Get to know our ingredients


Wakame algae extract preserves and stimulates the formation of the extracellular matrix (ECM) that preserves the firmness and elasticity of the skin and works against wrinkles. Wakame extract is a key ingredient in the Serum, it stimulates hyaluronic acid synthesis and improves the natural skin barrier leaving skin nourished and reenergized.

Cotton thistle extract

Cotton thistle extract stimulates the regeneration of the skin and strengthens the skin barrier. At the same time, the extract counteracts moisture loss and improves the skin's moisture level. In this way, the extract preserves the skin's flexibility and softness, especially with dry or dehydrated skin.

Panthenol, Aloe Vera

The B-vitamin pre-stage panthenol (provitamin B5) nourishes the skin, has a moisturizing effect, reduces skin irritations and supports the skin's natural regeneration process. Combined with aloe vera, it soothes and strengthens the skin especially after exfoliation.

I got the serum with my kit and have to say it’s may favourite product yet! I started it ages ago and it really lasts. The packaging is great and makes it easy to use just the right amount. I have sensitive and dry skin so I have a hard time finding the right products. I’m really happy with this!

The serum is pure gold. Such a luxurious product - the price is really justified!I have tried all the expensive serums from Net-a-Porter and none of them were as good. The serum is not oily, but not too watery either. It is super highly concentrated and you can feel how the skin absorbs it. It leaves a refreshing feeling on the skin. In the morning I use a day care for more moisture. In the evening the serum is enough. Thank you Dr. Simon!

I have combination skin and this serum is just perfect. My face feels fresh and looks more even after every application, even one mark that has been there for months is now disappearing! I’ll def keep using this product.

Eine Freundin hat mir von den MDO Produkten erzählt, sie hat sich erst kürzlich das KIT gekauft und war bisher sehr zufrieden. Mir ist es leider etwas teuer, weswegen ich erst einmal das Serum ausprobieren wollte. Es fühlt sich bisher toll auf der Haut und und ich benutze es sehr gerne! Denke, ich werde bald auch einmal den Cleanser testen :)

Das Serum hinterlässt ein tolles Gefühl auf meiner Haut: Seidig, weich und glatt. Trage es unter mein Make-Up auf.

Are the products suitable for all skin types?

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

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.

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.

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.
