Blog with Dr. Irwin

I recently ordered Retin A and was given desonite cream. Are they similar drugs? I use it for wrinkles.

Dear Dr. I, I bought your recommended IS Clinical Eye Complex,which I like very much and was contemplating reordering. Question...you never seem to mention packaging (like Paula Begoun) and mine has been opened tons of times. Am I loosing potency with this type of jar after repeated openings? cheryl in CA

What do you think of Obagi cosmetics?

What do you think of Obagi cosmetics?

Can I use tretinoin cream with hydroxy acids or ascorbic acid serum if I can tolerate it? I heard that these ingredients inactivate each other when used together at the same time.

I know there have been concerns (at least in theory) about abnormal cell growth from topically applied human growth factors. You recommend TNS Recovery Complex and I would love to be reassured that there is little danger from using it since I'd love to try it.

Hi Dr. I!I have a question regarding skin care products. I am such a fan that I have aquired the products you use and recommend to see what works for me. I guess at this point I have become a little neurotic/obsessed with my skin as I see the changes that I know are inevitable. So, how much is too much??? This is what I am doing right now. Night time: Obagi Nu-derm (hydroquionone 4%) for the brown spots, TNS Recovery Complex, Eye cream, Revaleskin Night Cream, and a moisturizing lotion (dry skin).Day Time is much harder for me to figure out. Obagi Nu-derm (hydroquionone 4%) for the brown spots, TNS Recovery Complex, Eye cream,SkinMedica Vitamin C & E, Moisturizer (Dry skin), Zincclear Sunscreen and I am trying to figure out if I can add a firming/wrinkle filler for the slight wrinkles that are NEW ON my cheeks and then Makeup (foundation, blush, lipstick)!!!!I\'m almost 40 and my skin has become dry, a few brown spots and NEW (very noticeable to me) wrinkles under the eyes and cheeks. Do the products work as well piled on??? I was told I should use a \"treatment\" type product such as \"Perricone Md\" face firming activator and/or \"Substiane\" (La Roche-Posay). There is just so much. I know a lot of it is trial and error and I know everyone is different. I apoligize for this \"book\" I have written in trying to ask you for your advise and what is too much product and if am I going over board if I throw in an extra wrinkle filler or two in my daily regimen??? Thank you for your time and for this website.

I there a product that you can use for sagging skin around the jawline, withouth injections.

This time I will provide my city: I currently live in Washington DC and do go in the sun, but try to wear a hat, sunglasses and sunblock (for my face) - sorry, I do tan my body! I am in my mid/late 30s and was researching products that actually build collagen...I read this article (link below). This all sounds great about Azure and peptides originally being provided for burn victims -- the manufacturer of this product really make a good case when they claim these ingredients were used to generate cell growth in burn victims. THAT SAID, I wonder...are these claims true? Seems too good to be true that a product would actually INCREASE collagen growth? Thank you!
