What's the best way to layer this cream with other skincare products, like serums or sunscreens?

For effective layering, apply products from thinnest to thickest consistency. Start with any water‑based serums or treatments (e.g., containing vitamin C or hyaluronic acid) on clean, damp skin. Allow them to absorb fully—about 1–2 minutes—before following with this collagen cream. Its glycerin will help draw in the moisture from the serum, while the emollients seal it in.

Because the cream contains dimethicone, which creates a silky barrier, it should be applied before any oil‑based products or heavy occlusives. For daytime, always finish with a broad‑spectrum sunscreen; the cream's lightweight texture shouldn't pill under most sunscreens if you wait a minute for it to settle. At night, you can use it as your final moisturizing step. Note that retinyl esters in the formula are included for skin‑conditioning; they are not a substitute for a dedicated retinol treatment serum.
