Let's talk about dark spots, uneven skin tone, and discoloration.
Below, I'll walk you through what's happening inside your skin when pigmentation forms, two products I love to interrupt that process, and my full personal PM routine 🙃

What Is Hyperpigmentation, Really?
Hyperpigmentation is just a fancy word for dark spots. Your skin made too much pigment in certain areas, and those areas ended up darker than the rest of your skin. That's it.
Your skin makes pigment naturally. It's called melanin, and it's part of your skin's built-in protection system. Think of it like your skin putting on a little suit of armor when it senses a threat. The problem is that system sometimes gets overzealous and makes more pigment than you need, in places you don't want it.
There are three main types:
Sun spots: dark spots caused by years of sun exposure. They usually show up on your face, hands, chest, and shoulders, anywhere that sees a lot of sun.
Post-inflammatory hyperpigmentation (PIH) is the dark mark left behind after your skin heals from something, like a pimple, a cut, or a rash. Your skin gets inflamed, and as it heals, it overproduces pigment in that spot. This is especially common in deeper skin tones.
Melasma is the tricky one. It's driven by hormones, often triggered by pregnancy, birth control, or just being someone whose skin is sensitive to hormonal shifts. It tends to show up as larger patches, often on the cheeks and forehead. It responds to the same ingredients as the other two, but it takes longer and requires more patience. If you have melasma, go into this with realistic expectations, not because it can't improve, but because it will improve more slowly.
All three start the same way, through a process in your skin that's worth understanding, because once you get it, shopping for products becomes so much easier.
How Pigment Is Made, and How We Stop It
Deep in your skin there are little pigment-making cells. Think of them as tiny factory workers whose whole job is to make color. They're called melanocytes...But just picture the factory workers.
Those workers don't run all day on their own. They need an instruction, and that instruction comes from something called tyrosinase, which is basically the factory manager. When the manager shows up and says "make pigment," the workers get busy. When the manager is blocked or not at work, nothing gets made.
So tyrosinase is the on switch. Most brightening ingredients work by turning that switch off.
But the manager doesn't show up randomly either. Something has to call the manager in. UV exposure calls the manager. Inflammation calls the manager. Hormonal changes call the manager.
So the full picture looks like this:
Something triggers the alarm (UV/hormones/inflammation)→ the manager (tyrosinase) gets called in → the factory workers make pigment → that pigment moves to the surface of your skin → you see a dark spot
To actually tackle hyperpigmentation, you want to interrupt that chain at as many points as possible:
Stop the alarm from going off in the first place
Block the manager so the workers don't get instructions
Slow down how fast the pigment gets handed off to surrounding skin cells
Speed up how quickly your skin sheds those pigmented cells off the surface
The best products do more than one of these at the same time.
The Ingredient Categories, Decoded
Here's a quick cheat sheet of the ingredient types you'll see below.
Tyrosinase inhibitors block the factory manager. No manager, no instruction, no pigment. Kojic acid, arbutin, and licorice root extract all do this. It's the most direct approach.
Enzyme-activated arbutin is a smarter version of regular arbutin. Regular arbutin knocks on the manager's door. Arbutase-activated arbutin kicks it down. Significantly more potent.
Melanin transfer inhibitors work after the pigment is made, but before it's handed off to surrounding skin cells (which is what makes it visible). Niacinamide and tranexamic acid work at this handoff step. Tranexamic acid also works even earlier, helping quiet the alarm signal before it reaches the factory.
Cell turnover accelerators, like retinol, mandelic acid, and glycolic acid, speed up how fast your skin sheds its surface cells. The pigment is already there; these ingredients help push it out faster.
Antioxidants, like vitamin C, glutathione, and astaxanthin, neutralize the UV damage that sets off the alarm in the first place. They're your prevention layer.
DNA repair enzymes work completely differently and aren't pigment inhibitors in the traditional sense. They repair UV-induced DNA damage so that old damage can't keep triggering new pigment production. They enhance the process.
Now let's get into the products.
Product 1: Remedy for Dark Spots
Dr. Muneeb Shah · ~$35
Amazon https://amzn.to/4xlczZC
Remedy https://go.shopmy.us/p-84174159 15% off orders $50+ and a free mini Vitamin C with orders $75+, now through Sept 7th
This is from the same dermatologist brand as the Remedy Copper Peptide Serum I've reviewed before, and the formulation philosophy is identical: stack multiple well-researched ingredients at meaningful concentrations, and keep the price accessible.
Here's what this serum is doing and why it matters:
5% Niacinamide works at the handoff step, blocking pigment from transferring to surrounding skin cells. Less transfer, less visible spot, even if some pigment was produced.
3% Tranexamic Acid is one of my favorite brightening ingredients. It works upstream, quieting the alarm signal before it even reaches the factory. Especially effective for PIH and melasma.
1% Kojic Acid (as Kojic Dipalmitate) blocks the factory manager directly. The dipalmitate form is gentler and more stable than regular kojic acid.
Mandelic Acid speeds up cell turnover so pigmented cells shed faster. It has a larger molecule than most acids, so it absorbs more slowly and is better tolerated by sensitive skin.
0.1% Encapsulated Retinol also accelerates cell turnover, working alongside the mandelic acid. The encapsulated form releases slowly, which reduces irritation.
