Astringent products, their role on the skin

Does your skin react to just about everything?

Or maybe your an oily skin guy or gal and just find it hard to control that daily shine and have resorted to using harsh ingredients in the past.

For this reason I want to discuss astringent ingredients, that are often used in the beauty industry.

The word astringent is such an ambiguous word, what does it really mean?

An astringent is a substance, which causes biological tissue to contract or draw together, after topical application.

Bare with me as I get technical for a minute; astringents work on the protein keratin found in the skin, the salt bonds in keratin are affected by temperature and pH, these bonds form when the skin is slightly acidic or cool.

If the bonds break the keratin molecules separate, causing the outer layer of skin to swell. When the skin cools these salt bonds reform,and it is this process that produces the temporary toning effect associated with astringents.

Can you permanently reduce pore size?
No! apologies for being blunt here, but contrary to popular belief, this action is short lived.

You can’t permanently reduce enlarged pores, which are over stretched, no matter what clever marketing campaigns try to tell you; This is a topic I discuss in greater detail, in the article oily skin remedies.

Alcohol Astringents
Two alcohol astringents are used in the personal care industry:

  • Isopropyl alcohol, often referred to as rubbing alcohol
  • SD alcohol or ethanol, is a specially denatured ethyl alcohol

Astringents, give the skin an instant cooling effect.

They stimulate the sensory nerve endings and constrict blood vessels, when you apply alcohol on the skin it evaporates really quickly.

It is this action that gives it the cooling feeling much like splashing cold water on your face; this is why alcohols are often used in after shave products.

Synthetic versus natural astringents

Synthetic alcohols can cause irritation and dehydration.

This upsets the delicate micro flora that preserves the acid mantle; this is where alcohols get their reputation for stripping the skin.

And yes they do clear the skins surface of oil but at a price; they cause oil glands to go into overdrive as they try to replace the lost oil, making skin even oilier…

So no matter what your skin type try to avoid astringent alcohols, fortunately there are plenty of natural alternatives available.

Natural Astringents

  • Sage
  • Menthol
  • Camphor
  • Witch hazel
  • Lemon extract
  • Potassium alum

Witch hazel is often used as a natural alternative, but used in high concentrations it can be very astringent,when used in low concentrations it can be extremely soothing, making it the perfect natural treatment for an oily, combination skin prone to breakouts.

Because we are all about treating sensitivity our formulas are extremely repairing. Savior is a gorgeous unique serum that calms and soothes that can be used alone or layered with bio lipid comple  perfect for treating a skin that has become compromised.

    Hi Samantha
    Are you saying , that it is actually not possible to permanently shrink pores? I feel I have to challenge this statement because so many skincare companies actually claim that you can… Why would you say other wise??

      Hi Jen

      I am sorry to be the one to tell you, but yes it is impossible to permanently shrink pores. A product that has this claim behind it, will usually contain an astringent ingredient that temporarily shrinks the pores, because it is irritating and the pore closes down. it is possible to absorb excess sebum from the pores but nothing permanent will reduce pore size which is due to genetics or overstretching due to over secretion from the sebaceous glands.

    Hi Jen I almost have to agree with you, almost because I have been using astringent products on my open pores for many years but nothing has ever reduced them in size..frustrating to say the least 6

    Pores are stretched by the over production of oil in the sebaceous gland and Samantha is right nothing will shrink the pores sorry to say.

    Hello.
    I like your blog. Very interesting. Thank you!

    I’m not sure if this question really suits this particular blog entry.. but anyway.. I’ve seen a lot of DIY projects on the internet of how to make natural facial toner. And this includes two ingredients : water and apple cider vinegar. What do you think about this type of toner? Can this cause any harm to skin?

    Would be interesting to hear your opinion.
