Effective Strategies for Treating Acne Scars and Hyperpigmentation

The marks left behind after acne have troubled me for a long time?

Hello, doctor.
I have some questions regarding acne.
During high school, I would only get one or two pimples before exams, but since I started university in Keelung four years ago, I have been experiencing persistent breakouts.
After some time and with skincare and medication, I currently have some red scars and hyperpigmentation (some of which are age spots or sun spots that have been with me for as long as I can remember).
Now, my condition has improved, and I only occasionally get large pimples, but I still have some comedones.
I would like to ask how to treat acne scars and hyperpigmentation.
Should I focus on hydration or brightening? Currently, I am using a topical retinoid.
What would be the best skincare routine for me? Is it acceptable to wear makeup for important occasions? My goal is to look beautiful even without makeup.
Thank you for your guidance.

Acne scars should be assessed as either pigmented scars or atrophic scars, as the treatment methods differ.
Pigmented scars can be treated with ointments, whitening products, whitening treatments, or laser skin resurfacing.
Atrophic scars require dermabrasion or fractional laser treatment.
Tretinoin can still be used as long as there are no side effects, but it is recommended to avoid makeup as much as possible.

More Info

Acne scars and hyperpigmentation can be persistent issues following acne outbreaks, and addressing them effectively often requires a multifaceted approach. Here are some effective strategies for treating acne scars and hyperpigmentation, along with considerations for skincare and makeup.

1. Topical Treatments
- Retinoids (A酸): As you are already using a topical retinoid (A酸), this is a great start. Retinoids promote cell turnover, helping to fade hyperpigmentation and improve skin texture. They can also prevent new acne from forming. However, they can cause dryness and irritation, so it's important to use them as directed and to monitor your skin's response.

- Vitamin C: Incorporating a Vitamin C serum can help brighten the skin and reduce the appearance of dark spots. Vitamin C is an antioxidant that can also protect the skin from UV damage and promote collagen production.

- Alpha Hydroxy Acids (AHAs): Products containing AHAs, such as glycolic acid, can help exfoliate the skin and improve the appearance of scars and pigmentation. They work by removing dead skin cells and promoting new skin growth.

- Beta Hydroxy Acids (BHAs): Salicylic acid is a BHA that can penetrate pores and help clear out excess oil and dead skin cells, which can be beneficial for preventing future breakouts.

2. Professional Treatments
- Chemical Peels: These treatments involve applying a chemical solution to the skin to exfoliate and improve texture and pigmentation. They can be tailored to your skin type and concerns.

- Microneedling: This procedure involves using fine needles to create micro-injuries in the skin, which stimulates collagen production and can improve the appearance of scars.

- Laser Treatments: Various laser therapies can target pigmentation and improve skin texture. Consult with a dermatologist to determine the best option for your skin type.

- Dermal Fillers: For deeper scars, fillers can be used to plump up the skin and reduce the appearance of scars.

3. Sun Protection
Using a broad-spectrum sunscreen daily is crucial, especially when using treatments that can make your skin more sensitive to the sun. Sun exposure can worsen hyperpigmentation, so protecting your skin is essential for effective treatment.

4. Moisturization
Maintaining skin hydration is important, especially when using retinoids and other active ingredients that can be drying. Look for non-comedogenic moisturizers that won't clog pores. Ingredients like hyaluronic acid can help retain moisture without causing breakouts.

5. Makeup Considerations
If you have important events and want to wear makeup, consider using products that are non-comedogenic and suitable for sensitive skin. A good primer can help create a smooth base, and a lightweight foundation can provide coverage without feeling heavy. Look for products that contain skin-beneficial ingredients.

6. Lifestyle Factors
- Diet: A balanced diet rich in antioxidants (fruits and vegetables) can support skin health. Staying hydrated is also important.

- Stress Management: Stress can exacerbate acne, so incorporating stress-reducing practices like exercise, meditation, or hobbies can be beneficial.

Conclusion
Achieving clear skin and reducing the appearance of scars and hyperpigmentation is a gradual process that requires patience and consistency. It's important to consult with a dermatologist to tailor a treatment plan that suits your specific skin type and concerns. They can provide guidance on the best combination of topical treatments, professional procedures, and skincare routines to help you achieve your goal of beautiful skin, even without makeup.
