Serum Formulation for Combination/Acne-Prone Skin: Ingredient Compatibility, Mixing, and Texture

Question

I have formulated a serum for my combination and acne-prone skin, targeting dark spots, wrinkles, firmness, elasticity, and brightening. The formula contains various water-based active ingredients including Licorice Extract, GlucoBright, Vitamin B3, BaicaVital, DMAE, Ume Extract, Repair Activator, Hyaluronic Acid, Aloe Vera Extract, Chamomile Extract, and Vitamin B5.

I would like to confirm the compatibility of these ingredients, especially Vitamin B5 which is alkaline, and the appropriate mixing method. I also want to know if the resulting liquid texture is normal or if it needs adjustment.

Hello! I understand you are looking to create an all-in-one serum for your combination, acne-prone skin to address dark spots, wrinkles, firmness, elasticity, and brightening.

Based on the list of ingredients you provided, including the Vitamin B5 you inquired about, the staff has confirmed that all ingredients are compatible in this formula. Even though Vitamin B5 is alkaline, when mixed with other ingredients that are neutral or slightly acidic, the overall formula will have a pH suitable for the skin.

Your formula includes a variety of ingredients that cover the properties you desire, such as helping to reduce dark spots (e.g., Licorice Extract, GlucoBright, Vitamin B3), reducing wrinkles and firming (e.g., BaicaVital, DMAE, Ume Extract, Repair Activator), increasing elasticity and hydration (e.g., Hyaluronic Acid, Aloe Vera Extract, Vitamin B5), and brightening the skin. It also includes ingredients that help soothe the skin and reduce irritation (e.g., Chamomile Extract, Aloe Vera Extract, Repair Activator), which is suitable for your combination and acne-prone skin type.

Regarding the mixing method, since most ingredients are water-based, you can mix them together directly.

According to the staff's recommendation, if you prefer a slightly thicker, gel-like/creamy serum texture, you can add AnyGel at a concentration of 0.3-0.5%. However, if you do not adjust the texture, the serum will still be functional, although it may be quite liquid like water.

Overall, this formula is good and addresses the skin concerns you have.
