01 / Brightening and Antioxidant Therapy with Vitamin C
The first three steps: prep and exfoliation
The session runs 60-90 minutes. It starts with Vitality Cleansing Fluid for makeup removal, then Prime Cleansing Gel for a deep cleanse. Step three is key, the Skin Perfection exfoliating mask sits 10 minutes before we wash it off with light circular motion for extra mechanical exfoliation of the stratum corneum. That clears the path for the vitamin C serum in the next step, without exfoliation, vitamin C stays on the surface layer and works with reduced efficiency. Toning with Definitive Glow Toner Highline closes this phase and balances pH before the actives. Sensation so far: light warmth and pleasant tightness; the enzymes work slowly with no sting, so even sensitive skin tolerates this step.
The heart of the therapy: 20% and 10% Vitamin C
Now the real work. C-Radiance Serum with 20% Vitamin C is worked in with light massage until fully absorbed. We recommend ultrasound or non-invasive mesotherapy if you have device access, those increase L-ascorbic-acid penetration by 30-40%. L-ascorbic acid at 20% is close to the maximum the skin tolerates in one session. This is a relatively high-percent serum, you may feel a one-minute sting, especially around the nose and lips. Five minutes later comes the C-Restore mask with 10% Vitamin C, which sits for 12-15 minutes. The mask nourishes and neutralises any sting at the same time. Many clients feel a "pulse" in the skin here, that is the vitamin C actively working and blocking tyrosinase. Vitamin C works as both an antioxidant and a melanogenesis inhibitor, that is why a single session delivers both glow and slight tone evening.
Wrap-up and right after
The last steps are 4D Intensive Fluid for the eye contour and Vitamin C Pro Expert SPF50 cream, non-negotiable, because vitamin C makes the skin more UV-sensitive in the first 24 hours. Right after the procedure you will see clear brightening, a more even tone, and firm, radiant skin. The tone reads "awake" and brighter for 24-48 hours; peak effect lands on day 2-3, when vitamin C kicks in cell turnover. Texture is smoother and pores appear smaller for about 5-7 days. You can continue your day with no visible signs of a procedure, makeup is fine right away, though the first 2 hours are better spent letting the skin breathe. A light flush is normal; if you have active rosacea, see our dedicated rosacea protocol. Vitamin C keeps working in the epidermis for 48-72 hours after application, that is exactly why a course with a 10-14 day interval is the optimal strategy. Glow is visible immediately, but tone evening and pigmentation reduction come with build-up. Before you leave, the specialist will recommend the right vitamin C serum for home use, usually 5-10% for sensitive skin, 15% for more resilient. Read also who it is for and the aftercare plan. The full protocol is on the therapy page; all protocols, in the catalog. For pigmentation, see the pigmentation page.
Active concentrations
The active profile of Vitamin C therapy includes: L-ascorbic acid 20% (serum) and 10% (mask), niacinamide, ferulic acid, vitamin E. Each concentration is chosen for a specific function, not for marketing impact. Higher concentrations do not mean a stronger result: above a certain threshold the skin starts to reject the actives or to respond with inflammation. So we work in the range where clinical studies show the best benefit-to-tolerance ratio. In-salon actives are at higher strengths than home-use ones because in the studio a specialist watches the skin reaction minute by minute and can stop or neutralise as needed. Home concentrations are more conservative, the goal is daily use without supervision. That is also why the two regimens are not interchangeable: the professional session gives a pulse, the home care reinforces and extends the effect. If you are wondering whether you can recreate the in-salon effect with stronger products at home, no. Not only the concentration but also the delivery method (ultrasound, iontophoresis, manual technique) determines penetration depth and the real outcome. For the complete product list we include in this therapy, see the therapy page.
