Derivative (Actives)
Derivative (Actives) — a modified version of an active ingredient, engineered to improve stability, tolerability, or delivery while retaining the parent ingredient's core function. Derivatives are common with sensitive actives like vitamin C and vitamin A, which may be unstable or irritating in their pure forms.
Key points
- Retinol and retinaldehyde are derivatives that convert to active retinoic acid within the skin.
- Vitamin C derivatives such as magnesium ascorbyl phosphate offer greater stability than pure ascorbic acid.
- Derivatives often require conversion in the skin, which can affect how quickly or strongly they act.
- They are frequently used to reduce irritation while still delivering measurable benefits.
Frequently asked
Why are derivative actives used instead of the original ingredient?
Derivatives can be more stable, gentler, or easier to formulate than pure actives, making them practical when the parent ingredient is unstable or irritating.
Are derivatives less effective than pure actives?
Not necessarily; effectiveness depends on the specific derivative, its concentration, and how well it converts in skin, and some perform comparably to their parent ingredients.
