First of all, we need to understand this thing called the Acid Mantle.
Acid Mantle is the thin, slightly acidic film on the surface of our skin. It is made up of our oil + sebum. it's purpose is to act as a barrier to bacteria, viruses and other potential contaminants that tries to penetrate our skin. Due to its slight acidity, this Acid Mantle helps to neutralise the chemical effects of these contaminants as they are primarily alkaline.
This is why babies to infants and even to children are not advised to use special cleansers to clean their faces. Many times the reason we give is because they are still young. But really, we need to know that we are created in a very amazing way where this Acid Mantle is like a God given protection for our skin.
Then what happens when we enter our puberty years? The food we eat, the stress in school, hormonal changes and imbalance causes this Acid Mantle to be imbalance due to the unequal amount of oil and sebum being produced at different parts of our faces. Very often you hear people will say T-zone oily. That is because our T-zone have got more oil glands compared to our cheeks and neck area.
When you cleanse your face,
you are literally removing this layer of Acid Mantle together with the impurities you feel on your skin. Meaning, your skin will be left 'bare'... unprotected... Therefore, if you wash your face with a good cleanser and do not apply any toner or moisturiser, then i would say that your skin is are a worse or dangerous state. Then it would have been better that you did not wash your face at all.
How harmful are the dirt on your face (When you have your Acid Mantle)? Less harmful than the contaminants that can penetrate your face when the Acid Mantle is being removed.
How long does it take for the new layer Acid Mantle to build up? It takes 4 hours before this natural defence is being built up again.
What is the purpose of a moisturiser? Moisturisers are meant to 'act-as' an Acid Mantle to your skin immediately after you wash your face. To protect your skin from bacteria, viruses and other potential contaminants that tries to penetrate our skin.
What about the different kind of moisturisers? I will explain that in my future post on moisturisers so stay tune. :)
In conclusion, cleanse or not cleanse? If you will be diligent to apply moisturisers, YES please cleanse you face with a good cleanser that suits your skin! But if you are too lazy to apply moisturisers or do not have a moisturiser that is suitable for your skin, then it is better for you to have not cleanse your face.
My next post will be on what are the different kinds of cleansers and how to identify which is for you. :)
