Tretinoin stability issue ? need help
To introduce me quickly, i’m not chemist but only a engineer
( not in chemistery field).
I’m interresting a lot about anti aging and biochemistery since
I’m doing myself some products for haircaire ( because i
have a male pattern baldness) and anti wrinkles cream face.
All these are only for personal/family use.
I’m reaching you today because i have some doubts about tretinoin
I will explain you why :
I use a « standard night cream » then i put in it
some Coenzyme Q 10 powder and 0,025% raw tretinoin. Tretinoin is a very good
anti wrinkles agent ( boost collagen, help to cell turnover), that’s why i put
it in my cream.
Problem is simple, tretinoin, when used at 0,025% do some
flakes/Peeling on the face , it’s a standard reaction of tretinoine because it
enhance cell turnover. If i use 0,025% tretinoine from my pharmacia, i get
flakes/peeling on my face…
If i use my cream, with the same % of tretinoin ( yes, my
maths are ok 😊 ) : No flakes, no peeling.
My question is to know why i get no peeling/flakes with my
custom cream :
> Tretinoin react with another component in this
cream cream which destruct my tretinoin ?
> Tretinoin is OK but some component in the cream
prevent the peeling/flakes ?
> Other ?
I really would like to know the truth about in order to be able
to get my tretinoin working in this custom cream face. Any ideas ? Any preservative to add ?
Here is the night cream i use, here is the component :
Aqua, Glycerin, Cetearyl Isononanoate, C12-15 Alkyl Benzoate, Octyldodecanol,
Potassium Cetyl Phosphate, Hydrogenated Palm Glycerides, Panthenol,
Butyrospermum Parkii Butter, Cetearyl Alcohol, Glyceryl Stearate, Vitis
Vinifera Seed Oil, Tocopheryl Acetate, Sodium Acrylates/C10-30 Alkyl Acrylate
Crosspolymer, Cyclomethicone, Dimethiconol, Trisodium EDTA, 1, 2-Hexanediol,
Phenoxyethanol, Methylparaben, Citronellol, Benzyl Alcohol, BHT, Parfum.
Thanks a lot
