Mandelic Acid is an alpha hydroxy acid but it has a number of chemical properties apart from acting as an exfoliating solution which does not trigger erythema. Its ability to help control rosacea has been shown but its actual mechanism of action in treating rosacea symptoms of reddening and thread veins is unknown but there is evidence that may point us in the right direction. It is ideal for those prone to reddening.
It is known to be antibacterial and antiviral and also helps to encourage vascular turnover and regeneration while suppressing reddening skin chemical reactions. Enerpeel MA 40% will reduce the thickness of the stratum corneum from 37 microns to 25 microns immediately after the peel and then it will reduce further over next 24 hours to 23 microns.
So Enerpeel MA is an exfoliating peel where the Mandelic Acid AHA molecule size means it is absorbed more slowly and hence does not trigger Erythema and therefore does not trigger excessive reddening or post inflammatory pigmentation, in fact it may act as a tyrosinase inhibitor and help control over active pigmentation. It can also be used as a pre peel similarly to Jessners.
