I recently tried out a whole bunch of different wipes when I got my eyebrows microbladed (review coming soon) and couldn’t wash my face for a week. I generally prefer a proper cleanse to wipes because it feels less wasteful and polluting, but I do find them handy when travelling, and in situations like these! I tried wipes from Bioderma,Philosophy, Neutrogena, Wotnot Naturals and Burt’s Bees They all tested at a skin-friendly pH 4-5. Here’s what I thought of the individual products.
Bioderma Sensibio H2O Wipes
Bioderma Sensibio Micellar Water is a huge hit in Australia, so there’s been a lot of buzz around their new Bioderma Sensibio H2O Wipes ($20.99 for a pack of 25) too.
The Sensibio line is designed for sensitive skin, and these wipes have a very short ingredients list which is good if you need to scan for your specific allergens. I thought it would be just the micellar water in wipe form, but it’s a completely separate product: the surfactant in the wipes is polysorbate 20, while the micellar water contains PEG-6 caprylic/capric glycerides.
I found these a bit of a mixed bag. They didn’t sting my eyes, but they were a little weak in the make-up removal department. My skin felt a bit tight after cleansing with these, but paradoxically it still felt plump and hydrated with that slightly sticky humectant feeling. The regular Micellar Water works better overall in my opinion, although these are a bit more convenient. It has a stronger fragrance than the micellar water as well.
(This is probably a good time to mention my pet hate – when people write H20 (with the number zero) instead of H2O (with the letter O). H2O is the formula for water and means 2 hydrogens + 1 oxygen, H20 is twenty hydrogens bonded together against the laws of physics. I know it’s a super petty thing to get irritated by, but I needed to get that out of my system.)
Philosophy Purity Made Simple cleansing cloths ($18 AUD for a pack of 30) are notable because unlike most other wipes, they don’t contain a standard surfactant in the top ingredients – there’s solvents (butylene glycol and water), oils (meadowfoam seed oil is the main one) and gluconolactone (a PHA exfoliant).
Your skin is covered in a thin protective layer of dead cells (the stratum corneum) which naturally shed over time in a process called desquamation. Sometimes this layer gets too thick, resulting in dull, rough skin. Exfoliants help the shedding along, resulting in more even, “glowier” skin.
What’s chemical exfoliation?
Chemical exfoliants help cells shed in a more indirect way than physical exfoliation, which works using friction between the tool or scrub and the skin. The mechanism of how chemical exfoliants work aren’t always obvious, but the most common theories and methods of how they work are:
by normalising cell turnover – that is, how quickly cells in the epidermis die and migrate to the stratum corneum, pushing old cells out. Exfoliants do this by travelling to living cells under the dead layer and telling them to change how they behave – in more technical terms, they act on receptors to upregulate cell division. (Technically, any ingredient that does this is a drug, but regulations around these “cosmeceuticals” is pretty iffy.)
by unsticking the cellular glue (desmosomes) holding dead cells together in the stratum corneum.
Chemical exfoliation is touted to be gentler than physical exfoliation, mostly because it’s less prone to user error. However, how well it works depends largely on the formulation of the product. A poorly formulated product might not work, or it might work so well that it irritates your skin and causes uneven pigmentation and chemical burns.
Hydroxy acids are the most common ingredients in chemical exfoliants. There are two main types:
Alpha hydroxy acids (AHAs), which includes ingredients like glycolic acid, lactic acid, malic acid and mandelic acid. Glycolic and lactic acids are most common in skincare, and the vast majority of scientific studies on AHAs are based on the action of glycolic acid.
Beta hydroxy acids (BHAs), of which salicylic acid is the only one commonly used in skincare (I’ll be using the terms “BHA” and “salicylic acid” interchangeably).
A few ingredients are technically both alpha and beta hydroxy acids such as citric acid, which acts more like an AHA.
It’s not 100% clear how AHAs and BHAs work to exfoliate the skin – it’s likely to be a combination of the two actions described at the beginning: increasing cell turnover at the epidermis and unsticking stratum corneum cells. As well as just removing build-up of skin, they can also improve hyperpigmentation and reduce the appearance of wrinkles.
There are a few key differences between AHAs and BHA/salicylic acid:
Solubility: The commonly used AHAs (glycolic acid, lactic acid) are water soluble, while salicylic acid is oil soluble. Theoretically this means salicylic acid is better for treating oily skin and clogged pores because they can penetrate through sebum and sebum plugs, but there’s a lot of variation between people’s experiences. You’ll generally find AHAs in products for dry, ageing skin, and BHA in products for oily, acne-prone skin.
