Glycolic Acid And Tretinoin Combination. If you have been using tret for 7 years and have no issues of course try and use them in. In fact Masterson herself rotates between them mixing glycolic acid with marula oil one night and coupling a retinol with a mega-dose of hydration the next. Each group was primed with 4 hydroquinone and 005 tretinoin cream for 4 weeks before treatment. Since the skin is naturally acidic retinol can function well in the skin at a lesser pH level without any risk of undermining its effectiveness.
Now that its winter my derm recommended I switch to glycolic acid. It really depends on your skin and how long you have been using tretinoin and acids. The combination renders the effects of both useless as benzoyl peroxide will oxidize vitamin C. Significantly more patients in the azelaicglycolic acid group than the tretinoin group reported that they felt attractive. With the mouth opened maximally the interdental D and interlabial L distances were measured using a digital caliper. The combination of azelaic acid and glycolic acid is a useful alternative to tretinoin being at least as efficacious as the latter while offering a superior tolerability and patient approval profile.
But its not a hard and fast rule there is some evidence that tretinoin is more effective when used with glycolic acid and vitamin C.
What are the benefits of the combination of tretinoin and glycolic acid for your skin. Since the skin is naturally acidic retinol can function well in the skin at a lesser pH level without any risk of undermining its effectiveness. A common misconception is that glycolic acid and retinol cant be combined together due to their differing pH levels. However this is a myth and both can be very effective at the skins natural pH level. So yes you can use glycolic acid and retinol together you just need to listen to your skin. If the neutral pH was needed the combined retinol.
