【盛夏出遊】我要同陽光玩遊戲
⭐防曬功夫不能懶
⭐即使想曬黑也要預防曬傷
#星期一踢走BlueMonday
夏日防曬解密
太陽在夏天特別熱情奔放，受猛烈的陽光照射除了皮膚曬黑問題，紫外線更會加速皮膚老化，所以夏天護膚首重防曬！防曬方法有兩大類：一、塗沫防曬霜；二、穿著防曬衣物，兩類產品都有不少「密碼」，你都看得懂嗎？
關於防曬霜的「密碼」：
☀️UVA及UVB
陽光中的兩種紫外線，UVA會讓肌膚老化及曬黑，造成皺紋；UVB容易造成肌膚曬紅、曬傷。
☀️SPF
Sun Protection Factor的簡稱，是產品對抗UVB紫外線的防護指數，將曬傷時間延後，一般人在太陽下曝曬10分鐘便會曬傷，如使用SPF15防曬霜，可將曬傷時間延後15倍（SPF15 X 10分鐘 = 150分鐘）。室內活動宜用SPF15，逛街時宜用SPF30，戶外活動時宜用SPF50。
☀️PA
產品對抗UVA紫外線的能力，防止肌膚曬黑、曬老，分為PA+至PA++++四個等級，PA+有效防曬2至4小時，PA++有效防曬4至8小時，PA+++有效防曬8小時以上，PA++++有效防曬16小時以上。
防曬系數越高的產品質感越濃稠黏膩，容易阻塞毛孔，所以不要貪心，宜按場合選擇使用合適的防曬系數產品，出門前30分鐘塗抹一次，然後每2小時補擦一次就最好，濕水、出汗後宜額外補擦。
近年亦流行穿有防曬功效的衣物，你又知道衣物的防曬密碼怎解讀嗎？
☀️UPF
Ultraviolet Protection Factor的簡稱，與SPF概念一樣將曬傷時間延後，一般人在太陽下曝曬10分鐘便會曬傷，如穿著UPF15衣物，可將曬傷時間延後15倍（UPF15 X 10分鐘 = 150分鐘）。不過要注意，衣物的顏色、編織密度及衣物有否沾濕對防曬功能都有影響。
除了外在防曬，中醫理論認為「白色入肺」，適量進食白色食物有助美白肌膚，例如百合、雪耳、淮山、薏米、白朮、白芍、茯苓等，有助從內在潤肺美白。

Understanding sun protection during summer
The sun during summer is exceptionally harsh. When exposed, we do not only become darker, but the ultraviolet (UV) rays that come with it will expedite aging of our skin. This is why sun protective measures are important during summer!
There are two primary methods to protect ourselves from the sun: 1. Apply sunscreen, 2. Wear sun protective clothing. Yet, how well do we understand the science behind them?
Unveiling the science behind sunscreen:
☀️UVA and UVB
There are two different types of UV rays in the sun: UVA, which contributes to premature skin aging and causes wrinkles to develop; UVB, which is responsible for causing sunburn and suntan.
☀️SPF
The abbreviation for Sun Protection Factor; an index that measures the effectiveness of a product in blocking the UVB rays and delaying the process of getting a sunburn. An individual can get sunburnt if he or she stays under the sun for 10 minutes, but if the person uses a product with SPF 15, he or she can avoid getting sunburn for the next 150 minutes (SPF15 X 10 minutes). One should use SPF15 product for indoor activities, SPF30 for shopping trips, and SPF50 for outdoor activities in open spaces.
☀️PA
A protection score that measures a product’s ability to protect the skin from UVA, preventing sunburn and delaying the aging process of the skin. There are four ratings in this system, ranging from PA+ to PA++++. A product with the PA+ rating can last between 2 to 4 hours, PA++ 4 to 8 hours, PA+++ 8 hours and above, and PA++++ 16 hours and above.
Products that are thicker and gooier can clog the pores of our skin easily, so we have to choose the most suitable products according to our environment. Apply sunscreen 30 minutes before leaving the house, and reapply another layer once every 2 hours, especially when we break out in a sweat.
Sun protective clothing has also popular recently. How well do you understand it?
☀️UPF
An abbreviation for Ultraviolet Protection Factor. The concept is more or less the same as SPF as it works by delaying the time it takes to get sunburnt. An individual can get sunburnt if he or she stays under the sun for 10 minutes, but if the person put on the sun protective clothing with UPF15, he or she could avoid getting sunburn for the next 150 minutes (UPF15 X 10 minutes). Do note that the moisture that the garment absorbs as well as its color and density would affect its sun protection properties.
Besides adopting sun protection measures, it is important to consume ingredients that are white in color to brighten the skin. This is because Chinese Medicine believes ingredients that are white in color are good for the lungs. These ingredients include lily bulb, snow fungus, Chinese yam, coix seed, atractylodes rhizome, white peony root, and poria. In addition to moistening the lungs, these ingredients can also give us a healthier complexion.

sunscreen science 在 Daphne Charice D調 Facebook 的精選貼文
I started using retinol since nov2020. Retinoids are strong & “potent” enough to enhance collagen production, improve skin texture & pigmentation.
Some think that retinol is a miracle, some think it’ll do permanent damage to the skin. I have friends who have better skin using retinol, also have friends who have bad breakouts and haven’t recovered after 6months.
I tried reading up on retinol but the science tho... Anyway, I tried it and I’ll share MY experience :
There’s downtime using retinol. Some see it as exfoliation. Purging stage-Your skin might peel, might have serious breakouts. Skin gets extra dry (so I mix it with moisturizer) but some say that moisturizer is useless because it’s gonna be dry anyhow. Many people give up cuz it’s mentally challenging, imagine waking up to flaky skin/full face of acne for a period of time -unknown period of time.
Some friends told me to just use it everyday, take the ‘purge’ once and for all (let it 烂 max) & wait for it to recover. Some friends say I should only use once a week and that 1% retinol is too high a dosage to start with.
Retinol products are pretty expensive and I was worried that it might not work on my skin. So I went for a small 10ml Drunk Elephant A-Passioni. My first choice was Sunday Riley’s A+.
First week :breakout with 2-3pimples here & there
Second week :skin peeled badly -whole face
Third week :skin peeled -forehead
I consider myself lucky, it isn’t that bad for me. I saw result in just weeks but it took months for my skin to only have minor peel once in a while under my eyes (nothing serious). It’s a nuisance cuz it doesn’t give you a warning when it’s gonna peel. It doesn’t peel the next day after using, sometimes it peels few days after using. The most noticeable effect/result is that my skin glows 皮肤很亮很亮 and my skin tone is more even now (with the help of many other skincare products too).
Will I recommend retinol? I personally love it, I took the risk. However, I won’t recommend it cuz it’s too risky. DO NOT go under the sun with retinol on your face, it can burn your skin. They say use a sunscreen on top but to avoid any accident, I only use retinol at night.

有時用天然礦物色粉，有無諗過點解隻粉可以有閃粉又有顏色，但自己又好似整唔到咁？
ZaZa老師話你知！首先一齊了解天然礦物色粉嘅成分先，包括有雲母粉、二氧化鈦，同埋氧化鐵，雲母粉顏色偏透明，所以需要加工一層二氧化鈦，令雲母粉經光線折射下變得唔透明，之後再加氧化鐵就可以整到唔同顏色㗎喇！不過，我哋係自製唔到天然礦物色粉㗎，哩點大家要留意喇！
各種顏色的天然礦物色粉
