Title: Dermarolling, Zinc-based sunscreen and sun exposure

               If you roll with long needles such as 1.5 mm you should completely avoid

        exposing your skin to the sun for at least 2 days after the rolling (just like in the majority of laser treatments). You must wear a hat and use a high-factor sunscreen if you go outside.

        It's alright to put Zinc oxide sunblock on but not immediately after dermarolling. Applying it the day after is OK.

(However it is much better to use any sunscreen including a zinc oxide-based one right after dermarolling than going outside unprotected from the sun - you could end up with hyper pigmentation. To offset the drying effect of zinc, just apply some cream to keep the skin moisturized and put the Zinc-based sun block on top).


        Dermarolling triggers collagen production but rolling also temporarily compromises the protective skin barriers and the sun is very bad for your recovering skin at that vulnerable stage.

                        Zinc oxide dehydrates the skin. Zinc oxide is a mild astringent. An astringent is a substance that shrinks and constricts body tissues.

  Zinc oxide acts as a skin-drying agent and can act as a skin anti-inflammatory. Astringents cause mild coagulation of skin proteins and that causes the skin to dry up.

     Zinc's "drying" properties are very beneficial in treating diaper rash, oily skin with acne or any other skin condition where drying the skin is desirable. After dermarolling though, the "open" skin should be kept as moisturized as possible and that's why substances with astringent and dessicating (drying) properties are not suitable.


Additionally, Zinc has a mild anti-inflammatory effect and optimal collagen induction and elastin formation is achieved after the mild inflammation that rolling causes. that's the reason we roll: To cause a controlled inflammation.

Zinc oxide or titanium dioxide are excellent physical sun  blocks. It works by covering the epidermis and reflecting the UV rays.

                  Another reason why you should stay away from your skin the first days is the risk of bacterial contamination.  If your sunblock has been used for a while and it is not in the tube, its probably already contaminated by your hands etc. If your skin is intact it doesn't matter but you should be careful when the skin protective barrier is compromised and you should only use tubes - not jars - where the risk of contamination is very low. That's why we chose Infadolan, which  is a medical grade regenerative ointment indicated for first degree burns.

Nobody can guarantee results, also not of any in-office treatment.

        There are people that underwent several in-office dermarolling sessions for their acne scars and they got disappointing results and there are people who roll themselves at home and they got good results. It depends on so many factors that we can safely say that a well-informed home-roller can get better results than a mediocre clinic can. Clinics are under time pressure and are there in the first place to make money (= getting you to return as often and as long as possible).

    You can try to roll yourself and if you get no results, try in-office treatment. Either way, it is unrealistic to expect results too soon.

Hi again,

I've just been looking at your products, the ointments in particular and am even more confused than I was before as to how and when to use them in conjunction with each other or separately.

For example, if I were to use the Vit C mixture at night, in between rolling, would I then also use the ointment which can only be used at night, on top of it?

During the day if I used the Vit C mixture, would I then use the Infadolan over it and, a sunscreen on top of both of those applications?

Infadolan ointment doesn't have to be used at night. Regarding A-Ret gel and vit. C: It is better to use those at night because they are sun-sensitive compounds, esp. Retin A. They do not have to be applied daily. Applying A-Ret daily will dry out the skin too much.


I tried to give here some ideas on how to combine:


  You should use the sunscreen during the day and in the evening after you clean your skin, apply vit.C.


If you use Infadolan right after dermarolling or you apply it daily around your eyes or on the back of hands for example, apply a sunscreen first and then Infadolan. (If you forget to apply the sunscreen first then apply it on top of the Infadolan).
