Great dry spot treatment!
Worked wonders on winter dry patches on my cheeks and sides of mouth. I’m a somewhat new Prequel product user. I follow the creator on YouTube and love her skincare videos. I have tried a few products so far and have been happy with the results. I just ordered the foot repair ointment for my husband as well. I think this brand is a great value for the money. I have not had any bad reactions so far and I have VERY sensitive skin. This ointment is lightweight and melts into my skin well and the next morning my dry spots were literally invisible. It’s fragrance free, I did not notice any scent at all, which is importance to me.

Prequel is always great
Very soothing and calming for skin. Tube lasted a long time. I have sensitive skin and often have reactions but did great with this.

This is a barrier cream?
I also have very oily skin, so normally I stay away from anything that says barrier or balm. I push skin a lot lol...with max strength tretinoin, glycolic acids, salicylic acids, vitamin C... so there are times when I just need max help from a richer product bc sometimes I take it too far. LRP Cicaplast has been a staple and has saved me many a times.
I bought this bc of the high percentage of ectoin, 5%, and it was so reasonably priced. When I squeezed the tube, I was really worried, it was thicker looking than the Cicaplast. However, when I spread it out, it was SO light and a tiny amount --barely a pea size, was enough to coat my face. It did not feel heavy. Even with my oily skin, I think I could wear this everyday.
As an experiment, I applied any excess on one side of my hand, as I'm right handed, I would apply it on my left hand. I've had this about a week, and right now after doing the dishes, and washing my hands multiple times without any hand cream on it, my right hand is definitely drier than my left hand. My left hand also looks less red and more calm.
This formula is 5 stars for both the effectiveness and the elegant formula. It may yet replace my LRP Cicaplast...we'll see!
