1 What is multi-layer hydration?
Multi-layer hydration is an in-clinic skincare treatment that delivers water and moisture-retaining ingredients into several skin layers at once: cleansing so the skin absorbs well, hydrating the epidermis, supporting the deeper layers when needed, and then sealing in moisture on the surface.
Skin holds water through two mechanisms: natural humectants within the cells (such as hyaluronic acid and the natural moisturizing factor) and the lipid film in the stratum corneum, which prevents water from evaporating. Regular moisturizing mainly works on the surface. Multi-layer hydration addresses several levels at the same time: removing old surface cells, using a device to help hydrating serums penetrate deeper, soothing the skin, and finally applying a moisture-sealing layer.
The goal is not just "plump, dewy" skin for a few hours after treatment, but a healthier skin barrier that holds water better on its own in the days that follow.
Surface layer (stratum corneum)
Cleansing away dead skin cells and sebum so the skin can breathe; finishing with a moisturizer to seal in hydration and reduce water loss through the skin.
Epidermis
Iontophoresis with a hydrating serum and a mask help replenish water and humectants in the cell layers.
Deeper layers (when indicated)
For long-term dehydrated skin, the doctor may consider a skinbooster or mesotherapy injection to deliver HA into the dermis.
Skin barrier recovery
LED light therapy and soothing products help reduce redness, support recovery and keep moisture in for longer.
2 Signs your skin is dehydrated and needs hydration
Skin that feels tight after washing, fine flaking, fine lines that show clearly when you smile, makeup that looks cakey, dull skin and easy redness or stinging are signs that your skin is dehydrated and its protective barrier is weakened.
Dehydrated skin is different from dry skin. Dry skin lacks oil and is usually constitutional. Dehydrated skin is a temporary condition that can affect any skin type, including oily skin. When dehydrated, oily skin may even produce more sebum to compensate, so you can look shiny and feel tight at the same time.
- Spending many hours a day in air-conditioned rooms.
- Hot sun, sea wind, spending a lot of time outdoors.
- Washing your face too often, using harsh cleansers, exfoliating frequently.
- Using acne or melasma products with drying active ingredients.
- After laser, peels or other procedures that cause the skin to shed.
If your dehydrated skin also has inflamed acne, lasting redness or itching, see a doctor to rule out dermatitis or irritation before starting a treatment.
3 What are the steps of multi-layer hydration at Foxy M.D?
The process includes a skin analysis, deep cleansing, intensive hydration with iontophoresis or Aqua Peel as indicated, a mask, soothing Celluma – PDT LED light therapy, and finally moisturizer and sunscreen. The steps are chosen according to your skin condition.
Not everyone goes through every step. Sensitive skin skips exfoliation and sebum extraction; skin with inflamed acne needs the acne treated first. Learn more about each step in our articles on Aqua Peel deep cleansing and Vitamin C & HA serum iontophoresis.
Aftercare: on the day of treatment, avoid heavy makeup, saunas and strong sun; keep moisturizing and using sunscreen regularly to maintain results.
Consultation and skin analysis
Assessing hydration, sensitivity and acne condition to choose the right steps.
Makeup removal and cleansing
Makeup removal and face washing; gentle exfoliation (not applied to skin with inflamed acne).
Deep cleansing
Aqua Peel extracts sebum and cleans pores when the doctor recommends it, preparing the skin to absorb.
Intensive hydration
Iontophoresis of a hydrating serum with the O+ Glowskin device helps nutrients penetrate better.
Mask and LED light therapy
A hydrating mask combined with Celluma – PDT light helps soothe and support recovery.
Moisture sealing and sun protection
A moisturizer suited to your skin type and sunscreen before you leave.
4 How does multi-layer hydration differ from an at-home mask and skinbooster injections?
At-home masks mainly hydrate the surface, with short-lived effects. Multi-layer hydration combines deep cleansing, devices that aid absorption, and recovery care. Skinbooster injections deliver HA into the dermis for a deeper, longer-lasting effect, but they are an invasive procedure.
