What are the benefits of applying vitamin c topically?

Applying vitamin C topically offers several potential benefits for the skin. Here are some reasons why it is commonly used in skincare:

1. Antioxidant protection: Vitamin C is a potent antioxidant that helps protect the skin against free radicals, which are unstable molecules that can damage cells and contribute to premature aging. By neutralizing free radicals, vitamin C helps prevent oxidative stress and supports healthier-looking skin.

2.Collagen synthesis: Vitamin C plays a crucial role in collagen synthesis, which is the process that helps maintain the skin’s structure, firmness, and elasticity. Collagen is a protein that provides structural support to the skin, and vitamin C is essential for the production and stability of collagen fibers.

3. Brightening and even complexion: Topical vitamin C can help reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone. It inhibits the production of melanin, the pigment responsible for skin color, which can result in a more radiant and even complexion over time.

Sun Damage

4. Sun damage protection: While it is not a replacement for sunscreen, vitamin C can complement sun protection measures. It helps defend the skin against the damaging effects of UV radiation, including sunburn and photoaging. Additionally, it can assist in reducing inflammation caused by sun exposure.

5.Wound healing: Vitamin C supports the skin’s natural healing process by promoting the production of new collagen, which is crucial for wound repair. It may help accelerate the healing of minor abrasions and acne scars.

We are proud to be official stockist’s for Obagi Proffesional-C Serums available in 10%, 15% & 20% concentrations.

If you have sensitive skin or haven’t used a vitamin c serum before then we recommend starting with the 10% concentration and gradually increase it if your skin tolerates it well. Higher concentrations may be more irritating for sensitive skin, so it’s best to proceed gradually to assess how your skin responds.


Does Makeup With SPF Provide Adequate Sun Protection?

Does Makeup With SPF Provide Adequate Sun Protection?

The short answer is no!

During skin consultations/treatments when I ask people if they use SPF they often tell me that they do as it’s in their makeup.Whilst SPF (Sun Protection Factor) in makeup can provide some level of sun protection, the truth is that it’s not sufficient enough protection on its own. The effectiveness of SPF in makeup depends on several factors, including the product’s formulation, application amount, and how well it is maintained throughout the day.

While using makeup with SPF is better than not using any sun protection at all, it is generally recommended to use a dedicated sunscreen alongside your makeup for optimal sun protection. Here are a few reasons why relying solely on SPF in makeup may not be enough:

1. Insufficient amount: Most people do not apply enough makeup to achieve the stated SPF on the product label. To get the full level of protection, you need to apply approximately 1/4 teaspoon of sunscreen to your face, which is a lot more than what most people typically use for makeup application.

2. Inadequate coverage: Makeup with SPF might not provide uniform coverage across the entire face, leaving certain areas vulnerable to sun exposure.

3. Makeup products that claim to have SPF typically provide protection against UVB rays, which are responsible for sunburns and immediate skin damage. UVB protection is indicated by the SPF number mentioned on the product label. However, the level of UVA protection in makeup can vary. UVA rays are also harmful and can cause long-term skin damage, premature aging, and contribute to the risk of skin cancer. To ensure adequate UVA protection, you need to look for “broad-spectrum” sunscreen. Broad-spectrum indicates that the product offers protection against both UVA and UVB rays.

Obagi Sun Shield Tint Broad Spectrum SPF 50 sunscreens

I recommend Obagi Sun Shield Tint Broad Spectrum SPF 50 sunscreens as they use the best of both physical and chemical ingredients to provide broad spectrum protection against harmful UVA/UVB rays, and additionally, defends against Infrared (IR) rays. Available in a Warm or Cool tint to complement the unique undertones of your skin

Is Laser Hair Removal Painful? Exploring the Discomfort and Factors Involved

Wondering about the pain level of laser hair removal? Learn about the potential discomfort, factors that influence pain, and post-treatment effects. Discover how advanced technologies and cooling systems can help minimise any discomfort during the procedure.

