Concern Guide
Dryness
Dryness is a barrier problem — either the skin isn't holding onto water, or it isn't making enough of its own lipids to seal that water in. Humectants pull water in; barrier lipids keep it there.
H
Hyaluronic Acid
Pulls water into the skin's surface for an instant plumping effect — apply to damp skin, then seal with moisturizer.
C
Ceramide 3
A skin-identical lipid that rebuilds the barrier — the standard partner for any routine that includes an acid or retinoid.
C
Cica Extract
A calming, barrier-supporting extract — usually paired with a stronger active to offset irritation, not used to treat a concern alone.
P
Panthenol (Vitamin B5)
A hydrating, soothing vitamin B5 derivative with no known conflicts — safe to layer with anything.
S
Squalane
A skin-mimicking oil that seals in hydration — always the last step, after every water-based serum.
G
Glycerin
The most-studied humectant in skincare — cheap, stable, and the quiet workhorse behind most moisturizers.
L
Lactic Acid (AHA)
A gentler AHA than glycolic acid — a reasonable first exfoliating acid for sensitive or beginner skin.
