Essential Skincare Questions: Cleansing, Moisturizing, and Sunscreen Tips

Consultation Inquiry

Hello Dr.
Cheng,
I have several questions to ask you (I’m really sorry for taking up your time).

1.
When washing my face, is it okay to use cold water directly, or is it better to use warm water?
2.
Are sunscreen lotions available in stores or counters considered cosmetics? After applying them to my face, do I need to use a makeup remover, or can I just wash my face with soap (I don’t wear makeup)?
3.
After washing my face, do I have to apply toner, or can I go straight to applying a moisturizer? If my skin is too dry in winter, is it better to apply a moisturizer directly or to use toner followed by lotion?
4.
Do most toners available in stores or counters contain ethanol? Can it cause significant harm to the skin?
5.
Is it true that gel-based cleansers are more likely to retain moisture on the face?
Thank you for your patient answers! ~~~^_^~~~ Thank you!!!

Hello! 1.
It is better to wash your face with lukewarm water.
2.
According to the Cosmetics Hygiene Management Act, "cosmetics refer to products applied externally to the human body to moisturize the skin, stimulate the sense of smell, mask body odor, or enhance appearance." Therefore, sunscreen lotion is also considered a cosmetic.
If the sunscreen has waterproof and sweat-resistant properties, it is best to remove it with a makeup remover before cleansing with soap or facial cleanser.
3.
After washing your face, it is not necessary to apply toner; you can directly apply a moisturizer.
This applies in winter as well.
4.
Not all toners available in the market or at specialty counters necessarily contain ethanol.
Even if they do, it does not always harm the skin; it depends on the concentration and skin type.
5.
No.
Best wishes for health from Dr.

Hello! Thank you for your thoughtful questions regarding essential skincare practices. Let’s address each of your inquiries in detail.

1. Cleansing with Cold vs. Warm Water: It is generally recommended to wash your face with lukewarm water rather than cold water. Warm water helps to open up the pores, allowing for a more effective cleansing process. It can help dissolve dirt, oil, and makeup more efficiently than cold water. Cold water, while refreshing, may not cleanse as deeply and can sometimes leave residues behind. After cleansing, it’s advisable to rinse with cool water to help close the pores.

2. Sunscreen as a Cosmetic Product: Sunscreen is indeed classified as a cosmetic product, as it is applied to the skin to protect against UV radiation. If you are using a sunscreen that is water-resistant or sweat-resistant, it is best to use a makeup remover or a cleansing oil to ensure that it is fully removed from your skin. Following that, you can use your regular facial cleanser to wash your face. Even if you do not wear makeup, thorough cleansing is important to remove all traces of sunscreen, as it can clog pores if left on the skin.

3. Toner vs. Moisturizer: After cleansing, applying a toner is not strictly necessary; you can go directly to your moisturizer. However, toners can help to balance the skin's pH and provide an extra layer of hydration. In winter, when skin tends to be drier, it is often beneficial to apply a hydrating toner first, followed by a moisturizer. This layering can help lock in moisture more effectively, especially in dry conditions.

4. Alcohol in Toners: Not all toners contain alcohol, but many do. Alcohol can be drying and irritating for some skin types, particularly sensitive or dry skin. It’s important to read the ingredient list and choose alcohol-free toners if you have concerns about dryness or irritation. The impact of alcohol on the skin can vary based on the concentration and your skin type, so it’s essential to choose products that suit your individual needs.

5. Gel Cleansers and Moisture Retention: Gel cleansers are often formulated to be lightweight and may not leave as much moisture on the skin compared to cream or lotion cleansers. However, whether they retain moisture depends on the specific formulation. Some gel cleansers are designed to hydrate while cleansing, but if you find that your skin feels tight or dry after using a gel cleanser, you might want to consider switching to a creamier formula that is more hydrating.

In summary, a proper skincare routine involves using lukewarm water for cleansing, ensuring thorough removal of sunscreen, and considering the use of toners based on your skin's needs. Always choose products that align with your skin type and concerns, and remember that hydration is key, especially in dry seasons. Regularly assessing your skin's response to products will help you maintain a healthy and balanced complexion. Thank you for your questions, and I hope this information helps you in your skincare journey!
