Everyone's skin reacts differently to a product, so there is a lot of trial and error to figure out what is best for each individual. I was lucky the first thing I tried, helped. Biafine is a prescription ointment that has been used in France for over 25 years (available over the counter in Europe), but just recently approved for use in the U.S. It is used for burns, skin grafting, radiation dermatitis, diabetic ulcers, etc.... I looked at the prescription booklet that came with the ointment and it says consult with your doctor if you are trying to become pregnant, pregnant, or breast feeding. It appears that few studies or no conclusive studies have been done for safety in pregnant or nursing women, so it is not recommended for those groups unless the benefit outweighs the risk. It looks like Retin-A has the same risk/benefit caution as Biafine. There is a possibility that it can pass through the breast milk to the baby, even though that risk may be small. If it was me, I wouldn't take the risk if pregnant or nursing unless there were a lot of studies with reliable data on safety.
I started using Biafine two weeks after my IPL. I am nearly four months out now and my skin LOVES Biafine. It does clog my pores somewhat, but it does a good job of calming and hydrating the skin. It is supposed to be helpful in all stages of the healing process, so I think it would be beneficial at any point in time. Supposedly, it is a beauty secret of celebrities and they buy gobs of it while in France. Biafine provides deep dermal hydration; 41% of the water content reaches deep into the skin about an hour after application. It does sting and causes a bit of redness for a couple of minutes after application, but that sensation quickly goes away. I think others on here have also used Biafine. As with other products, it helped some people, but not others.
Recently, I started using oxygenetix during the day and I like that too. It contains a lot of aloe vera. It is available on dermstore.com and at many dermatolgists/plastic surgeon offices. It does seem to be helping with the clogged pores. Oxygenetix is often recommended for post-procedure, but from what I gathered reading blogs, many women continued to use it long term. It is also used for rosacea.
A lot of people on here have had good results from PsoriaGold. I just didn't try it because Biafine was immediately available to me and I was happy with the results. Who knows, if I started out with PsoriaGold, I may have been just as happy with it as well. Since I am past the inflammation stage, I need products that will help the texture and hydration of my skin. I believe PsoriaGold can be helpful for the inflammation, but I am not sure about the texture.
