Moisturiser for Dry Skin Calculator – How to Use and Why It Matters

The Moisturiser for Dry Skin Calculator is a tool that helps individuals determine how much moisturiser they need per day and over a set period based on their skin condition, body area, and dryness severity.

Why Use This Calculator?

People with dry skin often use moisturisers inconsistently or run out before they can restock. This calculator ensures you're:

• Applying the right amount per area
• Not underusing or wasting product
• Planning your skincare purchases accurately

Step-by-Step: How to Use the Calculator

Step 1: Select Body Area

Choose the part of the body you want to treat:

• Face – typically 2ml/day for dry skin
• Hands
• Arms
• Legs
• Full Body – up to 25ml/day for severe cases

Step 2: Choose Dryness Severity

Pick the dryness level:

• Mild – basic hydration needed
• Moderate – flaky or rough patches
• Severe – tightness, scaling, or eczema-prone

The more severe the dryness, the more moisturiser you'll need.

Step 3: Enter the Number of Days

How long do you want to calculate moisturiser usage for? Enter any duration (e.g., 30 days, 60 days).

Step 4: Click “Calculate”

You’ll see:

• Daily Moisturiser Requirement (ml/day)
• Total Moisturiser Needed for the entire period

---

Example Calculation

• Area: Arms
• Severity: Moderate
• Days: 30

Daily Usage = 6 ml × 1.5 = 9 ml/day
Total Usage = 9 ml/day × 30 days = 270 ml

You should plan to have at least 270 ml of moisturiser available for 1 month of consistent use.
