Isntree Onion Newpair B5 Ampoule 50ml

Isntree Onion Newpair B5 Ampoule: Repair-Forward Ampoule for Irritated Skin

The Isntree Onion Newpair B5 Ampoule combines onion bulb extract (rich in quercetin and sulfur compounds) with 5% panthenol (vitamin B5, pro-vitamin form) in a single repair-focused ampoule. At $23.20 for 50ml, this is one of the most affordable entry points into post-procedure or barrier-repair ampoule territory. The formula targets irritated, reactive, or flare-prone skin that needs concentrated calming without heavy occlusion.

Onion skincare sounds unusual but has legitimate scientific basis: onion extract (specifically Allium cepa) contains high concentrations of quercetin, a flavonoid with anti-inflammatory and antioxidant properties. Dermatology-grade onion extract (Contractubex) is used clinically for scar healing. At 5% panthenol, the ampoule hits the dermatology-recommended concentration for visible barrier support and wound-healing acceleration.

What It Does

Quercetin from onion extract reduces inflammation and provides antioxidant support, which calms reactive skin and post-procedure irritation. Panthenol (converted to pantothenic acid in skin) supports cellular turnover, barrier lipid production, and has mild anti-itch effect. Combined in a watery ampoule format, the effect is fast calming with cumulative barrier strengthening over 2 to 4 weeks of daily use.

Who It's For

• Post-procedure recovery: Safe after laser, peels, microneedling.
• Reactive or rosacea-prone skin: Quercetin's anti-inflammatory action is meaningful.
• Retinol flare recovery: Calms irritation during retinol acclimation.
• Post-acne scar healing support: Onion extract has long-standing scar-healing use.
• Budget barrier repair: Significantly cheaper than most repair ampoules.

How to Use

Apply 3 to 4 drops to clean skin morning and night. Follow with moisturizer. During active flares or post-procedure recovery, use 2 to 3 times daily for the first week. Layer with heavier occlusive creams at night for enhanced barrier recovery.

FAQ

Does it smell like onion?

No. The onion extract is purified and deodorized, and the formula has a neutral clean scent. The only onion trace is slightly savory if you smell directly in the bottle, but not on skin.

Is it safe for sensitive skin?

Yes, and specifically designed for it. The formula avoids common irritants and uses barrier-supportive actives. Patch test if you're extremely reactive, but most sensitive skin tolerates this well.

Does it work on old scars?

Moderately. Onion extract has best effect on new or recent scars (up to 6 months post-wound). Older, established scars respond less. For old scars, combine with retinol or microneedling protocols for better results.

How long until I see results?

Immediate calming: within days. Barrier strengthening: 2 to 3 weeks. Scar softening: 8 to 12 weeks of consistent use.

How long does 50ml last?

2 to 3 months of twice-daily use. Longer if used for targeted spot treatment only.