Laser hair removal is a popular method for achieving long-lasting hair reduction. While the procedure is generally well-tolerated, the level of pain experienced can vary from person to person. Understanding the factors that contribute to discomfort and the available measures to minimise it can help you prepare for your laser hair removal session.

1. Sensation and Pain Level:

Individuals often describe the sensation during laser hair removal as a mild stinging or snapping feeling, comparable to the snap of a rubber band against the skin. The pain is typically brief, lasting for only a fraction of a second as the laser energy targets the hair follicles.

2. Factors Influencing Discomfort:

  • Individual Pain Tolerance: Each person’s pain threshold is unique, and what may be uncomfortable for one individual could be easily tolerated by another. Factors such as your pain sensitivity and previous experience with hair removal methods can influence your perception of pain during laser treatments.
  • Treatment Area: The sensitivity of the area being treated plays a role in the level of discomfort. Areas with thinner skin or a higher density of nerve endings, such as the bikini line or underarms, may be more sensitive than areas with thicker skin, like the legs.

3. Minimising Discomfort:

Advanced technologies and techniques are employed to minimize pain during laser hair removal. Our Lumenis M22 system, for example, features a built-in cooling system in the handpiece, which helps to alleviate discomfort during the procedure. Additionally, our laser therapists use cooling devices post-treatment to further soothe the skin.Moreover, laser settings can be adjusted according to your comfort level. By working closely with your laser therapist, you can find a balance between effective hair removal and manageable discomfort.

4. Post-Treatment Effects:

After laser hair removal, it is normal to experience some post-treatment effects. These may include temporary redness, swelling, or a sensation similar to a sunburn in the treated area. However, these effects typically subside within a few hours to a couple of days. Applying a cool compress or aloe vera gel can help soothe the skin and alleviate any discomfort.

5. Conclusion:

Laser hair removal may cause some discomfort, but the pain level is generally manageable for most individuals. Factors such as individual pain tolerance and the treatment area can influence the level of discomfort experienced. Advanced technologies, cooling systems, and the ability to adjust laser settings contribute to minimizing pain during the procedure. Don’t hesitate to communicate with your laser therapist about your comfort level to ensure a positive and effective laser hair removal experience.


HIFU vs. RF Microneedling

HIFU vs. RF Micro-needling: Understanding the Differences for Skin Tightening

HIFU and RF Micro-needling are two non-surgical cosmetic treatments aimed at lifting and tightening the skin. While they share a common goal, understanding their differences is crucial. In this article, we will provide a breakdown of the dissimilarities between the two treatments, helping you make an informed decision.

1. Technology and Mechanism of Action:

  • Radio frequency Micro-needling: This treatment combines the benefits of micro needling with radio frequency energy. It utilises a device with tiny needles to create micro channels in the skin, stimulating collagen production and tissue remodelling. Simultaneously, radio frequency energy is delivered to the deeper layers of the skin, promoting further collagen synthesis and tightening.
  • HIFU: High-Intensity Focused Ultrasound employs ultrasound energy to target specific depths within the skin. By focusing high-frequency sound waves on precise areas, HIFU generates heat and creates thermal coagulation zones. These zones trigger collagen production, resulting in skin tightening and a natural healing response.

2. Depth of Treatment:

  • Radio frequency Micro-needling: The depth of treatment can be adjusted based on your desired outcome and the specific skin layer being targeted. At the Cobham Clinic, we offer needle depths ranging from 0.5mm to 1.5mm. This allows us to address both superficial and deeper layers of the skin effectively.
  • HIFU: HIFU primarily targets the deeper layers of the skin, including the superficial muscular aponeurotic system (SMAS) and deeper fascial layers. It can reach depths of up to 4.5mm or even deeper, depending on the treatment area.

