Estée Lauder Perfectionist Youth Infusing Serum Makeup is an oil-free foundation that provides medium-to-full coverage and is said to brighten, hydrate, and reduce the look of fine, dry lines. It is available in 15 different shades so that you can choose the one that best matches your skin tone. The active sunscreen ingredients in this foundation are octinoxate (7.50%) and titanium dioxide (1.90%). Octinoxate is a synthetic chemical sunscreen ingredient, which means it protects the skin by first absorbing UV light, then transforming that light energy into some other form of energy, such as heat. In contrast, titanium dioxide is a mineral sunscreen that works by blocking or deflecting UV light, rather than being absorbed by the skin. The combination of these ingredients provides broad spectrum protection, which means the skin is protected from both UVA and UVB rays.
Estée Lauder Perfectionist Youth Infusing Serum Makeup also contains several different types of anti-aging ingredients. For example, this foundation includes acetyl hexapeptide-8, also known as argireline. Acetyl hexapeptide-8 is a six amino acid peptide and is a fragment of SNAP-25 (a substrate of botulinum toxin). It works by limiting the ability of neurotransmitters to activate movement in your facial muscles, for example, when forming facial expressions such as smiling or frowning. By inhibiting the nerves that cause facial muscles to contract, subtle facial expressions are limited and wrinkles are subsequently reduced. This foundation also includes caffeine, a natural stimulant and antioxidant that can help to firm the skin and may help to reduce the appearance of dark circles underneath the eyes.There are also many hydrating ingredients in the Estée Lauder Perfectionist Youth Infusing Serum Makeup, such as chlorella extract, artemia extract, glycerin, sodium hyaluronate, and more.