These three options complement rather than replace each other. At-home moisturizing is the daily foundation; multi-layer hydration gives a "boost" when the skin is weak; skinboosters are for skin that has been dehydrated for a long time and shows early signs of aging. See more in our article on mesotherapy for glowing skin.
| Criteria | Masks and moisturizing at home | In-clinic multi-layer hydration | Skinbooster injections |
|---|---|---|---|
| Layer treated | Surface | Surface and epidermis | Dermis |
| How it is done | Do it yourself | Deep cleansing, iontophoresis, mask, light | Micro-injections, with numbing cream |
| Sensation | Comfortable | Comfortable, may feel slightly warm | Mild soreness, possible needle marks |
| When results show | A few hours | Right after the session | After a few days to a few weeks |
| Suitable for | Daily maintenance | Dehydrated or dull skin, after procedures | Long-term dehydrated skin, fine wrinkles |
5 Who should and shouldn't have multi-layer hydration? How often?
It suits people with dehydrated or dull skin, skin recovering after laser or peels, or anyone preparing for an important event. People with skin infections, severe inflamed acne or acute dermatitis need treatment first. The treatment schedule is suggested by the doctor based on your skin condition.
Consider multi-layer hydration if you have:
- Tight, slightly flaky skin, makeup that doesn't sit well.
- Dull, tired skin after late nights or working in air conditioning.
- Dry skin from an ongoing acne or melasma treatment.
- A wish for fresher skin before an event, a photo shoot or a trip.
Treatment first or extra caution is needed if you have:
- A skin infection, open wounds or facial herpes.
- Severe inflamed or cystic acne: the acne needs to be treated first.
- A flare-up of atopic or contact dermatitis.
- An allergy to serum ingredients: tell the doctor before treatment.
As for frequency, mildly dehydrated skin can be treated every few weeks at first, then less often for maintenance. The doctor will suggest a specific schedule after seeing how your skin responds.

10 Frequently asked questions
1. What is multi-layer hydration?
Multi-layer hydration is an in-clinic skincare treatment that replenishes water and locks in moisture across several layers of the skin. It usually includes deep cleansing, iontophoresis with a hydrating serum, a mask, LED light therapy and a moisture-sealing step. The specific steps are chosen based on your skin condition after a skin analysis.
2. Does oily skin need multi-layer hydration?
It may. Oily skin can still be dehydrated, especially if you spend a lot of time in air conditioning or use drying acne products. When skin lacks water, the oil glands often produce more oil to compensate. Restoring enough hydration helps the skin stay more balanced, but lightweight, non-comedogenic steps and products will be chosen.
3. Does multi-layer hydration hurt?
The cleansing, iontophoresis, mask and light steps are usually comfortable and may feel slightly warm or cool. Sensitive skin may sting a little during deep cleansing. If the doctor also recommends a skinbooster or mesotherapy injection, a numbing cream is applied first and you may feel mild soreness.
4. How often should you have multi-layer hydration?
The frequency depends on your skin condition. Clearly dehydrated skin is usually advised to have sessions a few weeks apart at first, then spaced further apart for maintenance. The doctor checks how your skin responds after each session and adjusts accordingly. Alongside this, you still need to moisturize and use sunscreen at home to maintain results.
5. Can you wear makeup right after a hydration treatment?
Ideally, let your skin rest on the day of treatment and avoid heavy makeup so freshly cleansed pores don't get clogged again. If the session included micro-injections, it is even more important to avoid makeup for at least the first day. You can still apply sunscreen when you go out.
6. Multi-layer hydration or skinbooster injections: which should you choose?
If your skin is temporarily dehydrated, dull or recovering from a procedure, multi-layer hydration is usually enough and gentler. If your skin has been dehydrated for a long time, with fine wrinkles and thin skin, the doctor may consider a skinbooster for a deeper effect. The two treatments can be combined as recommended.
