La Roche-Posay Effaclar Ultra Concentrated Serum is designed to improve overall skin texture while simultaneously targeting blackheads, blemishes, and marks. Suitable for acne-prone skin with ageing concerns. Key ingredients include Glycolic Acid, Salicylic Acid, and LHA (Lipo-Hydroxy Acid), which help to unclog pores, smooth the skin’s surface, and increase cellular regeneration overnight. Niacinamide is known to improve elasticity, pigmentation and enhance skin barrier function. Due to its unique mineral composition, La Roche-Posay Thermal Spring Water has soothing properties that have been shown to reduce skin irritations. Contains a fragrance. Dr Webster’s Recommendation: The Effaclar Serum formula contains complementary exfoliating ingredients that have been demonstrated to improve efficacy while soothing ingredients decrease skin irritations. This innovative formula is ideal for adult-acne patients as it will have anti-ageing benefits, whilst treating blackheads and blemishes. Exfoliation is key for unclogging pores, improving acne scarring, and brightening the skin’s overall complexion and appearance. Safety during pregnancy has not been established.
