Recommended Moisturizer Formulation for Oily, Dehydrated Skin with Red Acne Marks

Based on your skin condition after Acnotin treatment, which is oily, dehydrated, prone to clogged pores, and has red acne marks with some depressed texture, it is important to use a gentle moisturizer that strengthens the skin barrier and reduces redness without causing breakouts.

As previously advised, consistent moisturizing is key to helping your skin recover and regulate oil production. Using a suitable moisturizer will also help your skin tolerate active treatments like Retin-A better.

For your skin type, a lightweight, water-based formula is recommended to avoid clogging pores. Consider formulating a serum or gel using the following ingredients:

• Hyaluronic Acid Gel Base: Provides a light, non-greasy base for hydration.
• Safe-B3™ (Vitamin B3, Niacinamide): Helps reduce redness, strengthens the skin barrier, improves skin texture, and can help regulate oil production. Use at a concentration of 5-10%.
• Panthenol (Vitamin B5): A great humectant that soothes skin, reduces inflammation, aids in wound healing, and strengthens the skin barrier. Use at a concentration of 1-3%.
• Pure-TECA™ Centella Asiatica Extract (TECA 95%, CICA): Highly effective in reducing inflammation and irritation, which is beneficial for calming red acne marks and supporting skin repair. Use at a concentration of 0.1-1%.

Example Formulation (Water-Based Serum/Gel):

1. Start with Hyaluronic Acid Gel Base.
2. Add Safe-B3™ (Vitamin B3, Niacinamide) powder and mix until dissolved.
3. Add Panthenol (Vitamin B5) powder and mix until dissolved.
4. Disperse Pure-TECA™ Centella Asiatica Extract into the mixture (it does not fully dissolve in water-based formulas but can be dispersed evenly).
5. Mix thoroughly.

This formulation focuses on hydration, barrier repair, and reducing redness, which aligns with your current needs. It is water-based and uses ingredients known to be suitable for acne-prone and sensitive skin.

Regarding sunscreen, it is crucial for preventing red marks from darkening into post-inflammatory hyperpigmentation. Look for sunscreens specifically labeled as "non-comedogenic" or "for acne-prone skin" and test a small area first to ensure it doesn't cause breakouts.