Glutathione is an antioxidant with a really interesting extra ability: it actually influences what type of pigment gets made, shifting production toward a lighter form of melanin. It's not just preventing damage, it's changing the output.
Licorice Root Extract is another factory manager blocker, working alongside kojic acid to shut down the switch from two directions.
Tetrahexyldecyl Ascorbate is a stable form of vitamin C. Antioxidant protection and brightening in one, without the instability issues of pure vitamin C.
Acetyl Glucosamine helps niacinamide work better on dark spots specifically. They're a team.
Silymarin, from milk thistle, is anti-inflammatory and antioxidant, helping quiet the inflammation that triggers the alarm in the first place.
This formula is interrupting the pigmentation chain at almost every single step, which is exactly what I want to see. Use it at night. The retinol and acids make it sun-sensitizing, so it lives in your PM routine.
Product 2: Coleman Compound
Coleman Cosmetic · Cream + Pads
It comes in two versions, so here's how to pick yours (although it is a preference thing for sure, I prefer the one that technically shouldn't be for me...so play around with the formulas. Hopefully these "guidlines" will help if you are unsure):
The Cream https://go.shopmy.us/p-84174274 is for normal to dry skin, or anyone in a drier or cooler climate. Richer texture, more moisturizing, more comfortable for skin that needs that extra layer.
The Brightening Pads https://go.shopmy.us/p-84174309 are for normal to oily skin, or warmer and more humid climates. Same core approach in a lighter liquid format that won't feel heavy. This is the one I use. I love how easily it layers into my PM routine without adding any weight. Easily the best OTC pigment inhibitor I've used to date.
Both versions are used at night, before your retinoid. The brand recommends establishing the Coleman Compound routine for about 30 days before adding a retinoid if you're not already on one.
Here's what makes this formula stand out:
Arbutase-Activated Arbutin at 4% is the star. Regular arbutin is a key that fits in the lock. Arbutase-activated arbutin is that same key, but perfectly sharpened. It turns more effectively, blocks the factory manager more powerfully, and at 4% it's a meaningful concentration. This is an AMAZING ingredient. Dare I say revolutionary!
In the Pads, you also get:
L-Ascorbic Acid, pure vitamin C. Both a powerful antioxidant and a factory manager blocker. Combined with the arbutin, you now have two ingredients hitting the same switch from different angles at once. The pad format is great for L-ascorbic acid because it stays stable right up until you use it.
Kojic Acid, a third block on that same switch. Three tyrosinase inhibitors in one product is a serious commitment to shutting down pigment production.
Salicylic Acid helps shed pigmented surface cells faster and calms inflammation, which quiets the alarm that triggers pigment in the first place.
Rumex Crispus Extract, another plant-derived brightener with tyrosinase-inhibiting activity. A fourth angle.
Green Tea offers antioxidant protection against the UV damage that starts the whole chain.
In the Cream, you get:
Tetrahexyldecyl Ascorbate, the more stable vitamin C form, suited for the cream texture.
Glycolic Acid, an AHA that speeds up cell turnover and helps push existing pigment to the surface and off.
Glycyrrhetinic Acid from Licorice, yet another factory manager blocker.
Bisabolol and Allantoin, soothing and barrier-supporting ingredients that keep your skin comfortable while the actives do the heavy lifting.
Both versions are working the same strategy: block the factory manager from as many angles as possible, protect against the UV that triggers new pigment, and help your skin shed existing pigment faster.
My PM Routine
Cleanse Fresh Cleansing Jelly Balm is my newest joy 🙃
Pigment Inhibitor I am using the Coleman Compound Pads right now
DNA repair Enzymes (a step I will never, ever skip) https://photozyme.com/pages/penn-smith?ref=PENNYSMITH
35% off site-wide for Labor Day weekend
Copper Peptides I am using Remedy copper peptides
Tretinoin + Prequel Half and Half
Sometimes a moisturizer I love Drmtlgy Soothe and Recovery and I am also LOVING Sweet Chemistry Lipid Reinforcing Cream (Both are having Labor Day Sales as well, site-wide)
The Beginner Version (choosing from above if wanted)
Cleanse
Pigment Inhibitor
Retinoid of choice
Moisturizer if wanted/needed
The one rule that applies to both versions, beginner or advanced: SPF every single morning. Without it, you're fighting a losing battle. Your nighttime routine treats the pigment. Your SPF stops it from coming back. You need both, and neither one works as well without the other.
(I use vitamin C in the AM as a pigment inhibitor and antioxidant too btw).
The Takeaway
That's hyperpigmentation: the process, the ingredients, and two products I recommend to do the job correctly.
Remedy for Dark Spots if you want a comprehensive multi-active serum at an accessible price point from a dermatologist brand.
Coleman Compound, cream or pads depending on your skin type and climate, if you want the arbutase-activated arbutin approach with a more targeted philosophy. Also a dermatologist brand. This has changed my skin for the better. You can use this on hands and decollete also! The brand does have a beautiful body serum with arbutase and retinol as well.
And if you want to build toward the full stack, pigment inhibitor, DNA repair enzymes, copper peptides, retinoid, I hope seeing my routine laid out gives you a roadmap for how to get there gradually.
