(aka Parsol 1789
or butyl methoxydibenzoylmethane)
Each of these ingredients protects against UVA, which has been proven to cause signs of aging and skin cancer.
On your next shopping trip for a daytime sunscreen moisturizer, if you don’t see any of those on the ingredient list as an active ingredient*, put it back. You’ll be surprised at how many moisturizers that claim to offer UV protection actually don’t have any of these ingredients. These products are simply not suitable for daytime use alone and will have to be paired with a proper sunscreen product.
Estee Lauder DayWear Plus SPF 15 for Oily Skin (featured yesterday) is a great daytime moisturizer because:
1. It has butyl methoxydibenzoylmethane as an anti-UVA ingredient.
2. It includes anti-oxidants such as grape seed extract and rosemary extract.
3. The product is housed in an opaque bottle and is dispensed with a pumper, so the anti-oxidants don’t lose their benefits due to exposure to light and air.
During daytime, UV protection is really all we need. The rest is just a plus.
In Japanese skincare and foundation products, a PA marking (ranging from PA+ to PA++++) specifies the level of UVA protection alongside the SPF marking (which only indicates UVB protection). For example, Sofina’s Very Very UV Cut Milk has the “SPF 24 , PA+++” marking.
This is standard practice in Japanese cosmetics, and I hope more western brands would adopt a similar system. This will definitely raise the awareness of proper sun protection, which is the most vital part of anti-aging skincare.

*If the list does not indicate what the active ingredients are, at least it has to be close to the top of the full ingredient list. (The ingredients are listed roughly in the order of the percentages they occupy in the formulation.)
