Many people use the same products to treat both active acne and acne scars. However, these are two different skin concerns that need different treatments. Understanding the difference can save you time, money, and frustration in your journey to clear skin.
Active acne means you currently have pimples, blackheads, whiteheads, or cysts on your skin. These are active breakouts that are still forming.
According to dermatology research, active acne happens when four things occur together:
Research shows that hormones, stress, diet, and skincare products can all affect these factors. In Singapore’s hot and humid climate, sweat and environmental pollution can also make acne worse.
Non-inflammatory Acne:
Inflammatory Acne:
Studies show that inflammatory acne (especially nodules and cysts) is more likely to cause permanent scars.
Acne scars are permanent marks left on your skin after acne has healed. Unlike active acne, scars do not go away on their own. They are the result of damage to your skin tissue during the healing process.
When acne inflammation goes deep into your skin, it damages the skin tissue and collagen. Research shows that scars form in two ways:
Studies confirm that severe inflammatory acne, picking or squeezing pimples, and delayed treatment increase the risk of scarring.
Atrophic Scars (Depressed Scars)
These are the most common type of acne scars. They appear as depressions or pits in the skin:
Hypertrophic Scars (Raised Scars)
These appear as raised, thick areas on the skin. They form when your body produces too much collagen during healing. According to research, hypertrophic scars are less common than atrophic scars and often appear on the chest, back, and shoulders.
Post-Inflammatory Hyperpigmentation (PIH)
Technically not a scar, but many people call these dark marks “acne scars”. PIH is flat, dark-coloured spots left after acne heals. Studies show that PIH is particularly common in Asian skin. Unlike true scars, PIH usually fades over time (6 to 12 months) but can be treated faster with proper care.
Understanding these differences helps you choose the right treatment.
| Feature | Active Acne | Acne Scars |
| What it is | Current breakouts and pimples | Permanent marks after acne heals |
| Causes | Bacteria, oil, blocked pores, inflammation | Damage to skin tissue during healing |
| Appearance | Red, raised, may have pus | Pits, depressions, or raised areas |
| Changes | Comes and goes, can heal | Permanent without treatment |
| Treatment goal | Kill bacteria, reduce oil and inflammation | Rebuild skin tissue, stimulate collagen |
| Treatment type | Antibacterial, anti-inflammatory | Collagen-stimulating, resurfacing |
Dermatology research makes this clear: active acne and scars have different causes, so they need different solutions.
Treatments for active acne work to:
Treatments for acne scars work to:
Studies show that using the wrong treatment wastes time and money. For example, acne-fighting products like benzoyl peroxide will not improve acne scars because scars are not caused by bacteria.
LED (light-emitting diode) therapy is a non-invasive treatment that uses different wavelengths of light. Research published in dermatology journals confirms that LED therapy is safe and effective for both active acne and acne scars, but you need the right colour for your concern.
How It Works:
Blue light (around 415nm wavelength) penetrates into your pores and kills C. acnes bacteria. Studies show that these bacteria produce molecules called porphyrins. When blue light hits porphyrins, it creates a reaction that destroys the bacteria.
Research published in medical journals shows that blue LED therapy:
What to Expect:
During treatment, you sit or lie down while blue LED light shines on your skin for 15 to 20 minutes. Most people need 2 to 3 sessions per week. The light feels warm but does not hurt. There is no downtime after treatment.
How It Works:
Red light (around 660nm wavelength) penetrates deeper into your skin than blue light. It stimulates the cells that produce collagen (fibroblasts) and increases blood flow to the area. According to research, this helps:
Studies show that red LED therapy:
What to Expect:
Treatment is similar to blue light therapy but may last slightly longer (20 to 30 minutes). You need regular sessions, usually 2 to 3 times per week initially, then maintenance sessions. Results appear gradually over several months as new collagen forms.
Many people have both active acne and acne scars. Research shows that combining blue and red LED therapy in one session can address both concerns:
At Sage & Fawn, we offer professional LED therapy as part of our comprehensive acne treatment approach.
