Secondary ActiveFrequently Asked Questions About Skincare Layering
What is the "thinnest to thickest" rule?
Skincare products are formulated with different molecular weights. Water-based essences and fluid serums absorb rapidly, whereas occlusive creams and oils form a protective sealant. Applying a light serum over a thick oil prevents the active from ever reaching your skin.
How long should I wait between active steps?
For pH-dependent actives like pure Vitamin C (L-Ascorbic Acid) and BHA/AHA exfoliants, waiting 1 to 2 minutes allows the formulation to interact with the stratum corneum before applying neutralizing neutral-pH creams.
Can I use Niacinamide and Retinol together?
Yes! In fact, dermatologists call them a golden combination. Niacinamide stimulates natural ceramide production in the lipid matrix, which prevents the dryness, redness, and flaking commonly triggered by retinoid usage.
What should I do if my skin stings or turns red?
Immediately rinse with cool water, stop all direct acids, exfoliants, and retinoids for 5 to 7 days, and focus exclusively on hydrating cleansers, pure hyaluronic acid, and ceramide barrier balms until full recovery.
