MEDITHERAPY Retinal Skin Booster Serum Review

Why we recommend it

This facial serum features retinaldehyde, a gentler retinoid alternative, paired with niacinamide to help minimize the appearance of fine lines while supporting skin's overall texture and luminosity. The formula is designed to provide hydration alongside active ingredients, making it suitable for various skin types when introduced gradually.

• Contains retinaldehyde, a gentler retinoid derivative
• Includes niacinamide for skin texture support
• Hydrating serum formula
• Large 5.07 fl oz size for extended use

Who this is for

Most skin types when introduced slowly, particularly those new to retinoids or seeking a gentler alternative to retinol.

Who should skip it

Those with known sensitivities to retinoids, during pregnancy or breastfeeding, or anyone seeking immediate dramatic results.

What to watch out for

Initial adjustment period may include mild irritation or dryness as skin adapts to retinaldehyde, and results develop gradually over weeks to months.
