antioxidant lightening concentrate with ultra-stable vitamin C 15%

99,06% ingredients of natural origin

Discolorations, uneven colour, dull complexion are no longer your problem! Using two vitamin C derivatives with the highest effectiveness, stability and bioavailability, we have created a product that will even out and protect your skin.

Active concentrate with a large dose of natural, ultra-stable vitamin C in two most modern forms. It not only brightens discolorations, but also prevents their formation. The use of two top-quality, high concentration vitamins guarantees hydration and effective antioxidant action, protecting the skin against free radicals and photoaging. In addition, it helps in the synthesis of collagen, restores firmness and elasticity of skin, and reduces wrinkles.


Vitamin C is one of the most effective antioxidants that neutralize the effects of free radicals. In addition, it strengthens the effect of SPF filters and protects the skin from the negative effects of radiation.

Ethylated vitamin C (3-O-Ethyl Ascorbic Acid 10%) demonstrates the lowest risk of skin irritation, while Ascorbyl Tetraisopalmitate (5%) is one of the most expensive and effective forms of vitamin C in the world. It is ultra-stable – it does not irritate or cause allergies. We combined them to get a creamy serum in the form of a concentrate that is phenomenally absorbed by the skin, leaving no sticky layer.


It will be appreciated by skin of all types, especially with discolorations, as well as by tired, dull and acne-prone skin.


Immediately: protection against free radicals and photoaging

4 weeks: skin hydration, reduced discolorations and fine lines

8 weeks: smoothing and restoring skin radiance, reduction of medium and deep wrinkles

Apply every morning and/or evening onto cleansed face and neckline skin, avoiding the eye area. Remember to use an SPF 50 product every day.

Storage: The product should be stored in a dry place, away from light sources, at a temperature of 15 to 25°C.

Potential allergic reaction to each cosmetic is very individual and depends on the condition of skin. If you are not sure whether a given product will cause allergic reactions, an allergy test before using it for the first time is recommended.

