Skincare should change with the seasons. Especially your serums, given that they are the step in your routine where you really tune in with what your skin needs that day (read more on serums here).
The Good Molecules Discoloration Correcting Serum for example is one for the summer. Why? Because as the name would suggest it has the focus on fighting hyperpigmentation, something we tend to suffer more from when the sun is out and so are we.
Case in point? As a reminder of the care- and SPF-free days of my youth, I have a set of irregular formed dark spots on my forehead (as well as some postinflammatory hyperpigmentation on my cheeks, but these are from breakouts rather than sunbaths). In winter, they are barely noticeable, but despite SPF and sun avoidance, they reappear every single summer without fail.
Which is why in the summer months you can see me including every single thing in my routine that promises to fade them – like the Good Molecules Discoloration Correcting Serum.
What the Good Molecules Discoloration Correcting Serum claims
Improve the appearance of skin discoloration and uneven skin tone with Discoloration Correcting Serum from Good Molecules. Formulated with tranexamic acid and niacinamide, this lightweight serum improves the appearance of age spots, acne scars, hyperpigmentation, and sun damage.
Facts about the Good Molecules Discoloration Correcting Serum
Prize and size
One dropper bottle made from frosted glass contains 30 ml and retails for 12$ on the website here.
Texture and smell
A clear, slightly gel like liquid with no noticeable scent that sinks in quickly.
How to use the Good Molecules Discoloration Correcting Serum
While it could be used both morning and night, I reach for it mainly in the evenings and only if I don´t use my prescription retinoid.
You can technically pair Tranexamic Acid with retinol, but I try to keep my actives separate from my prescription (read here why).

Niacinamide, humectants and Tranexamic Acid. I will have a whole post on how Tranexamic Acid works here, but for now let me tell you that it is a promising ingredient that can, when used in conjunction with other actives, help reduce hyperpigmentation.
Does it live up to its claims?
Yes.
Both Niacinamide and Tranexamic Acid will help in reducing hyperpigmentation in the long run.
How does the Good Molecules Discoloration Correcting Serum compare to…
The Inkey List Tranexamic Acid Night Treatment
The biggest difference for sure is that The Inkey List tells us the concentration of Tranexamic Acid they are using (2%), while Good Molecules doesn´t share that information on the package.
Another noticeable difference is that The Inkey List uses a Vitamin C derivative to go with it, while Good Molecules pairs it with Niacinamide. Other than that both are similar in price and texture, and as it is always the case when talking about hyperpigmentation, results are too slow to achieve to be able to really compare the two in terms of efficacy.
Good Molecules Daily Brightening Serum
Another serum by Good Molecules that promises even and bright skin, but this one has the focus on Arbutin. Both Arbutin and Tranexamic have their place in fighting hyperpigmentation, so I think you are well advised to use both if you are suffering from stubborn sun spots.

Would I repurchase?
Maybe.
I like the serum, but think I might prefer the version from The Inkey List ever so slightly, simply because I have so many Niacinamide steps in my routine already.
Whom do I recommend the Good Molecules Discoloration Correcting Serum to?
People that suffer from hyperpigmentation. If your skin is very sensitive, go slowly, as Tranexamic Acid, while usually well tolerated, can irritate sensitive skins.
