At a glance:


A troubled skin appearance with pigment spots and discolorations can have a more negative impact on the visual appearance than wrinkles and lines. The causes of this hyperpigmentation and redness are primarily micro-inflammation and skin stress at the cellular level, caused by oxidative processes. Both can lead to pigment accumulation in the skin as well as visible irritation.

Antioxidants (AOX) are essential in an active-based skincare routine for this reason, as they protect the skin from these cell-damaging processes and micro-inflammation.

Vitamin C is the best-known antioxidant, but in its pure form (as ascorbic acid) it is often not suitable for sensitive skins.

DEEP C relies on a particularly skin-friendly form of vitamin C in the optimum dosage of 5% and supplements this with other proven antioxidants such as resveratrol and ferulic acid.

Together with anti-inflammatory licorice and soothing Szechuan pepper extract, the BRIGHT C+ BOOSTER counteracts spots and discoloration with regular use and gradually fades existing hyperpigmentation. The mild formula is suitable for all skin types.

Please note the slightly stronger inherent odor of this formula, which is perceived differently from nose to nose. Experience has shown that this disappears quickly after application.

Application & ingredients


The BRIGHT! C+ BOOSTER is preferably used in the morning after cleansing and preparing the face (toner) like a serum.

For preparation we recommend the BRIGHT! LIQUID. The skin may still be a little damp so that the booster can be spread even better.
Thanks to the pH skin-friendly formula, the BRIGHT! C+ BOOSTER can be easily combined with other skincare products despite its vitamin C content, as long as they are pH skin-neutral.

We advise you to use a sunscreen daily to prevent new discolorations.

Does not stick, very well tolerated. The smell takes some getting used to. I find it better than other vitamin C serums. But it's a matter of taste. Tip: Order a sample first

The perfect complement to the BRIGHT! C+ BOOSTER is the BRIGHT! LIQUID. This complexion-balancing toner liquid combines the advanced tranexamic acid with other brightening active ingredients.

Tranexamic acid has been tried and tested in clinical dermatology for a long time. This is because it lightens a wide variety of types of pigment spots - and does so as effectively as the active medical ingredient hydroquinone. 

In the liquid, it is supplemented with niacinamide and licorice, as well as special whitening peptides from pea and quinoa.

To the Bright! LIQUID

Vitamin C Retard (5%): The active classic. Only better.

Vitamin C has been considered the gold standard in the dermatological treatment of hyperpigmentation for decades. This is because it has been scientifically proven that vitamin C inhibits the production of the skin pigment melanin and can thus attenuate acquired (i.e. not congenital) hyperpigmentation. But classic vitamin C (ascorbic acid) is not very skin-friendly and is also quite unstable. The BRIGHT! C+ BOOSTER therefore uses one of the most modern forms of vitamin C, which is significantly more stable and is released into the skin with a time delay (retard effect). This makes the vitamin C in BRIGHT! C+ BOOSTER more effective and gentle than conventional ascorbic acid.

Ferulic acid: the perfect partner for vitamin C

Ferulic acid is also a powerful antioxidant that occurs, for example, in the cell walls of oats, rice or apples, but is produced synthetically for cosmetic purposes and is thus particularly pure.

Studies show that ferulic acid optimally supports and enhances the effect of vitamin C - among other things, by helping the vitamin C to penetrate deeper into the skin. In addition, ferulic acid can inhibit the formation of new blood vessels under the skin and thus reduce redness...

Resveratrol: The fountain of youth from the red grape

Resveratrol is also often referred to as the "youth molecule" - for good reason: It is one of the most powerful antioxidants and thus counteracts the processes responsible for skin aging at the cellular level. Additionally, it can help combat redness due to its anti-inflammatory mode of action. BRIGHT! C+ BOOSTER uses 1% highly pure resveratrol - that's about 10x more than in many products that advertise this active ingredient.

Licorice extract: clarifying and soothing

Licorice extract and glycyrrhetinic acid contained in it combines anti-inflammatory, antibacterial and antioxidant properties. In addition, it inhibits the enzyme tyrosinase, which is involved in the formation of melanin in the skin. Thus, glycyrrhetinic acid is also able to reduce hyperpigmentation.

Szechuan pepper: Anything but hot to the skin

Szechuan pepper as a cosmetic ingredient is anything but spicy to the skin. On the contrary, it soothes the skin and helps to reduce itching. In addition, it has relaxing properties, which means it can help soothe minor expression lines.


Combine brightening active ingredients

The BRIGHT! LIQUID can be wonderfully combined with other complexion-balancing active ingredients. For example, the C+ BOOSTER from the same range, or mild exfoliating products such as CALM SENSIPEEL.

Exfoliation accelerates the removal of excess skin pigments.

Use UV protection consistently

UV radiation stresses your skin not only in summer, but all year round. And your skin reacts to this stress by forming pigment cells.

It is therefore particularly important for the treatment of pigmentation spots to use a daily care product with UV protection - for example our DAY LIGHT 30.

Please be patient

Pigment spots do not appear overnight - and therefore do not fade within a few days.

The reduction of melanin deposits in your skin is a gradual process. However, with consistent use of skin-lightening active ingredients, you will see results.
