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

Skin Conditioning, Solvent
Loved

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!

Smoothing

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Glycerin is already naturally found in your skin. It helps moisturize and protect your skin.

A study from 2016 found glycerin to be more effective as a humectant than AHAs and hyaluronic acid.

As a humectant, it helps the skin stay hydrated by pulling moisture to your skin. The low molecular weight of glycerin allows it to pull moisture into the deeper layers of your skin.

Hydrated skin improves your skin barrier; Your skin barrier helps protect against irritants and bacteria.

Glycerin has also been found to have antimicrobial and antiviral properties. Due to these properties, glycerin is often used in wound and burn treatments.

In cosmetics, glycerin is usually derived from plants such as soybean or palm. However, it can also be sourced from animals, such as tallow or animal fat.

This ingredient is organic, colorless, odorless, and non-toxic.

Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.

Pentylene glycol is typically used within a product to thicken it. It also adds a smooth, soft, and moisturizing feel to the product. It is naturally found in plants such as sugar beets.

The hydrophilic trait of Pentylene Glycol makes it a humectant. As a humectant, Pentylene Glycol helps draw moisture from the air to your skin. This can help keep your skin hydrated.

This property also makes Pentylene Glycol a great texture enhancer. It can help thicken or emulsify a product. Emulsifiers help stabilize a product. It does this by preventing certain ingredients from separating.

Pentylene Glycol also acts as a mild preservative and helps to keep a product microbe-free.

Some people may experience mild eye and skin irritation from Pentylene Glycol. We always recommend speaking with a professional about using this ingredient in your routine.

It's amazing. It's my HG serum when it comes to help my skin with hydration and moisture so far.

It has a dewy finish. I use around 6-8 dots for my face and neck, then I use a moisturizer on top. I have a gel moisturizer (anua soothing cream 70%) that isn't moisturizing enough, but with this, the very noticeable shine lasts max. 8 hours from night to morning (when I wake up), considering I don't usually wait 1 hour after doing my skincare before going to sleep. I wake up with softer skin as well. Even by afternoon though, when I skip using it in the AM, my skin is still slightly dewy (just not as noticeable), and softer than before.

So: it has helped me get a glass-skin shine when putting it on, and once the 8-hours pass and I don't put it on the AM, I still have a more natural shine which people with normal skin have, like some friends. I have a lot of dullness and my olive skin looks gray sometimes— especially on my cheeks, so this is really helpful.

I recommed it if you have dry or dehydrated skin. It is a bit sticky at first, so you can use it on slightly damp skin if it annoys you. Personally, I don't really mind, but I believe using it on damp skin helps with hydration as well (because the only thing that hydrates is water).

It can also be used in the morning, and the shine will last more time if you use a more occlusive product on top, which I recommend.

Only con is that it stings eyes a bit, but that's most products for me, because my skin is reactive and my eyes are very sensitive.

Overall, it's my favorite. I don't think I'll stop using it soon. Another plus is that it's a bottle of around 50ml, and you only need to use a bit, so it lasts a long time, around 1.5 months if you use it twice daily, and around 3 months if you use it once daily. I see most serums are 10ml-30ml, so this one is truly worth it.

Edit: I forgot to mention the smell. The smell fades away when you start putting it on after some seconds, and isn't strong to the point I would think it is fragance-free if it smelled more clinical, or like glue. I don't know how to describe the smell— perhaps slightly like flowers, but it's really light so not as noticeable. I have a sensitive nose and I don't like using perfumes usually, but this products works for me because of how light the smell is.

Good do-it-all serum for lazy people
I love this because I'm super lazy with my skincare.

I find this serum to be extremely moisturising without being too heavy and so, I use this as my last step in my night routine (without any other moisturiser)

On my laziest day's i'll just cleanse my face and slap this on.
