Description
Vitamin C serum with superfood extracts against pigmentation spots
For those seeking visible results from vitamin C — a more even complexion, fading of pigmentation spots, brighter appearance — but who have been disappointed by classic vitamin C serums in the past, there is good news. The oldest generation of vitamin C formulas based on pure ascorbic acid is notoriously unstable, often irritates the skin, and oxidizes within weeks into a brownish-pink, ineffective liquid. For users with sensitive skin or a damaged skin barrier, this has been a reason to give up on vitamin C entirely, despite its proven effect on pigment regulation.
Cosmedix Revert is formulated precisely for these users. The Boosting Brightening Serum works with tetrahexyldecyl ascorbate — a stabilized, lipid-soluble vitamin C derivative that works at a skin-friendly pH of 5-6 and gradually converts in the skin. No irritation, no oxidation, no burning sensation. Supplemented with a particularly broad plant spectrum: Kakadu plum, daisy flower (rich in L-arbutin), apple, pineapple, and fermented black tea for extra antioxidant action — a combination rarely found in any other vitamin C serum. The creamy texture absorbs quickly without pilling under moisturizer.

- Evens out uneven skin tone and dull complexion
- Protects against free radicals with antioxidants and botanicals
- Suitable for sensitive skin that cannot tolerate classic vitamin C
- Creamy texture that does not stick or pill under moisturizer
- Suitable for all skin types, morning and evening
Active ingredients
Tetrahexyldecyl Ascorbate (THD): The star of this formula and a fundamentally different approach to vitamin C. Unlike classic ascorbic acid — which works at low pH and often causes irritation — THD is a lipid-soluble derivative that works at a skin-friendly pH of 5-6. It blends with the skin’s natural oils and activates gradually as it is absorbed into the skin. Research shows that THD is absorbed up to 50 times more effectively through the skin than many other forms of vitamin C, with significantly less chance of irritation.
Kakadu plum extract (Terminalia Ferdinandiana): An Australian fruit with the highest naturally occurring concentration of vitamin C in the world — up to 100 times higher than in an orange. Corrects existing pigmentation spots and prevents new discolorations caused by UV exposure.
Daisy flower extract (Bellis Perennis): A European plant extract rich in L-arbutin — a natural tyrosinase inhibitor that suppresses melanin production. Works synergistically with THD for a broader spectrum of pigment regulation, especially effective on sun damage spots.
Apple and pineapple extract: Two fruit extracts that provide antioxidants and nourish the skin. Pineapple naturally contains the enzyme bromelain, which gently exfoliates and contributes to a smoother skin texture.
Cantaloupe melon extract: A less common plant extract in cosmetics, rich in antioxidants and superoxide dismutase — an enzyme among the most powerful natural protectors against free radicals.
Fermented black tea (Saccharomyces/Camellia Sinensis Tea Leaf Ferment): A kombucha-like ingredient rarely found in other brightening serums. Provides extra antioxidant effects and skin-soothing properties. A fermented ingredient that aligns with the modern fermented skincare movement.
Lemon extract (Citrus Limon): A natural source of vitamin C and mild fruit acids that refresh the skin and help regulate sebum. Contributes to a matte, refreshed appearance.
Cucumber extract (Cucumis Sativus): A traditional soothing ingredient that refreshes the skin and acts mildly astringent — helps regulate sebum without drying out.
Phragmites Kharka and Poria Cocos extract: Two Asian ingredients with antioxidant properties that contribute to a healthy-looking complexion. Connects to the Asian beauty tradition of plant-based skincare.
D-trehalose: A natural sugar known as a 'survival molecule.' Retains moisture in the skin under harsh conditions like dry air conditioning and cold wind.
Caprylic/Capric Triglyceride: A light plant-based lipid base that provides the beloved creamy texture — not watery like classic vitamin C serums, not heavy like oils, but velvety soft and fast-absorbing.

Frequently asked questions
Why is the vitamin C in Revert different from classic vitamin C serums?
Classic vitamin C serums usually use pure ascorbic acid — chemically the active form of vitamin C, but problematic in cosmetic practice. Ascorbic acid works at a low pH (around 3.5), oxidizes quickly when exposed to air, and can cause burning or redness on sensitive skin. An ascorbic acid serum that turns brown after a few weeks has largely lost its effectiveness. Revert uses tetrahexyldecyl ascorbate (THD), a lipid-soluble derivative that is exceptionally stable, works at neutral pH, and is gradually converted into active vitamin C in the skin — without the typical drawbacks of pure ascorbic acid.
Can I use Revert on sensitive skin?
Yes, it is formulated specifically for that. Those who have previously been unable to tolerate vitamin C serums due to burning, irritation, or redness will often tolerate Revert much better. The combination of THD's neutral pH with soothing botanicals (cucumber, daisy flower, pineapple) makes the formula gentle for reactive skin types. When in doubt, always perform a patch test on the neck first.
Does Revert protect against damage from blue light and screens?
Yes, this is one of Revert's specific uses. Research shows that blue light from screens (phone, laptop, tablet) contributes to premature skin aging and pigmentation — similar to UV damage, but through different pathways. The combination of THD with antioxidant-rich botanicals (fermented black tea, Kakadu plum, cantaloupe melon) neutralizes this damage. For people who work eight hours a day in front of screens, this is a targeted supplement that classic vitamin C serums do not provide.
How much Revert do I need per application?
One to two pumps for the entire face. The creamy texture is concentrated and a small amount is enough — more is not better in this case and can cause pilling under moisturizer. Start on the forehead, press down gently with your fingertips, and softly spread out towards the neck and décolleté. Gently tap the residue around the eye area.
What is the difference between Revert, Simply Brilliant, and BrillianCy?
Three different vitamin C/brightening options in the Cosmedix range. Revert works with tetrahexyldecyl ascorbate plus superfood botanicals — suitable for sensitive skin and blue light protection. Simply Brilliant is a water-based serum with ten actives, including niacinamide, lactic acid, and salicylic acid — more concentrated and exfoliating, better for less sensitive skin with stubborn pigmentation spots. BrillianCy is a facial oil with the same vitamin C derivative as Revert — suitable for dry and mature skin. The choice depends on skin type and desired texture.
Can I combine Revert with retinol or acids?
Yes. Unlike classic vitamin C serums, Revert has no compatibility issues with other actives due to its neutral pH. Typical routine: Revert in the morning followed by SPF, retinol (Define, Refine, Serum 16) in the evening. Or Revert both morning and evening, with retinol on specific nights of the week. Niacinamide-containing moisturizers like Shineless or Harmonize combine particularly well with Revert.
Can I use Revert during pregnancy or breastfeeding?
Yes. The formula contains no retinoids, salicylic acid, or other ingredients that are discouraged during these periods. Vitamin C derivatives are generally considered safe during pregnancy and breastfeeding — and Revert is an excellent choice for pigmentation regulation during these times, especially when melasma first appears. Consult your midwife if in doubt.
When will I see the first results from Revert?
The immediate brightening effect is noticeable within a few days — the skin feels softer and looks more vibrant. For visible improvement of pigmentation spots, age spots, and uneven skin tone, daily use for eight to twelve weeks is recommended. Pigmentation spots are the most stubborn concern in skincare and require consistency — no brightening serum works without daily SPF.
How long does a 30ml bottle last?
With daily use (one to two pumps per application), a bottle usually lasts two to three months. When used both morning and evening, this comes to one and a half to two months. The pump bottle doses precisely and keeps the serum fresh — important for a formula with active antioxidants.
