6 Week Eczema Relief Treatment Plan with Soteri Skin's Starter Kit
Soteri Skin’s Advanced Eczema Treatment 2-Step Topical Kit is the only non-steroidal eczema topical solution on the market that actively adjusts and controls your skin’s pH at the optimal 4.7 level for long lasting eczema relief.

Use pH/LOCK® Lite for 2-3 weeks
Begin with pH/LOCK® Lite for 2 weeks to allow skin to acclimate. Designed for active flares, redness, and irritation, it restores barrier function while minimizing sensitivity. Apply twice daily—morning and evening—after cleansing, before makeup or sunscreen.
If prescribed a steroid cream, apply it first. Over time, steroid reliance may be reduced as pH/LOCK® provides sustained control. Mild tingling can occur initially and typically resolves within a few days.

Transition to pH/LOCK® Eczema Relief Full Strength
After 2–3 weeks, transition to pH/LOCK® Full Strength. Clinically proven to correct and stabilize skin pH at 4.7, it delivers measurable relief of eczema symptoms within 4 weeks. Apply twice daily after cleansing, before makeup or sunscreen. If using a steroid, apply it first.
Keep Your Skin Eczema-Free with pH/LOCK®
pH/LOCK® is intended for continuous use to maintain long-term skin health. By sustaining optimal pH and supporting a balanced microbiome, it reduces recurrence of flare-ups and reinforces the skin’s protective barrier.
• Replace your daily moisturizer to ensure lasting barrier stability and symptomatic control.

Frequently Asked Questions33
Many users notice improvements within the first few days of Step 1 — including reduced redness, soothed irritation, and less itchiness.
In a clinical study, 60% achieved complete symptom relief (itching, redness, and flare-ups eliminated) within 4 weeks of Step 2.
For best results, apply twice daily (morning and evening, always after showering). Avoid layering other moisturizers, as they may disrupt pH balance.
No. Use them in sequence:
- Step 1 (first 2 weeks): Gentle formula for flare-ups, helps skin adjust.

Soteri Skin carries the National Eczema Association Seal of Acceptance, proving it's suitable for eczema-prone skin.
Yes — mild tingling is normal on irritated or flaring skin and shows the pH/LOCK® technology is working.
As skin heals, tingling fades. Start with Step 1 if flaring or new to Soteri, then transition to Step 2 for long-term repair.
Yes. If prescribed, apply the steroid first, wait 5 minutes, then apply Soteri.
Note: Topical steroids are usually limited to 2 weeks/month. Soteri is safe for daily use to help reduce steroid reliance.
Apply twice daily (AM & PM, always after showering).

We recommend using Soteri alone. Traditional moisturizers (like Vaseline® or CeraVe®) have higher pH levels that may interfere with results.
Soteri uniquely restores pH to 4.7 and keeps it balanced for 12 hours, strengthening the barrier against flare-ups.
No — our products are free from Propylene Glycol, Decyl/Coco/Lauryl/Cetearyl/Alkyl Glucosides, and other common allergens.
Formulas are designed for eczema-prone skin: no harsh surfactants, only safe, clinically tested ingredients.
Some users report improvements in hydration and barrier function. However, Soteri is formulated for eczema, where results are most significant.
Yes — we use 99 - 100% pure Niacinamide (Vitamin B3):
- Baby + Step 1: 0.5%
- Step 2: 1%
Niacinamide boosts renewal, strengthens the barrier, reduces redness, and locks in hydration.
