"For those who have reached the age of 30 or above, it is recommended to use sunscreen to prevent the appearance of black spots on their face. In the market, there are various types of sunscreen with different formulations, ranging from those aimed at brightening, moisturizing, to reducing black spots. How does sunscreen work in addressing the problem of black spots on the face? Here is the explanation quoted from id.my-best.com on (6/5)."

If the skin is experiencing pigmentation problems, it is recommended to choose a sunscreen with SPF 30 and PA+++. High protection can provide stronger and long-lasting protection against UVB rays. To protect the skin from UVA exposure, it is recommended to choose a sunscreen with PA+++ classification. If you want optimal protection, consider using a sunscreen with SPF 50 and PA++++ classification. However, sunscreen with PA+++ classification is considered to provide adequate protection against UVA rays.

Sunscreen with sun protection factor (SPF) 30 PA+++ is useful for daily activities. For individuals with sensitive or acne-prone skin, it is recommended to use sunscreen when needed, especially in the following situations: Engaging in outdoor activities or being in open environments. Living in areas with intense sunlight. When the ultraviolet (UV) index reaches a high level, especially between 10 am and 3 pm. When indoors, but still indirectly exposed to sunlight.

Physical sunscreen works by forming a layer on the surface of the skin to protect it from UVA and UVB rays. This is beneficial for dry skin as it helps to maintain its moisture. The texture of sunscreen cream is usually heavier than gel or lotion, but it is more effective in maintaining the skin's moisture. It also contains more moisturizing ingredients, so the skin becomes more hydrated and receives sufficient nourishment. The role of ceramides is very important in strengthening the skin's natural barrier to prevent moisture loss. With a strong skin barrier, dry skin can remain hydrated and moisturized.

Chemical sunscreen can be easily absorbed by the skin, leaving no oily residue and reducing the risk of clogged pores. Its function is to absorb UV rays and convert them into heat. Gel and lotion consistency are lighter compared to cream, allowing for more efficient absorption. This will reduce oil accumulation in facial pores. Humectant moisturizers work by attracting water molecules into the skin to maintain moisture. This type of moisturizer is more suitable for oily skin as it does not cause pore clogging.

For those with sensitive skin who are struggling with acne, whether in an inflamed state or not, it is important to continue using sunscreen. If the skin is experiencing problems with inflamed or sensitive acne, it is recommended to choose a physical sunscreen or a physical-chemical blend rather than a chemical one. In addition to paying attention to the type of sunscreen, also consider the presence of ingredients that have a soothing effect.
