This retinol serum from numbuzin, part of the No.3 line, is formulated as a gentle entry point for those new to retinol. The product combines blue bio-retinol, a plant-based alternative to traditional retinol, with pore-refining ingredients to support skin texture and firmness. It is designed to help tighten and firm the skin while minimizing the appearance of pores.

The serum includes BHA (beta hydroxy acid) to assist with gentle exfoliation and pore clarity, niacinamide to support skin barrier function and even tone, and peptides to promote a firmer appearance. This blend aims to offer a multi-action approach to skincare without relying on harsh or overly aggressive active levels. The formula is intended to be mild enough for beginners who wish to incorporate retinol-like benefits into their routine with reduced risk of irritation.

Suitable for those with normal, combination, or oily skin types, this serum targets concerns such as uneven texture, enlarged pores, and early signs of laxity. It is not recommended for highly sensitive or compromised skin without prior patch testing. The product has a lightweight, water-like consistency that absorbs quickly without leaving a greasy residue, making it suitable for use under moisturizers or sunscreen during a daytime or nighttime regimen.

Priced for accessibility, this 30ml (1.01 fl. oz) bottle offers a cost-effective option for those exploring retinol-based skincare. The formula is free from artificial fragrances and dyes, focusing on a streamlined ingredient list. As with any active ingredient, gradual introduction and sun protection are advised. This serum is a practical choice for individuals seeking a balanced, non-irritating formula that addresses multiple skin concerns through a single product.
