The Bakuchiol Booster is a powerful nighttime treatment that delivers all the benefits of retinol—without the irritation. Packed with bakuchiol, a natural retinol alternative, this booster promotes the production of collagen types I, III, and IV, helping to reduce the appearance of fine lines and wrinkles. Skin is left looking firmer, smoother, and more radiant with regular use.

This formula also includes soothing vitamin E and nourishing plant oils like chia, marula, squalane, and grape seed to keep skin hydrated, plump, and healthy. Perfect for sensitive skin, it’s gentle enough to use every night, providing all the benefits of retinol without the dryness or sensitivity.

Bakuchiol is a natural alternative to retinol, working by activating skin cell pathways that enhance collagen production, promoting skin health and reducing fine lines effectively. Unlike retinol, it achieves this without causing dryness, irritation, or discomfort, making it ideal for sensitive skin. That’s why the brand has harnessed bakuchiol in their formula, creating the Bakuchiol Booster—studies show it can reduce wrinkle depth by over 20% in just 12 weeks while improving pigmentation, elasticity, and signs of photodamage.

Additionally, this formula is dermatologically approved for sensitive skin, fragrance-free, SLS-free, and free from essential oils. Plus, it's vegan and cruelty-free, offering a gentle and ethical skincare experience. By Sarah was inspired by the personal journey of sisters Sarah and Lauren Murrell. While Lauren recovered from acute myeloid leukaemia, Sarah became both her stem cell donor and skincare saviour. Struggling to find natural, effective products for Lauren’s delicate, post-treatment skin, Sarah created her own – and the brand was born. Today, By Sarah offers restorative, natural, and soothing products, blending nature and science to help your skin look and feel its best.
