Erase Acne Scars with Rejuran S (And Three Other Remedies You Can Also Try)

Table Of Contents

Acne is a skin condition that impacts millions of people and develops when sebum, dead skin cells, or bacteria plug the hair follicles, leading to inflammation. While this condition often affects adolescents the most, it is also common among adults, resulting in red, painful pustules that leave behind deeply rooted scars where clearing can get frustrating and overwhelming.

The good news is that with ClearSK's acne scars treatment in Singapore, treating and healing even the most stubborn acne scars are entirely possible. Revolutionary and effective with breakthrough results, Rejuran S is the solution to restoring your confidence with flawless, clear skin.

In this article, we share some information on acne, including prevention measures and its treatment options.

Acne Scars: How Do They Form?

When acne penetrates deep into the skin tissue, it causes damage to the deep layers of your skin. This inflammation causes your acne pores and the surrounding tissue to swell and break down, resulting in scarring. Our body then works incredibly to naturally repair itself and form new skin tissue in the area where the pimple was.

As the immune system directs white blood cells in surplus towards the pimples area for healing, the skin produces new collagen that will serve as the foundation of the new skin tissue. When white blood cells and collagen production is excessive, the extra cells get transformed into a scar. The deeper the damage caused by acne, the higher its chances of leaving permanent scars, even after the pimples heal. This can often take a toll on one’s emotional wellbeing and confidence.

Mild, moderate, or severe acne can cause different types of scars. This is why it’s important to first determine the severity of one’s acne when attempting to treat marks or spots left behind.

How Severe Can Acne Get?

  • Mild acne: Mild acne is characterized by blackheads, whiteheads, a few pustules and papules.
  • Moderate acne: Moderate or pustular acne mostly affects the face, causing multiple pustules and papules to appear.
  • Moderately severe acne: This nodulocystic acne affects the face but may extend to the chest and back. It is indicated by the presence of many pustules, papules, and even the occasional inflamed nodules.
  • Severe acne: Severe nodulocystic acne is distinguished by numerous large, inflamed, painful pustules and nodules.

Types of Acne Scars

Some scars are depressed and sit under the skin's surface, while others are raised and sit above the skin. We discuss each one of these types here below;

Atrophic Scars


Atrophic scars are mainly caused by severe acne. These scars are depressed and flat, sitting below the top layer of the skin. The appearance of these scars varies from person to person, with the three main types being boxcar, ice pick, and rolling scars.

  • Boxcar Scars: Boxcar scars appear like broad, shallow, box-like depressions with sharply defined edges. They occur either oval or round in shape, typically measuring with a length of 1.5mm to 4mm. These scars form mainly on areas where the skin is relatively thick, like the lower area of the cheeks and jaw. Other causes of boxcar scars include chickenpox and varicella that often result in red, itchy blisters. These scars are relatively easier to treat using skin resurfacing treatments.
  • Ice Pick Scars: Ice pick scars are small and narrow indentations common on the cheeks and forehead areas where the skin is considerably thinner. The v-shaped scars are less than 2mm wide and appear to point down, deep into the skin, resembling the marks left by a long-thin instrument – like an ice pick. These deep scars are challenging to treat, requiring aggressive, persistent treatment.
  • Rolling scars: Rolling scars have sloping edges and varying depths, but are generally shallow. They make the skin appear uneven and even wavy, with scars as wide as 5mm. This type of scarring is common and often develops in areas with thick skin, like the lower cheeks and the jaw area.

Hypertrophic and Keloid Scars


Hypertrophic and keloid scars are formed after the skin heals from acne lesions and fibrous tissue of the skin grows. This scarring is usually raised over the surrounding skin surface to appear as lumps on areas where your acne pimples once were. Hypertrophic scarring affects your jawline, back, chest, shoulders and are most common among people of colour.

These scars may feel itchy and painful. While your hypertrophic scars resemble the exact size of the acne pimple that caused them, keloid scars appear larger, growing beyond the original acne spot.

