rdrd RED APPLE LACTO CALMING SERUM

Most redness serums just sit on the surface. This one goes deeper — carrying Vitamin B5 into the skin to calm irritation at the source.

rdrd RED APPLE LACTO CALMING SERUM is a calming K-beauty treatment serum for sensitive, irritation-prone skin. Panthenol (Vitamin B5) and Apple Lacto Exosome™ — plant-derived exosomes from lacto-fermented apple acting as nano-delivery vehicles — work as a synergistic duo that soothes irritated skin at every layer.

Size: 1.01 fl oz / 30 ml

  • Redness and heat from irritation visibly soothed

Key Ingredients

Panthenol (Vitamin B5) — 0.5% · draws in and holds moisture, supports ceramide and lipid synthesis for the skin barrier, reduces transepidermal water loss, and helps calm visible irritation.

Apple Lacto Exosome™ — 5% · plant-derived exosomes from lacto-fermented apple; a nano-delivery vehicle that carries Panthenol deeper into the skin layers while supporting renewal and antioxidant defense.

How to use

1. Cleanse, then apply your rdrd RED Popping Toner.
2. Dispense 2–3 drops and press gently into skin — don't rub.
3. Follow with moisturizer. Use morning and night.
4. Always layer SPF over it in the morning.

Who it's for

Sensitive skin, irritation-induced redness, and a damaged or weakened skin barrier. The treatment step of your redness routine — apply after toner.

FAQ

Can I use this with actives like retinol or acids?
Yes. Panthenol is gentle and layers well. If your skin is reactive, introduce strong actives gradually.

Is it safe for rosacea-prone skin?
Yes — it's formulated for sensitive and reactive skin. If you're highly reactive, patch test first.

How long until I see results?
Irritation and heat often feel calmer right away; barrier strength and lasting redness reduction build with consistent daily use.
