Just wondering if there is a difference between these two? I have many acne scars and have been dermarolling for a few months. I do get the occasional acne but not as much as I used to. Therefore, was wondering if it is a good idea to use any of the above gels on the days that im not dermarolling - as suggested by you in another thread. But which one?
Please advise.
Thanks & Regards.
Sid,
First things first, what is your skin type? One is a prescription and the other is not. If you want to treat acne, your first line of defense and "gold-standard" is benzoyl peroxide hands down. Go easy and be patient with 2.5% benzoyl peroxide along with 0.5-2% salicylic acid exfoliant products. You should check out the
acne thread I made.
When you say "Retino A" do you actually mean "retinol" or "retinyl alcohol" or "vitamin A alcohol"? There are several derivatives of Vitamin A and each one has its own unique chemistry and research background. For example, Retin-A or Renova
(tretinoin aka all-trans-retinoic) is the active chemical and extensively researched and is considered the "gold-standard" for treating photoaged skin, even though it was first geared toward treating acne vulgaris (still is). Our skin has receptor sites that binds with retinoic acid to promote healthy skin ce Tretinoin does have its known drawback, that is it can be irritating depending on strength of the prescription (0.025%-0.1%), due to its acidic property. Not everybody can tolerate this chemical, so they pick a milder form of vitamin A, still effective yet less side effects. Sarah Vaughter sells an affordable international version called,
A-Ret, that has a gel consistency and 0.05% all-trans-retinoic acid. There may be alcohol in the formalation so make sure you can tolerate topical alcohol. If you cannot tolerate her version, you might be better off with a more emollient base tretinoin cream (like Renova). Emollient can make your skin looks shiny if you already have oily skin. According to the Cosmetics Cop, Paula Begouns elaborate on the consistency of prescription Vitamin A products:
"
•Retin-A has a lightweight cream texture and is most often prescribed for acne.
•Retin-A Micro has a gel texture with a matte finish that's best for oily, acne-prone skin
•Renova has an emollient texture and is prescribed for wrinkles/sun damage.
•Tri-Luma contains tretinoin along with prescription-strength hydroquinone and is prescribed for discolorations and melasma
•Atralin, Avita, Altinac, Refissa, and Tretin-X are other prescription-only products with tretinoin. Retinol is very popular and is available in many local drugstores and department stores. Its known cosmetic range of potency is around 0.1-1.0%. It can also cause irritation depending on potency. An affordable option for normal to dry skin is Neutrogena Healthy Skin Anti-Wrinkle Cream, Night. For oily skin, you may like Paula's Choice Skin Balancing Super Antioxidant Mattifying Concentrate Serum. Want a higher-end retinol product? Try SkinMedica Age Defense Retinol Complex for normal to dry skin types. For all skin types, you may prefer SkinCeuticals Retinol 0.5 Refining Night Cream OR SkinCeuticals Retinol 1.0 Maximum Strength Refining Night Cream.
If you have sensitive skin (i.e., easily inflammed, stinged, etc), then you want to considered a nonacidic form of vitamin A like retinyl acetate or retinyl palmitate. Retinyl palmitate is less effective because it needs to be broken down several time. According to smartskincare.com, Dr. Torodov states, "
Not all forms of vitamin A are created equal. Some are more easily converted to retinoic acid than others. A typical conversion pathway looks like this: Retinyl palmitate <=> Retinol <=> Retinaldehyde => Retinoic acid" (
LINK). I am not aware of how many times retinyl acetate needs to be broken down. Sarah sells an affordable ointment,
Infadolan, with 0.1% retinyl acetate that is best applied after derma rolling to provide a protective barrier along with the cell communicating benefits of Vitamin A & D. This product may not be right for everyday use for your skin if you happen to be very oily and acne-prone, so I suggest you only use it a day or two after rolling for caution sake.
