How Your Skin’s Microbiome Could Support Mental Wellbeing


You care for your skin every day. But what if your skincare could help your mood too?

Recent research from Unilever shows this may be possible. They linked higher levels of Cutibacterium bacteria on the skin to lower stress and better mood. That means your skin microbiome isn’t just about acne or hydration—it can reflect how you feel.

What They Did

Unilever tested microbiome samples from the face, scalp, forearm, and underarm. They paired this with mental well-being surveys. They found consistent associations: more Cutibacterium bacteria meant less stress, especially on the face and underarm.

Lab Insights

In lab models, topical application of skin microbes influenced cortisol release. This shows a direct link: microbes on your skin can affect stress hormones.

Toward Psycho‑Dermaceuticals

The idea of “psycho‑dermaceuticals” is emerging. These would be skincare products that:
  • Use live probiotic strains or microbial metabolites
  • Target cortisol and mood regulation
  • Fit into your daily routine
Early trials show promise: users report lower stress and better sleep after four weeks of probiotic serums.

What You Can Do Now

While we wait for next‑gen products, here’s how to support your skin‑mind connection:
  • Choose gentle, pH‑balanced cleansers. Avoid harsh antibacterials that strip your microbiome.
  • Incorporate prebiotics. Ingredients like plant-derived prebiotics and niacinamide feed good bacteria.
  • Prioritise self‑care habits. Balanced meals, quality sleep, and breathing exercises support both your skin and mindset.
 Questions to Consider
  • How personalised should probiotic skincare be?
  • Who owns your microbiome data?
  • Could long‑term use create microbial imbalances?
Brands and researchers need to address these. That means transparent trials, clear data settings, and easy education.

What’s Next

The future is here: treatments allow a prebiotic serum to improve your skin health and resilience and to help you feel calmer while you hydrate, you’ll treat both skin and stress in one swipe.

We’re moving into skincare that acknowledges your skin as both surface and signal. Your routine becomes more than a ritual; it becomes part of your wellness toolkit. That means looking for smart products, asking thoughtful questions, and advocating for safe science.

Your skin can do more than look good. It can help you feel good.

What is the difference between a beautician, beauty therapist, esthetician, aesthetician and dermal therapist?

Beautician, beauty therapist, esthetician, aesthetician, dermal therapist - what do all these mean? These terms are different in various countries whether you are in Australia, Europe, Asia or the US. I will try and explain the terms as they are used in Australia. Beautician BEAUTICIAN  Certificate III in Beauty Services (3-6 month study) Beauticians can be trained on the job by their peers with no formal qualification or training. Some beauticians, however go to TAFE and have a Certificate III in beauty treatments. Beauticians mostly perform beauty services such as spray tanning, waxing, tinting, nails enhancements, express pedicures, makeup and lash extensions.

Is Micro Needling Better Than Chemical Peels?

Image
One of my students sent me this question:  "Do you feel that needling is better than chemical peels?" I thought it's an excellent question because, because with so many people talking about these skin rejuvenating treatments, it can be quite confusing.  Micro-needling and chemical peels are two different modalities used for various purposes. It's like comparing apples to bread. Not everyone needs micro-needling, and not everyone is a suitable candidate for chemical peels. What Is Micro-needling or Dermarolling?  Micro-needling, skin needling (or dermal rolling) was used initially as a clinical treatment for improving and reducing post-acne scarring. It works by breaking down existing scarred tissues with fine needles which stimulate the skin healing and rejuvenating process. Over the past few years, it has become a popular modality for reducing the appearance of aging, lines, wrinkles and tightening the skin. The process is called Collagen Induction ...

CONGESTION: a cluster of small, deep, skin coloured, painless, stubborn lumps / bumps on the skin

Image
Congestion can be a stubborn problem to clear, it can linger and be a real nuisance. In oil related congestion, the sebum is thick and waxy and has settled deep down in the hair follicle. Usually found around the chin and cheeks, it feels like a cluster of small, deep lumps under the skin. Congestion is usually skin colored , is not painful and does not itch. Once it appears, it usually just sits there and does not clear on its own. The waxy sebum can be a result of poor nutrition, certain food intolerance, a sluggish metabolism, hormones,  not drinking enough water, etc. and  if left untreated, can potentially lead to ruptured follicles, papules and painful lesions or acne.  To clear it, the waxy sebum has to be broken down, liquefied , and allowed to flow freely to the surface.  If congestion occurs around the jawline and cheeks, and occasionally on the neck, then it is either caused by over nourishing products or it's an internal problem, where the bod...
