The Good Molecules is yet another wonderful skincare brand with quality and decent skincare products at a pocket friendly price suitable to everyone’s budget (just like The Ordinary & The Inkey List), this brand is from Korea. According to them “The world has enough products that don’t work and cost too much, we started Good Molecules to change this.”

So, after using The Good Molecules niacinamide serum for 2 weeks, here’s my honest review about it. But before we go into that, its really a good idea to have a glimpse of what niacinamide really is, just in case if you’re new to this versatile ingredient.

What Is Niacinamide?.

Niacinamide is a type of vitamin B3 and a water-soluble vitamin that helps control excessive oil production, minimize large pores, Improve skin barrier function and improve overall skin tone which is very beneficial for all skin type but mostly for individuals with oily skin. Individuals with oily skin are very much vulnerable to acne breakouts due to excessive oil (sebum) production which can lead to clogged pores, so to regulate oil production you have to incorporate niacinamide into your skincare routine.

Good Molecules niacinamide serum is formulated with 10% pure niacinamide in combination with “glycerin” which is a great humectant that draws moisture into the skin from the atmosphere (just like hyaluronic acid), this product also contains “silicone” (dimethicone) to help avoid moisture-loss therefore helps retains water in the skin.

I know some will freak out upon hearing it contains silicone (which has been rumoured to clog skin pores) which is absolutely false.

Silicone (Dimethicone) not only acts as an occlusive which prevents moisture-loss from the skin, but it also helps protects the skin against environmental aggressors. Being an occlusive, silicone is non-comedogenic (won’t clog pores). According to Dr Lorenzo Branca., board-certified dermatologist in University Hospital Basel, Switzerland, “silicones can be imagined like a net. They form a “breathable” semi-occlusive layer and do not clog pores,”.

Silicones have a particular molecular structure with big gaps between each molecules. Skin can still sweat, and active ingredients can also reach the skin through these gaps. Silicones has no pore-clogging attributes — so, you absolutely have nothing to be concerned about.

My Review On Good Molecules Niacinamide Serum.

Good Molecules niacinamide serum review

This 10% niacinamide serum has proved to be a beast of its game. Just like the promised potentials of niacinamide, this serum delivers all.

My Pores.

I saw a huge improvement on my pores which now looks less visible, with my face looking sooo smooth and firm. Honestly I can’t stop touching and admiring my face.

My Complexion.

I saw great improvement on my complexion after using this serum for the first 5 days, I was like, “come on!! This is too good to be true, give it more shot“, I kept using it, and after 14 days, guys I can honestly say this liquid gold refined and transformed my complexion for good.

The little acne scars on my nose and both cheeks looked much lighter and almost completely faded, when I take a glance at my face through the mirror I see a dazzling glow with an obvious brightness.

Excessive Oil.

Being an individual with oily skin type, my face always feels greasy especially during the day, which was my main intention of using niacinamide serum in the first place (which has in turn given me more than what I asked for), my oily skin has been under control ever since niacinamide serum came into my skincare routine, all thanks to all previously used niacinamide serum, (including Good Molecules).

My face goes less greasy (unlike before), I put niacinamide serum on my face every day before I go about my daily activities and to my greatest happiness, I no longer suffer from excessive oiliness.

Good Molecules niacinamide serum feels absolutely hydrating when applied on the skin (you’re going to love the effect) and absorbs quickly. I have used it in combination with other skincare products and it doesn’t cause pilling (just like people complains The Ordinary niacinamide serum does). I use the Good Molecules niacinamide serum in combination with other serums and everything goes absolutely well without pilling.

What’s The Difference Between Good Molecules, The Ordinary & The Inkey List Niacinamide Serum?.

When it comes to the comparison of Good Molecules, The Ordinary & The Inkey List niacinamide serum I will say the three brands are wonderful and contains pure niacinamide serum at 10% concentration respectively. But as someone who has used the three niacinamide brands, I can boldly and precisely give my verdict on these 3 popular niacinamide brands based on their supporting ingredients and suitability to skin types.

For People With Oily (Acne-prone) Or Combination Skin.

If you have an oily (acne-prone) or combination skin, then you can give The Ordinary niacinamide serum a shot, reason being that, it pairs niacinamide with zinc which further helps minimize and regulates excessive oil production, refine the pores, reduces redness and irritation which in turn helps in treating skin with acne. So if you’re someone who suffers from constant acne breakouts due to clogged pores (as a result of excessive oil production) then The Ordinary niacinamide serum will prove useful due to the inclusion of zinc.

For People With Dry To Very Dry Skin.

If you have a dry to very dry skin, then you can go for The Inkey List niacinamide serum because it combines 10% niacinamide with other super-hydrating ingredients such as 1% hyaluronic acidsqualane and soyabean oil which helps keeps the skin intensively moisturized, hydrated, supple and soft, while niacinamide does its job. People with dry skin may not find The Ordinary niacinamide serum suitable, as it contains zinc which can be slightly drying to the skin, unless you’re going to mix it with your moisturizer prior to application in order to dilute the effect, but aside that, The Inkey List niacinamide is your best bet.

The inclusion of soyabean oil also makes The Inkey List niacinamide version a good choice if you’re looking to brighten your hyperpigmentation, due to the fact that soyabean oil has skin brightening potentials to tackle and fade pigmentations.

For People With Normal Or Sensitive Skin.

If you have normal or sensitive skin, then the Good Molecules niacinamide serum should be your best pick, reason being that the ingredients list is just simple and elegant, it contains 10% niacinamide as its main ingredient in support with glycerin and silicone which will have no adverse effect to your sensitive skin. Unlike that of The Ordinary’s version which contains zinc which can be overly drying for people with dry skin (which some people have bitterly complained about).

But regardless of your skin type, anyone can use Good Molecules niacinamide serum as it isn’t overly drying and not too hydrating too, it’s just on the moderate. And if you’re the minimalist kind of person who doesn’t like exaggerated skincare ingredients in a niacinamide serum then Good Molecules niacinamide serum should be your pick.

What I Like About Good Molecules Niacinamide Serum.

  • Good packaging.
  • Pocket-friendly price
  • Thinner consistency.
  • Absorbs Quickly.
  • Regulated Excessive Oil.
  • Improved My Complexion.
  • Fragrance-Free.
    Minimized Large Visible Pores & Smoothen The Skin.

What I Dislike About Good Molecules Niacinamide Serum.

  • The dropper is much slim. Due to that, I found it slightly difficult to pick up enough liquid from the bottle. I simply transferred the liquid into a finished bottle of The Ordinary hyaluronic acid serum to enable easier extraction. So, I think there is room for improvement on the product dropper.

Possible Questions & Answers.

A: No, it doesn’t foam when rubbed in your palm of your hands.
