WHY IT'S SPECIAL
Your skin's microbiome may be compromised. Many skincare products disrupt the bacterial balance with harsh preservatives like parabens and phenoxyethanol, combined with overly acidic pH levels. This damages your skin's barrier, reducing its ability to absorb even high-quality serums.
Triple C Serum takes a different approach. Instead of forcing brightening ingredients through a damaged barrier, we restore barrier integrity and microbiome balance first. Our triple vitamin C complex then penetrates deeply through both oil and water pathways to target dark spots, hyperpigmentation, and uneven tone at the cellular level.
Our Phytoclinical Fitzpatrick Formulation™ took three years and 15-20 iterations to develop: maximum-strength actives in a stable formula that supports beneficial bacteria rather than destroying them.
Microbiome balance - Clinically tested to cause 0% disruption to skin's bacterial ecosystem
pH-calibrated to ~5.0 - Matches healthy skin's natural balance (most products are 3.0-4.5)
Triple Vitamin C complex - Uses dual oil/water pathways for deeper penetration into target cells
Microbiome-friendly preservatives - Support beneficial bacteria instead of eliminating them
Clinically validated on 3D human skin models - Tested for objective results across all skin types and tones. Dermatologist-approved.
When your skin's ecosystem is balanced, absorption improves, and results follow.
KEY INGREDIENTS
Our Triple C Complex combines three forms of Vitamin C:
Tetrahexyldecyl Ascorbate - Oil-soluble, stable Vitamin C

A Gut Pharmacist's Quest To Save Her Daughter’s Skin
"13 years ago, my daughter was born with a rare skin condition no one could solve. As a Doctor of Pharmacy, I became obsessed with understanding why some ingredients helped while others hurt.
At 40, my skin declared war - breakouts, dark spots, hyperpigmentation hit. No medical-grade, natural, or prescription product worked.
Until I connected my gastroenterology work: skin problems aren't about the ingredients. They're about the ecosystem.
Your skin is like your gut. It has a microbiome evolved over 200,000 years that decides whether it’s healthy or not.
Most women think inflammation, pigmentation and dark spots are just part of aging. It’s not. It’s a side effect of modern life - and it’s 100% reversible.
Now at 48, my skin is better than ever, and it has been that way consistently since using these products."
See The Results For Yourself
Triple C Serum has helped customers address dark spots, uneven tone, and hyperpigmentation.
The Science
THE MICROBIOME CRISIS™
Your skin works like your gut - when good bacteria die, absorption stops.
Modern life and traditional skincare commit bacterial chaos and destroy your skin’s microbiome with parabens, phenoxyethanol, and wrong pH levels.
Now your skin's locked shut like a damaged gut. Over time, melanocytes produce pigment chaotically. Dark spots multiply. Sudden breakouts happen.
OUR PHYTO CLINICAL FITZPATRICK FORMULATION™
Took 3 years and 15-20 iterations per formula to achieve the impossible: maximum-strength actives in a stabilised formula that supports beneficial bacteria. We spent $40,000 proving this synergy works - maintaining pH 5.0, preserving your microbiome, while delivering clinical-grade actives deep into the skin.
Fix the ecosystem, unlock absorption, watch everything transform.
$40,000 Study, Not “95% Saw Results”
Many skincare brands use subjective consumer surveys claiming "95% saw results." We take a different approach, investing over $40,000 per formula in objective clinical testing on 3D human skin models. After 15-20 formulation iterations, each product is validated in specialized labs that measure microbiome disruption, barrier integrity, and hydration at the cellular level. This is measurable, scientific validation, not dubious marketing claims.

Key Ingredients
Our science team brings 15 years of pharmaceutical R&D experience, backed by $40,000 in clinical studies and 17 formulation cycles. We've mastered synergistic formulation, where restoring barrier function unlocks deeper penetration, allowing clinical-grade ingredients to work effectively without causing irritation.
AMLA
Amla (Indian Gooseberry) contains 20 times more vitamin C than oranges and has been used in Ayurvedic medicine for centuries. Rich in antioxidants, it addresses multiple skin concerns while working both topically and internally.
Here are the primary benefits of amla for your skin:

Loved it
I loved this product! I thought that the price was a little steep when I first got it but once I received it and started using it I think it’s priced just right. The container is a heavy glass that feel really luxurious and the product itself is amazing. I’m a breast feeding mama so when it comes to anything ingredients are super important to me. Since plantkos has plant based and clean ingredients it’s totally friendly for expecting moms or breast feeding moms! I really liked that this product had hyaluronic acid in it because after putting it on my skin immediatly felt more hydrated. A lot of serums leave your skin feeling sticky or glossy but what is so nice about this serum is it leaves your skin matte. I would rate this product a 9/10!

