Product Use

Are the products suitable for all skin types?

MDO products are suitable for all skin types. However, if you have extremely sensitive skin and/or are unsure please consult with your doctor or contact Simon Ourian M.D. here.

Is the treatment preferably for use in the evening or morning?

The MDO Skin Transforming Kit treatment can be used in the morning or in the evening. If you use the treatment in the AM, please make sure to apply a broad-spectrum sunscreen rated SPF 30 or greater during the day, as the The Exfoliant may increase your skin's sensitivity to the sun.

How often can I use the MDO Skin Transforming Kit?

Depending on your skin type, the MDO Skin Transforming Kit can be used as a daily routine or as a 28-day treatment. For sensitive skin we recommend four treatments per year.

Is The Exfoliant suitable for sensitive skin?

If used correctly – once a week over four weeks for a maximum of 10 min per treatment – The Exfoliant is suitable for sensitive skin. However, if you have extremely sensitive skin, it's best to test the Exfoliant first. Please refer to our application instructions available on the respective product page.

Can I use the kit during pregnancy? / Are the products pregnancy safe?

Dear Moms-to-be – please make sure to discuss your skincare products and routines with your trusted gynaecologist. In general, it is recommended that pregnant women avoid vitamin A, essential oils and caffeine, as well as metabolism stimulating treatments and also products that reduce the skin’s sensitivity to light. Accordingly, The Exfoliant is not suitable for use during pregnancy, as chemical peels in general can reduce the skin's sensitivity to light.

Do you recommend using a cream in the end after the routine or not?

If you have dry skin, we recommend applying a hydrating moisturizer after The Serum.
