What normal irritation looks like
- · Mild redness for a few hours to a day.
- · Small raised bumps around follicles for 24 hours.
- · Warmth like mild sunburn for a few hours.
- · Slight tenderness or itchiness in the first day.
- · Small "ingrown-looking" bumps during the shedding phase (days 7–14).
The rule of thumb
If it feels like mild sunburn and improves each hour, it's normal. If it feels sharper, worsens, or spreads, call.
Home care that helps
- · Cool compresses for the first several hours.
- · Fragrance-free moisturizer 1–2x daily.
- · Pure aloe vera gel (no additives) if soothing helps.
- · Loose, breathable clothing over the area.
- · Skip heat, sweat, and sun for 48–72 hours.
- · OTC acetaminophen or ibuprofen for soreness.
When to call your provider
Same-day call for any of the following:
- · Blistering of any size.
- · Pain that persists or worsens after 24 hours.
- · Redness that spreads outside the treated area.
- · Signs of infection: warmth, pus, fever, spreading tenderness.
- · Any reaction that doesn't feel like normal healing.

How to prevent it next time
If a session leaves you with more irritation than usual, tell your provider before the next one. Common adjustments include lowering fluence slightly, extending the pulse width, or shifting timing (avoiding treatment right before big sweat or sun days). A small settings tweak usually eliminates repeat irritation entirely.

Key takeaways
- · Most irritation resolves in 24–48 hours.
- · Cool compresses and fragrance-free moisturizer are the mainstays.
- · Don't apply hydrocortisone or antibiotic ointment without provider guidance.
- · Blistering, spreading redness, or infection signs = same-day call.
- · Prolonged redness usually means settings need a small adjustment next session.
