You won’t regret using tret, it’s the best thing you can use for your skin to avoid lines, ageing and improve your skin, the difference in mine has been massive since using it. You can get it without seeing anybody just fill in a questionnaire online from Dermatica or Skin and Me. I prefer Dermatica because Skin and Me irritated me.
You use it only at night time and build up slowly in strength and frequency, so start using it maybe 3 nights a week then increase if you don’t have any irritation.
Keep your routine simple to begin with so at night cleanse, treat then moisturise, or you can use the sandwich method until your skin gets used to it, so cleanse, moisturise, treat then moisturise again.
For strength start off low on 0.25 or 0.5%, Dermatica or Skin and Me will look at your questionnaire and photos you send in and determine what’s best for you. If you do find it too strong to begin with, or find after a while you are not reacting to it and want to increase then you can email and they will decrease or increase it for you.
If you do decide to go for it and use Dermatica I have a code which gives it you for a massively reduced cost for the first month so feel free to use it. Just for total transparency though I also get a referral discount for a month if you use this.
