## Description

Use active ingredients like HA, glycerin, or retinol? DewSkin checks today's dew point and UV to tell you what to use, skip, or adjust in your skincare routine.

Stop guessing whether your hyaluronic acid serum is helping or 
hurting today. DewSkin checks the local dew point — the true 
measure of moisture in the air — and tells you exactly how your 
active ingredients will behave right now.

Most people don't know that HA and glycerin pull moisture FROM 
your skin on dry days instead of hydrating it. The dew point 
changes daily, and so should your routine.

HOW IT WORKS
1. Set up your skin profile: skin type and which active ingredients 
   you use (HA, glycerin, retinol, vitamin C, AHA/BHA, niacinamide).
2. DewSkin fetches the current dew point, UV index, humidity, and 
   temperature at your location.
3. You get a personalized Skin Score and ingredient-by-ingredient 
   guidance: USE, ADJUST, or SKIP today.
It takes 15 seconds to set up. No account required.

DEW POINT INGREDIENT GUIDE
See at a glance which ingredients are safe today and which ones 
to avoid. HA and glycerin get a green, yellow, or red status 
based on the dew point. Tap any ingredient to read why.

SKIN SCORE
A daily 0–100 score combining dew point, UV index, temperature, 
and humidity into one simple number. Know instantly whether it's 
a great skin day or a day to simplify your routine.

PRIVACY FIRST
All your skincare profiles are stored locally on your device. 
No account, no tracking, no data shared. Location is used only 
to fetch weather data from a public weather service and is never 
stored on any server.

This app provides general skincare guidance based on publicly 
available weather data. It is not medical advice and does not 
replace consultation with a dermatologist.
