Background

CDKN2A, also known as cyclin-dependent kinase inhibitor 2A, is ubiquitously expressed in many tissues and cell types. The gene codes for two proteins, including the INK4 family member p16 (or p16INK4a) and p14arf. Both act as tumor suppressors by regulating the cell cycle. p16 inhibits cyclin dependent kinases 4 and 6 (CDK4 and CDK6) and thereby activates the retinoblastoma (Rb) family of proteins, which block traversal from G1 to S-phase. Somatic mutations of CDKN2A are common in the majority of human cancers, with estimates that CDKN2A is the second most commonly inactivated gene in cancer after p53. Germline mutations of CDKN2A are associated with familial melanoma, glioblastoma and pancreatic cancer. The CDKN2A gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.

It Works!
Size: 16 Ounce (Pack of 1), Style: SPF 50
My favorite sunscreen. Smells incredible. Reminds me of the beach every time I use it. Which is daily. Summers are brutal in the south and I don’t get paid enough for a farmers tan. Alba has saved me. I’m hooked on it. Also the price isn’t horrible either. Sunscreen can be so dang expensive. You get your moneys worth.

Defective item
Size: 16 Ounce (Pack of 1), Style: SPF 50
I requested a refund or replacement as one of the two bottles that arrived. Has an issue with spraying. When I put it in the unlocked position, it does not spray I requested from the seller, but the seller wants to meet to provide proof and requesting me to upload a video. When I explained the defect, they told me to move it to unlocked position. I buy this sunscreen all the time for my kids so I’m aware of how to lock and unlock a sunscreen Unfortunately through buyer/seller messaging you’re unable to leave a video so I will unfortunately have to leave a review here. I hope the seller will resolve this defective item.

Good sunscreen
This sunscreen works well, and has coconut oil base, which is good for your skin. The cans have an adequate amount in them, but I would also like to see something twice their size, if that's possible.
