Post-acne refers to acne aftereffects such as scars and pigmentation. Treatment includes the use of lasers, chemical peels, and microneedling to improve skin texture and even out tone. These procedures help stimulate skin regeneration and reduce the visibility of scars. The effect becomes noticeable after several sessions.
QUESTIONS:
- Which types of lasers are most effective in treating post-acne scars, and how do they work on the skin?
ANSWER: The most effective lasers for treating post-acne scars are fractional CO2 and erbium lasers. Fractional CO2 lasers remove thin layers of skin and stimulate deep regeneration, improving texture and reducing scars. Erbium lasers are less aggressive and suitable for more sensitive skin, promoting renewal without significant damage.
- What are the main principles of chemical peels in post-acne treatment, and which preparations are typically used for this purpose?
ANSWER: Chemical peels work through the application of acids such as glycolic, salicylic, or trichloroacetic acid, which remove the top layer of skin and accelerate cell renewal. This helps soften scars and even out skin tone. Peels also help reduce pigmentation associated with post-acne.
- What are the indications and contraindications for microneedling in treating acne aftermath?
ANSWER: Microneedling is recommended for improving skin texture, reducing scars, and stimulating collagen. Contraindications include active inflammatory skin processes, eczema, dermatitis, herpes, as well as certain autoimmune diseases and tendency to form hypertrophic scars.
- How many treatment sessions are typically required to achieve noticeable results in post-acne treatment, and what is the interval between sessions?
ANSWER: Usually 3 to 6 sessions are required to achieve noticeable results. The interval between sessions is 4-6 weeks, allowing the skin to recover and renew after each procedure.
- What additional skincare measures can be recommended after procedures to maximize post-acne treatment results?
ANSWER: After procedures, it’s recommended to use moisturizers, products with antioxidants, and high SPF sunscreens to protect the skin from UV rays. It’s important to avoid aggressive cosmetic procedures and physical impact on the skin (e.g., scrubs) for several days after treatment. It’s also necessary to maintain skin cleanliness and avoid using comedogenic products.
