Do I need to remove sunscreen? What will happen if I don't remove sunscreen?

Every time I apply sunscreen, I wash my face directly without removing makeup. But my friend told me that sunscreen should not be left on the face as it is bad for the skin. Do I need to remove makeup after applying sunscreen? What is the best way to remove sunscreen if necessary?

Do I need to remove sunscreen?

Sunscreen requires makeup removal. Sunscreen, an ingredient in sunscreen, is the most difficult to wash off with water and facial cleanser, and can cause damage to the skin over time. Physical sunscreens generally use oily solvents, which are thicker and heavier. When applied to the facial skin, they turn white. They are more granular and difficult to wash off. Chemical sunscreens have a refreshing texture and do not turn white or be greasy. If you do not remove makeup, they can easily penetrate into the skin and cause allergies and other problems. Whether you apply sunscreen or sunscreen spray, you need to remove your makeup.

What should I use to remove sunscreen?

After applying sunscreen, you must use makeup remover to remove makeup first.

Nowadays, many sunscreens are waterproof and oil-proof, so they need to be removed carefully with makeup remover. Because waterproof sunscreen is insoluble in water, general cleaning products cannot remove oil-soluble dirt, and the residue will clog pores and cause acne and blackheads.

Therefore, you must use special makeup remover products. You can choose the appropriate makeup remover product according to your personal skin condition and needs.

What happens if you don't remove sunscreen?

1. Incomplete cleaning will cause dirt and other impurities on the skin to accumulate, creating an environment for bacteria that can easily infect the skin.

2. Sunscreen and facial dirt will clog the pores of the skin, which will become larger, causing blackheads to appear, and the skin condition will become worse and worse.

3. The skin's resistance becomes weaker, and once it encounters external stimuli, various skin problems will arise.

Can I go to bed without washing off the sunscreen?

General sunscreens can be divided into two categories according to the sunscreen agents: physical sunscreen and chemical sunscreen. The working principle of physical sunscreen is to rely on reflection to block ultraviolet rays and achieve the purpose of sun protection. This is like putting on a protective clothing for the skin. When the sunlight hits the protective clothing, it is radiated away, and the skin will not come into contact with ultraviolet rays. Physical sunscreens "lie" on the surface of the skin. Since this type of sunscreen must be stably blended with other ingredients to form a sunscreen, oily solvents are generally used. Therefore, physical sunscreens are relatively thick. When applied to the face, the skin will turn white and the skin will be more granular.

Chemical sunscreens absorb ultraviolet rays in sunlight and convert them into heat energy, thereby preventing ultraviolet rays from damaging the skin. The advantages of this type of sunscreen are that it has a refreshing texture, does not cast a white cast, and is non-greasy, making it suitable for all skin types. However, it takes time to be absorbed by the skin and is "not long-lasting". This is why some people say no when talking about whether you need to remove makeup after using sunscreen.

Physical sunscreens are absorbed on the surface of the skin and mixed with other skin care products. Simply washing your face cannot clean them. This will affect the skin's absorption of nutrients from skin care products and will also hinder the patency of pores. Moreover, there are many sunscreens that are waterproof and difficult to clean, so sunscreens with physical sunscreens need to be removed.

Although chemical sunscreens will be converted as they absorb ultraviolet rays, not all applied sunscreens will be converted. Moreover, if chemical sunscreens are not removed, they can easily penetrate into the skin and cause allergies and other problems.
