DIY Natural Sunscreen and After-Sun Care
Understanding Natural Sun Protection
Homemade sunscreen offers an alternative to commercial products that often contain chemical UV filters, synthetic fragrances, and preservatives. Using mineral-based ingredients like non-nano zinc oxide, you can create physical sun barriers that sit on top of the skin and reflect UV rays.
Important disclaimer: DIY sunscreen has not been tested for SPF levels and may not provide adequate protection for extended sun exposure. Consider using tested, commercial mineral sunscreens for activities involving significant sun exposure, and use homemade products for light daily use or as supplemental protection.
"Natural sunscreen: 2 tablespoons shea butter, 3 tablespoons coconut oil, 1 teaspoon aloe vera gel, 2 tablespoons zinc oxide (non-nano). Put on low heat and it will quickly liquify." — Dr. Eric Berg
Understanding Sun Protection
| Ingredient | Estimated SPF | Notes |
|---|---|---|
| Non-nano zinc oxide (20%) | SPF 15-25 | Primary sun-blocking mineral |
| Coconut oil | SPF 4-6 | Mild natural protection |
| Shea butter | SPF 3-4 | Moisturizing, some UV filtering |
| Carrot seed oil | SPF 30-40 (disputed) | Claims vary widely |
| Red raspberry seed oil | SPF 25-50 (disputed) | Claims not verified |
Note: Natural oil SPF claims are unverified and should not be relied upon for primary sun protection.
What essential oils help with sun damage?
Lavender is most recommended for burns. Helichrysum, chamomile, and peppermint (cooling) are also beneficial. Always dilute in carrier oil.
How long does after-sun care last?
Refrigerated sprays: 1-2 weeks. Balms and creams: 2-3 months in cool conditions. Discard if separation, smell changes, or mold develops.
