Shower Gel Formulation for Acne and Scar Treatment: Ingredient Suitability and Mixing
Question
I am developing a shower gel formula and have the following questions regarding its properties and ingredients:
- Is this formula suitable for both face and body, considering different skin types?
- Will this formula be effective in reducing acne and acne scars?
- Will using this formula result in dryness or irritation after washing?
- Can the ingredients in the formula be mixed manually, as I do not have a mixer?
Additionally, I would like to know about the suitability of the following ingredients in a rinse-off shower gel formula:
- Zinc PCA
- Licorice Extract (Licochalcone A 1%)
- Natural Betaine (Trimethylglycine)
- Encapsulated Salicylic Acid (Liquid, Timed-Release)
- WaterLock™

Subject: Review of Shower Gel Formula
Hello,
Thank you for sharing your shower gel formula and requirements. Based on the feedback provided by the staff:
Regarding your goals:
- Suitable for Face and Body, Skin Type: The formula uses a Sulfate Free Shampoo Base, which is a gentle cleansing agent. The staff mentions that dryness after washing depends on the concentration of the cleansing base, and you may need to adjust the percentage of the Sulfate Free Shampoo Base (Item 1) to suit your skin's needs. Irritation is individual, so it's not possible to guarantee no reaction.
- Reduce Acne and Acne Scars: The formula includes Encapsulated Salicylic Acid (Item 2), which the staff confirms can help reduce clogged pores (acne). However, the staff notes that this formula will not help reduce acne scars. Treating acne scars typically requires leave-on products containing ingredients like whitening agents or exfoliants. For acne pits, ingredients that stimulate collagen, such as Vitamin C or Copper Peptide, are recommended in leave-on applications.
- No Dryness or Irritation: As mentioned above, dryness can be managed by adjusting the concentration of the cleansing base. Irritation is individual.
- Manual Mixing: Yes, the staff confirms that the ingredients can be mixed manually. Stir gently to avoid creating excessive foam.
Regarding the ingredients in your formula, the staff advises that some ingredients are less effective in a rinse-off product because they do not remain on the skin long enough to provide benefits. These include:
- Zinc PCA (Item 3)
- Licorice Extract (Item 4)
- Natural Betaine (Item 6)
The staff notes that Encapsulated Salicylic Acid (Item 2) and WaterLock™ (Item 5) have cationic properties, allowing them to adhere to the skin even after rinsing, making them more suitable for a rinse-off product compared to the others listed above.
In summary, your formula is suitable for manual mixing and contains an ingredient (Encapsulated Salicylic Acid) that can help with clogged pores. However, some ingredients may not be effective in this rinse-off format, and the formula is not expected to treat acne scars. You can adjust the cleansing base percentage to manage dryness.