3. Skin Concerns Addressed:

  • Radio frequency Micro-needling: This treatment is effective for various skin concerns, such as fine lines, wrinkles, acne scars, uneven skin texture, and mild to moderate skin laxity. It helps improve skin tone and texture by stimulating collagen synthesis and providing skin tightening benefits.
  • HIFU: HIFU is primarily utilised for non-surgical facelifts and skin tightening. By targeting deeper layers of the skin, HIFU stimulates collagen production and tightens the skin, resulting in reduced sagging and enhanced overall facial contours.

4. Treatment Areas:

  • Radio frequency Micro-needling: This versatile treatment can be used on various areas of the body, including the face, neck, décolletage, and body areas with concerns such as stretch marks or scars.
  • HIFU: HIFU is commonly employed for skin tightening and lifting on the face and neck. It can also be used on other body areas where skin tightening or fat reduction is desired.

5. Downtime and Results:

  • Radio frequency Micro-needling: Depending on the depth and intensity of the treatment, downtime can range from a few hours to a few days. Mild redness, swelling, and temporary sensitivity may occur. Results are typically gradual, with noticeable improvements appearing over several weeks as collagen production increases.
  • HIFU: HIFU usually involves minimal downtime, with temporary redness, swelling, or tenderness that subsides quickly. Results are progressive and continue to improve over several months as collagen remodelling takes place.


Both HIFU and RF Microneedling are effective non-surgical treatments for skin tightening, but they differ in terms of technology, treatment depth, targeted concerns, treatment areas, downtime, and results. Consult with a qualified practitioner to determine which treatment is best suited to your specific needs and desired outcome.

Remember, HIFU is ideal for non-surgical facelifts and overall skin tightening, while RF Micro needling excels at addressing various skin concerns and can be used on different areas of the body.


What is the difference between Retinol and Tretinoin?

What is the difference between
Retinol and Tretinoin?

Tretinoin and retinol are both derivatives of vitamin A and are commonly used in skincare products, but they have some differences in terms of their potency and how they affect the skin.

  • Potency: Tretinoin, also known as retinoic acid, is a prescription-strength retinoid that is more potent than retinol. It is typically used to treat acne, reduce fine lines and wrinkles, and improve skin texture. Retinol, on the other hand, is a milder form of vitamin A and is available over-the-counter in skincare products. It is considered a cosmetic ingredient rather than a medication.
  • Conversion: When applied to the skin, retinol undergoes a conversion process within the skin cells to become retinoic acid (the active form of vitamin A). Tretinoin is already in the active form, so it does not require conversion.
  • Availability: Tretinoin is only available with a prescription from a healthcare professional. Here at the Cobham Clinic we are able to prescribe Tretinoin after an in depth skin consultation to ensure that it is safe and effective product choice for you. Following that, we can then decide which is the correct strength and frequency for you. Most people start on Tretinoin 0.05 cream every 2-3 nights. They then work up to a higher frequency and/or strength. However, if  you have more sensitive skin we might start you on a lower frequency and/or lower strength Tretinoin 0.025 cream. On the other hand, if your skin is used to active products, your may decide to start you on Tretinoin 0.1 cream. Ultimately, this treatment will be personalised to your skin and goals. Retinol, however, can be found in various skincare products available over-the-counter, including creams, serums, and lotions. Obagi offers Retinol 0.5, best for those new to skincare or those with sensitive skin, while Obagi Retinol 1.0 is available for those who are already familiar with Retinoids.
  • Skin tolerance: Tretinoin is generally more irritating to the skin compared to retinol. It can cause dryness, redness, peeling, and increased sensitivity, especially when first starting to use it. Retinol, being milder, usually has fewer side effects and is better tolerated by most people.
  • Effectiveness: Due to its higher potency, tretinoin tends to produce more dramatic results in treating acne, reducing wrinkles, and improving skin texture. Retinol may take longer to show visible effects and may be more suitable for individuals with sensitive skin or those looking for a milder approach to skincare.
iIt's important to note that both tretinoin and retinol increase the skin's sensitivity to sunlight, so it's crucial to use them in conjunction with a broad spectrum sunscreen and follow proper sun protection measures.
