Apply 4–6 drops of Serum PIGM 400 to clean skin after Lotion P50 and before moisturizer, morning and night. Massage into the face or spot-treat pigmentation.
Serum PIGM 400 is one of Biologique Recherche’s most powerful tools for fighting hyperpigmentation and uneven skin tone. It’s not just about lightening spots, it’s about protecting your skin from future discoloration.
If you’re struggling with sun damage, dullness, or persistent pigmentation, this article will walk you through exactly how to use Serum PIGM 400 for real results.
The Real Deal On Serum PIGM 400: Who Needs It And Why It Works
I’ve tried just about every “brightening serum” on the market, and most of them? Hype.
What makes Biologique Recherche’s Serum PIGM 400 stand out is that it actually delivers. It’s not about lightening your skin into something it’s not. It’s about refining your tone, softening pigmentation, and restoring radiance in a way that feels intelligent and elegant.
PIGM 400 is designed to:
Fade stubborn dark spots and sun damage
Prevent future pigmentation from forming
Brighten and unify your complexion without harshness
This serum is ideal for anyone struggling with dullness, melasma, uneven tone, or sun spots, which, let’s be honest, includes most of us at some point.
I’ve used it on all skin tones, from the fairest to the deepest, with beautiful results when customized correctly. It’s even suitable for sensitive skin, though you’ll want expert guidance to start slow and build up.
Will It Bleach My Skin?
Absolutely not. That’s not how real skincare works. PIGM 400 doesn’t strip, it refines. Your natural skin tone is beautiful.
This serum simply helps quiet the dark patches that are stealing the spotlight.
How To Use Serum PIGM 400 Without Wasting A Drop
When applying Serum PIGM 400, less is more. Use 4–6 drops, dispensing onto your fingertips, not directly on your face, for precision and control.
Press gently into areas with pigmentation like cheeks, forehead, or jawline. For full-face radiance, tap lightly across the skin without rubbing to avoid irritation and boost absorption.
This formula works best when left undisturbed. Its actives, like wasabi extract and sea lily, need time to settle in, so give it at least 60 seconds before layering other products. Sensitive skin? Apply in sections to monitor how your skin responds. Let your skin drink it in, calmly and completely.
🧠 Key Tips
Use it full-face if you want overall glow, or spot treat if you’re targeting specific marks.
Always massage lightly, your skin isn’t a punching bag. A light touch helps with absorption.
Store in a cool, dry place, refrigeration is even better to protect the actives. (Especially important if you’re using it slowly.)
Remember: skincare is like fitness. Doing too much at once doesn’t accelerate results, it just leads to burnout. Let your skin breathe between actives.
Building A Routine With Serum PIGM 400
Products alone don’t change skin, routines do.
When you use Serum PIGM 400 within the right framework, it’s not just another serum, it becomes a game-changer.
1. Cleanse With A Lait Cleanser
Start your day with one of our Lait Cleansers, each designed to gently purify without disrupting your skin’s balance.
Lait E.V. nourishes dry or mature skin.
Lait S.R. is perfect for oily or acne-prone types.
Lait Dermo-S calms sensitive or reactive skin.
These milky cleansers cushion the skin while prepping it for actives. No foam, no stripping, just a balanced, comfortable reset.
2. Tone With Lotion P50 PIGM 400
If pigmentation is a concern, Lotion P50 PIGM 400 is my go-to. It gently exfoliates without aggression and clears the path for your serum to work smarter. Start every other day if you're new to P50, then build up as your skin strengthens.
3. Apply 4–6 Drops Of Serum PIGM 400
Drop it onto your fingertips, not directly on your face. Press gently into skin, cheeks first, then forehead and chin. You can target pigmented areas or apply evenly for a full-face glow. Let it absorb fully before layering anything else.
4. Moisturize With Crème PIGM 400
Crème PIGM 400 is your brightening anchor, hydrating, silky, and filled with pigment-preventing actives. It’s light enough for the day, but effective enough to boost your results over time.
