Powerful antioxidant, protects against free radicals and promotes a radiant, even complexion.

As simple as that does lumen work

Four simple steps for your skincare routine

Moisten face & skin

Moisten face & skin

Thoroughly wet your face or the affected area of skin with warm water so that the soap spreads easily.

Lather & massage in

Lather & massage in

Lather Lumen between your hands or directly onto the skin and massage in gently for 2–3 minutes.

Allow to soak in

Allow to soak in

Let it sit for a moment so the kojic acid and turmeric can work on the skin.

Rinse & let dry

Rinse thoroughly. Store soap in a dry place afterwards; for best results, use 2–3 times per week.

Hear From Dr. Joeliz

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.

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.

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.
