Beauty from within

Oliglow® provides food-based prebiotics concentrated to 70% galactooligosaccharides, including 9% 4’-galactosyllactose.
Oliglow® offers clinically proven benefits on skin: an increase of hydration through an improvement of the barrier function of the skin and higher protection against photo-aging are scientifically proven. 2 g/day.

Characterization of the active compounds

Oliglow® is a food-based ingredient concentrated to 70% galactooligosaccharides (GOS), including 9% 4’-galactosyllactose (GL), a specific prebiotic originally isolated from mother’s milk. These soluble short-chain fibers are non-digestible and ferment in the intestine, where they contribute to a regulation of the local microflora for a healthier microbiome.


GOS       > 70%
4’-GL   > 9%


Recommended daily dosage: 2000 mg

Gut-skin axis: it all starts from microbiome

Oliglow® has demonstrated its benefits in rebalancing the ratio of Lactobacillus and Bifidobacteria of the gut microflora, leading to lower inflammation and oxidative stress, both of which are damaging to skin health.

Science supporting Oliglow®

The benefits of Oliglow® on skin health have been demonstrated in a clinical study compliant with the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use  (ICH).

Double-blind, randomized, placebo-controlled study

Usual lifestyle & diet
  • Skin barrier function
  • Skin sensitivity to photo-aging

Skin barrier function - hydration

Oliglow® improves the capacity of the skin to retain water, significantly  improving the level of hydration of the upper layers of the epidermis.

Skin sensitivity to photo-aging

The decrease in erythema demonstrates a lower level of skin irritation, while a significant reduction of the melanin index demonstrates a lower sensitivity to sun damage. 


  • Rebalances the microbiome for a healthier skin
  • Reinforces the barrier function of the skin
  • Increases hydration of the upper layers of the epidermis
  • Decreases redness and irritation of the upper layers of the epidermis
  • Decreases photo-sensibility of the skin