Frequently Asked Questions
Can GOOD TO C YOU be applied directly to bare skin in the morning without a toner or is it better to use it with a toner?
The concentrate is effective at the physiological pH of the skin, which often increases during facial cleansing. For this reason, the use of a toner is an essential step before applying GOOD TO C YOU.
Can I use this product while breastfeeding?
The concentrate is safe to use. For breastfeeding women, we recommend introducing it gradually, starting with one pump of the product every other day, and observing the skin's reaction. If there are no abnormalities, you can increase the frequency and use it every day. It is important to remember that the mother's skin during breastfeeding can be unpredictable. There is an increased risk of irritation, redness, itching or burning. Before introducing new products with active ingredients into your skincare, we encourage you to consult your doctor.
Can I use vitamin C concentrate in the morning and Focus Pigmentation in the evening? Does the vitamin C content in both products mean it is better to use only one of them in my skincare routine?
Such a combination is possible, but it is necessary to observe the skin's reaction – whether the amount of active ingredients is not too high or whether it does not react too strongly. FOCUS PIGMENTATION ESSENCE contains a complex of 7% AHA, so it is important not to use a large number of products with acids or retinoids with an exfoliating effect during the treatment.
Can I use products with retinal or acids while using GOOD TO C YOU?
Yes, if the GOOD TO C YOU concentrate was introduced earlier than retinoids or if you have already built up a tolerance to retinoids. When using both products in one skincare routine, we recommend applying a vitamin C product in the morning and a retinal product in the evening.
When is the best time to use this product?
You can use GOOD TO C YOU in the morning and/or evening skincare routine, depending on your needs.
Can I apply sunscreen or other cream on top of the product?
By all means! GOOD TO C YOU has been formulated to be used in combination with SPF creams. The delicate emulsion absorbs quickly and does not leave a greasy film, so you can immediately apply other products.
Can I use this product alone, instead of a cream?
The concentrate can be used alone or in combination with your favourite day or night cream. We recommend that you always finish your skincare routine with your favourite cream, as this will increase the absorption of the highly concentrated active ingredients into the deeper layers of the skin.
Can the product clog pores?
The risk of clogging depends on individual skin. If you have this problem, it is important to complete a thorough, two-stage cleansing of the skin. In addition, you should regularly use a peel (preferably enzymatic or acidic one), which will also help deeply cleanse the pores and prevent blackheads.
Does the product need to be refrigerated?
No, the product should be stored in room temperature (15-25°C), in a dry place, away from light sources.
What age group is this product for?
This product has been formulated for the needs of the skin regardless of age. Antioxidation is one of the basic elements of skincare and we recommend it to everyone, especially people over 25 years of age.
What vitamin C derivatives and in what concentration were used in this product?
Our product uses two of the most stable forms of vitamin C available on the market. 3-0-ethyl ascorbic acid – ethylated ascorbic acid at a concentration of 10% – is a water-soluble form of vitamin C, which protects the skin against free radicals and oxidative stress, supports the fight against photoageing, stimulates the synthesis of collagen and hyaluronic acid, lightens dark spots and evens out skin tone. Ascorbyl tetraisopalmitate, or ascorbyl tetraisopalmitate at a concentration of 5%, is a fat-soluble derivative of vitamin C. Its most important feature is its similarity to the hydrolipid barrier, thanks to which it penetrates deep into the skin, brightening and soothing it, preventing hyperoxidation and the formation of discolourations, and protecting the skin against the negative effects of UV radiation.
What are the benefits of combining these two types of vitamin C?
The combination of both types of vitamin C gives a spectacular antioxidant effect and has a multidirectional action, reducing existing discolourations and preventing the formation of new ones. As a result, the product works not only on the surface of the epidermis, but also reaches its deepest layers.
Why were these vitamin types combined in one product?
The product uses ultra-stable forms of vitamin C, which are compatible with each other and improve the effectiveness of the cosmetic product.
What can I combine this product with?
Vitamin C is best combined with peptides, trehalose, hyaluronic acid and SPF cream. If you are applying this product during the day, we recommend using it under an SPF cream, such as LET'S GLOW BB or DROP OF PERFECTION. In the evening, you can apply it underneath CERAMIDE SKIN BARRIER or REPAIR BY NIGHT.
What is the pH of the product?
The pH level of the product is between 3.8 and 5.8.
Can I use other forms of vitamin C with this product?
There is no need, as our product has a high concentration of the best vitamin C on the market, which ensures a comprehensive and optimal effect.
What are the best cosmetics to combine this product with?
If you are applying this product during the day, we recommend using it under an SPF cream. In the evening, you can apply it underneath CERAMIDE SKIN BARRIER or REPAIR BY NIGHT.
When is it particularly worth including vitamin C in your skincare routine?
Protection against free radicals is extremely important in your daily skincare routine and we recommend it to everyone. In addition, products with vitamin C are recommended when you notice loss of skin radiance, dull and greyish complexion, uneven tone, discolouration, age spots, loss of elasticity and the first signs of ageing. Cosmetics with vitamin C have a number of beneficial properties and guarantee visible results with regular use.
Can I use vitamin C products in summer?
There are no contraindications to the use of vitamin C in summer. We recommend using the product in combination with an SPF 50 sunscreen. The filters additionally prevent premature ageing of the skin.
Does the product have a fragrance?
The formula of the product contains fragrances.
Can the product cause allergies?
Side effects resulting from the use of the cosmetics are very rare, but they cannot be completely ruled out. They depend on the individual predispositions of the skin and the reaction may differ from person to person. We have taken this fact into account and formulated a natural concentrate with vitamin C, which is in line with the assumptions of the Clean Beauty philosophy and reduces the risk of allergic reactions.
What does the 3M symbol on the product packaging mean?
The PAO symbol – Period After Opening, also known as the open jar symbol, indicates the time after opening the packaging (from the moment the product is first used for its intended purpose) during which the product can be safely used.
What makes this product superior?
The use of natural, ultra-stable, compatible forms of vitamin C in very high concentrations, the effectiveness of which has been confirmed by application tests.
Why should the product be stored away from light sources in sealed packaging?
Vitamin C is sensitive to sunlight and oxidises quite quickly. For this reason, the packaging of the product is black and reflects sun rays.
Is vitamin C concentrate only effective with the right pH of the product?
This is a key parameter of products containing vitamin C in their formula.
