[REVIEW] Dr. Dennis Gross Firming Peptide Milk

The Dry Skin ‘Does it All’

Sometimes you want a product that’s corrective, but not drying. Moisturizing, but still a beneficial treatment. Dr. Dennis Gross’ Firming Peptide Milk is all that and a bag of chips.

This formula first starts off with my favorite Natural Moisturizing Factor; Squalene. NMFs are ingredients that are naturally occurring that can mimic our skin’s own moisturizing factor. Squalene specifically is also skin identical ingredient, meaning we can find it naturally occuring in our skin! It makes up ~12% of our skin’s sebum. But is considered to be superior for moisturizing not only just generally dry and very dry skin, but also for oily/unbalanced/acne prone skin. Next key ingredient down on the list is Tetrapeptide-21. Peptides are great repairing agents. Tetra 21 specifically is a state of the art peptide that can improve skin texture and the depth and size of wrinkles. Some believe it is actually the most effective peptide for anti-aging. Collagen Amino Acids, are present to help repair and moisturize.

 

One interesting ingredient note is Hydroxypinacolone Retinoate AND Retinol are both present. Retinol, a dermal exfoliator that helps correct signs of damage and aging by speeding up our skin cell regeneration. Hydroxypinacolone Retinoate is what I owe all my dark spot correction and retexturization, it’s best described as ‘Retinol 2.0′. It’s a trans-ester retinoic acid that works similarly to Tretinoin. (generally referred to as prescription retinols. Retin-A, Curology formulates with it, etc) without any of the irritation that comes along with Tretinoin.

Besides squalene, sphingo and phoso lipids also help protect and moisturize. Saccharide Isomerate is another designer ingredient known by the name Pentavitin. It is a water binding agent to prevent water loss. This serum is unscented and leaves the skin feeling incredibly soft and just lightly moisturized.

Now if those ingredients weren’t enough to get you to Sephora ASAP to check it out… low on the list a fantastic penetration enhancer is found, Demethyl Isosorbide. For me, this ingredient is a sign of a great formulation. It’s generally found in prescription treatments to ensure well, absorption. But also to help prevent ingredients from crystallizing before absorbing.

Dr. Dennis Gross is a guilty pleasure. Their price point can be high (at times) ((like the peel pads, cmon)). Their packaging is pretty dull (BUT PACKAGED FOR EFFICACY!) But their formulations never cease to amaze me. 

 

[REVIEW] Dr. Dennis Gross C + Collagen serum

Vitamin C & Niacinamide: a Potential Love Story

There’s always a new fancy type of vitamin C that’ll gain buzz for a few months. Sunday Riley is currently touting THD or Tetrahexyldecyl Ascorbate in their C.E.O line, Korres has ‘Super C’ or Ascorbyl Tetraisopalmitate, some brands prefer the tried and true L-Ascorbic or pure form of vitamin C. But Dr. Dennis Gross has recently launched his newest vitamin C serum focused on brightening skin tone and supporting collagen production sporting 3-0-C, or Ethyl Ascorbic Acid.

Vitamin C is a great ingredient. Arguably one of the most anti-aging non invasive ingredients you can slather on. But being an active ingredient it does have a vitamin it doesn’t like to mingle with. Niacinamide! (or vitamin B3) All forms of vitamin C eventually metabolize into L-Ascorbic Acid, the raw form of vitamin C. Some take longer, but it’s generally deemed safe to use Niacinamide and other forms other than L-AA together. When Niacinamide and L-AA mix they can potentially form what is known as a ‘1:1 complex’ and render each other useless. No vitamin C, no Niacinamide. This is still a grey area for cosmetics and cosmetic formulators. Some believe you should have the two used at separate times (such as morning and night). When mixed they produce a substance called nicotonic acid which can cause skin flushing, and irritation. However it’s said it could be as, or more effective than Niacinamide on it’s own. This usually is not the case again, with forms of vitamin C other than L-AA. Some brands, like Dr. Dennis Gross are using them side by side. If you’re interested in all of the interactions with vitamin c and niacinamide I would recommend checking out this post by KindOfStephen it’s super informative, and he goes over the in’s and out’s of it and what nicotinic acid is.

3-0-C has a small list of benefits it touts over other forms of vitamin C. The biggest one is that it is both oil and water soluble, allowing for maximum absorption. It shows great improvement in hyperpigmentation/dark spots by inhibiting Tyrosinase activity therefore slowing down Melanin synthesis. It’s also a great antioxidant and is shown to be very stable in formulations. To read more aout 3-0-C this is a relatively easy to understand study on it check it out here.

One of my biggest complaints about vitamin C serums is the consistency. SO MANY are tacky, or leave a less than desirable feeling. While I unfortunately can’t tell you this could be an exception, it still feels a little like a sticky vitamin C serum. It isn’t nearly as tacky as say, OST 20, but not great. No weird smells, or gimmicks just a quick absorbing well formulated vitamin C.

To make sure you’re getting more than just your anti-aging/brightening effects with the Niacinamide and vitamin C team, you can also find Superoxide Dismutase (SOD) a lesser known Skin Identical ingredient (something found naturally occurring in our skin) that inhibits oxidation. Hexylresorcinol, a UV protectant and potentially a skin brightening ingredient. Lastly to note, Collagen amino acids, a favorite of mine to provide moisture and building blocks for collagen production.
