MeltCast: Makeup Weather Guide

Stop wondering why your makeup melted by noon. MeltCast
checks today's weather and tells you how to adjust your
routine so your look lasts all day.
Every makeup wearer knows the frustration: a flawless
morning application that breaks down by lunch. The reason?
Humidity, heat, and UV changed — and your routine didn't.
HOW IT WORKS
1. Set your skin type (oily, dry, combination, normal, or
sensitive) and the product types you use.
2. MeltCast fetches your local weather — humidity,
temperature, UV index, dew point, and wind.
3. You get a daily Melt Score (0-100) and specific
adjustments for your primer, foundation, setting,
eye makeup, blush, and SPF.
It takes 15 seconds to set up. No account required.
DAILY MELT SCORE
A single number that tells you how challenging today's
weather is for makeup. Green means go. Red means adjust
everything. Check it every morning before you start.
ROUTINE ADJUSTMENT
Based on your skin type and today's conditions, MeltCast
suggests which product types to swap, skip, or add.
Mattifying primer on humid days. Hydrating base in dry
cold. Waterproof eye products when rain is coming.

UV-based reminders for sun protection under your makeup.
Know when to reapply SPF powder throughout the day.
