Postbiotic cream for acne-prone skin: rebalancing the microbiome to soothe blemishes
Acne-prone skin is not just “oily” skin that produces too much sebum. Today, dermatological research is highlighting a key factor: imbalance in the skin microbiome, All the micro-organisms that live on the surface of our skin.
When this microbiome becomes depleted or unstable, the skin reacts: redness, inflammatory pimples, excess sebum, discomfort, hypersensitivity, persistent scars...
The postbiotics offer a new, more respectful and intelligent approach to help skin rebalance itself over the long term.
Microbiome & acne: when imbalance sets in
The skin microbiome is made up of “friendly” bacteria that protect, soothe and support our skin barrier.
When it is disrupted by stress, hormones, pollution, certain cosmetics or stripping routines, it produces :
overproduction of sebum
local inflammation
damage to the skin barrier
proliferation of C. acnes (bacteria associated with acne lesions)
greater sensitivity
This vicious circle makes imperfections worse rather than better.
Postbiotics, probiotics, prebiotics: what's the difference?
To understand the benefits of a post-biotic cream, it is useful to distinguish between the three families:
| Assets | Role |
|---|---|
| Probiotics | living micro-organisms useful to the microbiome |
| Prebiotics | nutrients that feed these micro-organisms |
| Postbiotics | active metabolites from fermentation that send beneficial signals to the skin |
The postbiotics are particularly interesting:
✔ they're not alive → no instability
✔ efficiency targeted and measurable
✔ very well tolerated
✔ biomimetics the skin's natural mechanisms
Why a postbiotic cream is ideal for acne-prone skin
Postbiotics act on 3 known causes of acne :
1. Seboregulation
Reduces excess sebum without stripping, Unlike some acid treatments.
2. Anti-inflammation
Reduces visible redness and inflammatory reactions.
3. Reinforced skin barrier
Balanced skin heals better and marks less.
As a result :
✔ fewer inflammatory pimples
✔ less shine
✔ more comfortable skin
✔ refined skin texture
✔ better overall tolerance
