better, stay out of the sun.


INSKIN produce a wonderful - Anti-ageing Precious Facial Oil which contains the correct amount of pure essential lemon oil.


Many thanks for taking the time to read this blog, and if you've found it interesting I'd be delighted if you'd ask your friends to take a look.


In my next blog - I'll be considering "How cool is Vitamin A (Retinol)?"


Many thanks, hugs and kisses
