Science in skincare is so unpredictable and, often for me, so low-brow. Not always in a "this is too wacky for me to like" kind of way; more in a "that's different" kind of way. I have this reaction with Guinot Large Ecran SPF 30 Sunscreen.

The French line Guinot is known for being innovative in the skincare industry and pioneering some interesting products. Guinot's Large Ecran SPF 30 Sunscreen was quite striking when I learned DNA was added into the product. After some research, I discovered this was a fairly new method (within the past ten years). DNA added to the sunscreen is beneficial.

In a nutshell (because it gets rather technical and complex), the ultraviolet light from the sun causes damage to the skin cells by actually changing the structure of the DNA in them. Introducing small bits of DNA (thymidine dinucleotide) can boost the cell's repair pathways so they remove more of the damaged bits of DNA after UV exposure.

The DNA is essentially major protection from the sun and Guinot's touted, patented Nucleic Defense complex (DNA, heliotropine, filtres and UVA-UVB screens) is basically the abstinence to the regular sunscreen's condom. The complex combines UVA and UVB filters with actual DNA molecules so it reflects as much as it repairs and protects. When applied, it actually absorbed pretty fast and didn't have that "sunscreen smell." It was actually quite fragrant.

The great thing is that it's not all science. The Large Ecran Sunscreen contains horse chestnut and Enteine extracts, which help soothe, as well as Vitamin E to neutralize free radicals.
