Your Questions, Answered

What is the best way to use Spark each day?
Add it to your routine twice a day, once in the morning and once at night. Always apply it to freshly cleansed, toned skin.
Can people with sensitive skin use it?
Spark is made with soft, soothing ingredients and is meant to feel comfortable on most skin types, including sensitive ones. If your skin is very reactive or you have known allergies, test a small patch before your first full use.
How does it fit with the products I already use?
It layers easily. Apply it once your lighter essences and serums have absorbed, then follow with your moisturizer. During the day, finish with a sunscreen.
How long does it take to notice a difference?
Most people notice softer, more hydrated skin in about a week. Changes in firmness and the look of fine lines tend to appear after 2 to 4 weeks of steady use. Every skin type responds differently, so timing can vary.
Is it effective on wrinkles and sagging skin?
Spark pairs NAD with collagen to support firmness and elasticity in your skin. With regular use, this can make fine lines and loose-looking skin less noticeable over time.
