Dear Customer,

Thank you for reaching out to us, numbuzin!

Our products are formulated for all skin types and ages :)

However, the reaction of skin may differ depending on each skin condition, so if your daughter is beginner to our brand, we recommend her patch test for 48 hours. 

Patch test can be done by applying small amounts of each product onto inside of her arms or back of ears.

In case of No.3 toner and No.3 serum, they have Bifida and Galactomyces ferment which are key nutritious ingredients for skin texture and radiance.

If you have more questions or need further assistance, please let us know!

Thank you!

Best Regards,

numbuzin customer support
