And what is the PDD? As they explain to CuídatePlus from La Roche-Posay, ” like UVB rays, there are different levels of protection against UVA rays , known as PPD ( Persistent Pigment Darkening or Persistent Pigmentary Darkening)”.
” Sunscreen with a high PPD provides better protection from the damage caused by UVA rays responsible for intolerances to the sun, premature aging of the skin, the appearance of spots or simple pimples and that can cause an increased risk of cancer of skin”.
As they point out, a sunscreen with a good SPF / PPD ratio ” offers the best protection against UV rays .”
Retinol, redness and other doubts
During his speech, Borregón also mentioned the beauty treatments most demanded by Spanish women in consultations. Thus he indicated that the star molecules are retinol , “to be used during the night as a skin regenerator; Vitamin C, to be applied during the day, being a powerful antioxidant , and hyaluronic acid, which can be used daily for its ability to hydrate and capture water . ”
Regarding the use of retinol for the most sensitive skin, Borregón explained that “many patients do not use it for fear of an irritating skin reaction.”
According to her, retinol ” is advisable for sensitive skin as long as it is combined with the indicated assets .” For example, “the complementary use of vitamin B3 is important because it compensates for the skin irritation caused by retinol”, and has very good results.
Also, according to her, well-recommended retinol ” is a good treatment for sensitive skin .” Thus, she encouraged women with sensitive skin to ask their dermatologist about the benefits of this asset and its application.
On the other hand, what happens to skin with redness? Is it the same redness as rosacea? This was another of the doubts that the dermatologist cleared during the meeting, and that is that “many times both disorders get into the same bag when they are not.”
The Rosacea is more than redness, ” goes beyond the appearance of small veins on the cheeks and requires a more specific and patterned by a dermatologist treatment , ” he said.
