There are no known long term side effects to Environ treatments. However, it is possible to have a reaction known as ‘a retinoid reaction’. This can happen when the skin has been depleted of its normal levels of Vitamin A for a period and its metabolic process has “wound down”, or the dosage of vitamin A is slightly too much for your skin at this particular time. You may experience slight dryness, flaking and in the worst-cases small reddish pimples that may itch. These reactions are perfectly normal and can be controlled, so it’s best to seek advice from your Environ specialist if you are at all concerned. Remember, not everybody will experience these problems; however, you should be aware it is possible and can be controlled with expert advice. More commonly, it has been known for a few breakouts to occur following an Environ treatment/use of environ products. Once again this is due to the skin acclimatising to the active ingredient Vitamin A and will usually settle within a few weeks.
