Electroporation for at-home skincare uses electrical pulses to temporarily create micro-channels in the cell membrane, allowing active ingredients to bypass the skin's normal barrier and reach deeper layers. The INIA SPHERA's INFUSE+ mode uses this technology, delivering up to +875% improved skin permeability versus manual application. But this applies only to compatible ingredients — understanding which work and which don't is essential.
Part 1. How Electroporation Differs from Iontophoresis
Iontophoresis (used in the INIA FLARE): Uses electrical charge to push ionic/charged molecules through the skin. Only works with charged active ingredients.
Electroporation (INIA SPHERA INFUSE+): Creates physical micro-channels in the cell membrane by disrupting the lipid bilayer with electrical pulses. Molecules pass through the channels independently of their charge — enabling neutral molecules, large molecules (peptides, HA, collagen fragments), and hydrophobic molecules (retinol) that iontophoresis cannot deliver.
🗣️ r/SkincareAddiction user: "I upgraded from a basic iontophoresis device to the SPHERA for exactly this reason — it can deliver retinol and peptides. My old device couldn't move those molecules at all. The difference in results using retinol with INFUSE+ vs without was noticeable after about 4 weeks."Part 2. Which Ingredients Are Compatible with Electroporation
| Ingredient | Electroporation Compatible? | Notes |
|---|---|---|
| Hyaluronic acid (HA) | ✓ Excellent | Large molecule; electroporation enables deeper delivery than topical alone |
| Peptides (palmitoyl tripeptide, copper peptides, etc.) | ✓ Excellent | Key electroporation advantage — neutral/large molecules iontophoresis can't move |
| Retinol | ✓ Compatible | Neutral form of vitamin A; start at 0.1%; electroporation increases effective potency |
| Niacinamide | ✓ Compatible | Water-soluble; neutral; works well in appropriate formulation |
| Antioxidants (CoQ10, vitamin E) | ✓ Compatible | Neutral molecules; benefit from deeper delivery |
| Collagen fragments / hydrolyzed collagen | ✓ Compatible | Smaller fragments can penetrate through channels |
| Vitamin C (L-ascorbic acid) | ✓ Compatible | Works in water-based serums; may cause mild irritation at high concentration |
| Face oils (pure oils, oil-based serums) | ✗ Not recommended | Hydrophobic; doesn't mix with aqueous tissue fluid; may block channel entry |
| Silicone-based primers | ✗ Not compatible | Forms occlusive barrier; prevents channel formation and entry |
| Acids (AHA/BHA at high concentration) | ⚠️ Use with caution | High-acid + electroporation can over-exfoliate; use only at low concentrations |
| Prescription retinoids (tretinoin) | ⚠️ Consult dermatologist | Deep delivery may increase potency significantly; reduce frequency with Rx strength |
Part 3. The Face Oil Question — Why Oils Don't Work
Electroporation creates hydrophilic (water-loving) channels in the cell membrane. The delivery relies on aqueous vehicles to transport actives through these channels. Oils are hydrophobic — they don't mix with water-based tissue fluid and can't be transported through hydrophilic channels. Additionally, oil on the skin surface can interfere with the electrical pulse itself, reducing channel formation effectiveness.
The workaround: Complete your INFUSE+ session with a water-based serum, then apply your face oil as the final step after the session. The oil will seal in the deeply delivered actives without interfering with the electroporation.
💡 Tip: For electroporation sessions, choose water-based or gel serums (water as first ingredient) over oil-based treatments. A lightweight hyaluronic acid serum, peptide essence, or niacinamide serum are all ideal formats for INFUSE+ sessions.Part 4. The Correct Application Order — Before or After the Device?
The correct order: apply product BEFORE activating INFUSE+ mode.
Electroporation creates transient channels in the membrane. The active ingredient must be present on the skin surface when the channels open. If product is applied after the channels have already closed, the delivery window is missed.
