What percent of vitamin c serum is best

These guys are both going to be 10% vitamin c serum. Which as you know, that sweet spot for the concentration level vitamin c is between 10 and 20 percent. 10 being a great beginner friendly level that is just right enough to start off with. Because its higher than 8 percent for it to produce results and quick tip, avoid going over 20 percent vitamin c, which could lead to irritation and doesn't increase its benefits either. Which is why youll see most products use 10, 15, or 20.

What type of vitamin c serum is best

The form of vitamin c they are in also matter too, they are both pure vitamin c in the form of l-ascorbic acid, which is the form you want. The other forms like, magnesium ascorbyl phosphate or ascorbyl-6-palmitate wont do the work you need. L-ascorbic acid is a highly unstable molecule however. SO does requires a water-based environment, a low pH, and antioxidants to increase its ability to really get into the skin deeply. Because you need it to get in all the way. And These 2 products ensure all of that.

Why does vitamin c serum turn brown

Oh and one more thing, because they use l ascorbic acid: they need great packaging otherwise theyll oxidize and change color when exposed to sunlight. Which both of them have good packaging in mind. So its not an issue with either one.

Cerave Vitamin C Serum

The first being is that it uses ceramides. And as you know, most cerave products incorporate, ceramides 1, 3, and 6-II. And ceramides are essentially just lipids found naturally in the skin and are there to protect your skin barrier and retaining moisture. Especially ceramide 1: as It contains the essential fatty acid, linoleic acid which plays a "binding role" in the lipid layers of the extracellular matrix. Basically think of these ceramides as a waterproofing for the face. The second ingredient is the fact that it uses, tocopherol acetate, or vitamin e acetate instead of just free tocopherol. And the reason why you see this, is because Tocopheryl acetate can be more stable, since then it is converted to its biologically active form, vitamin E, within the skin when applied topically. So its one extra step to ensure the vitamin e gets to the skin intact. The third ingredient, is cholesterol. And you might be thinking, why is there cholesterol in this product? Well, cholesterol is actually found naturally in the outer layer of the skin. About 25% of the mesh thats between our skin cells consists of cholesterol. So when cerave uses it in addition to ceramides, they are targeting a deeper problem that may be causing pigmentation, which is the skin barrier. Which I applaud them for.

La roche posay vitamin c serum

Now, there are 3 ingredients in here, that stood out to me as well. The first is: While both of them use hyaluronic acid, the la roche posay, uses both hyaluronic acid and hydrolyzed hyaluronic acid, Hydrolyzed Hyaluronic Acid is a low molecular weight, chemically chopped up version which may absorb easier into the skin. Which may help keep your skin moisturized longer. The second ingredient is: that is also uses Salicylic acid as the 27th ingredient. So not a hefty amount, but enough to reap some of the anti inflammatory benefits, Which at the levels in this product, it can be great for exfoliating the skin both on the surface and in the pores. And the third ingredient is the Neurosensine dipeptide of tyrosine and arginine as the ingredient: Acetyl Dipeptide-1 Cetyl Ester. Which is what really makes la roche posay unique. The dipeptide, works by stimulating the skin nerve cells to release met-enkephalin, which long story short, its a signal for the skin to relax and relieve pain. And the reason why its used, is so that it can instantly decrease skin irritations coming from heat, chemical stinging or mechanical stress on the face. This combined with vitamin c theoretically can really create the environment on the skin to support vitamin c’s brightening and glowing effects. So there may be some synergy there.

How long does vitamin c serum take to work

Vitamin C serums take at least 12 weeks to take effect because it takes time for new cells to regenerate and for pigment to start clearing. So keep up with it for the 12 weeks before you decide on what to do next. You wont believe how many people grow impatient and give up too early. Dont let this be you.
