The first bacteria make the difference.
At birth, the development of the skin microbiome begins: a living protective layer of good bacteria. During the first months of life, this ecosystem evolves rapidly, and the skin learns to better protect itself against external influences. Therefore, baby skin deserves care that supports this natural process instead of disrupting it.
Daily habits, such as washing with traditional products, can wash away that protective layer. The results are seen later: dry skin, red diaper rash, and skin that reacts to everything.
- Protective layer is compromised
- Microbiome weakens
- Dry skin, rashes, and reactions return
Probiotherapy respects the skin’s natural protection and supports it where necessary. Instead of washing away, we add.

- Protective layer remains intact
- Microbiome is strengthened
- Skin that is calmer and less reactive
Visible difference in less than a week.
The BBY PROBIOTIC REPAIR Diaper Cream actively restores and strengthens the microbiome. Colloidal oatmeal soothes redness, while the protective formula shields the skin from moisture and friction. The live bacteria in the formula form a strong shield and help your baby’s skin recover in 1, 2, 3. They may be invisible to the naked eye, but the result is not.
Gentle on the skin.
The skin microbiome keeps the skin supple, wards off pathogens, and helps train the immune system. The stronger that natural protective layer, the less likely the skin is to dry out or become irritated.
Baby skin is thinner and more fragile than adult skin. It dries out faster, and its natural protection is still fully developing.
That is why it needs care that not only feels gentle but also respects its skin microbiome. BBY supports the skin exactly when it needs it: during cleansing, care, and recovery.
Gentle cleansing
Removing impurities without drying out the skin or disrupting its natural balance.

Which products should I use?
Every skin is different. But one thing holds true for everyone: healthy skin starts with a healthy microbiome.
Choose daily care to protect the skin, or targeted help for redness and diaper rash.
