Skin conditions

Much more than just a vitamin C serum:
DEEP C is The multiactive AOX booster

Improved formula with 2% ferulic acid and 5% time-released vitamin C - making it even more effective and at the same time milder.

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.

HighDroxy DEEP C - now with improved formula - combines several antioxidants in optimal dosage to use their full care potential. The complex of vitamin C, resveratrol, ferulic acid, licorice extract and Szechuan pepper, together with other active ingredients, counteracts and gradually fades spots and discolorations when used regularly. With consistent use, redness, spots and discoloration can gradually fade and visually fade into the background. At the same time, the formula is particularly mild and suitable for all skin types.

Numerous studies have researched and proven the skin beautifying effects of antioxidants:

Reduction of inflammation and redness

Fade
from hyper-pigmentation

Strengthening of the skin's
protective barrier

Slowing down the aging of the skin

Improvement of the skin structure

Application

DEEP C is applied in the morning or evening after facial cleansing and preparation (toner) like a serum. We recommend the application in the morning.

Use DEEP C sparingly - it is highly concentrated and 1-2 pumps of the full size is enough (2-3 pumps of the Deluxe sample). Apply DEEP C as skincare step 3, that is, after you have mildly cleansed your face and applied a thin liquid product to prepare it (we recommend the CALM ESSENCE or the hyFIVE SPRAY). The skin may still be slightly damp, so DEEP C can be distributed even better.

Due to the pH skin-friendly formula, DEEP C can be combined with other care products without any problems, despite the vitamin C content, as long as they are pH skin neutral.

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

How high are the doses of vitamin C and ferulic acid in DEEP C ?
All the active ingredients listed are contained in relevant dosages in DEEP C . In contrast to high-dose monopreparations, for example pure vitamin C serums, the decisive factor in the development of this product was to optimally coordinate and sensibly combine the quantities of active ingredients. Vitamin C, for example, is dosed at 5 percent to ensure good tolerability even with daily use and sensitive skin. Vitamin C is water-soluble, but with regular topical application the skin can store it and thus build up a depot. Ferulic acid is included at 2 percent, which is the ideal concentration for use in cosmetics. More would not have a better effect, but only increase the irritation potential.

Which pigmentation disorders does DEEP C help with and which do not?
DEEP can help fade colored hyperpigmentation. These include the brownish or grayish age spots caused by excessive sun exposure, reddish pimple marks or other spots due to inflammation (also abbreviated PIH), or melasma, which can occur especially during or after pregnancy.
However, the active ingredients contained in DEEP C do not help with pigment loss (hypopigmentation). Here you should seek professional advice from a dermatologist.

How quickly will my pigmentation disappear if I use DEEP C ?
The darker a discoloration is tinted, the longer it will take to see initial results; here you should calculate in months rather than weeks. In the case of pimple marks, initial results are usually a little quicker to observe. In general, we recommend regular application, because only in this way can the melanin accumulations in the skin be gradually broken down.

Can I combine DEEP C with other HighDroxy products and if so, how?
DEEP C works in synergy with the classic active ingredients retinol, AHA and niacinamide. This means that these active ingredients support the care goal of DEEP C, i.e. the gradual weakening of discolorations. Thus, a combined application with the corresponding HighDroxy products RETINAID (Retinol), HYDROPEEL, FACE SERUM (AHA) or Niacinamide (hyFIVE Spray or Booster) is possible and recommended. As with all ingredient-intensive skin care products, be careful not to overdo it: If your skin is prone to sensitive reaction, it is recommended to apply alternately in the morning or evening, or even daily.

I have read that vitamin C is a sensitive active ingredient - what do I need to be aware of?
This information mostly refers to the pure form of vitamin C, ascorbic acid: it requires a low pH value and is sensitive to air and light. The form used in DEEP C is bound to gylcerin and is therefore more stable and, for many users:inside, more skin-friendly to use. The airless dispenser also protects the vitamin C from premature oxidation. A slight brown coloration on exposure to air (e.g. product residues at the dispensing opening) is normal and unavoidable.

I have very sensitive skin - is DEEP C suitable for me?
In principle, DEEP C has been developed for all skin types and also for the skin condition "sensitive". However, sensitive skin can manifest itself in many ways and also have very different causes. So it always depends on a test - for this purpose our deluxe samples are very suitable. By the way: Daily use is not mandatory, but regular use is.

I don't have pigmentation disorders or pronounced redness - what benefit does DEEP C have for my skin then?
DEEP C is not a "bleaching agent", but a skin care serum with antioxidant and anti-irritant properties. Therefore, it is recommended to use it even if you have a fairly balanced skin complexion. The antioxidant effect supports the body's own cell protection and thus prevents signs of aging. And discolorations in particular can already be "dormant" in the depths of the skin, even if they are not yet visible. Therefore, active ingredients such as tranexamic acid and vitamin C are always recommended for preventive use.

The smell of DEEP C is unusual - how come?
Because we at HighDroxy do not fragrance our products, the inherent odor of the ingredients is sometimes perceptible (by the way, this is exactly the reason why many brands sometimes heavily fragrance their products: to mask inherent odors). How exactly the scent is perceived, each nose feels differently. The ferulic acid in DEEP C has a characteristic odor of its own - many describe it as similar to cinnamon, others as more woody, and many are reminded of the classic "tiger balm" smell. Some perceive a woody note of Szechuan pepper. As you can see, olfactory perception is very individual.

Did you already know? Stains and discolorations are the real "old makers

This is shown in a study by the University of Göttingen: For this, 169 women aged 11 to 76 were photographed. Their portraits were then electronically adjusted for wrinkles without changing the other skin texture. These portraits were shown to female and male test subjects with the task of judging the faces according to age, health, youthfulness and attractiveness.
The clear result: the more homogeneous the skin, the younger and healthier the face was estimated to be! Interesting: When the test persons assessed the edited photos, the assessments of the women did not differ from those of the men - although only women's faces were shown. Everyone finds even skin beautiful.

PROVEN EFFICACY, RELEVANT DOSAGE: THE MOST IMPORTANT ACTIVE INGREDIENTS OF DEEP C

Orange slices arrangement

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-compatible and is also quite unstable. DEEP C 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 DEEP C more effective and gentler 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. In addition, it can help against redness due to its anti-inflammatory mode of action.

DEEP C uses 1% highly purified resveratrol - that's about 10x more than in many products that advertise this active ingredient.

Flower from licorice bush

Licorice extract: Clarifying and soothing

Licorice extract and the glycyrrhetinic acid it contains combine 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 berries on the bush

Szechuan pepper: Anything but hot to the skin

Szechuan pepper as a cosmetic active 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 to soothe small expression lines.

PROFIL TIPS TO DEEP C

The skin-balancing effect of DEEP C is wonderfully complemented by the active ingredients retinol, AHA and niacinamide. You will find the corresponding product recommendations below. Be careful not to overload your skin with too many active ingredients. An application in the evening change is often completely sufficient.

The antioxidants contained in DEEP C are wonderful boosters for your sun protection. In general, especially in case of hyperpigmentation, you should pay attention to a consistent (i.e. daily) UV protection in your day care. The DAY LIGHT 30 fluid or the D-FENCE 50 oil are recommended here.

Szechuan pepper extract is included in DEEP C for its skin-soothing and antipruritic effects. But it can do even more: studies indicate that it can temporarily soothe the muscles of facial expression and thus even out expression lines. This has been observed particularly in the crow's feet. Feel free to try it out - DEEP C is mild enough for application to the left and right of the eye.
