What the gurus are saying
This serum delivers visible smoothing and a glow within minutes, though it runs stronger and lower in pH than some gurus think necessary for lactic acid to work. Most reviewers praise how gentle it is for sensitive and mature skin, and many return to it repeatedly, especially those nervous about starting exfoliating acids. A few note it can be potent, so patch testing first is wise if your skin is easily irritated. One expert flagged that it may occasionally cause chapped lips and another cautioned about arnica content, though most found it leave skin soft and refined rather than over-exfoliated.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.
Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.
Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