Sun sensitivity: Glycolic acid is documentedto causesun sensitivity for a while even after you finish using it, while salicylic acid isn’t. Salicylic acid has a UV protective effect while on the skin, due to the benzene ring in its structure which lets it act as a chemical sunscreen. You need to wear sunscreen while you use alpha hydroxy acids, and for at least a week after you finish – otherwise, you can actually cause more wrinkles and uneven pigmentation and sagginess than you started off with! And you should use sunscreen with salicylic acid anyway.
Other effects: Salicylic acid can have some anti-inflammatory action, depending on whether enough gets through the skin – it’s actually one of the active forms of aspirin. Glycolic and lactic acids are humectants that act to slow down the evaporation of water from the skin.
Are you confused about how to choose the right exfoliation method for your skincare routine? This three-part series rounds up all the types of exfoliants for your face, with examples of products and their pros and cons!
This post covers all the physical exfoliation options. Part 2 will be on chemical exfoliation, and Part 3 will be a guide on how to choose the one(s) that will work for you. For a more barebones overview, check out this exfoliation basics post.
What is exfoliation?
Your skin consists of living skin (the epidermis), covered in a 15-20 layers of dead cells (the stratum corneum). The dead cells in the stratum corneum have an important role in protecting your living tissue from the outside environment. They’re completely replaced around every 2 weeks – the cells at the surface are constantly shedding. However, the shedding isn’t always regular, and sometimes it happens slower than it should. This leads to your skin being covered by too thick a layer of dead cells, which looks dull, uneven, scaly and flaky. Exfoliation helps the shedding along, ideally without compromising the ability of the stratum corneum to act as a barrier.
There are 2 main categories of exfoliation: physical and chemical. I’m including exfoliation tools under the banner of physical exfoliation, and enzymes in the chemical group.
What Is Physical Exfoliation?
Dead cells are buffed away mechanically using grainy products or tools. It’s a lot like sandpapering a block of wood or scrubbing tiles – the friction from rubbing an object back and forth over the skin lifts stuck cells.
Much like sandpapering wood, the harshness of physical exfoliation depends on a few factors:
what the exfoliating objects are like (how large, how hard, how smooth)
how you move them over your skin (how hard you press, what direction you go in, how long you rub it in for)
I personally find that rubbing lightly in small circles for a minute or two is more effective and less irritating than rubbing hard for a short period, with any physical exfoliation method.
Physical exfoliation has a reputation for being harsh, but I think it’s unfair – it can be very gentle, but most people use physical exfoliants way too frequently, and feel like it’s not working if they don’t feel raw and tingly afterwards. Don’t fall into this trap! It’ll make your skin worse in the long run, reducing the ability of the stratum corneum to act as a barrier against the outside world and prevent moisture from leaving (its barrier function).
These round beads are made of plastic and come in every imaginable colour. They used to be in tons of products because they’re really cheap and smoothly shaped, so they were budget-friendly and gentle on the skin.
However, it turned out that microbeads were an environmental pollutant – they made their way through the sewage system and into waterways, where environmental toxins (actual toxins) like pesticides latched onto them. When aquatic animals ate them, they would release the toxins. Nasty! (You can read more on microbead pollution on this post.)
Plastic microbeads were banned in a handful of US states after research showed that the beads were turning up everywhere. The Netherlands are in the process of phasing them out. Other Western countries are moving in this direction, so plastic microbeads are found in less products these days.
You’ll see them listed on the ingredients list as:
polyethylene
polypropylene
nylon-6
nylon-11
polymethyl methacrylate
You can find lists of microbead-containing and microbead-free products in your country on Beat the Microbead.
How to use
These are the standard scrub products – squeeze some into your hand, slap it on your clean face and rub around, then rinse.
Examples
It’s actually been quite difficult to locate plastic microbeads in my skincare collection – I only managed to find an old tube of Nivea Pure Effect All-in-1 Multi Action Cleanser, and a couple of Asian products (Muji Scrub Face Soap and Missha Cacao &Cream Facial Scrub).
There are lots of replacements for plastic microbeads available now, so you can still get your scrub on without as much guilt.
Jojoba Beads
One of the most popular replacements for plastic microbeads are jojoba beads. They’re made of chemicallyprocessed jojoba oil (the same process used to make solid margarine from liquid vegetable oil), and are usually listed as “hydrogenated jojoba oil” or “jojoba esters” in the ingredients list. These beads are translucent white, and they’re usually found in products as very fine grains.
How to use
Just like microbeads, these are straightforward scrubs. Rub them onto clean damp skin, rinse away afterwards.
Examples
These are particularly popular in products marketed as natural – they show up in Jurlique, Moreishand Neutrogena Naturals scrubs, as well as a Guinot Gentle Face Exfoliating Cream, a scrub/peeling gel hybrid. They’re popular but I’m personally not that fond of how they feel on my skin, so I don’t reach for these that often.
