We all know that different sunscreens have different SPFs. 30x and 50x are two common types, and the sun protection strength of 30x and 50x is different. So, which is better, 50x sunscreen or 30x sunscreen?

Which is better, 50x sunscreen or 30x sunscreen?

It is difficult to say which one is better. The key is to use which one according to the specific situation and choose different sunscreen products for different occasions. 30x and 50x are two common sunscreen indexes, and the sun protection strength of 30x and 50x is different. Generally, high-factor 50x sunscreen is generally used outdoors in summer, such as hiking, swimming at the beach, shopping, etc.; while low-factor sunscreen is suitable for scenes where the sunlight is not so strong and is suitable for daily use. Most people use 15x and 30x sunscreen.

The difference between 30 times and 50 times sun protection

1. Sun protection factor. We all know that the sun has ultraviolet rays, and the wavelengths of ultraviolet rays are divided into long and short. The long waves are more likely to make us darker, and they usually appear in the morning and evening. This is the time period for sunbathing. The short waves will sunburn our skin, and they usually appear during the hot noon period. It is recommended not to go out at this time. In daily life, when the sunlight is not so strong, it is completely fine to use 30x or 15x sunscreen. If the sun is stronger, you need to be careful. In addition to using 50x sunscreen, you must also avoid direct sunlight. The reflection of strong sunlight on the ground will make you darker.

2. Usage scenarios. High-factor sunscreen is generally used outdoors, such as hiking, swimming at the beach, shopping, etc.; low-factor sunscreen is suitable for scenes where the sunlight is not so strong and is suitable for daily use. Most people use 15x and 30x sunscreen.

3. Ingredients. A low SPF means that the content of the ingredients used is less, the product is lighter, and it feels more refreshing to use. Products with a high sun protection index contain more ingredients, and the paste is thick, which increases the burden on the skin and makes it more difficult for the pores to breathe.

4. Durability of sun protection. The difference is easy to understand. A high SPF is more durable, while a low SPF is not as durable. The duration of sun protection is directly related to the index.

How to choose the right sunscreen for you

1. Oily skin. People with this skin type should choose a water-based, oil-free sunscreen with strong penetration, which feels refreshing and non-greasy and does not clog pores. Never use sunscreen and use physical sunscreen products with caution.

2. Dry skin. People with this skin type can choose sunscreens that are moisturizing, hydrating, and able to enhance skin immunity. Many sunscreens now have added hydrating and antioxidant effects in addition to sun protection.

3. Sensitive skin. Sunscreen products from skin care brands that are specialized for sensitive skin, or products that clearly state "allergy tested", "clinically tested on young children by dermatologists", "free of fragrances and preservatives" etc., are best to choose physical sunscreens, mainly because chemical sunscreens are irritating and can cause varying degrees of damage to the skin!
