Are cell growth factors like the TNS essential in a good skin care regimen?
I hear you on this – state of the art products can be very expensive. So two things – no the TNS, in my opinion, is not essential. I think the essentials are a high zinc suncreen, an high quality antioxidant and a retinoid (like tretinoin, Retin A, Renova or a good retinol). The sunscreen is key and should be at least 5% zinc and somewhere between 5-18% depending on how much you are outdoors and the climate in which you live.
One approach would be to stop the TNS for two months and see how your skin behaves! Also, on husbands, I often observe that they will spend money on golf, books, cars, coffee, drinks with friends/coworkers etc., but not always consider their wives to be equal that way! Just an observation. 🙂
