Frequently asked questions

Have a question? Here are the answers our customers ask most,

Asterwood uses Magnesium Ascorbyl Phosphate (MAP), which is the most stable and water-soluble form of Vitamin C. Unlike L-Ascorbic Acid serums that can oxidize and turn orange, MAP maintains its potency over time without degrading. Store away from direct sunlight for best results. This form absorbs instantly into skin to hydrate and firm while it brightens.
Yes. The old myth that Vitamin C and Niacinamide cancel each other out has been debunked by research. They complement each other well — Vitamin C combats free radicals and brightens, while Niacinamide refines pores and controls oil. Use Asterwood's Vitamin C during the day for antioxidant protection, and the Niacinamide Serum at night for texture refinement, or layer them in the same routine.
Asterwood recommends using this serum during the day. Vitamin C is a potent antioxidant that protects skin from UV damage and environmental pollution, so you get the most benefit from morning application. Apply to clean, dry skin, follow with moisturizer and sun protection. For your evening routine, consider pairing with Asterwood's Copper Peptides for overnight repair.
It's best to use them at different times. Vitamin C works best as a daytime antioxidant (morning), while Copper Peptides are ideal for overnight repair (evening). Using them in the same routine can reduce the effectiveness of each. An AM/PM split gives you the full benefit of both — brightening and protection during the day, firming and collagen support at night.
