>1). May you please advise as to which size dermaroller i should choose? To improve the skin texture of your face, start with a 0.5 mm dermaroller (twice a week on the same skin area.)
You could use the 1.5 mm roller on your face as well but rolling your abdomen to improve stretch marks and sagging skin is quite a large area and you need a sharp dermaroller for that. If you use it also on your face, it will get blunt sooner.
>2). a) Is Retin-A totally necessary to achieve noticeable positive results with >dermarolling? No, it is not necessary to achieve results. Some people cannot use Retin-A because it irritates their skin.
Tretinoin (Retin A) is useful in certain skin conditions such as acne prone skin, hyperpigmentation, stretch marks, sun-damaged skin and dull skin, provided it doesn’t dry out or irritate the skin.
>b) Can the Infadolan cream be used alone, instead of retin-a? These two products are not interchangeable. Infadolan is indented for dermarolling aftercare. It protects the dermarolled skin. In your case, you should use it after rolling your stretch marks with the 1.5 mm one liner dermaroller or your abdomen with the regular 1.5 mm roller.
You do not have to use it after rolling your face with short-needled rollers such as a 0.5 mm roller but keep the skin moisturized.
>3). a) Are Copper Peptides necessary to achieve the results im looking for with >dermarolling? Dermarolling works all by itself so nothing else is necessary to get results. Our products (mainly vitamins) are an additional help to enhance those results.
You should keep the skin well moisturized after dermarolling. That is important.
>4). Vitamin C - Would a MAP serum be suitable for use whilst dermarolling, or does
>it have to be the L-Ascorbic Acid version of vitamin C? Non-acidic forms of vit. C failed to increase ascorbic acid levels in the skin:
“Derivatives of ascorbic acid including magnesium ascorbyl phosphate, ascorbyl-6-palmitate, and dehydroascorbic acid did not increase skin levels of L-ascorbic acid.”
https://http://www.ncbi.nlm.nih.gov/pubmed/11207686 It doesn’t prove that it had no effect on collagen production since this was not studied but further studies are necessary to find out. So keep using the acidic form (ascorbic acid) as well since this form did increase the levels in the skin.
>c) How should you treat your skin prior to application of the VitC? Do not use alcohol, it dries out the skin too much.
I wash my face with a little bit of diluted shower gel, rinse it off with tap water, I pour vit. C serum on a cotton pad and apply it to my face. About half an hour later I sprinkle a cotton pad with tap water, add some almond oil and apply it to my face.
If you do not use very oily daily creams, you can apply vit. C without wiping the oils off your skin first.
