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 apply this serum daily under my day cream. It is very abundant and nurturing. It leaves no oily film on the skin, which was important to me.

The serum is wonderful. It just leaves a light film on the skin which disappears after a few minutes. Because of my skin's tendency to impurities, I have a lot of pigment spots, so I haven't noticed a weakening effect yet. I also use it only irregularly, maybe I need to use it more often. The skin feels very well taken care of.

A great serum that can be wonderfully applied all over the face and around the eyes, leaving the skin feeling soft, smooth and nourished. It is absorbed very well, does not shine and prepares optimally for the daily routine.

I really like the serum. It’s a great product that makes me feel like I’m giving my skin what it needs in terms of nourishment and hydration on a daily basis. I read about all the ingredients and trust that Dr. Simon only uses the best ingredients. Recommend if you’re looking for a great every day serum to make your skin feel healthy and look great.

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.
