Uneven complexion, dark spots, tired skin that you cover with concealer instead of actually treating? No. 03 — Lumen combines turmeric and kojic acid in a gentle hand soap that targets the root cause of pigmentation spots instead of just masking them. Used two to three times a week, it supports a more even, radiant complexion – for face and body, sulfate-free and gentle on sensitive skin.
Kojic acid is one of the most well-researched plant-based active ingredients for treating hyperpigmentation. A randomized comparative study (Deo et al., 2013, Indian Journal of Dermatology) examined 80 patients with melasma over several weeks: Kojic acid was proven to inhibit tyrosinase activity – the enzyme responsible for melanin production – and reduced visible pigment spots. Important for an honest assessment: the study tested a leave-on application overnight; with soap that has a short contact time, the effect is milder and requires more patience.
Turmeric (curcumin) has anti-inflammatory and antioxidant properties. A systematic review (Vaughn, Branum & Sivamani, 2016, Phytotherapy Research) evaluated 18 clinical studies, 8 of which focused on topical application to the skin. The evidence for pure pigment reduction is promising but still limited – the studies were predominantly small. The most consistently documented benefit is its anti-inflammatory effect, which calms irritated, uneven skin and supports the action of kojic acid.
Realistic timeframe: initial pleasant sensations after about 1 week, first visible changes after 4–6 weeks, established routine after about 3 months.
Yes, when used externally as intended. Kojic acid may cause mild sensitivity in some people – we recommend testing it on a small area of skin before first use. If irritation occurs, pause use. Not suitable for contact with the eyes; in case of contact, rinse thoroughly with water. As with all skin-brightening active ingredients: use additional sun protection during the day, as the skin may be more sensitive to UV radiation. Not intended for children.
1. Moisten face or affected area with water 2. Lather Lumen between hands 3. Gently massage for 2–3 minutes, especially on affected areas 4. Rinse thoroughly with clear water 5. Use 2–3 times weekly (not daily) 6. Apply moisturizer afterwards and use sun protection during the day

As simple as that
does lumen work
Four simple steps for your skincare routine
1
Moisten face & skin
Thoroughly wet your face or the affected area of skin with warm water so that the soap spreads easily.
2
Lather & massage in
Lather Lumen between your hands or directly onto the skin and massage in gently for 2–3 minutes.
3
Allow to soak in
Let it sit for a moment so the kojic acid and turmeric can work on the skin.
4
Rinse & let dry
Rinse thoroughly. Store soap in a dry place afterwards; for best results, use 2–3 times per week.

Clinically tested
In a randomized comparative study with 80 participants (Indian Journal of Dermatology, 2013), kojic acid was proven to inhibit tyrosinase activity and reduce visible pigment spots. A systematic review of turmeric (Phytotherapy Research, 2016) evaluating 18 studies further confirms the anti-inflammatory and skin-soothing effects of turmeric.
Activated bamboo charcoal binds excess sebum and impurities deep within the pores.

I've been struggling with acne marks for years and have tried so many things. After about 5 weeks with Lumen, the dark spots have really faded. To be honest, I wouldn't have expected that from a soap. I also find the scent incredibly pleasant.

I had really bad dark spots on my cheeks after my pregnancy. I'm now in week 7 and see a clear difference. Not completely gone, but much more even. I use it 3 times a week as recommended.

I have been using the soap for almost three months now. The dark spots on my forehead and cheeks have become noticeably lighter. The soap is very mild, with no redness or irritation. For me, the purchase was worth it.

I didn't really expect much, I just wanted something for the uneven patches on my neck. After 4 weeks: skin texture is better overall, feels smoother. The spots are still there but definitely less noticeable. Ordering the 6-pack now.

I have spent years trying various creams for my age spots, many of them with ingredients that only irritated my skin. Lumen is pleasantly mild, and I have seen an improvement after about eight weeks. It’s great that there is something like this available as a soap, too.

I’ve been using this on my acne marks around my chin for a month and wow. They aren’t completely gone, but they’re so much better. My roommate even asked me what I’m doing differently. It also smells really nice, like turmeric.

Use the soap for the dark spots on your forearms. After two weeks, they are a bit lighter but still visible. As I said, though, it’s only been two weeks. The quality is top-notch, and my skin feels well-nourished. I’ll keep at it and provide another update.

Since taking the pill, I've had melasma on my upper lip and cheeks. For years, I didn't dare go out without foundation. I'm now at week 10 with Lumen and it has faded significantly. I am so relieved that something is finally working.

A colleague told me about it. I have been using the soap for two months now for the dark spots on my hands. They have become visibly lighter. The soap is moisturizing and goes a long way. I immediately ordered the 9-pack.

After the summer, I had a pretty uneven tan and a few dark spots on my face. I've been using Lumen for about 5 weeks and it is visibly evening out. It lathers well, doesn't dry out my skin, and has a subtle scent. I am satisfied.

At my age, you’ve collected quite a few spots. I have been using the soap for three months now, three times a week. My skin feels nourished, and some spots have actually become a bit lighter. I will continue using it.

I had post-inflammatory hyperpigmentation after a bout of acne and it just wouldn't go away. After 8 weeks of using Lumen, most of them are significantly lighter. I ordered 6 bottles right away because I know I'll be using them long-term now.

After my pregnancy, I had dark spots on my forehead and above my lip. I tried so many things. I’ve been using Lumen for 2 months now and the difference is incredible. Not perfect, but so much better that I feel comfortable again without having to cover everything up.

Frequently Asked Questions
Is Lumen suitable for sensitive skin?+
Yes. Lumen is sulfate-free and formulated to be mild. Kojic acid may cause a slight tingling sensation on very sensitive skin initially — we recommend performing a patch test on a small area of skin before the first use. If irritation occurs, pause use.
When will I notice a difference?+
Initial pleasant sensations of use are often felt after just the first week. Visible changes to skin texture generally require 4–6 weeks of regular use (2–3 times per week). For a significant difference, we recommend at least 3 months.
Can I use Lumen daily?+
We recommend 2–3 applications per week. Daily use is possible, but may lead to irritation if you have sensitive skin. Less is often more here — consistency over weeks counts for more than frequency.
Does the soap dry out my skin?+
No. Lumen contains shea butter, glycerin, and olive oil, which nourish and moisturize the skin. Nevertheless, we recommend applying cream as usual after use.
Does Lumen also work preventively, or only once pigment spots are already present?+
Both. Kojic acid inhibits tyrosinase activity and can thus also help reduce the formation of new pigment spots. With regular use, existing spots can become lighter. Important: use sun protection during the day, as UV radiation is the primary trigger for new pigmentation.