Other Marks Left by Acne


Some acne lesions leave marks on the skin that aren't necessarily scarring, but may look darker or discoloured compared to your normal skin tone. This condition is referred to as post-inflammatory hyperpigmentation. With time and proper sun protection, your hyperpigmentation can clear without any acne scar removal treatment, returning the skin to its natural colour. Persons of colour and those that pick their acne are more likely to experience hyperpigmentation.

Should you wish to hasten the brightening process and rejuvenate your lacklustre complexion to a desirable glow, ClearSK's Rejuran Healer Injectable can help you with this process. You will not only achieve clear, glass-like skin, but also improve your skin’s elasticity, texture, and reduce appearances of any fine lines as well as wrinkles.

Treating Acne using Rejuran S

With ClearSK’s Rejuran S treatment, you can say goodbye to acne scars. It is a non-invasive procedure that is quick, safe, and doesn't require anaesthesia or surgery.

Rejuran S contains Polynucleotide (PN) from salmon DNA. The concentrated and viscous solution is administered by injecting it directly into your skin area where acne scars are present. The Rejuran then stimulates collagen regeneration and remodelling of your dermis, filling up sunken scars and improving the appearance of depressed ones. To soothe any discomfort you may experience during the procedure, we apply a numbing cream to the area of concern. This then allows for minimal pain perception.

After a procedure, it is normal to find small bumps over the treated skin area. But don’t worry, we will supply you with an intensive recovery cream that can be used to effectively massage down the bumps. Any needle marks or bruising should recover within 5-7 days.

The Rejuran S price is fair, quoted at just S$298 – a small price to pay to never feel insecure about your looks, with or without makeup!

Is Rejuran S effective?


While other treatments may only achieve 40-60% skin recovery success, Rejuran S's ability to boost skin healing and remodelling of collagen makes it possible to achieve 80% skin improvement. Patients have reported a glow and radiance to their skin, including smoother skin, reduced fine lines, and even improved hydration.

How long does Rejuran S take to work?

You will need at least 3-4 treatments, each with a month interval, and noticeable effects almost immediately following the 1 hour procedure. Depending on your skin and the severity of scarring, more sessions may be required.

How long do the effects of Rejuran S last?

The effects of Rejuran S are permanent, but it is recommended to return for another session once every 6-12 months until your existing marks are completely healed. This would allow room for our medi-advisors to successfully target deep and depressed scars for consistent improvement in scarring treatment.

How can I maintain the effects of Rejuran S?

While the Rejuran S treatment is highly effective at increasing your skin cell turnover rate to remove the appearances of acne scarring, the treatment is not capable of preventing further development of acne. Acne breakouts may be inevitable and difficult to avoid, but the following steps and measures can help reduce your chances of waking up to a new pimple or making matters worse;

  • Wash your face regularly with a mild facial cleanser and warm water to remove excess oil as well as dirt that could clog your skin pores, leading to acne. Avoid harsh irritants or scrubbing that can aggravate your skin. This can often cause inflammation that worsen your acne breakouts.
  • Keep your hands away from your face to reduce the chances of bacteria transfer. Also, refrain from picking or popping your pimples as doing so could spread the bacteria and pus from the infected pore to surrounding pores in the area.
  • To reduce your breakouts, use over-the-counter topical treatments, serums, and creams on acne-prone areas. Make sure to keep an eye out for acne treating ingredients such as benzoyl peroxide, salicylic acid, tea tree oil, and adapalene.
  • Cut down on foods with a high glycemic index that are linked to breaking out – like cakes, cookies, and pies.
  • Consider visiting an aesthetician or dermatologist for light or laser therapies that can help reduce acne-causing bacteria, P. acne, on your skin.
  • Make sure to slather on your oil-free sunscreen with at least 30 SPF when you step outdoors. Sunburns can often worsen your acne by causing overproduction of oils.

Are there any alternatives to Rejuran S?
