Medik8 is British cosmeceutical brand found by Elliot Isaacs in 2009. The idea of the brand has also roots in family member affected with rosacea situation (Mr. Isaacs’ sister) so the whole idea was to build the scientifically based brand but with accent on green chemistry and chirally correct form of ingredients used.

How to use it?

After cleansing in the morning, apply 4 drops directly onto face. Alternatively, place a drop on your finger and massage into skin. Leave to absorb before applying your regular Medik8 hydrator. Red Alert Serum can be used all over the face or on specific areas.

Follow with your daily moisturiser and sunscreen.

I’ve already used up 2 bottles of this serum in morning routines and although this is serum/oil type of product I like to use it immediately after toner. I leave it to absorb into skin (3-5 minutes) and then proceed with the rest of the routine.

It is not heavy, oily nor too moisturizing for the morning. Actually feels very light and with smoothing and slightly lifting effect immediately visible on skin.

This serum is thin viscous liquid (hence very hard to make photo of) of no colour and no scent.



Simmondsia Chinensis (Jojoba) Seed Oil, Cyclopentasiloxane, Cyclohexasiloxane, Caprylic/Capric Triglyceride, Tocopheryl Acetate, Teprenone, Salvia Offi cinalis (Sage) Extract

So here we are. This is the ingredients list with the star ingredient Teprenone drenched in jojoba oil, empowered with vitamin E and sage extract, and smoothed with some silicones and great emollient Caprylic/Capric Triglyceride derived from coconut oil and glycerine.

Teprenone is patented ingredient by Sederma (Patent No: WO2006120646 A1). Yes, these guys also patented Matrixyl. It is actually pharmaceutical drug (geranylgeranylacetone) used as treatment of gastric ulcers and Sederma’s experts found the way to actually use it topically with good results as anti-redness active ingredient also with strong anti-aging properties. It slows down signs of aging by expanding life span of skin cells. How? Teprenone delays shortening of telomeres (protective cap on the end of DNA strand that get shorter and shorter every time cell divides).

It also improves skin moisture and the appearance of rough skin, fine lines and enlarged pores. Phew! So imagine how rosacea skin can benefit from this one!

Sage extract has anti-inflammatory properties but can be slightly sensitizing for some people. Use with caution.

Rosacea safe?

YES, but if you are allergic/sensitive to sage, or don’t prefer silicones, no. To me personally, this is HG product, and my skin is highly reactive.

Who is it for?

Everyone with red skin, hypersensitive skin, irritated skin, aging skin.


Does it work?

Like I said, to me personally, this is HG product. I used up 2 bottles, and will keep repurchasing it. But at first I was like: what? Is this supposed to do anything? Meh! Then it just stood there for almost 6 months in my “meh products” vanity section. But, this is a not cheap product and I was rather keen on using it up just to get rid of it and justify those 50$ spent on it. Then I started to use it every morning and when I finished the first half of the bottle, things got dramatic. Suddenly, my skin reacted great to this serum. It was smooth, calm, with no visible redness, all in all healthy-looking. And then I fell in love with this product. From the “meh section” to HG status. Now it’s a staple of my routine. I do however make pauses of about 3-4 weeks and then continue to use it just to avoid my skin getting used to it.

As a rosacea sufferer, I can conclude that Teprenone actually does good job on reducing erythema or even calm rosacea flare-ups. My skin looks better, it is healthier, it is stronger and more resilient to the things that used to be absolute triggers of my rosacea flare-ups.

This serum was actually one of game changers that lead me to where I am now – no longer drunk-look-alike, teenager with zits in my forties.
