A booster is neither a serum nor a cream: you apply it in between, or mix it into your skincare. This one sits at 0.1% retinal in liposome form, which carries the active deeper into the skin.

The formula also holds 3% Matrixyl 3000, a peptide complex that works on firmness, and 1% panthenol that hydrates and calms. The texture is light, so it combines easily. One bottle holds 15 ml.
