SerumScoop: Tips, tricks and news
TNS Essential Serum® by SkinMedica® Allergan® has a very fancy pump bottle that contains two different chambers. You dispense both sides at the same time, and are instructed to mix the two together on the back of your hand.
One side of the pump has a pH of 5, and the other just less than that, at about 4.5.
We're inclined to think that the dual pump of TNS Essential Serum is essentially a marketing gimmick. What's the point of keeping two halves of the product separate, only to mix them together?
Growth factors and certain peptides are rendered less effective at a pH of less than 5. Presumably that is why the TNS product is packaged that way, although we of course can't be for sure (the manufacturer doesn't mention why). When you mix the two parts of the product together, of course you also blend the two pH levels, and would presumably also negatively affect any sensitive growth factors once mixed.
That's why our Ultimate Serum has a pH of about 5.8. It's a low enough pH to create a good acid balance on your skin, but not too low to adversely affect the sensitive growth factors and peptides in contains. All in one nice, but non-fussy, bottle. That's one reason why we can offer our Ultimate Serum at such a fair price. Ounce-for-ounce, it's about 1/4th the price of Skinmedica's TNS Essential Serum even though it contains the top 23 ingredients of that very effective, yet very pricey, product.

Ultimate Serum is the first direct competitor to award-winning TNS Essential Serum® (NEWBEAUTY™ Beauty Choice Award Winner and InStyle™ Beauty Award Winner) by SkinMedica® which is now owned by Allergan, Inc. The patent on the TNS product relates to the medium called NouriCel-MD®, a "proprietary blend" of growth factors. We at Reviv Serums outflank this patent by simply providing our growth factors in a different conditioned media. In addition to the growth factors, we also include 25 of the top primary ingredients in TNS Essential Serum, and leapfrog by adding two of cosmetic chemistry's latest ingredients: stem cells and hexapeptides.
It’s the ultimate rejuvenator in a single serum. Navigate to its product page here.
