3. Should I choose physical sunscreen or chemical sunscreen?
Choosing between physical and chemical sunscreen depends on many factors, including your skin type, outdoor activities, and personal preference. Here are some strengths and weaknesses of both sunscreens:
Physical sunscreen (mineral sunscreen):
- Use mineral ingredients such as zinc oxide or titanium dioxide to create a physical layer that protects the skin from the effects of UV rays by reflecting them.
- Suitable for sensitive or oily skin, as they are usually less irritating and do not penetrate deeply into the skin.
- Can be used immediately after applying to the skin, no need to wait for a period of time like chemical sunscreens.
Chemical sunscreen:
- Uses chemical compounds to absorb and convert the impact of UV rays on the skin into heat, which is then emitted from the skin.
- May be effective in protecting the skin from the effects of UV-A and UV-B rays.
- Easy to spread and absorbs quickly into the skin, suitable for makeup afterwards.
Choosing between physical and chemical sunscreen depends on personal preference and how it feels on your skin. Some people may prefer physical sunscreens because they cause less skin irritation, while others may prefer the ease of application of chemical sunscreens.
Most importantly, always use sunscreen when exposed to the sun and reapply as directed, no matter what type you use. Protecting the skin from the effects of UV rays is important to prevent skin darkening, melasma, and protect the skin from damage from the sun.
