When is retinol as effective as Retin A? When it's formulated at a certain percentage...or?
Is it ever as effective?
Thanks, BFG |

BFG, I don't know if you have seen this but a study was done on SkinMedica Tri-retinol and tretinion .025 giving the same results.
Carlsbad, CA – May 29, 2012 – SkinMedica Inc., recently named the fastest growing professional skin care brand for the sixth consecutive year, announced that two randomized, double-blind, controlled studies have demonstrated that SkinMedica Tri-Retinol Complex ES™ (containing tri-retinol 1.1% cream), a non-prescription gradual release retinol cosmetic product, performed comparably to topical prescription tretinoin in improving the appearance of subjects with facial photodamage. These high-quality head-to-head studies, conducted by The Johns Hopkins University and Colorado Springs Dermatology Clinic, are unusual for a non-prescription cosmetic product. There are many non-prescription retinol products on the market that claim to improve the appearance of photoaged skin; however, studies like these are rare and demonstrate that SkinMedica continues to raise the bar as a leader in the professional skin care market.
Sewon Kang, MD, Noxell Professor and Chairman and Anna Chien, MD, Assistant Professor & Director of Clinical Research in the Department of Dermatology at Johns Hopkins University are leading experts on the use of retinoids in patients seeking to improve the appearance of photodamaged skin. Their data support results from the previous published study for both safety and efficacy. Clinical studies are needed by clinicians in assessing claims of anti-aging products on the market.
The results of a trial conducted at the Colorado Springs Dermatology Clinic were published in the January 2012 issue of the Journal of Drugs in Dermatology. In that study, 34 females with mild-to-moderate facial photodamage applied SkinMedica Tri-Retinol Complex ES or tretinoin 0.025% cream daily to the entire face for 12 weeks and were evaluated at baseline and after four, eight and 12 weeks.
Both products significantly improved the appearance of photodamage at four weeks, with benefits increasing progressively over the 12-week trial.
Subjects reported greater than 93% overall satisfaction at weeks eight and 12.
There were no statistically significant differences in effectiveness between the two products.
Data from a second study conducted at Johns Hopkins University were presented at the Society for Investigative Dermatology Annual Meeting in May 2012. In that study, 24 subjects with moderate-to-severe facial photodamage applied SkinMedica Tri-Retinol Complex ES or prescription tretinoin 0.025% cream for six months.
Both treatment groups improved over time with respect to efficacy parameters and there were no statistical differences in degree of improvement or tolerability between the two.
SkinMedica Tri-Retinol Complex ES contains three forms of vitamin A, retinol, retinyl acetate and retinyl palmitate for 1.10% total retinoids, making it the highest concentration of retinoids available without a prescription. A patented MICROSPONGE® delivery system allows for gradual release over time, which is designed to reduce irritation that may occur with some topical retinoids. |

Has anyone tried SkinMedica Tri-retinol? I've tried a lot of products with retinol and they never impressed me as much as tretinoin. |

RS, if I was able to use RA regularly, I would definitely go that route without a doubt...I really do think RA is the gold standard. But even 1x a week causes me to get very red and peely, so I have had to stick with the lower strength retinols.
But the fact that SkinMedica uses all 3 versions in one product is pretty interesting...I am going to have to read more about that. |

I thought that 2% retinol was the highest concentration. |

Hi All,
I use the skinmedica retinol in the autumn and winter, and it is very effective. I love it.
When I was able to get retin-a covered by insurance, I loved using it, but the stuff that alldaychemist sent me was NOT retin-a by any stretch of the imagination. I ended up throwing out like four tubes of it, and buying the skinmedica product. It works really well, and another added benefit is that it works subtly and doesn't cause too much inflammation at once to the skin.

Why do you say that the stuff from ADC is not Retin A? I've tried both Retin A from a pharmacy and from ADC and I don't see a difference.

What I received was not retin-a, pure and simple. it was a strange yellow gel with large grit. I ordered retin-a .5% I used an entire tube, in of a stronger concentration that I am normally used to, and it never once produced any of the telltale signs of retinoid action on the skin. no redness, no flakiness, no visible turnover of skin after daily use for two weeks, nothing. in fact it looked, smelled, and felt exactly like vaseline. not sure what the gritty bits were.
some people have ben lucky and have received the real thing, but if you pay attention to all the reviews around, some people also got the gritty vaseline stuff.

Avalange, do you use the regular tri-retinol or the ES version? |

rileygirl,
I use the ES version. About twice, maximum thrice a week in autumn and winter, when I'm not exposing my skin to the skin (although I'm religious about sunscreen, don't want to take any chances!)

I also believe that ADC has experienced quality controls with their medications...I have experienced it firsthand.
I wish we had other sources that were similar in price, etc?
