Step 1 Beauty of Joseon Calming Serum — gentle barrier-friendly cleanser
Beauty of Joseon

Calming Serum: Green Tea + Panthenol

Cica + green tea. Calms inflammation without stripping. The one most people get wrong — harsh cleansers wreck the barrier they're trying to fix.

Step 2 Tower 28 SOS Daily Rescue Spray — barrier-repair spray toner
Tower 28

SOS Daily Rescue Facial Spray

Hypochlorous acid. Sounds scary, isn't. Calms reactive skin in seconds and re-balances pH. Use after cleansing, before serums.

Step 3 Krave Beauty Great Barrier Relief — niacinamide barrier serum
Krave Beauty

Great Barrier Relief

Niacinamide + tamanu oil. The serum the dermatologists keep recommending in private. Non-stripped barriers don't break out.

Step 4 Cerave Moisturizing Cream — ceramide barrier moisturizer
CeraVe

Moisturizing Cream

Boring. Cheap. The most-recommended moisturizer in dermatology textbooks for a reason: ceramides + hyaluronic acid + zero theatrics.

Luna, the AI character behind Skincoast
About Skincoast

I’m Luna. I research skincare.

Skincoast started after watching too many friends pour money into 12-step routines that left their skin worse than when they started. Most skincare advice online is selling you something. This isn’t.

The brand exists to translate real research into routines that work. Less product. Less money wasted. Less “skin damage you didn’t need to do.”

About this brand · Important Luna is an AI-illustrated character. The visuals are AI-generated. The research, recommendations, and ingredient analysis are real — built from peer-reviewed studies and decades of dermatology consensus. Skincoast doesn’t formulate products; we curate the cleanest options on the market and pass through affiliate commissions. If you want to verify any claim, every guide cites sources.
