The first 24 hours
Stay out of direct sun for 24 hours and apply SPF50 every 2-3 hours under exposure. No AHAs, BHAs, or retinol for at least 48 hours, vitamin C is already a serious active and we do not want to overload the barrier. Makeup is fine from the same evening; skip scrubs and face brushes for 5 days. Morning: gentle gel, panthenol or 5-10% vitamin C serum from your home series, hydrating cream, SPF50. Evening: cleanse, hydrating serum, a richer cream. Sauna and tanning beds, off limits for 48 hours; heat speeds up vitamin C oxidation in the epidermis. Sleep on a clean pillowcase and swap it on day 3; skin after a session is more vulnerable to bacteria. Hydrate from within too, at least 1.5-2 litres of water a day, especially in the first 48 hours. See also what happens in the cabin. On this day SPF is not symbolic, UV radiation literally breaks down vitamin C in the epidermis within hours and undoes the session result. Pro Age Reset SPF50 or the Vitamin C Pro Expert SPF50 cream are the best picks because they pair with the in-studio actives. Avoid perfume and essential oils on the face for the first 24 hours, they can trigger a phototoxic reaction when combined with vitamin C and sun.
Days 2-7: extending the glow
From day two add a 10-15% vitamin C serum in the morning (for example the 15% Vitamin C Intensive Serum), it "reinforces" the work of the 20% from the studio. From day 5 you can reintroduce retinol in the evening, starting at two nights a week. A hydrating mask twice a week is a good idea too. SPF50 is non-negotiable, without it vitamin C oxidises within days and the result disappears. Vitamin E serum in the evening is also a good idea, vitamin E pairs with vitamin C and strengthens the antioxidant protection. Store the vitamin C serum in the fridge in opaque packaging, oxidised vitamin C (with a yellow-brown tint) has already lost its activity and may cause mild oxidative stress instead of protection. Avoid combining it with products containing copper or iron in active application, they speed up oxidation. Niacinamide and vitamin C in a single application can leave the skin briefly flushed; split them into two separate moments.
After the first week
The effect holds for about 7-10 days after a single session. If you are on a course, the next session is at 10-14 days, exactly enough time for the vitamin C from the previous session to complete its cycle in the epidermis. After the first session expect visible glow; after the third, noticeably more even tone; after the full course of 4-6 sessions, stably even tone and visible reduction of surface pigmentation. Vitamin C does NOT remove dermal pigmentation (chloasma, melasma), those need a medical approach. A shorter interval taxes the skin with actives; a longer one breaks the cumulative effect. From day 14 you can bring back the AHA peel once a week. For candidate profile and contraindications see the "Who it is for" article. Between sessions pair with the Ultra Intensive Hydrating Therapy or DMS "Cellular Awakening". Vitamin C works cumulatively, a single session gives a quick visible result, but real tone evening and reduction of pigmentation comes after 4-6 sessions. Monthly maintenance after the course is optimal. For daytime defence apply a low-percent vitamin C serum in the morning and SPF50 on top, together they block over 90% of UV-driven oxidative stress. All DMS, lifting, and peeling therapies, in the catalog. For daily antioxidant protection see the sun protection page.
Day-by-day timeline, detailed
For those who want a precise plan, here is the detailed first-two-weeks timeline after the session. Day 0 (the session itself): after returning home avoid hot water, exercise, and unnecessary face touching; evening routine, gentle gel cleanser, soothing serum, hydrating cream; sleep on a clean pillowcase. Drink a glass of water before bed to keep hydration up through the night. Day 1 (morning): cleanse with light motion, apply a panthenol or hyaluronic acid serum, hydrating cream, SPF50; evening, serum per the specialist recommendation, a richer cream. If you feel light tightness, layer a second cream 30 minutes later. Day 2: if you still feel tightness, add a second layer of hydrating cream at night; a hydrating mask once this week, today or tomorrow. Moderate workouts are fine now; steam and sauna are not. Day 3: the session effect usually peaks; you can add a low-percent vitamin C serum in the morning (5-10%) if your skin tolerates it. This is the day you will get the most compliments on your skin, make the most of it. Day 4-5: continue the routine without new products; if you plan to bring back retinol, do it with a first dose (two nights a week) from day 5 or 7 depending on the therapy type. From day 5 you can add a short morning lymphatic drainage massage (3-5 minutes with light circular motion from the centre of the face outwards and upwards), it reinforces microcirculation. Day 6-7: the effect fully stabilises; if you are on a course, the next session is at day 7-14 depending on the protocol. From day 7 you can gradually bring back an AHA peel once a week, start at a lower concentration (5-7%) and watch the reaction. Day 8-10: peak visibility fades gradually, the skin still looks more 'worked', plumper, and glowy. This is also when you can introduce a single new product (but not two in parallel). Day 11-14: the effect returns to baseline if you are not on a course; if you are on a course, this is exactly when the next session lands for most protocols. This plan is conservative, most clients can follow a more relaxed pace after the first 48 hours, but with sensitive skin it is wise to stick to it strictly. If you have doubts about a particular day, message or call us; better to ask than to drop a product that is actually working.

Data from our practice
Over the past year more than 200 clients went through the studio for Vitamin C therapy, either as a standalone session or as part of a course. About 78% report a visible improvement after the first session, usually in the category of brighter, plumper skin. Around 62% continue with the full 4-6 session course; of those, more than 85% report stable retention of the result for 2-3 months after the last session. About 12-15% do not see a meaningful effect after the first session, usually skin with a very thin barrier, dehydration, or parallel use of strong actives at home that pull from the effect. In those cases we re-assess and usually swap or pair with another protocol. These are internal consultation numbers, not a clinical study, we share them because we believe realistic expectations are the best foundation for a decision. About 4-5% report a mild adverse reaction (redness past 24 hours, brief tightness, small papules), usually a sign of a parallel strong home active or an undetected allergy. We have never had a severe adverse event from this therapy in our practice. Detailed contraindications and candidate profile are in the who-it-is-for article.
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.
