Barrier Booster Serum, 30 ml
A stop to skin turmoil - with our Ceramide Serum for your Barrier Boost What is this disrupted skin barrier that everyone is talking about and how can you recognize it? Red, irritated, flaky and rough - if this sounds anything like your skin, then your skin's protective barrier may be impaired and your skin microbiome out of balance. What your skin needs now is plenty of moisture and biotics. Curtain up for our Ceramide Serum. A whole 10% biotics - what can they actually do?Pre-, pro- and postbiotics are your skin microbiome's friends. The prebiotics inulin, probiotics black yeast ferment and postbiotics yeast fragments help to rebalance the skin's microbiome and form a natural protective shield against environmental influences. Wonderful if your skin's protective barrier is irritated or disrupted. And what does the 0.3% ceramide complex do? Ceramides are like bodyguards for your skin - they protect it, prevent moisture from escaping and keep the barrier function stable. Thanks to them, your skin remains resilient and nourished. Simply put: ceramides make your skin fit again! Have you read all of this and were puzzled by the term "microbiome"? Len wasn't sure exactly what it was at first and asked again. So he memorized the explanation: He imagines the microbiome (also called skin flora) of the skin as a lively small town that sits enthroned directly on the surface. Bacteria, fungi and yeasts bustle about here - tiny creatures that diligently sweep, protect and keep order. These mini-inhabitants are real all-rounders: they keep dirt slingers at bay, regulate the moisture balance and bravely defend the boundaries of the skin. And while Len enjoys his life, they toil away in the background and ensure that his skin is not disturbed. With our Ceramide Serum, you can help them do their daily work even better. Stronger together!

You're stressed and your skin even more so?Take a deep breath and say "Niaaaaaa-ciiiiinaaa-miiiideeee". Are you more relaxed yet? With this mantra, the niacinamides in our serum not only work on your skin, but also on your nerves. In relaxing harmony with the skincare miracle panthenol, the result is the perfect calming duo. Vitamin B12 is also added to the formula of our serum for a refined complexion and a soothed skin feeling. Poof - your skin is back in zen mode! What effect does 5% niacinamide in the serum have?Our serum contains 5% niacinamide, making it a real all-rounder in skincare. Also known as vitamin B3, we celebrate this active ingredient for its versatility. It refines the skin's texture, minimizes pore size, can even out uneven skin tone, smooth fine lines and wrinkles and regenerate the skin. Have we forgotten anything? Oh yes, niacinamide can also strengthen your protective barrier and give your skin a radiant complexion. A real over-achiever for your skin! What does the 1.3% provitamin B5 complex do for your skin?Hidden behind the cryptic vitamin name is one of the most ingenious active ingredients in skincare - panthenol. If you haven't heard of this evergreen yet, panthenol has a gentle moisturizing effect and can support skin regeneration. This makes it the perfect partner in Calm for the niacinamide in our serum. Panthenol is a real treasure, especially for dry, sensitive and irritated skin. Len's insider tip: Instructions for your daily (skin) meditation ritual When Len is stressed, there is one thing that is more relaxing than any singing bowl music or stress ball: facial yoga! The gentle massage movements on your face relax your facial muscles and promote blood circulation. Count how many times a day you raise your eyebrows in amazement and you'll know just how much tension is hidden there. For the best relaxation ritual, follow these simple steps: 1. Clear the sink2. Clean the mirror3. Apply Calming Serum with niacinamide and panthenol, chant your mantra and gently massage it in. Now nothing will upset you or your skin!

