Colloidal Oatmeal Skincare | A Derms Secret Ingredient

Oats are pretty damn tasty. And while they make for a scrumptious morning breakie, turns out they're also great for your skin.

Colloidal Oatmeal skincare uses a finely ground form of this readily available ingredient to treat dry, itchy, and inflamed conditions.

Sound too good to be true? It's not.

While skincare in Australia often uses creative botanicals, Colloidal Oatmeal quietly sits with scientific data and clinical trials to support its benefits. 

Dermatologist and founder of Spotlight on Skin, Julia Rhodes says, “it has been shown in clinical studies to have anti-inflammatory and antioxidant activity, and to improve skin hydration and skin barrier function.”

What is Colloidal Oatmeal? 

Colloidal Oatmeal is oats ground into a fine powder. The ingredient helps create smooth, effective skincare products – without losing any beneficial proteins, lipids or enzymes. Look for skincare in Australia that includes this super soothing ingredient.

Is Colloidal Oatmeal good for your skin? 

Short answer yes. Long answer – when incorporated into a skincare routine, Colloidal Oatmeal can;
• Help relieve irritated, dry, and itchy skin
• Provide hydration by preventing transepidermal water loss
• Soothe and calm inflamed skin
• Support a healthy microbiome
• Balance the pH of the skin barrier
• Build an occlusive barrier that protects your skin from harmful external factors.

Dermatologist Julia Rhodes says, “Colloidal Oatmeal has been used in the treatment of skin conditions for centuries,” and medical studies support anti-inflammatory claims to treat dry, irritated skin. In addition, Colloidal Oatmeal has antioxidant capabilities, can improve the skin barrier, and as a prebiotic, encourages good bacteria to thrive.

The main active substances in Colloidal Oatmeal that help soothe the skin are;
Beta-Glucan: This humectant helps skin hold onto water, aids the stimulation of collagen synthesis, and acts as an anti-inflammatory. It's also a prebiotic fibre that feeds good bac (bacteria).

 • Avenathramides: A potent antioxidant and anti-inflammatory compound that helps with dry skin and redness.

• Other antioxidants: Flavonoids, Phenolics, and Vitamin E provide antioxidant support by absorbing free radical damage.

• Starch: Acts as a moisturising humectant and creates a physical barrier on the skin.

Is Colloidal Oatmeal good for acne? 

Colloidal Oatmeal has oil-absorbing properties due to its physical state (particle size and granulometry). This makes it a natural antiseborrheic (oil reducing) ingredient. 

Dermatologist Julia Rhodes says, “it is particularly useful in the treatment of dry and/or inflamed skin and works well with most other ingredients used in skincare.”

Colloidal Oatmeal has proven to be a must-have ingredient to soothe inflammation that often comes with acne-prone skin. 

So, yes. Get that oat goodness on those little wee spots.

Colloidal Oatmeal skincare and the truth about probiotics 

You've probably heard that probiotics are wonderful for your gut health. Well, same goes for skin health. 

Microbiome skincare utilises specific ingredients to support healthy skin flora. And researchers look at different types of prebiotics and postbiotics that benefit the skin and help the bacterial ecosystem.

Prebiotic and probiotic skincare helps with redness, inflammation, blemishes, and breakouts.

To understand how this works, we must look at the difference between prebiotics, postbiotics, and probiotics.

Boring Without You, Skincare that talks. Girl with Acne pulling a funny face.
Probiotic skincare 

Probiotics are the good bacteria that live all over our body, in our gut and on our skin. However, probiotic skincare can be a wee bit complicated.

 If a company making skincare in Australia tells you they have probiotics in their formula, it is likely a run for the hill situation. Let me explain.

Most "probiotic skincare" is actually prebiotics or postbiotics. That is because probiotics are live bacteria, and the preservative in your product (designed to kill bacteria) will likely get rid of the goodies before you even open the jar.

Very few brands achieve genuine probiotic skincare. A brand we love that uses actual live probiotics in its formula is Unconditional. They successfully separate the live probiotic from other actives and preservatives right up until the point you apply it to your face.

Prebiotic skincare 

Prebiotics are usually fibres extracted from vegetables, fruits, honey, and Colloidal Oatmeal. These are food for bacteria and have created a category of prebiotic skincare. 

But not all prebiotics are created equal, and different bacteria with different enzymes break down prebiotics in varying ways. 

You want great prebiotics to help your good pre-existing bacteria. If they eat correctly, they should develop properly, leaving you with healthy bac-filled skin.

Postbiotic skincare 

Postbiotics help create the ideal environment for bacteria to thrive.

 Lactic Acid from Lactobacillus is one example of this and helps maintain the acidic pH of the skin. Microbiome skincare companies know this and use these ingredients to support the overall formula.

Colloidal Oatmeal prebiotics 

Colloidal Oatmeal is a commonly used ingredient in microbiome skincare. This is because Oatmeal is a source of prebiotic fibres (β-Glucan) and helps feed good bac on your skin. Good bacteria can do the following:

 • Balance your skin microbiome (more good bac, less bad bac)
• Provide additional support for acne-prone skin
• Improve factors that lead to dryness, redness, and dehydration.

Can Colloidal Oatmeal irritate skin?
Although Colloidal Oatmeal is proven to soothe irritated and dry skin, everyone's skin is different. It is possible to develop a rash or skin irritation. If this happens, discontinue use immediately.

Does Colloidal Oatmeal clog pores?
No, Colloidal Oatmeal's physical state and particle size make it beneficial for absorbing excess oil, while the high amount of antioxidants manages free radical damage.

Is Colloidal Oatmeal safe for those who are coeliac and gluten-free?
Yes, Colloidal Oatmeal is safe to use for those who are gluten intolerant and coeliac, and studies show that gluten-containing products are only a concern when ingested. However, like with all skincare, we recommend patch testing on your arm or hand before use.
