The Leitin Skincare Pigment (LSP) System combines two advanced formulations designed to address pigmentation from both its earliest triggers and its visible manifestations.
Hyperpigmentation is far more than a dark spot on the surface. Long before pigment becomes visible, everyday stressors such as UV exposure, inflammation, pollution, and oxidative stress can trigger the skin's melanocytes to produce excess melanin.
This is why an effective pigmentation strategy goes beyond simply fading existing spots. It requires a two-pronged approach: helping protect the skin from the triggers that activate pigmentation in the first place, while also targeting the pathways responsible for excess melanin production after they occur.
Serum 1: LSP Defence Serum provides an advanced antioxidant defence network that helps neutralise oxidative stress, reduce inflammatory signalling, and protect against the environmental triggers known to activate melanocytes and initiate the pigmentation cascade.
Serum 2: Lumina Serum delivers a concentrated complex of melanocyte-regulating peptides and clinically studied brightening actives that work throughout the pigmentation pathway to disrupt melanocyte signalling, regulate MITF expression, inhibit tyrosinase activity, and reduce excess melanin production.
Together, these complementary formulations provide a comprehensive approach to pigmentation management, helping defend against the triggers that lead to discolouration while visibly improving the appearance of existing dark spots, uneven skin tone, and pigmentation concerns.
Aroma: Fragrance free
Suited To: Suitable for all skin types including dry, and mature skin types.

Launching November 16, 2026
We are preparing to launch LSP Defence Antioxidant Serum, the first formula in our upcoming two part LSP Pigment System. LSP Defence focuses on pigment defence, using advanced antioxidants to neutralise oxidative stress and interrupt melanocyte activation before pigmentation begins.
It will be followed by LSP Renewal, designed to regulate and protect the skin once melanocytes have been triggered. Across the two formulas, the system delivers 24 actives at clinical doses targeting multiple pathways involved in visible pigmentation. Ahead of launch, we will conduct a limited round of consumer testing.
LSP Lumina Serum
Melanocyte Control
LSP Lumina Serum
A more targeted approach to pigmentation begins with the cells behind it.
At the heart of Lumina, LSP NONALUME Complex brings together nine encapsulated ingredients designed to help regulate the activity of melanocytes - your skin’s pigment-producing cells.
Targeted peptides and complementary brightening actives address multiple stages of the pigmentation process, helping to interrupt pigment-stimulating signals and limit excess melanin production. Rather than focusing on a single pathway, the complex takes a coordinated approach to improving the appearance of dark spots and uneven skin tone.
For a clearer, more even and luminous complexion over time.

Defence Complex
This formula brings together a constellation of advanced antioxidant, anti-inflammatory and melanocyte-modulating actives, each selected to target a different stage of the pigmentation cascade. Catalytic antioxidant enzymes help neutralise reactive oxygen species such as superoxide radicals before they can trigger cellular stress, while potent polyphenols defend against singlet oxygen, lipid peroxidation and inflammatory signalling.
Alongside this antioxidant network, targeted pigment-regulating actives work to interrupt the communication pathways that stimulate melanocytes, helping to reduce the activation of MITF, tyrosinase and other key mediators involved in melanin production.
Rather than focusing solely on existing pigmentation, this multi-layered defence system is designed to address the earliest biological triggers of discolouration by reducing oxidative stress, calming inflammation, supporting the skin's intrinsic antioxidant reserves and helping to prevent the signalling events that ultimately lead to excess pigment formation.
EUK-134
EUK-134 is a potent self regenerating antioxidant enzyme mimetic designed to replicate the activity of two of the body’s most important protective enzymes, Superoxide Dismutase (SOD) and Catalase. These two enzymes neutralise Superoxide a harmful form of ROS.

These 2 products together are a powerhouse. Have noticed my pigmentation is fading significantly , the longer I’m using it. It’s been about 5 / 6 weeks so far and it’s going well. My skin is very luminous. LOVE IT

It’s only been a few weeks now and have noticed a significant amount of fading on a large pigment patch on my face. Like they say … skin care is a marathon not a sprint but this stuff is definitely doing it’s job

Dear Leitin, I absolutely love your products thankyou. The LSP serum is again a winner Issues that i have is that there are so many products to apply, and it can be quite time consuming (due to some products needing absorbson time) and i lose tract of what products i have applied and which i haven't. I love being part of your research. I have noticed that there is now a 3% copper peptide on the market now just fyi. Kind regards Jo

This product is definitely working, my skin tone is evening out and texture is grand, thanks Leitin!!
Store owner replied: Hi Wendy, So happy to hear you're seeing results this early on. Thank for you for taking the time to review The LSP Pigment Serum, and for being apart of our consumer trials.
I have been testing this product and have been so impressed. This feels so nice on application and it is surprising to see how far 2 drops ( 1 of each mixed) can spread. It’s still early days but so far I have experienced no adverse reactions & as someone with very reactive fair skin & rosacea that alone is encouraging. My skin is loving all Leitin’s products and looks so much better.

Really enjoying the serums, they absorb well, no irritation whatsoever and I’m still using my other skincare whilst following the plan given to me by Leitin. I’m currently part of the trial for these new serums and im loving them so much I’ve already ordered more. It’s only been a couple of weeks of use but my skin is looking clearer, I can’t wait to see results after 6 weeks
Store owner replied: Hi Stacey, Thank you so much for sharing your experience! 💕 We’re thrilled to hear you’re loving the serums and that they’re fitting so well into your skincare routine.

The system is so easy to use and the serums are very hydrating. I have only been using them for a few weeks but my skin is looking a little brighter already. I can't wait to see what the next few weeks brings.

Hi Leitin, I am doing an indepth review with pictures - which I will publish on tiktok and happy for you to use. But I have used this everyday for 2 weeks and I will repurchase. I love the texture, and I love the fact it does not have a scent. Those 2 things are very important to me. I have seen a mild improvement already I cant wait to see the rest. Thanks
