How long should you keep IN’OYA products before opening them ?

It is possible to keep an IN’OYA product for up to 30 months between the date of purchase and first use. Most of our formulas have a proven stability of more than 30 months guaranteeing their effectiveness and especially guaranteeing the absence of side effects.

How long should you keep IN’OYA products once opened ?

IN’OYA products undergo stringent testing which allow us to evaluate the maximum storage durability in the same conditions as the products are generally used in (humid atmosphere of the bathroom, ambient heat...). Once the packaging is open, usage up to 6 months is recommended. The usage duration after opening of each product is mentioned on the packaging with a pictogram represented by a pot on which there is a number and a letter M. The number and the letter M represent, in months, the recommended usage duration after opening.

Can the IN’OYA “face” products be used on the body and vice versa ?

The Correcting Serum can be used on localised hyperpigmentation spots on the face and on any other part of the body. However for the Unifying skin care products, it is better to follow the terms of use since the active ingredients correspond to a specific study for each of the different skin types. Whilst applying facial products to the body is not dangerous, applying body products to the face can cause reactions due to the fragile nature of the facial skin, causing it to have more specific requirements.

Should MEL’OYA Correcting Serum be applied all over the face ?

MEL’OYA® Correcting Serum can be applied all over the face. However, local application onto facial or body pigment spots is more than sufficient to treat pigment spots effectively up until they start to reduce or disappear.
