Background

The CD300 receptor family members are a group of molecules that modulate a variety of immune cell processes. The CD300 receptor family consists of members with activating and inhibitory capabilities mainly expressed on the surface of immune cells. LMIR5, also known as CD300b, CD300LB, CLM-7, and IREM‑3, is a glycoprotein member of the immunoglobulin superfamily. Human LMIR5 consists of a 134 amino acid (aa) extracellular domain (ECD) with one Ig-like V-type domain, a 21 amino acid (aa) transmembrane segment, and a 29 aa cytoplasmic domain. Studies have shown that CD300b recognizes PS as a ligand and regulates phagocytosis of apoptotic cells through DAP12 signaling pathway.

Really good spf
Size: 2.5 Fl Oz (Pack of 1)
I’ve been using this for a little while now and I actually really like it. It feels nice on the skin, doesn’t feel heavy, and leaves my face looking fresh and smooth. I also noticed my skin feels softer after using it consistently. Definitely something I would buy again.

Pretty lightweight
Size: 2.5 Fl Oz (Pack of 1)
Although it still leaves a little bit of a shine ( more of a dewy look), there is definitely not that much of a greasy feel which really helps me to keep being consistent with using sunscreen because my big issue with using other sunscreens is that they're too greasy feeling and not lightweight and leave too much of a shine on my already oily face.

Not for sensitive skin
Size: 2.5 Fl Oz (Pack of 1)
I have combination skin, prone to acne, and sensitive skin. Even though this is labeled as non-comedogenic and best suited for oily skin, I still experienced acne because the consistency of the sunscreen is really thick. It makes it hard to blend (really hard) and upsets my skin. It also smells a lot like alcohol, more so than most sunscreens, even those from this brand. I bet it's good for some skins but it simply wasn't for me.

Finally!
Size: 2.5 Fl Oz (Pack of 1)
I have been looking for a sunscreen that does not breaks me out or irritate my eyes and this was perfect. I wash my face in the morning and I put this sunscreen on. I don't need to use moisturizer since this is enough. It does leave my skin glowy which I like but not greasy. I notice even my dark spots are fading but because I do use this everyday. My skin is tan and it does not leave a white cast. I love it. If you have acne prone skin, oily and sensitive give this a try.
