Reviewing the 111Skin Y Theorem Day Cream

Anyone who has read my posts for any length of time knows that I love trying new skincare.  Because of this I often try samples to see how they perform.  I find this saves both on money and waste.  After all regardless of the price there is no point in purchasing something that you won’t use.  While samples can’t tell you the whole story, they can give you an idea of how the product will work.  They can let you know if you like the feel of it, or if you are going to have any reactions to it. 

Somewhere along the way I managed to test a sample size of the 111Skin Y Theorem Day Cream NacY2.  I’m guessing it was a subscription box, but I have no idea which one or when it arrived. I tend to put my samples in a plastic container and just reach in when I want to try something new or set up a travel bag. But one morning I did pull the sample from the container and tried it until it was gone. If memory serves it lasted a little over a week. During that week, I liked it enough that I put it on my ‘to test in a full sized version’ list. For the past six weeks or so I have actually been using the full sized version of this day cream. And I am now ready to give my thoughts on it. 

First let’s look at the official description.

The vitamin, antioxidant, and Hyaluronic Acid-infused formula plumps and revitalizes the complexion while keeping the skin feeling hydrated and nourished. This rich Day Cream works to infuse the skin with anti-ageing active ingredients whilst providing a protective barrier to shield the skin from harmful aggressors. Ideal for people who work in polluted or urban surroundings, the Y Theorem Day Cream NAC Y2 is formulated to reduce the effects of environmental aggressors.

NAC Y2: A fusion of three ingredients that all improve antioxidant levels, providing the optimum environment for collagen and elastin production and reducing the effects of environmental damage. HYALURONIC ACID: A humectant naturally occurring in our bodies that captures and retains moisture in the skin, improving hydration and causing a plumping effect. VITAMIN COMPLEX: A potent combination of Vitamin A, C, E, F and H to help repair damaged skin and protect against environmental pollution.

Ingredients: AQUA / WATER / EAU, ISOPROPYL MYRISTATE, PEG-40 HYDROGENATED CASTOR OIL, CAPRYLIC / CAPRIC TRIGLYCERIDE, PEG-100 STEARATE, GLYCERIN, BENZYL ALCOHOL, ORYZA SATIVA BRAN (RICE / RIZ) OIL, OLEA EUROPAEA (OLIVE) OIL, SODIUM HYALURONATE, CARBOMER, PEG-7 HYDROGENATED CASTOR OIL, SODIUM HYDROXIDE, POLYSORBATE 20, RETINYL PALMITATE, TOCOPHEROL, LINOLEIC ACID, STEARIC ACID, SODIUM ASCORBYL PHOSPHATE, AESCULUS HIPPOCASTANUM EXTRACT, ACETYL CYSTEINE, FRAGRANCE / PARFUM.

So let’s look at that a little deeper at a few of the top listed ingredients.  Water, I think we are all familiar with and know it needs to be in any skincare that seeks to plump the skin.  After all it is hydration that helps with the plumping and the water has to come from somewhere. It is much better coming from the cream than deeper in your skin. ISOPROPYL MYRISTATE is an emollient and it helps the skin retain moisture.

PEG-40 HYDROGENATED CASTOR OIL I actually find kind of interesting.  I’ll admit I went a little science crazy in the deep dive of this ingredient but don’t worry I’ll keep it short (and provide a link or two for those interested.  Put simply it is too large a molecule to be absorbed into the skin and so it stays on top and stops moisture from leaving.  I found that really interesting.  I’m used to sing ingredients that help lock moisture into the skin as they absorb but I never really thought about having something that doesn’t penetrate the skin preventing moisture from leaving. 

It makes sense and I am certain other moisturizers use it, I just never thought about it and I don’t think it has been a part of any other moisturizers I have broken down before.  So I found it a bit fascinating.  This is one of the best articles I found to most concisely explain it if you want more information.

CAPRYLIC / CAPRIC TRIGLYCERIDE is coconut oil mixed with a glycerin and it helps both to smooth skin and soften it. In fact most of the ingredients on this list are used to both smooth and soften skin as well as work as antioxidants.

To be honest I really like this moisturizer for a couple of different reasons.  The first is that it is a day cream.  I know this sounds a little strange, but walk with me on this one for a minute.  I know that the thought of having one cream that you can use for both day and night time use is a good plan. However I am noticing that my skin needs different things in the day time and night time.  During the day I need a moisturizer that absorbs well, doesn’t clog pores and doesn’t make me feel greasy when I work out.  So during the day I need something on the lighter end of the spectrum. 

At night, especially in the winter when we have the heater running and the air in the house becomes drier, I need a heavier cream to get me through the night. I am not opposed to putting a sleeping mask over my moisturizer, but I would really rather have a good night cream and just occasionally add a sleeping mask to my routine.

This 111Skin Y Theorem Day cream worked really well in that aspect.  It is too light for me to use during the night but was perfect for me to use during the day.  It absorbed well and I quite frankly had no real problems during my trial of the cream.  It has a light clean fragrance that fades into the background and becomes a ‘skincare’ scent rather than something you can identify by scent profile (ie. cucumber, rose and so on). So there were no scent issues.  The moisturizer absorbed well and fairly quickly.  I have been using it for the past six weeks and we have been having an unusually cold spring.

In the past week warmth has returned.  This past weekend I actually got some of my seedlings finally transferred out of the greenhouse and into the garden. As a reference point usually that is something I do the weekend after Easter where I live. As it is warming up, I find I am having more problems with the cream absorbing.  I have been having a little bit of a greasy feel to my skin which is not something that happened at all in cooler temperatures.  I have a week or two left of the 111Skin Y Theorem moisturizer left in the jar and I suspect as the temperatures increase I will find it a little more greasy.  This cream seems to be a very good moisturizer when the weather is cool, not so much when the weather turns warm. 

I could be wrong (lord knows I have been wrong many, many times before) but I suspect it has something to do with the PEG-40 Hydrogenated Castor oil. According to all of the information I found, it is designed to sit on top of the skin.  In cooler weather this isn’t an issue, as the temperatures rise you can feel something sitting on the skin and for me it feels a little greasy.  Don’t get me wrong, it is not a major grease bomb, but it is noticeable to me.  I’ve had to pat my t zone with powder mid afternoon just a little bit more now that the central heating is not running.

You will notice that there are no before and after pictures with my skin and this cream. Part of that is because I accidentally deleted the photos in my grand spring purge. (I was so excited to make space on my hard drive that I simply didn’t think about what I needed to keep.) The other reason is that while this moisturizer did moisturize, any real work done on reducing fine lines I am pretty sure was done by other products. The hyaluronic acid in this moisturizer may have contributed, but serums and eye creams did the heavy lifting. This is a moisturizer and an environmental defense shield, it is not amazing at dealing with fine lines.

Over all, I do like this Day cream and I am very glad that I did try it in the full size.  I think that if I were to purchase this 111Skin Y Theorem Day cream again, I would do so knowing that it would be a moisturizer I would use in the cooler months and that I would need to pair it with some heavy duty anti-aging serums. Everything else has its season, why shouldn’t moisturizer. So in conclusion, yes I would repurchase this moisturizer, but I would be strategic as to when in the year I used it and what products I used it with so as to use it to its best advantage.
