PATIENT BENEFITS

• Gentle chemical exfoliant
• Improves skin tone & texture
• Helps unclog pores and prevent breakouts
• Erases fine lines
• Fades epidermal pigmentation
• Promotes hydration levels
• Helps decrease sensitivity to topical irritants and improve stratum corneum barrier function


PRODUCT USAGE

• The Skin Refining Serum is normally used at night, after cleansing and before moisturisation
• Patients will experience a tingling or prickling sensation upon application of the product. This quickly subsides. On subsequent applications, this sensation will become less pronounced.
• Skin Refining Serum should be left on the skin (not rinsed off).
• Patients may notice the stinging sensation temporarily returns when they apply moisturiser over the Skin Refining Serum. This is caused by water on skin temporarily lowering pH. This sensation will also quickly subside.

FAQ

Q How does Skin Refining Serum work?
A Skin Refining Serum helps exfoliate by lowering skin pH, activating the enzyme Cathepsin-D, which releases excess surface corneocytes.

Q What is the pH of Skin Refining Serum?
A The pH is 3.8 to 4.1.

Q What is the balance of AHA and BHA in Skin Refining Serum?
A Skin Refining Serum contains 18% hydroxy acids –13% AHA (hydrophilic exfoliant) and 5% BHA (lipophilic exfoliant).

Q Why is exfoliation so important?
A Exfoliation is important for cell differentiation, the process by which keratinocytes migrate and transform to construct the stratum corneum. As we age, the rate at which keratinocytes migrate slows considerably. This results in a tired complexion, and can also have negative consequences for conditions such as skin cancer. Exfoliation helps to normalise the speed of the differentiation process, resulting in healthier, fresher skin cells on the surface more often.
Regulation and enhancement of exfoliation may improve many skin conditions including melasma, acne and rosacea.