Frequent questions from our clients
Beyond the three FAQs above, here are a few more questions we often hear at consultations. How many days before an important event should I book? Ideally 3-5 days, the skin has time to pass through the effect peak and to settle into its best look. The day before is not ideal, a mild flush, if it shows up, can take up to 24 hours to clear completely. Can I do a session during my lunch break? Only the shorter no-downtime protocols, usually dMS Cellular Awakening and Vitamin C. Sharper therapies need at least an hour of recovery after the session. What should I do if I feel discomfort a few hours after the session? First: a cold compress cloth for 5 minutes and a panthenol cream. If the discomfort does not ease within 4-6 hours, call us. Never apply retinol, acid, or a scrub on irritated skin, they will make the reaction worse. Can I keep taking supplements (collagen, biotin, omega-3) before and after the session? Yes, they support the effect from within. The only exception is high-dose vitamin E (over 400 IU daily) if we are planning injectable procedures. Is there an age limit? Lower bound, 18 with parental consent; upper, none, provided the skin is healthy enough and you have no contraindications. We have regular clients over 70. Can I show up to the session wearing makeup? Yes, we will remove it carefully with an appropriate cleanser; you do not need to arrive bare-faced if you are coming straight from work. Can I book a session while menstruating? Yes, but in the reactive phase (the 3 days around and after ovulation and the first 2 days of the cycle) the skin can react more strongly; if you can choose, schedule outside those days for a more predictable outcome. Can I bring my own products to include in the session? Only if they are from the system we work with, or if we have already approved them at the consultation. Mixing third-party formulas with our actives can produce an unpredictable reaction. How long is the consultation before a first session? 15-25 minutes, skin assessment, goal discussion, current home routine and medical history, patch test if needed. For the full therapy catalog and details see our protocols.
Technique and equipment
For Vitamin C therapy we use a combination of ultrasound, non-invasive mesotherapy, iontophoresis. Equipment selection is not random, each device works on a different mechanism and brings a different benefit to the actives. Ultrasound creates micro-vibrations at 1-3 MHz that push larger active molecules (peptides, exosomes) through the stratum corneum and increase penetration by about 30-40% compared with manual application. Iontophoresis uses a low electric current (1-3 mA) that temporarily opens micro-channels in the lipid matrix between cells and lets ionised actives (vitamins, niacinamide, certain peptides) reach deeper layers. Radiofrequency energy (RF) heats the deeper epidermis to 38-40°C, which triggers collagen-fibre contraction and stimulates fibroblasts to new production. Cryotherapy reduces redness, tightens pores, and reinforces active retention. In our studio the specialist decides which devices to include in your session based on skin type, goal, and tolerance. Not every device suits every skin profile, power and dwell time are always set individually. That is why two clients doing the same therapy in the same studio can get slightly different results, the settings are personalised. See the full therapy catalog in our protocols.
Common mistakes to avoid
We often see clients arrive with expectations that do not match what Vitamin C therapy actually does, and small mistakes that reduce the session result. Mistake one: expecting a once-and-done effect from a single session, no professional therapy works that way, not even the most aggressive ones. A single session holds for a specific window; afterwards the skin gradually returns to baseline; lasting change shows only with a course and maintenance. Mistake two: introducing strong retinol or an AHA peel at home in parallel during the first week after the session, the two active signals collide and the result drops instead of doubling. Your skin does not understand more is better, it processes one strong pulse at a time and stops responding to the next. Mistake three: skipping SPF50 in the first days after the session, literally every professional therapy loses 30-50% of its effect without UV protection, because peptides, vitamins, and exosomes are broken down by ultraviolet light. Even on a cloudy day the UV index is high enough to undo part of the in-salon work. Mistake four: scheduling the session the day before an important event, most protocols peak on day 2-3, not immediately; book 3-4 days ahead if you have a specific day you want to look your best. Mistake five: swapping half of your home routine right after the session, your skin works with the products it already knows; if you want to add new ones, do it after the first 7 days and one at a time so you can tell what is working and what is not. Mistake six: skipping the consultation before a first session, without a skin diagnostic (density, reactivity, tone, active history) the specialist works blind and the protocol gets adjusted mid-way instead of from the start; this reduces first-session efficiency by 20-30%. Mistake seven: not following the recommended interval between sessions in the course, a shorter one overloads the skin with actives, a longer one breaks the cumulative effect. Mistake eight: not drinking enough water in the days around the session, peptides and hyaluronic acid only work in a well-hydrated matrix; under dehydration the session result is flatter because the actives cannot hold moisture.

Frequently asked questions
Does the 20% vitamin C sting?
A short, mild sting is possible for about a minute, especially around the nose and lips. If you are very reactive, we can start with the 10% mask first and bring 20% serum back in a later session.
How often should I book?
A course of 4-6 sessions every 10-14 days, then monthly maintenance. Vitamin C compounds, a single session gives 7 days of glow, but real tone evening comes with a full course.
Is it suitable for acne?
For mild to moderate acne, yes. For active papules and pustules choose the Deep Cleansing Therapy first and add vitamin C afterwards as maintenance.
