Have you noticed that sunblock and sunscreen have a different meaning? A sunblock’s primary job is to protect you from the UVB rays(B for Burning), and sunscreen protects you from UVA rays, where the ‘A’ stands for aging. So, while sunblock works physically, sunscreen works chemically preventing and repairing any long-term damage to the skin. These days formulas often contain a mixture of both sunblock and sunscreen to protect skin.
This is new to me(^^;;) and I’m guessing most Koreans also think any of the sun products will do the same job, whether named sun block, sun cream, sun fluid, sunscreen etc,. (most Korean sun products labelled as a ‘sun cream’) – I will use ‘sunscreen’ for the Korean UV protection products in this post.
*What is sunscreen and what does SPF stand for?
Sunscreens work by absorbing or reflecting the sun’s ultraviolet(UV) light, thereby reducing the amount that reaches the skin. Diligent use of sunscreen can also slow or temporarily prevent the development of wrinkles, moles and sagging skin.
The sun protection factor (SPF) of a sunscreen tells you how long you can stay in the sun without burning.
Hmm.. so if I’m using SPF50 can stay upto 10hrs, right?^^;; – I’m not good at numbers, however one thing I surely recommend that use a broad spectrum SPF of 30 or higher one every single day. It protects not only against sunburn, but reduce the risk of skin cancer and premature skin aging caused by the sun.
*What are the types of sunscreens available?
Depending on the mode of action, sunscreens can be classified into 2 main types of sunscreen: physical sunscreens (that reflect the sunlight) or chemical sunscreens (that absorb the UV light).
*Why is important using a sunscreen?
1. Sun damage accelerates the signs of aging (ex. premature wrinkles)
2. Damages our skin on a cellular level – the skin is weakened and difficult to repair damage, and bruises easily
3. Facial brown spots and skin discolorations
4. Cause skin cancer
Our favorite movie star ‘Hugh Jackman’ also warned on his instagram how sunscreen is important when he got rid of his basal cell carcinoma from his nose. Another picture shows a truck driver after being exposed to the sun for 25 years – his left side of face has damaged from UVA.
*So what are those good-to-go sun screens?
Before revealing good products, I’d like to mention ‘dangerous ingredients’ which Get It Beauty selected and mostly used for chemical sunscreens.
Just Reminder ‘9 harmful Ingredients’ which chosen by Get It Beauty pledge ‘Reduce Body Burden’.
• Sodium Lauryl Sulfate/ Sodium Laureth Sulfate
• Oxybenzone (Benzophenone-3)
• Isopropyl Alcohol
• Synthetic Fragrance
• Synthetic Colouring
It should labelled on the sun product as a ‘Butyl Methoxydibenzoylmethane‘.
Avobenzone, which is the most common UVA chemical filter and is very unstable and degrades in sunlight, however, it can be stabilized when formulated in conjunction with other UV filters.
Likewise it should be labelled as a Benzophenone-3.
Oxybenzone is linked to hormone disruption and potentially to cell damage that may lead to skin cancer, however Oxybenzone is one of the few FDA-approved ingredients that provides effective broad spectrum protection from UV radiation.
Also Korean law allows up to 5% of content so you may see some of the popular Korean & international brands sunscreens.

Q1. If I use higher SPF and low SPF at the same time what would be a protection?
A: The last(top layer) products’ SPF is the final number as it soaked into skin.
Q2. It’s hard to reapply a sunscreen over the makeup, any tips for it ?
A: Wrap a facial tissue on the makeup puff and gently dap to absorb excess sebum or oils, then apply a sunscreen. You can have refreshed, protected skin again.^^
I know it’s really hard to find the best sunscreen which works for you – skin condition, weather, ingredients, combination with base makeup products etc,. there are many factors to consider, especially under makeup (somedays good somedays not – it may ‘time’ issue how long you spend to get absorbed or ingredients/filter is the key)
Hopefully this information is helpful and see you next blog with more about Korean popular sunscreens.
Make sure you’re wearing some form of SPF everyday. Thanks for reading~
