Welcome to Skin Insights by YSBB.

As the sun gets stronger, it’s time to talk about one of the most essential skincare steps: sunscreen.

Many people apply sunscreen irregularly or in insufficient amounts — reducing its effectiveness. In this guide, we’ll explain how to apply it properly and how to choose the right formula for your skin type.

☀️ Why You Should Wear Sunscreen Every Day

• UV rays reach your skin even on cloudy days or indoors through windows
• UVA rays: cause aging, pigmentation, and wrinkles
• UVB rays: lead to sunburn and dark spots
• Daily sunscreen prevents premature aging and helps lower the risk of skin cancer

✅ How to Apply Sunscreen Correctly

• Apply as the final step in your morning skincare routine
• Use about 1 to 1.2g (nickel-sized amount) for the face
• Apply 15–30 minutes before sun exposure
• Reapply every 2–3 hours, especially if sweating or outdoors

✅ How to Choose Sunscreen by Skin Type

• Sensitive Skin: Choose physical (mineral) sunscreen with zinc oxide or titanium dioxide; avoid fragrance, alcohol, and dyes
• Oily / Acne-Prone Skin: Use light, oil-free gel or emulsion types labeled "non-comedogenic" or “sebum-control”
• Dry Skin: Opt for cream-type sunscreen with moisturizing ingredients like hyaluronic acid or ceramides
• Combination Skin: Use gel on the T-zone and cream on the U-zone, or choose a balanced lotion-type product

✅ Understanding SPF and PA

• SPF (Sun Protection Factor): Measures UVB protection. Higher = stronger. Sensitive skin may benefit from lower SPF
• PA (Protection Grade of UVA): More "+" signs = better UVA protection
  • For daily use: PA++ or higher
  • For outdoor activity: PA+++ or higher

✨ YSBB Tips for Smart Sun Protection

• Apply sunscreen before makeup; after makeup, use a cushion or powder with SPF to reapply
• Don’t forget hidden spots: around the eyes, neck, and behind the ears
• After laser or peel treatments, use physical sunscreen to reduce irritation
