Are probiotics effective against acne?

The potential of probiotics for treating acne vulgaris. We hear more and more about the benefits of probiotics, especially on our digestion and our immune system. Do they also have an impact on acne?

Probiotics for Acne & Skin Health

Are probiotics effective against acne?

What are probiotics?

The term "probiotics" includes microorganisms, including good bacteria and yeasts, and they are present in the different microbiota of the body, such as the intestinal, oral, or skin microbiota.
They feed on prebiotics, a type of fiber found in certain foods. Above all, they play a protective role by limiting microbial attacks and inhibiting their activity.

They make sure always to maintain the balance between good and bad bacteria.

At the same time, they strengthen immunity and the barrier function of the mucous membranes.
Probiotics are best known for their benefits on the digestive system. Indeed, they facilitate digestion, regulate transit and relieve dyspepsia. Studies also show their interest in weight loss.
Researchers are also interested in the role of probiotics on the skin, and these balance and enrich the skin microbiota.
In addition, they protect the skin by strengthening the barrier function and boosting its natural immunity.
Finally, they reduce inflammation often associated with skin diseases such as dermatitis, psoriasis, or acne.
Thus, consuming probiotics would be interesting to improve the beauty of the skin and reduce acne and its symptoms: pimples, blackheads, excess sebum.
We prefer fermented products such as yogurts, brewer's yeast, or kefir. They are also available in food supplements (capsules or powder).

The balance and enrich the skin microbiota.

These microorganisms have a double action on the skin microbiota.
On the one hand, they maintain the balance between the good and the bad bacteria there. Thus, the former must always be in excess. Otherwise, this imbalance promotes skin conditions such as atopic eczema or acne.
On the other hand, they support the microbial flora already in place and enrich the microbiota. They can increase the populations of beneficial bacteria, thereby improving the skin microbiota composition.
This review shows the potential of probiotics in the treatment of acne. Staphylococcus epidermidis and Lactococcus strains appear to be effective against Cutibacterium acnes, the bacteria responsible for acne.

Probiotics protect and strengthen the skin.

Probiotics strengthen the skin barrier located at the level of the epidermis. Acne is often associated with an alteration of this protective "shield." Indeed, it is less efficient and protects the skin less well against external aggressions.
Weakened, it responds with hyperseborrhoea (excessive secretion of sebum) and the appearance of imperfections. Skin that defends itself well is, therefore, less prone to acne.
Finally, probiotics boost skin immunity and boost the natural defenses of the skin, which fight against pathogenic germs. In addition, they modulate the immune reaction to limit rashes and acne breakouts.

This study shows the impact of probiotics on the skin microbiota and on the immune system to fight against skin diseases.

Probiotics reduce skin inflammation

These microorganisms are interesting in the case of inflammatory acne. Indeed, they are excellent natural anti-inflammatories.
Probiotics can reduce skin inflammation. For this, they inhibit the production of pro-inflammatory cytokines such as interleukins, which aggravate skin diseases, including acne.
Reducing inflammation soothes discomfort (red, swollen, and hot lesions) and limits imperfections: papules, pustules, comedones. Acne is less severe, and rashes are less frequent.
This study shows the anti-inflammatory action of probiotics and their beneficial effect on skin diseases.
