Hello,
Regarding the skincare formulas you provided for your daughter:

For the first formula:
The staff has reviewed it and mentioned that while it can be mixed, it might not be ideal for slightly oily skin due to the high concentration of moisturizing ingredients. They suggested the following adjustments to make it more suitable for oily skin:

Reduce Pro Vitamin B5 (ID 111) to 1%.
Reduce Double Hyaluronic Acid (ID 404) to 1%.
Remove MOIST72 (ID 257).
Consider increasing Pitera (ID 357) to 30-50% to replace some of the water.

For the second formula:
The staff noted that the water percentage calculation is incorrect and needs to be recalculated. More importantly, this formula cannot be mixed as is because Centella Asiatica Extract (ID 294) needs to be incorporated into a cream or gel base. The current formula lacks such a base. The staff recommended adding 1% Pro Polymer (ID 234) to create a gel texture, which would allow for the inclusion of Centella Asiatica Extract. The staff also mentioned they could not fully assess the suitability of this second formula for your daughter's skin without details (although you did provide skin details initially, this comment was in the context of the second formula).

Please recalculate the water percentage for the second formula and consider the staff's recommendations for both formulas based on your daughter's skin type.
