[Ask Dr. Baek] Does drinking lots of water help your skin stay hydrated?

In the world of skincare, there's a sea of advice and tips. Yet, separating fact from fiction can be tricky. So, why not tackle some widespread skincare queries with the help of Dr. Baek? With over 20 years of experience in the scientific field, he's the perfect guide to navigate through these questions. Let's begin!




Q1: Does Drinking Lots of Water Keep Your Skin from Getting Dry?

A: Drinking water is essential for overall health, but it doesn't directly prevent dry skin. Dry skin occurs when there's a lack of moisture in the outer layer of your skin. While staying hydrated is beneficial, using moisturizers is key to locking in moisture and protecting the skin barrier.




Q2: The Higher the SPF, the Better?

A: Not necessarily. SPF, or Sun Protection Factor, measures how well a sunscreen will protect skin from UVB rays. SPF 30 blocks about 97% of UVB rays, and SPF 50 blocks about 98%. Beyond SPF 50, the increase in UVB protection is minimal. What's more important is applying enough sunscreen (about 1/4 teaspoon for the face, a shot glass full for the body) and reapplying every two hours or immediately after swimming or sweating.


Q3: You Don't Need Sunscreen on Cloudy Days?

A: UV rays can pass through clouds, so you still need protection even on cloudy days. Make sunscreen a part of your daily routine, no matter the weather.




Q4: Antibacterial Soap for Acne Skin?

A: Antibacterial soap is not necessarily the best choice for acne-prone skin. These soaps can be harsh and strip the skin of its natural oils, potentially worsening acne by triggering increased oil production. Instead, it's better to use a gentle cleanser formulated for acne-prone skin. Look for products containing ingredients like salicylic acid or benzoyl peroxide, which are proven to help treat acne. Apply these acne-targeted cleansers 2-3 times a week, and on the other days, stick to a mild and soothing cleanser for daily use.




Q5: Cold Water is good for Skin?

A: Lukewarm water is actually best for your skin. Hot water can strip your skin of its natural oils, leading to dryness and irritation. Cold water, on the other hand, doesn't effectively remove the day's dirt and makeup as well. Lukewarm water helps to cleanse your skin effectively without causing unnecessary stress to it.





Q6: Oil Cleanse or Foam Cleanse for Removing Makeup?

A: The best approach for removing makeup, especially if you use sunscreen (which you should daily!), is the double cleansing method. This involves two steps: first, using an oil-based cleanser, followed by a water-based cleanser.

The oil cleanser is designed to break down and remove makeup, sunscreen, and sebum effectively without stripping the skin of its natural oils. After the oil cleanse, a foam cleanser helps to remove any remaining impurities and residue, ensuring the skin is thoroughly clean and refreshed. This two-step process helps to clean the skin more effectively than using just one type of cleanser, making it an excellent routine for both improving skin health and preventing acne.



Remember, taking care of your skin doesn't have to be complicated. Stick to the basics: cleanse gently, moisturize, eat a balanced diet, and protect your skin from the sun. And don't forget to question the skincare tips you hear to see if they're really true!