Glow Booster Serum, 30 ml
Who are these free radicals and what do they have to do with this vitamin C serum? Free radicals are little troublemakers that can wreak havoc on your skin barrier. When they buzz around and attack healthy cells, they can damage them. This in turn can lead to inflammation and premature skin ageing. What can you do about it? Use our vitamin C serum, for example! It contains a 2% resveratrol complex and 2% vitamin C, which can effectively trap and neutralize free radicals before they cause any damage. What does the 2% vitamin C derivative do? Our vitamin C derivative ethyl ascorbic acid is the leader of the "anti-free radical" cavalry! It blocks the nasty free radicals and also helps to boost your collagen. So it gives your skin's ageing process a friendly... okay, less friendly... kick in the butt! By the way: The derivative used is significantly more stable than pure vitamin C (= ascorbic acid) and therefore retains its effect. What can the 2% resveratrol complex do? The up-and-coming star in skin care heaven (encapsulated resveratrol) is delivered directly to the skin, where it unleashes its full active power. As a true antioxidant wonder, it protects your skin from nasty environmental influences and keeps premature skin ageing at bay. Attention, attention, this vitamin C serum has a nemesis! Okay, that's probably a bit harsh, but did you know that vitamin C and retinol don't like each other very much? Avoid combining these two active ingredients, because together they can irritate your skin too much. Instead, pair the vitamin C serum with a nourishing cream. Psst... we think your serum has fallen for our Essential Day Cream with SPF 30. Maybe you'd like to pair them up?

Hydrating Booster Serum, 30 ml
Watch out, it's getting deep! No, we're not making any confessions of love. However, the amount of gentle, deep-acting moisture contained in our Hyaluronic and Polyglutamine Hydrating Booster Serum definitely counts as proof of love for your skin. So what's so profound here? Well, the multi-molecular hyaluronic acid and polyglutamic acid in this serum, which penetrate your skin layers to different depths and intensively replenish moisture deposits. No more dry spells, because the formulation plumps up your skin from the inside and provides it with moisture for 24 hours. What can 0.5% polyglutamine in the serum do? Polyglutamine is a newcomer among moisturizers and has a lot of talents up its sleeve. The active ingredient is unbeatable when it comes to binding moisture in the skin. For a real long-term relationship between your skin and the moisture it loves so much. Polyglutamine also helps to increase the skin's natural moisturizing factor (NMF). We're already fans - and so are you? What does 0.2% hyaluronic acid do to the skin? When you say moisture, you must also say hyaluronic acid. It is not without reason that this active ingredient has long had a stage in moisturizing care. As a natural component of the skin, hyaluronic acid attracts and stores water. The result? Moisture is retained and the skin is given a firm appearance. Lens Skincare School: How different molecular weights work Active ingredients such as hyaluronic acid come in different molecular weights. These low, medium and high molecular weight active ingredients therefore penetrate your skin layers at different depths and can develop their effect there. This actively plumps up the skin from the inside out and fine, dryness-related wrinkles appear smoother.

Renewing Booster Serum, 30 ml
Robots in our retinol serum?No, retinoids are not robots from a distant galaxy, but effective vitamin A derivatives for your skin. In this serum, we use a 0.14% retinol derivative in combination with 1% vitamin E. While pro-retinol boosts skin renewal and reduces fine lines and first wrinkles, vitamin E protects the skin from oxidative stress and supports regeneration. This combination can also be a little miracle cure for blemish-prone skin, as it can help prevent pores from clogging. What is the 0.14% retinol derivative good for?As a vitamin A precursor, retinol boosts your collagen synthesis and therefore improves your skin's elasticity. Our serum is based on retinyl palmitate, a smart derivative of retinol. It offers all the benefits of pure retinol, but is significantly more skin-friendly. Only the best for you! Why 1% vitamin E?Vitamin E is a powerful antioxidant that protects the skin from free radicals caused by environmental factors such as UV radiation and air pollution. It has a calming effect, supports regeneration and helps to strengthen the skin barrier. In combination with retinol, it ensures optimal care - while retinol stimulates skin renewal, vitamin E helps to soothe and nourish the skin at the same time. Perfect for the nightYou're probably looking at this serum because you want firmer, healthy-looking skin overnight. Our Retinol Serum is specially formulated for use at night, so you don't have to worry about the nasty sun damaging your skin (vitamin A and UV radiation don't get along so well...). So, take your new serum to bed with you and sing along with us: "La, Le, Lu, only the retinoid is watching...".
