Mixing LHA in Face Oil Formula / Shea Butter for Eye Area

Question

I am creating two homemade cosmetic formulas. For the face, I have acne-prone skin that gets very dry after using BHA, but I still want to use an exfoliant. I plan to make an oil-based formula with the following ingredients:

Face Oil Formula (LHA face oil):

Capryloyl Salicylic Acid (LHA) EZ™ (10%)
MSH White Absorb™ (5%)
Coenzyme Q10 Extra (1%)
Vitamin E (Tocopheryl Acetate) (0.1%)
Hemp seed OIL (rest)

I have a few questions about this formula:

If I use 10% LHA EZ™, does that mean the formula contains 2% LHA? Is this percentage sufficient for skin exfoliation?
Does adding 5% MSH White Absorb™ significantly increase the formula's irritation potential?
Can the selected ingredients all be mixed together directly in the oil?
Can this formula be used concurrently with Stabilized Vitamin C (Natural-C Glycol™) Serum?

For the eye area, I plan to make a formula with these ingredients:

Eye Area Formula:

shea butter (Refined) (98%)
Vitamin E (Tocopheryl Acetate) (1%)
Coenzyme Q10 Extra (1%)

Can this mixture be used around the eyes at these percentages?

Subject: Mixing LHA in Oil Formula for Face / Shea Butter for Eye Area

Hello,

Thank you for your questions about your homemade cosmetic formulas.

Regarding the Face Oil Formula (LHA face oil):
Ingredients:

Capryloyl Salicylic Acid (LHA) EZ™ (10%)
MSH White Absorb™ (5%)
Coenzyme Q10 Extra (1%)
Vitamin E (Tocopheryl Acetate) (0.1%)
Hemp seed OIL (rest)

Your skin concern: Acne-prone with dryness after using BHA, wanting to use an exfoliant.

Please note the staff's caution that using a large amount of oil may potentially trigger clogged pores for acne-prone skin.

Here are the answers to your questions:

LHA concentration and effectiveness: The staff confirmed that using 10% LHA EZ™ provides sufficient effectiveness for skin exfoliation.
MSH White Absorb™ and irritation: MSH White Absorb™ itself does not cause irritation. However, LHA can cause skin irritation.
Mixing in oil: Yes, the ingredients you selected can be mixed together in oil. As the staff mentioned, if you observe oil separation, you might consider adding an oil blender like Oil Blender™ (ID 1004).
Using with Stabilized Vitamin C (Natural-C Glycol™) Serum: The staff recommends applying these two products at different times (e.g., one in the morning, one in the evening). This is because Natural-C Glycol™ is acidic and combining it with LHA, which can also cause irritation, might increase the risk of skin irritation.

Regarding the Eye Area Formula:
Ingredients:

Shea butter (Refined) (98%)
Vitamin E (Tocopheryl Acetate) (1%)
Coenzyme Q10 Extra (1%)

Your question: Can this mixture be used around the eyes at these percentages?

These ingredients (Shea butter, Vitamin E, Coenzyme Q10) are generally considered suitable for use in the eye area at these concentrations. However, the skin around the eyes is delicate, and individual sensitivity can vary. It is always recommended to perform a patch test before applying any new product extensively, especially around the eye area.

We hope this information is helpful!
