Key Benefits of Dr. Bio Waterful Sun Stick SPF50+ PA++++

 
These are the key benefits you can expect from using Dr. Bio Waterful Sun Stick SPF50+ PA++++:
 

Very Rich Moisturizer with the Right Occlusivity for Very Dry Skin

According to CreamScan analysis, Dr. Bio Waterful Sun Stick SPF50+ PA++++ is quite moisturizing, with a moisturizing rating of 5.6 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 1.2 out of 10 and a maximum Occlusivity of 10 out of 10, primarily due to the high content of Synthetic Wax (est. ≈45.0%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of Dr. Bio Waterful Sun Stick SPF50+ PA++++ suggests a rich, thick texture, making it perfectly suited for dry skin.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Very high sun protection for prolonged sun exposure, all skin types, and high-risk conditions

With an SPF of 50, Dr. Bio Waterful Sun Stick SPF50+ PA++++ provides very high sun protection, suitable for intense sun exposure in tropical climates, beach vacations, or high-altitude environments.

This level of SPF blocks 98% or more of UVB rays, offering the highest level of defense against sunburn. Broad-spectrum formulations also provide strong protection against UVA rays, which are responsible for skin aging, pigmentation, and DNA damage.

For optimal protection, choose products labeled broad-spectrum to ensure defense against both UVA rays, which contribute to skin aging and pigmentation, and UVB rays that cause sunburn.

This level of SPF is ideal for all skin types, particularly fair, sensitive, or post-treatment skin (e.g., after laser or chemical procedures). It is also highly recommended for individuals at greater risk of skin cancer.

For extended outdoor activities or water exposure, choose a water-resistant formula and reapply every two hours for maximum effectiveness.

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Dr. Bio Waterful Sun Stick SPF50+ PA++++

 
CreamScan AI identified a few things to consider before adding Dr. Bio Waterful Sun Stick SPF50+ PA++++ to your skincare routine:
 

Best for Very Dry Skin - May Be Too Thick for Other Skin Types

With exceptional occlusivity, this product is optimal for moisturizing dry and very dry skin but may be too thick for other skin types, including normal, and especially combination and oily skin.

If you have oily, combination, or normal skin and are considering purchasing this product for the first time, it might be a good idea to try a sample before buying.

If It’s Your Only Moisturizer, It’s Better When Paired with Some Humectants

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while Dr. Bio Waterful Sun Stick SPF50+ PA++++ contains a low level of humectants.

People with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.