C serum
This serum is just a must have. Wow! It is super hydrating and lightweight. This is the one serum that i kept using and it kept reducing inflammation. I was so excited to receive this product! As an esthetician and a beauty junkie, I love skincare and unique ingredients that will get you thinking and doing more research! Phyto is such an amazing brand and i loved every single one of the products that I received. It is great for all skin types in my opinions and truly delivers what it claims. It is hydrating and smoothing. The price is also amazing and the packaging is adorable with the red color. The products are gentle, I never felt scared or skeptical about using this brand that was new to me. But i enjoyed it so very much and give it a 5 star rating.

Triple C Serum
Plantkos Phyto Triple C Serum has become my skincare care bestie. This lightweight serum, with its rapid absorption, brings a powerful blend of three forms of vitamin C and hyaluronic acid into play. The results have been nothing short of impressive.The serum's efficacy in fading dark spots has been a standout feature for me. Consistent use has visibly improved the tone and texture of my skin, leaving it with a radiant and even complexion. I appreciate how it doesn't just target dark spots but also works towards providing a lasting hydration boost. The inclusion of hyaluronic acid ensures that my skin feels not only clearer but also remarkably supple and moisturized.If this Plantkos ever branches out into body care I’d really like this as a body serum.

FAQs
What causes dark spots on your face, and what are the different types?
Dark spots result from excess melanin production, leading to uneven pigmentation. The three main types are dark spots (from post-acne inflammation or aging), hyperpigmentation (from various factors that increase melanin production), and sun spots (from UV exposure). Our formula restores barrier function and microbiome balance first, allowing our active ingredients to penetrate deeply into targeted cells for more effective treatment.
How is this different from other serums?
Many serums use harsh preservatives that disrupt your skin's microbiome and then attempt to force ingredients through a compromised barrier. We prioritize restoring your skin's ecosystem and barrier function first. This allows active ingredients to penetrate effectively and deliver visible results.
How long does it take to see results?
Most customers notice improvements within 2-3 weeks, with significant changes by week 4. Because we restore barrier function first, active ingredients can penetrate more effectively, leading to faster visible results.
Is this suitable for sensitive skin?
Yes. Our formula is clinically proven to cause 0% irritation and is calibrated to pH ~5.0 to match healthy skin (most products are pH 3.0-4.5, which can trigger inflammation). Some customers may experience mild purging in days 3-7 as the skin rebalances—this is temporary and indicates the restoration process is working. If you have very sensitive skin, start using once daily and gradually increase to twice daily.
Does this work for age spots?
Yes. Age spots form when cellular damage causes melanocytes to malfunction and overproduce pigment. Our formula restores barrier integrity and supports microbiome balance, allowing active ingredients to penetrate deeply. When your skin's ecosystem is balanced, melanocytes receive proper signals to produce pigment evenly. Clinical studies show this barrier-restoration approach addresses underlying cellular dysfunction, not just surface symptoms.
Does this work for sunspots?
Absolutely. Sunspots occur when UV damage triggers an inflammatory response that causes melanocytes to produce excess pigment. Our Phytoclinical Fitzpatrick Formulation restores barrier function and microbiome health, allowing active ingredients to penetrate deeply. With a healthy ecosystem, your skin stops defensive pigment overproduction and begins normal cellular turnover, addressing the inflammatory root cause.
Who can use this serum?
Everyone. Our formula is dermatologist-approved for all skin types, tones, and sensitivities. Whether you have oily, dry, sensitive, or melanin-rich skin, our microbiome-friendly formula supports rather than irritates.
Does this work for melasma and stubborn dark spots?
Yes. Our clinical studies demonstrate efficacy across all skin tones, including for melasma treatment. Unlike harsh treatments that can worsen melasma through inflammation, we address the underlying barrier dysfunction that makes spots persistent.
Can I use it if I don't have hyperpigmentation?
Absolutely. Prevention is easier than correction. Even without visible dark spots, our serum improves overall skin health, hydration, texture, and radiance.
Can I use this with retinol, niacinamide, or other actives?
Our microbiome-friendly formula can work well with other products because we restore barrier function rather than compromising it. Many customers see improved results from their entire routine. However, if you're using retinol, we recommend alternating—use one product in the morning and the other at night.
