Comparing Fractionated Coconut Oil vs. Grape Seed Oil and Oil Base vs. Cream Base for Whitening Actives

Regarding your first question about which oil is lighter and absorbs better between Fractionated Coconut Oil and Grape Seed Oil, Fractionated Coconut Oil is generally considered lighter and absorbs more quickly into the skin. It also has the advantage of being much more stable and less prone to rancidity compared to Grape Seed Oil.

For your second question about using an oil base for oil-soluble whitening agents and whether it will be as effective as a cream base, oil-based formulations (like anhydrous oils) are often very effective at delivering oil-soluble active ingredients into the skin. The oil base is compatible with the skin's lipid barrier, which can facilitate the penetration of oil-soluble substances. While direct comparisons can vary depending on specific formulations, an oil base is theoretically and practically well-suited for delivering oil-soluble actives effectively.
