A Guide to Exfoliation for Smoother, Brighter & Glowier Skin

*Originally published at The Sheet Mask Shop by Jess

“I’ve been noticing an increasing interest in exfoliating acids lately, and a lot of lovely ladies asking for advice about them and exfoliation in general. As someone who loves exfoliation and how it makes my skin feel, I certainly understand the excitement! I also, however, have skin that can easily become over-exfoliated. I am also very aware that exfoliation products can be confusing – there are many different types to choose from, and some may suit certain skin types better than others. So today I thought I’d help try to explain some of the ins and outs of exfoliation for you, with some specific recommendations included for different needs and skin types. If you’d like a more detailed post on any of the specifics, or simply want to ask a question or 5 – please don’t hesitate to say hi via my blog or Instagram“.

Why is exfoliation great? I love exfoliation for the same reason I love sheet masking – it has an immediate effect! Exfoliators help remove the dead skin cells (and debris) that build up on the skin’s surface, and removing dead skin cells has a lot of benefits for all skin types. A build-up of dead skin cells can make the skin’s texture rough, dry and uneven. Dead skin cells that build up in pores can clog them, making pores appear larger and causing breakouts and bumps that can become acne. Dead skin cells also tend to dull the skin and can make fine lines and wrinkles more obvious.

Using the right exfoliators to remove these dead skin cells reveals younger skin cells and assists the skin to look and feel smoother, softer and glowier. It can keep pores clear, reduce acne discolouration and uneven skin tone, and even help fade sun spots and pigmentation. Exfoliation also helps your other products (sheet masks, serums, essences and creams) work better as those dead skin cells can act as a barrier reducing the ability of your skin care from penetrating your skin, so removing them helps your other products get to work in your skin more easily.

What are the different types of exfoliation? There are a few different types of exfoliants used in skin care, with the most common being acids, enzymes and manual exfoliators (i.e. scrubs/granules). Let’s break them down:

ACIDS

There are a few different types of acids generally used to aid exfoliation, in AHAs, BHAs and (the newer) PHAs. All of them work by lowering the skin’s pH and dissolving the bonds, or “glue”, that holds the cells of dead skin together – making them easier to remove or shed naturally more quickly. These acids can be used in different types of skin care products – including cleansers, toners, essences, serums and creams (and some sheet masks!). I like to use acids as early in my skin care routine as possible, when the skin’s pH is lower, as it helps them work more effectively. I also tend to prefer acids in cleansers, toners, peeling masks and essences that can be used during, or immediately after cleansing. But what acid is right for you?

  • AHAs are alpha hydroxy acids and include lactic, glycolic and malic acids. These acids are water soluble and great for breaking down dry, dull, surface dead skin cells. They are particularly good for helping reduce pigmentation, rough skin and uneven skin tone.
  • BHAs are beta hydroxy acids, and include salicylic acid and betaine salicylate. These acids are oil-based and can penetrate into pores to break down dead cells that clog them – leading to blackheads and acne, and larger-looking pores. These are particularly good for oily, acne-prone and congested skin types.
  • PHAs are poly hydroxy acids (a new forms of alpha hydroxy acids with a larger molecular size), and they include lactobionic acid and gluconolactone. Because PHAs are larger molecules than the traditional AHAs, they can’t penetrate into the skin very far and work towards the skin’s surface, whilst also being natural humectants that draw water to the skin, increasing its hydration. They are a great alternative to AHAs for sensitive skin types and many people can use them more often.

When might acids not be right for you? Because acids chemically dissolve cell bonds, and penetrate the skin to varying degrees, you can easily overdo their use. It is important that you start slow, and pay attention to your skin to determine how often you can use these products. If you are pregnant, you may be advised not to use BHAs (or retinol) during your pregnancy but most importantly, acids (and retinoid products) can make your skin more sensitive and susceptible to sun damage. While you really should use a sunscreen every day anyway, it is really imperative that you actially make it a daily part of your routine when using acids. If you can’t trust yourself to do this, it may be better to start with one of the other exfoliants below. Personally, I don’t like using acids for body exfoliation – because while I wear sunscreen on my face religiously, I am less trustworthy with other parts of my body!

ENZYMES

Enzyme exfoliators work slightly differently to acids. These products break down the proteins in dead skin cells to help them shed more easily. Enzyme exfoliators are generally fruit derived, especially from pineapple and pawpaw. They are good for more sensitive skin types, and very unlikely to irritate, as they work only on the skin’s surface. They are usually water-activated (eg. an enzyme wash), and can help all skin types, being a great option for those whose skin cannot tolerate acids (or can’t be trusted to wear sunscreen every day).

MANUAL EXFOLIATORS

While acids and enzymes break down the structure of dead skin cells, manual exfoliators actually work to lift off and remove them. A scrub with a face cloth or brush (eg. a Clarisonic Mia or Foreo Luna) can act as a manual exfoliation. But personally I love well formulated, very gentle scrubs for manual exfoliation, to ensure I am actually removing the skin cells that are being broken down by my acid or enzyme exfoliants. It is also by far my preferred body exfoliation method. The important thing to remember with scrubs is very gentle pressure only. You don’t want to overly tug or rub at your skin. Very fine particle peeling masks can be excellent for sensitive skin, or those already using acids. Scrubs are also a great option for younger skin, sensitive skin or those that cannot tolerate acids, or regularly apply sunscreen.

How often should you exfoliate? All skin is different. Gentle acid toners may be able to be used daily, or every second day. However, peeling masks, scrubs and stronger acids are ideal to be used once or twice a per week within your established skincare routine. My advice is to start slow and see what your skin likes best. Most of all, if you can, exfoliate early in your skin care routine to ensure that the product can work as effectively as possible – and help prepare your skin for your treatment skin care products so they absorb as effectively as possible. I personally love to time my exfoliation days with treatment sheet mask nights!