AromaClear Treatment
Our organic acne facial uses natural essential oils and plant extracts that have antibacterial and anti-inflammatory properties. Research on aromatherapy shows that certain essential oils can reduce acne-causing bacteria without the side effects of harsh chemicals.
This treatment is gentle enough for sensitive skin but effective for oily and acne-prone skin. It deeply cleanses pores, reduces inflammation, and calms irritation.
Topical Treatments for Home Use:
Chemical Peels
Professional chemical peels use acids to remove the top layers of skin, encouraging new skin growth. Research shows they are effective for:
However, studies warn that chemical peels must be done carefully on Asian skin to avoid causing more pigmentation. This is why professional application is essential.
Microneedling
This treatment uses tiny needles to create controlled micro-injuries in the skin. Research shows this stimulates collagen production. Studies report 30% to 70% improvement in acne scars after a series of treatments.
Topical Treatments for Home Use:
Managing expectations is important for successful treatment.
Research shows that you must be patient. If you stop treatment too early, acne often comes back.
Studies show that treating acne scars takes longer than treating active acne because your skin needs time to rebuild collagen. Deep scars may need multiple rounds of treatment.
Dermatology research worldwide agrees that preventing acne scars is easier than treating them.
While treating active acne:
Stop guessing about what treatment you need. At Sage & Fawn, we assess your skin to determine whether you need acne treatment, scar treatment, or both. Our professional LED therapy combines blue and red light for comprehensive care.
With over 30 years of combined experience, we understand Asian skin and know how to treat acne and scars safely and effectively.
Always treat active acne first. Research shows that ongoing inflammation can cause more scarring. Once your acne is under control and you have no new breakouts for at least 6 to 8 weeks, you can focus on treating existing scars. Some treatments (like red LED therapy and certain chemical peels) can address both concerns at once, but controlling active acne is the priority.
LED therapy is very effective but works best as part of a complete treatment plan. Studies show that combining LED therapy with proper skincare, lifestyle changes, and sometimes other professional treatments gives the best results. For severe acne, you may also need prescription medication. Think of LED therapy as a powerful tool in your treatment toolkit, not the only tool.
At-home LED devices use lower power than professional equipment, so they take longer to show results. Research shows that professional LED devices are more effective because they use stronger light intensity. However, at-home devices can be useful for maintenance between professional sessions. If you choose an at-home device, make sure it is FDA-approved or meets safety standards.
Post-inflammatory hyperpigmentation (dark marks) often fades over 6 to 12 months without treatment, though it may take longer. However, true acne scars (pitted or raised scars) are permanent and will not fade on their own. Studies show that these scars need active treatment to improve. The good news is that most acne scars can improve significantly with proper treatment, even if they do not disappear completely.
Yes, but Asian skin needs special care. Research shows that Asian skin is more prone to post-inflammatory hyperpigmentation, so treatments that are too aggressive can make things worse. This is why it is important to see professionals who understand Asian skin. At Sage & Fawn, we use treatments proven safe for Asian skin and adjust intensity based on your individual needs.
Costs vary depending on the type and severity of scars, and the treatment method used. LED therapy is generally more affordable than lasers or surgical treatments. A single LED therapy session typically costs less than $100 in Singapore, but you need multiple sessions. Deep scars may need more intensive (and expensive) treatments like microneedling or laser therapy. During a consultation, we can give you a clear treatment plan with costs based on your specific needs.
Understanding the difference between active acne and acne scars is the first step to clear skin. Active acne needs antibacterial and anti-inflammatory treatments, while acne scars need collagen-stimulating and resurfacing treatments. LED therapy offers a safe, effective way to address both concerns using the right colour of light for each problem.
Remember that treating acne and scars takes time. Research shows that consistency in treatment and prevention is more important than finding a “miracle cure”. With the right approach, most people see significant improvement.
At Sage & Fawn, we combine advanced technology like LED therapy with 30 years of skincare expertise to help you achieve clear, healthy skin. Whether you are dealing with active breakouts, acne scars, or both, we create personalised treatment plans that work.
Do not let acne or acne scars affect your confidence any longer. Book a consultation today and take the first step toward the clear skin you deserve.
