I like alpha h Liquid Gold a lot having only started to use it a few weeks ago but I have concerns over skin damage caused by it stripping back the skin layers and then having exposure to sunlight even with an spf. Think I am on going to use it once a week in summer and then every second night in winter. I remember some people using a prescribed skin product as a moisturiser and then they had problems with a thinned skin. It too gave a lovely soft skin
glycolics take of the dead layers on the surface of the skin evenly. this is what gives the skin a glass like apperance and feel. it does not go deep down to the deeper layers