Correct SPHERA INFUSE+ protocol:
- Complete LIFT or TIGHTEN mode session (on clean, dry skin without product)
- Apply your chosen serum / essence to your face — spread evenly
- Immediately activate INFUSE+ mode — device passes over skin while product is present
- Channels open and product is driven deeper with each pass
- Follow with COOL mode if desired
- Allow 5–10 minutes before applying additional product on top
⚠️ Important: INFUSE+ should NOT be used on bare skin without product. The mode is specifically designed to drive topical ingredients deeper — without an active ingredient present on the surface, you are running electroporation with no payload. Always apply your serum first before activating INFUSE+ mode.Part 5. The Best Product Types for SPHERA INFUSE+ — Ranked
Tier 1 — Ideal:
- Hyaluronic acid serum (1–2% HA in water base)
- Peptide essence or serum (10–20% peptide complex)
- Niacinamide 5–10% serum (water-based)
- Retinol serum 0.1–0.3% (start low; electroporation increases effective potency)
- Multi-active serums combining HA + peptides + antioxidants
Tier 2 — Compatible with considerations:
- Vitamin C serums (10–20%): effective but can cause mild irritation at high concentration; start with 10%
- CICA / centella serums: excellent for sensitive skin; water-based format works well
- Collagen-boosting serums with hydrolyzed collagen
Tier 3 — Avoid during INFUSE+ sessions:
- Face oils, dry oils, oil-based serums
- Silicone-based primers or serums
- AHAs/BHAs at high concentrations
- Heavy fragrance-containing products
r/30PlusSkincare user: "I use a 2% HA serum + 0.2% retinol serum layered together before INFUSE+. The combination has made a bigger difference than either product did before I started using electroporation. My skin plumped noticeably within 3 weeks and the retinol results appeared faster too."Part 6. How COOL Mode Fits In
The SPHERA's COOL mode (cryotherapy at 15–16°C + calming blue light) follows INFUSE+ to help the skin calm down, reduce mild post-stimulation redness, and support recovery. Not mandatory, but recommended for sensitive or reactive skin.
The ideal sequence: LIFT or TIGHTEN → INFUSE+ (with serum applied) → COOL → allow 5–10 minutes → apply moisturizer.
�� Tip: If your INFUSE+ serum includes peptides and HA, you may not need to apply additional moisturizer immediately after — deeply delivered HA creates internal hydration. You can add moisturizer as a final seal 5–10 minutes later.Part 7. INIA Recommendation
The INIA SPHERA's INFUSE+ mode provides electroporation-based ingredient delivery that goes significantly beyond standard iontophoresis — enabling neutral and large molecules like retinol, peptides, HA, and collagen fragments that charged-molecule-only systems cannot deliver. Pair INFUSE+ with a peptide + hyaluronic acid serum for the most evidence-supported combination.

FAQ
Can I use the SPHERA INFUSE+ mode without any product?
No — INFUSE+ is specifically designed to drive topical ingredients deeper. Running it on bare skin activates the electroporation mechanism without any payload. Always apply your serum before activating INFUSE+ mode.
What is the difference between SPHERA INFUSE+ and FLARE iontophoresis?
FLARE uses iontophoresis — pushing ionic/charged molecules with electrical charge. SPHERA INFUSE+ uses electroporation — creating physical channels. Electroporation can deliver neutral molecules (retinol, peptides, HA) that iontophoresis cannot move effectively.
Can I use retinol with INFUSE+? Won't it be too strong?
Yes, but start low (0.1% retinol). Electroporation increases effective delivery — a lower concentration may produce stronger effects than topical use alone. Start low, monitor for sensitivity, and adjust from there.
How often should I use INFUSE+ mode?
1–2 times per week for INFUSE+ is typical. The skin needs time for channels to fully reseal and recover between sessions. LIFT and TIGHTEN modes can be used more frequently in the same routine.
Will electroporation deliver sunscreen ingredients deeper into my skin?
Avoid using INFUSE+ over sunscreen. Always use INFUSE+ on clean skin with a targeted active serum, not on skin with SPF applied.
Can I use peptide-rich eye cream around the eye area with INFUSE+?
The SPHERA should not be used over the eye area. The INIA LUMIN (XE) is the device designed for the periorbital zone.
Is there a risk of over-infusing an active with INFUSE+?
With strong actives (high-concentration retinol, strong acids), over-delivery is possible. Start with lower concentrations than you would use topically and monitor your skin's response before increasing.
