Formulating Night Facial Oil for Anti-aging & Whitening

Based on your goal for a night facial oil for normal to dry skin with wrinkles, melasma, and freckles, and your proposed base of Argan Oil and Rose Hip Oil, here's a breakdown and suggestion:

1. Third ingredient for whitening: Natural oils like Argan and Rosehip are excellent for moisturizing and anti-aging (helping with wrinkles), but they do not directly lighten melasma or freckles. To address these concerns, you need to add specific whitening agents.

   • Activated Resorcinol (Product ID 493) is a good option that dissolves easily in oil. You can typically add it at 0.1-1% concentration.
   • MSH White (Product ID 699) is another effective whitening agent. As discussed in the thread, it may require a solvent like Ethoxydiglycol (Product ID 137) to ensure it dissolves properly in the oil blend. A common approach is to dissolve MSH White (e.g., 1%) in Ethoxydiglycol (e.g., 5%) first, and then add this mixture to your oils.

2. Is 20% Rosehip Oil too heavy? The perception of oil weight is subjective and varies by individual. As mentioned by the staff, many people find Rosehip Oil (Product ID 88) to be relatively light. The percentage you use depends on the texture you prefer for your skin.

3. Should a lighter oil like Jojoba Oil be used? According to the staff, Jojoba Oil (Product ID 87) is often considered heavier than Rosehip Oil. If you find your final blend too heavy, you could consider adjusting the percentages of Argan and Rosehip or exploring other oils, but based on the staff's comment, Jojoba might not provide a lighter feel compared to Rosehip.

Suggested Formula Incorporating Whitening:

Based on the discussion, a formula combining your base oils with a whitening agent and a suitable solvent (if needed) would be effective. Here is an example using MSH White and Ethoxydiglycol:

• Argan Oil (Product ID 89): 60%
• Rose Hip Oil (Product ID 88): 34%
• MSH White (Product ID 699): 1%

• Ethoxydiglycol (Product ID 137): 5%

• Instructions:* Dissolve MSH White in Ethoxydiglycol first, then mix with the Argan and Rose Hip oils.

Alternatively, if you prefer a simpler formula without a solvent, you could use Activated Resorcinol:

• Argan Oil (Product ID 89): 60%
• Rose Hip Oil (Product ID 88): ~39%

• Activated Resorcinol (Product ID 493): 1%

• Instructions:* Add Activated Resorcinol directly to the oil blend and stir until dissolved.

Choose the formula that best suits your preference for ingredients and ease of preparation. Adjust the percentages of Argan and Rosehip within the oil portion to get your desired texture.
