SkinCeuticals’ global scientific director Megan Manco answers your questions on the new Glycolic 10 Renew Overnight
As we know, glycolic acid is a leading anti-ageing ingredient clinically proven to address uneven skin tone, dullness, texture, fine lines and wrinkles. However, its topical efficacy depends on the bioavailable concentration and vehicle used, a detail not commonly considered in many glycolic-based formulations. In fact, integrating glycolic acid in a pH-regulated topical formulation may largely neutralise the acid, attenuating its performance. For example, a concentration of 10% glycolic acid at a pH of 4 has an active level of 40.3%. This means that 40.3% of the 10% is available, equating to a free acid value of only 4.0% glycolic acid. For the first time, SkinCeuticals’ Glycolic 10 Renew Overnight delivers a ‘true’ active level of 10% glycolic acid for the most effective solution to ageing, dull skin. It is formulated at a concentration of 14.6% with a pH of 3.5 to deliver this true 10% active level. Another common drawback of many topical glycolic acid-based creams and lotions is skin irritation and discomfort. To counteract this, Glycolic 10 Renew Overnight has been formulated with a soothing complex to form a protective, breathable layer to help lock in hydration and provide comfort.
SkinCeuticals has harnessed 10% free glycolic acid, an optimised level of glycolic acid tolerable for nightly use. 10% glycolic acid is the ideal concentration, efficiently penetrating the epidermis and disrupting cellular cohesion to promote desquamation and increase cellular turnover. Weaker glycolic concentrations (4%) provide minimal exfoliation, whereas stronger concentrations (20%) require administration by a practitioner, and generally cause irritation. Glycolic 10 Renew Overnight has also been synergistically blended with 2% phytic acid which provides comprehensive exfoliation, promoting skin clarity and brightness.
Consumer interest in ‘glowing skin’ has grown – with a +50% increase in global Google searches relating to glow and glycolic between 2016 and 2017. While make-up provides a temporary solution, consumers are increasingly looking to high-quality skincare to achieve this long-lasting ‘glow’. Glycolic 10 Renew Overnight meets this consumer demand by delivering a permanent solution for a lasting ‘glow’, as well as prolonging the effects of in-clinic procedures. Finally, it offers a solution against decelerated cellular turnover associated with photodamage.
Yes – Glycolic 10 Renew Overnight is well suited to treating normal, oily, dry, and combination skin types. Due to the effective concentration of glycolic acid, the recommended protocol is to pre-condition skin by limiting initial use to once every other evening to avoid any initial skin sensitivity. After one week, usage may be increased to every evening, or as tolerated, to deliver the best results. As with other glycolic products, a daytime sunscreen should always be used in conjunction to protect from sun damage. For those using a retinol-based product as part of a night time regimen, we recommend alternating between the two products.
At SkinCeuticals, we believe that healthy, glowing skin is the foundation for every successful aesthetic procedure – therefore Glycolic 10 Renew Overnight is the ideal at-home product to amplify the results from aesthetic procedures, including chemical peels and injectables, as well as improving the overall quality of the skin. By minimising fine lines and wrinkles and improving skin texture and tone (‘glow’), Glycolic 10 Renew Overnight can enhance the effect of in-clinic procedures and provide an effective daily homecare regimen to patients in between clinic visits.
