## Description

Organic Complex Peptide Face Serum by CosDeBAHA, Matrixyl3000 Argireline with Hyaluronic, Anti Aging & Anti Wrinkle face moisturizer for signs of aging wrinkles, Organic Ingredients, Praben Free, 1oz

Review: It took me a while to like this serum because it is so sticky, and paired with other moderately sticky serums (like L’Oreal’s retinol serum), my face is even stickier. But since I use this only at night, I can overlook the stickiness and somewhat heavy feel after I top off with my night moisturizer. I love how soft my face is in the morning after I wash it with a gentle cleanser. I have aging skin that is slowly filling with spots and hyperpigmentation. This serum has helped a lot over the last four weeks, along with an arsenal of other actives, like Vitamin C, retinol, retinal, collagen, and peptides, put together in separate morning and evening skincare regimens. I’ve used other Cos de Baha products and like them all, this Niacinamide 20% being one of the main actives in my arsenal. No weird smell or funny texture, just a clean product that works. As far as this being a pore reducer, I cannot speak for that because I’ve had huge pores since birth and even lasers and microneedling at my dermatologist’s office haven’t shrunk them — my gift in the crapshoot that is genetics. My main problem now is the discoloration on my face that came after menopause, and this serum is definitely helping.
Review: Falta ver en cuanto tiempo hace efecto visible, tiene buena pinta en general

## Questions & Answers

**Q: In what country is this made?**
A: The back of the bottle has a label that says Made In S. Korea.

**Q: How does it help skin?**
A: Brightens the overall look of your skin.

**Q: Sirve para piel grasosa?**
A: Si, de hecho yo tengo piel grasa y me trabaja muy bien

**Q: Can you use this in a micro needle vial, or is it too powerful?**
A: Per directions, apply this product to chin or neck to do a patch test to make sure you have no allergic or harsh effects. If not, I'm sure you can use this serum with the micro-needling. Anytime you perform the micro-needling it's very beneficial to have a serum to protect the skin from needle entry and of course to let your favorite serum penetrate the skin.
