Skincare Advice Summary

Based on the conversation, here is a summary of the advice regarding your facial and body skincare concerns while using Retin-A:

Facial Skin

• Using Retin-A: Since you have just started using Retin-A 0.025%, it is recommended to continue using it for about 2 weeks and observe your skin's condition. If your skin becomes dry or peels, you should add moisturizing products. If your skin remains balanced and doesn't show dryness or peeling, additional moisturizing might not be necessary unless you have other specific goals like brightening or anti-aging.
• Your Proposed Formulas: The staff indicated that the formulas you proposed for day (Pure Aloe Vera Gel base with Azelaic Acid, Sea Kelp Bioferment, Licorice Root Extract, Green Tea Extract, Vitamin B3) and night (Double Hyaluronic Gel base with Azelaic Acid, Sea Kelp Bioferment, Licorice Root Extract, Vitamin B3, Gotu Kola, Allantoin) can be used.
• Staff's Specific Recommendation for Face: If you need additional care, the staff specifically recommended a formula containing Vitamin B3 4% + N-Acetyl Glucosamine 4% + Vitamin B5 3%. They also suggested adding Licorice Extract 1% to help control oiliness if needed.
• Using Other Products with Retin-A: While using Retin-A, you should avoid using any products that could cause additional irritation to your skin. If your skin is dry or peeling, focus on sufficient moisturizing. Regarding pore-tightening creams/lotions or toners for clogged pores, the advice is to be cautious and avoid them if they cause further irritation.

Body Skin

• Addressing Dryness and Whitening: For your dry body skin that you wish to make more moisturized and brighter, the staff recommended using Vitamin B3 + N-Acetyl Glucosamine + Vitamin B5. These ingredients can help provide moisture and brighten the skin to a certain extent.
• Mixing Ingredients: Regarding mixing Vitamin B3 and Glucosamine (and Vitamin B5) directly into an existing cream, the staff suggested making a gel with these ingredients instead and referred to the forum for instructions on how to mix them. This implies that simply adding them to any cream might not be the correct method and formulating them into a suitable base like a gel is recommended.

To make a gel for body skin with the recommended ingredients (Vitamin B3, N-Acetyl Glucosamine, Vitamin B5), you would typically need a gel base (like Hyaluronic Acid Gel Base) and then incorporate the active ingredients at the recommended concentrations (Vitamin B3 4%, N-Acetyl Glucosamine 4%, Vitamin B5 3%). Instructions for mixing these ingredients into a gel base can usually be found in the formulation guides or forums provided by the supplier.
