So you're interested in SPF lip products? ☀️👄Ooh! Then let us squeeze in a little biology review here🤓🤓🧪. 🔬Lip skin happens to be pretty different from its direct neighbors--the rest of your face. The lip stratum corneum is significantly thinner than other parts of skin and turns out has less water content too. It also doesn't have any sebaceous glands to produce oil that can help protect it😮🌵...and also has way less melanin (pigment) too. ✨The overall takeaway here is that the lips easily dry out, is sun-sensitive, and happens to be one of the most prominent locations exposed to the elements. Yikes! But not to fear! Embrace highly occlusive balms (this is why the best lip balms have high levels of petrolatum, beeswax, or lanolin), and consider adding in an SPF lip product to your routine to help shield your 💋💋 from the elements. . . . #ChemistConfessions #LipBiology #Skincare #Lipcare #SkincareTips #DryLips #Lips #Science #Biology
