Nice starter skin care set that refined pores for a smoother and brighter complexion
This cleansing oil was purchased and arrived as a 3pc set that I have purchased. Along with this cleansing oil, it also came with the toner and closer pore reducing serum. I have been incorporating all three products into my daily skin care routine/regimen. So cleanse, tone, then moisturized. This cleanser is very gentle, and it leaves my skin feeling clean and refreshed after cleansing, to prepped it before I apply the toner and follow up with the Closer pore reducing serum as the last step. Overall, I really like this set. The Close serum has a thicker consistency than my other serum, but it applies well and also seem to absorbed fairly quickly, so it doesn't leave my skin/face feeling sticky.

Gentle, Effective & Perfect for Travel!
I’m extremely happy with this Bikini Trimmer for Women! The dual ceramic blades provide a close, smooth trim without pulling, irritation, or discomfort. It’s gentle enough for sensitive areas while still being powerful enough to handle thicker hair. The compact design is lightweight and easy to hold, making grooming quick and stress-free. I also love that it can be used on multiple areas, including the bikini line, face, underarms, and body, making it a versatile addition to my self-care routine. The 90-minute cordless runtime is impressive, and the rechargeable battery lasts through multiple uses before needing a charge. Being waterproof is another huge plus—it’s convenient to use in the shower and easy to clean afterward.