Finish With SPF (AM)
Your serum can’t work if UV rays undo your progress. We stock sunscreens that glide under makeup, don’t clog pores, and play well with deeper skin tones.
UVA rays hit year-round, even through windows, so treat SPF as your final skincare step, always.
Week By Week: What Really Happens When You Use Serum PIGM 400
Let’s set clear, realistic expectations, because transparency is part of what we do best at KarinaNYC.
Serum PIGM 400 is a powerful brightening tool, but it works gradually, not overnight. I’ve tracked client progress over years (yes, we take photos every two weeks!), and this is the general timeline I see:
Week 1–2: Early Signs Of Renewal
Your skin begins to feel softer, more hydrated, and balanced. A faint brightness emerges as tone improves subtly. Some notice smoother texture and reduced redness, early signs that PIGM 400 is supporting cellular renewal.
A bit of tightness or dryness? Totally normal. Stick with it.
Week 3–4: Pigment Begins To Lift
Superficial pigment, like sun spots or post-acne marks, starts to fade. Skin tone looks more even, and that dull, tired look starts to lift.
Week 6+: Transformation Deepens
Deeper spots, melasma, and age-related pigmentation begin to visibly fade. Skin appears firmer, smoother, and more radiant.
Complexion looks not just brighter, but more unified. This is when we may add Masque PIGM 400 or LED therapy to level up results. Trust the process.
Your Serum PIGM 400 Questions: Let’s Clear Them Up
You’re not the only one with questions about Serum PIGM 400, my clients ask them all the time. Let’s clear up the most usual concerns so you can use this serum with confidence and get the results you’re really after.
Where Does This Go In My Skincare Order?
Always after your exfoliating toner (like Lotion P50), and before your moisturizer. Think of it as the actives layer, close to the skin.
Can I Use This If I Have Rosacea?
Possibly, yes, but I always recommend starting slow. At KarinaNYC, we’ll often introduce it zone by zone, watching closely for sensitivity.
Does This Fade Freckles?
No, and that’s a good thing. This serum targets hyperpigmentation, not your natural melanin pattern. Freckles usually stay; what fades are the blotchy, uneven patches.
What If I Overuse It?
Using too much or too often can backfire. Your skin might get dry, irritated, or even rebel with new pigment. Stick to 4–6 drops, max, and listen to your skin.
Why Isn’t My Pigmentation Fading Fast?
Pigment takes time to lift. But if it’s slow, we look at things like:
Are you layering correctly?
Are you getting daily sun exposure without proper SPF?
Are you combining it with incompatible actives like aggressive acids?
Can I Use This With Retinol?
Yes, but never on the same night. Retinol and PIGM 400 are both potent, and overlapping can tip your skin into irritation. I often alternate nights for clients using prescription retinoids or retinol-based creams.
With the right guidance, most clients see a visible shift by week 4, but the real magic often happens between months 2 and 4. Patience here pays off big.
The Pigment Solution That Goes Beyond Just Products
If you’ve tried brightening serums before and nothing worked, you’re not alone.
I can’t tell you how many clients come to me after years of throwing money at “miracle” products that overpromise and underdeliver.
Serum PIGM 400 isn’t magic, but in the right hands, it delivers real change.
At KarinaNYC, we’ve seen clients fade long-standing melasma, sun damage, and stubborn post-acne marks by simply correcting two things:
Using the right product for their skin instant
Using it correctly within a properly sequenced routine
This serum works when it’s customized. That’s why we evaluate melanin response, skin behavior, and product interactions.
And yes, we track progress with photo evidence so you can actually see the shift.
Whether your concern is pigmentation from years of tanning, hormonal changes, or inflammation, this routine can work for you, if you’re ready to commit.
You’re already investing time, energy, and budget into your skin. Don’t let poor product guidance waste that effort. With the right partner, your skin will respond.
