PHA 5% Exfoliating Lip Serum is a gentle chemical-based exfoliator for lips with 5% gluconolactone and 1.5% alpha hydroxy acids to smooth and hydrate lips. Gluconolactone is a polyhydroxy acid (PHA) that works to dissolve the structures that hold dead skin cells together. Due to their larger molecular weight, PHAs work on the surface of the skin to offer mild exfoliation, making them suitable for sensitive skin.
This formulation also includes a high concentration (>50%) of glycerin to improve hydration and retain moisture as well as ectoin to support the skin barrier and offer long-term hydration. It also contains a black carrot extract which is known for its antioxidant properties and provides a mild pink colour to the formulation. This plant-derived ingredient may contribute to colour variations in the product ranging from vivid pink to pale peach however should not impact efficacy.
PHA 5% Exfoliating Lip Serum helps to promote skin renewal on the lips to improve their overall appearance and texture over time and can be layered under Squalane + Amino Acids Lip Balm to gently remove dry, dead skin and hydrate lips overnight.
FAQs
You have questions, we have answers.
What causes breakouts and acne?
Breakouts and acne can result from excess oil production, clogged pores, hormonal fluctuations, stress, or using products that are not suitable for the skin type. A consistent routine using gentle cleansers and targeted treatments can help regulate oil, reduce congestion, and support clearer-looking skin.
Why does skin feel dry even after moisturizing?
This usually indicates dehydration or a compromised skin barrier rather than a lack of moisturizer. Over-cleansing, harsh ingredients, or environmental factors can strip the skin of moisture. Using hydrating products that support the skin barrier can help improve moisture retention and overall comfort.
How can sensitive skin be protected from irritation?
Sensitive skin is more reactive to external triggers such as fragrances, alcohol, and strong active ingredients. Choosing gentle formulations with soothing ingredients and avoiding over-exfoliation can help calm the skin, reduce redness, and strengthen its natural protective barrier over time.
What helps improve dull skin and fine lines?
Dullness and fine lines are often linked to dehydration, sun exposure, and slower skin renewal. Products rich in antioxidants, hydrating ingredients, and gentle exfoliants can help improve skin texture, boost radiance, and support a smoother, more refreshed appearance with consistent use.
How can a simple skincare routine be built?
A simple routine focuses on essential steps: cleansing to remove impurities, moisturizing to maintain hydration, and sun protection to prevent damage. Targeted treatments can be added gradually based on specific skin concerns, helping maintain results without overwhelming the skin.
