Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Solvent

Propanediol is an all-star ingredient. It softens, hydrates, and smooths the skin. 

It’s often used to:

Propanediol is not likely to cause sensitivity and considered safe to use. It is derived from corn or petroleum with a clear color and no scent.

Skin Conditioning, Solvent

Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Stay hydrated!

Humectant, Masking, Skin Conditioning

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.

Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.

Skin Conditioning, Solvent

1,2-Hexanediol is a synthetic liquid and another multi-functional powerhouse. 

It is a:

  • Humectant, drawing moisture into the skin
  • Emollient, helping to soften skin
  • Solvent, dispersing and stabilizing formulas
  • Preservative booster, enhancing the antimicrobial activity of other preservatives 
Humectant, Skin Conditioning

Soluble collagen comes from animals and fish. It has a large molecule size, meaning it doesn't get absorbed into skin.

Instead, it sits on top of skin as a humectant to improve skin hydration. It has incredible water-binding properties and creates a water barrier on skin that prevents evaporation.

This ingredient is incredibly gentle and often used to counter more irritating ingredients.

While our skin does have collagen, this ingredient is not used by the skin for anti-aging. Applying collagen topically has not been linked to helping with collagen loss in skin. All the benefits of soluble collagen are related to hydration.

Fun fact: The name "soluble collagen" refers to its ability to dissolve in water.

Emollient, Humectant, Skin Conditioning

Hydrolyzed collagen has a misleading name because it is actually a mixture of various proteins/peptides. This ingredient has skin hydrating properties.

Collagen is the most abundant type of structural protein found in your body. In your skin, it is responsible for keeping it firm and youthful.

Hydrolyzed Collagen is created by breaking up proteins into smaller peptide bonds. These peptides act as humectants and emollients.

Humectants are great at holding onto water, keeping skin hydrated. Emollients create a thin barrier on the skin to prevent moisture from escaping.

There is ongoing debate about whether hydrolyzed collagen works because it increases skin hydration. Skin hydration is also linked to elasticity and the appearance of wrinkles.

Collagen or peptide ingredients can be used in the morning or night. They will not increase sun sensitivity, but you should always wear sunscreen during the day.

According to a manufacturer, this ingredient is a great hair conditioner as well.

This ingredient can be extracted from different sources, including:

Vegan collagen is derived from yeast, bacteria, or plant sources. Vegan collagen would go by a different INCI name, such as hydrolyzed soy protein.

The results are varied.

A study from 2021 found hydrolyzed collagen increased elasticity and improved wrinkles in 1,125 participants between age 20 and 70. Another study found increased skin thickness in participants between the ages of 45 to 59.

However, It is difficult to prove that oral collagen will end up working on your skin. Many of the studies using hydrolyzed collagen also add several vitamins and nutrients into the test mixture as well.

Further studies are needed at this time.

It’s not a bad vitamin c - it doesn’t smell bad or sting my sensitive skin. It does leave a weird texture on my face though, like I’ve applied an oil or something. Odd.

I ended up receiving this product as a Christmas gift alongside Medicube's Age-R Booster Pro device. (I plan to create a review once I hit the 2 month mark!). I will say while the product does deliver the advertised glow, provides a great slip with the Booster Pro, and has a nice cooling feel upon application there are a few things I disliked about it. For one, I found this product to be extremely Show more
