Can I use Deriva CMS gel for my acne marks? Also, is it safe to apply it all over my face to help with the marks? I'm really hoping it works and need some advice. Please let me know soon.

Suitability for a 26-year-old female:
Yes, Deriva CMS gel is generally safe for adults, including women in their mid-20s, to use for acne and acne marks.

Application:
Apply a thin layer once daily to affected areas. Be cautious with sensitive skin and avoid applying all over the face initially.

Precautions:
a. Start with a small amount to test skin reaction.
b. Avoid using other harsh skincare products simultaneously.
c. Use sunscreen during the day, as adapalene can increase sun sensitivity.

Consultation:
Consult a dermatologist to ensure it suits your skin type and condition.

Adverse Reactions:
If you experience redness, excessive dryness, or irritation, discontinue use and seek medical advice.
