Elm Biosciences A3O Elemental Serum vs BOOST LAB Multi-Peptide Anti-Ageing Serum

Pick the Elm A3O if you want a true retinoid night treatment and your skin tolerates retinol; it pairs retinol with bakuchiol, squalane and blue tansy to soften irritation, and owners of similar retinol-bakuchiol creams report smoother texture over weeks. Pick the BOOST LAB Anti-Ageing Serum if you want a lightweight, fragrance-light peptide serum you can layer morning and night and use on the neck; its 4.6 rating from 1,709 buyers backs its quick absorption and firming. The Elm is the stronger anti-aging step; the BOOST LAB is the easier daily hydrator.

• Choose the Elm A3O Elemental Serum if you want an actual retinoid in your night routine and prefer a cream that cushions it with bakuchiol, squalane and blue tansy.
• Choose the BOOST LAB Anti-Ageing Serum if you want a fast-absorbing peptide serum for daily layering, including on the neck, without a retinoid adjustment period.
