Questions
Skincare questions answered with citations to the studies behind every claim.
Does slugging help wrinkles or just dry skin?Slugging is mostly an overnight hydration trick rather than a wrinkle treatment.
How do I choose a moisturizer for acne-prone aging skin?Acne-prone aging skin usually does best with a moisturizer that is built around humectants and a calm barrier rather than around heavy occlusives.
What causes dry patches that won't go away?Dry patches that stick around for weeks are usually a stack of small things rather than one product.
Why do my dark spots come back after fading?Dark spots that fade and then return are usually telling a story about ongoing pigment-driving inputs rather than a failed routine.
What helps neck lines without procedures?Neck lines respond best to a small routine the skin can keep up with, not to one heroic product.
How do I choose a retinoid for aging skin?Choosing a retinoid for aging skin is less about hunting for the strongest formula and more about matching strength, vehicle, and frequency to the skin that has to wear it.
Is growth factor skincare worth it?Growth factor skincare can be worth it as a comfortable, antioxidant-style anti-aging step for fine lines, hydration, and a more rested-looking finish, but only inside a routine that already includes daily sunscreen and, for most readers, a retinoid.
How do I repair over-exfoliated skin?The repair almost always starts by doing less, not by buying another product.
