Why customers choose Origin Beauty

Good Molecules Mandelic Acid Serum is a gentle exfoliating serum that combines 10% mandelic acid with phytic acid, gluconolactone, and two sizes of hyaluronic acid to smooth, brighten, and hydrate sensitive skin.

This lightweight 30 ml serum is built to resurface the outer skin layer without harsh irritation. The formula pairs a slow-penetrating AHA (mandelic acid) with a PHA (gluconolactone) and phytic acid to support cell turnover, even tone, and texture while offering immediate and lasting hydration from two molecular weights of hyaluronic acid. Fragrance-free, vegan, and cruelty-free, the serum is formulated at a skin-friendly pH of 4.0 and is intended for regular evening use up to four times weekly or as tolerated.

How does this serum gently exfoliate sensitive skin?

The serum uses mandelic acid, which has a larger molecule size than many AHAs, so it works more slowly and reduces the chance of irritation. Two additional exfoliating agents—phytic acid and gluconolactone—support brightness and moisture while contributing to mild resurfacing.

  • 10% mandelic acid for controlled, gradual exfoliation
  • 1% phytic acid to brighten and provide antioxidant support
  • 1% gluconolactone (a PHA) that exfoliates gently while attracting moisture
  • Formulated at pH 4.0 to balance efficacy and tolerability

Will this serum keep my skin hydrated while exfoliating?

Yes—hydration is a key part of the formula. Two sizes of hyaluronic acid deliver both surface plumping and deeper moisture retention so skin feels smooth, supple, and less tight after use.

  • Low-molecular-weight hyaluronic acid for quick absorption and plumping
  • High-molecular-weight hyaluronic acid for surface hydration and barrier support
  • Hydration helps reduce visible dryness and supports a smoother texture

How should I add this serum to my routine safely?

Introduce the serum gradually: start with one night per week and increase to up to four nights per week as tolerated. Apply a few drops to clean, dry skin in the evening, allow 30 seconds to absorb, then follow with oils, creams, or moisturizers; always patch test first and use sunscreen during the day.

  • Start slow: once weekly, then increase frequency up to four times weekly
  • Use in the evening after cleansing, before heavier moisturizing steps
  • Perform a small patch test before widespread use
  • Apply daytime SPF while using exfoliating acids

Who will see benefits from this Mandelic Acid Serum?

This serum is aimed at anyone seeking a gentle resurfacing option—especially people with sensitive or reactive skin who want exfoliation without aggressive irritation. It also suits those looking to reduce roughness, even skin tone, and maintain hydration. People with very active acne, open sores, or recent retinoid treatments should consult guidance before use.

Good Molecules Mandelic Acid Serum offers a balanced approach: enough strength to promote visible texture and tone improvements, paired with hydrating ingredients and mild PHAs for comfort. It’s a practical addition for sensitivity-prone complexions that still need reliable exfoliation and daily moisture support.
