homemade物理性防曬

自從上次去完馬代船宿用過隻船homemade嘅防曬後.................影底咗佢用咩材料...............決定上iherb買材料..............google recipe................sep 14, 2019自己試整

1) 全部材料 (total hk$396.26)

-我跟上次間船宿公司所用嘅材料
-d材料可整幾個batch
-購自 : iherb
-discount rate : nil
-訂貨日期 : aug 31, 2019 (sat)
-收貨日期 : sep 2, 2019 (mon)

i) 椰子油 - 越南產地, 好多certification
- 做完第1個batch之後..............剩咗嘅攞嚟當body oil咁用

ii) raspberry seed oil

iii) non nano zinc oxide powder - 美國產地

iv) pure shea butter - 西非產地

2) 參考recipe
-份量我睇咗2個websites.................combine咗2者modify

份量
i) 椰子油 - 1/2 cup
ii) raspberry seed oil - 1 teaspoon
iii) zinc oxide powder - 4 tablespoon
iv) shea butter - 42g (事後google個conversion table...............最少都要有110g先夠1/2 cup)

3) steps
-先溝好椰子油+raspberry seed oil
-再+入shea buter間接用熱水溶佢落d油度..............好似溶朱古力片咁..............唔直接用火煮溶佢

-溶晒後................抽起離火..............戴上口罩............逐少逐少放入zinc oxide powder攪均佢
-放得耐..............zinc oxide powder會沉底..............用前要搖1陣................平均先用得

4) 用後review
-網上有評論話自家製物理性防曬嘅spf會唔穏定................我之後嘅潛水trip全程用我整嘅防曬.............嗰次陽光好猛烈...............曬落嚟皮膚喺有刺痛feel
-因為自家製防曬最好喺6個月內用完..................番到嚟香港仲有好多..............所以當day time防曬用
-到jan 2020同1年見1次嘅友仔們gathering............有2個話我嘅斑比上年嚴重咗好多😟😭............証明homemade sunscreen嘅spf唔夠高
