Understanding Stretch Marks and Their Treatment Options
Stretch marks, also which are often referred to as striae, are a common concern for many individuals. For some, they are a symbol of life’s changes and a testament to the body’s resilience. For others, they can be a source of self-consciousness and a desire to conceal or eliminate them. The question remains: can stretch marks truly be removed, or are the various treatments just a waste of time and money?
Dr. Immaculate Clare, a dermatology pharmacist and cosmetic scientist at Humane Pharmaceuticals, explains that three in five women experience stretch marks. This is largely due to the rapid expansion of the skin, which disrupts the dermis—the middle layer of the skin. This disruption leads to the breakdown of collagen and elastin fibers, resulting in stretch marks.
While stretch marks do not pose any health risks, they can have a significant psychological impact, especially in today’s social media-driven world. “It is not a medical condition,” Dr. Clare notes, but it can affect self-esteem from an aesthetic perspective, prompting many to seek ways to improve their skin’s appearance.
Topical Treatments: Affordable and Accessible
Most people turn to topical solutions because of their affordability and ease of access. These treatments typically range between Sh2,500 and Sh3,200 and can be found in pharmacies and online platforms. They are also simple to incorporate into daily skincare routines.
However, not all topical treatments are effective for every type of stretch mark. “They can help fade the marks, but only when they are in the initial stage, which is known as the active stage, where they appear red or purplish in color,” Dr. Clare says. Once they reach the mature stage, topical solutions are largely ineffective.
For better results, Dr. Clare recommends treatments with specific ingredients such as tretinoin (a prescription retinoid), centella asiatica (commonly known as cica), and hyaluronic acid. These are considered the gold standards in topical treatments due to their clinical effectiveness.
Studies show that a tretinoin concentration of 0.1 percent can reduce the width and length of stretch marks by boosting collagen production and increasing cell turnover. However, it is important to note that tretinoin is strictly off-limits during pregnancy.
Centella asiatica stimulates collagen while preventing the formation of new marks, and hyaluronic acid improves skin hydration and elasticity, supporting the skin as it stretches. Despite these benefits, results take time. Consistent application—two to three times a day—for at least eight to 12 weeks is typically required before any significant change is observed.
In contrast, widely marketed moisturizers like shea and cocoa butter, and humectants like glycerin and aloe vera, do not remove stretch marks. While they may improve the suppleness of the skin, there is no clinical evidence to support their ability to remove stretch marks.
Clinical Treatments: More Intensive and Effective
For those who find topical treatments insufficient, clinical alternatives such as laser therapy and microneedling offer more targeted and intensive approaches. These treatments penetrate deeper into the dermis, making them more effective than topical solutions.
Emily Otieno, an aesthetic nurse at Revive Aesthetics Kenya, notes that interest in stretch mark removal has grown significantly. “We would see one or two clients in a month, but now we are seeing five or more, and the numbers keep increasing as people learn that there are options,” she says.
The treatment involves numbing the area before applying the laser to minimize discomfort. While generally non-invasive, it is not without risks. Some clients may experience redness, swelling, and blistering, which subside over time. Those with sensitive skin may also face hypersensitivity around the treatment area, and improper aftercare could lead to hyperpigmentation or minor burns and scarring.
Not everyone is eligible for these treatments. Pregnant and breastfeeding mothers, people with overly sensitive skin, and immunocompromised patients are typically excluded. Safety is a top priority.
Not for Everyone: Eligibility and Costs
Stretch mark removal accounts for 10 to 15 percent of Revive Aesthetics’ total revenue, with each session priced at Sh3,500. Clients can opt for discounted packages by committing to multiple sessions.
Margaret Musyoka, an esthetician at Skinsol Aesthetics clinic, says demand has grown by as much as 70 percent over the past six years, driven by changing lifestyles. “Pregnancy is a major cause of stretch marks, but it’s not the only one,” she says. “We are seeing more clients coming in because of weight changes, hormonal fluctuations and even muscle growth.”
While women aged 25 to 45 form the bulk of clients, men are also increasingly seeking treatment. Common treatment areas include the arms, thighs, and abdomen.
Microneedling: A Targeted Approach
Microneedling, which uses needles to create controlled trauma and stimulate repair, is another popular treatment option. Like laser treatment, it is not a quick fix and does not fully remove stretch marks. “There’s no way to remove stretch marks 100 percent. We can minimize their appearance, but they don’t fade completely,” Margaret says.
Results vary depending on skin type, severity, and collagen production. Prices at the clinic start from Sh6,500 per session, depending on severity.
Aftercare and Prevention
Aftercare is critical, with clients advised to avoid direct sun exposure, use sunscreen, keep the skin moisturized, and avoid harsh products or scrubbing. Prevention also plays a role through proper diet and hydration.
“Generally speaking, antioxidants are scientifically proven to promote the production of collagen in the body,” Dr. Clare says. “Keeping the skin moisturized and hydrated supports its elasticity, preventing the breakage of skin fibres.”
