What “safe” usually means
- Safe for most people: when you rinse it off and keep contact time short.
- Main risk is irritation: not “toxicity.” If your barrier gets dry, you can get redness or stinging.
- Consistency matters: start slow so your skin can adjust.
Common side effects
- Dryness or tight feel
- Redness or stinging
- Itchy rash (for some people)
Who should be extra careful
- Very sensitive skin or eczema
- Skin that is already irritated (too many actives, recent peel, over-scrubbing)
- Using multiple strong products at once (acids, retinoids, scrubs)
- Do not use on open cuts or irritated flare-ups.
How to use it safely (simple rules)
- Patch test: small area first, wait 24–48 hours.
- Start slow: 2–3×/week, then increase only if calm.
- Short contact time: face about 20–30 seconds to start, then rinse fully.
- Moisturize after: every wash.
- Use SPF 30+: daily on exposed skin to protect progress and help keep dark spots from looking worse again.
Stop and reset if you get swelling, hives, intense burning, or a rash that does not settle.
