MEDITHERAPY Retinal Skin Booster Serum 150 ml — Retinaldehyde Hydrating Facial Serum for Fine Lines & Radiance

MEDITHERAPY Retinal Skin Booster Serum is a daily, beginner-friendly retinaldehyde treatment formulated to improve texture, hydration, and visible signs of aging with minimal irritation.

This hydrating K-Beauty facial serum combines a liposome-encapsulated retinaldehyde with niacinamide and a Centella-rich Cica Biome Complex to deliver bioavailable retinal faster than retinol while supporting the skin barrier. Packaged in a generous 150 ml (5.07 fl oz) bottle, the formula is designed for face, neck and body use, offering a value size that encourages consistent application and noticeable refinement of skin tone and texture over time.

How does retinaldehyde differ from retinol for everyday use?

Retinaldehyde requires only one biochemical conversion to become active in the skin, so it can act faster at lower concentrations than retinol. MEDITHERAPY uses liposome-encapsulation to improve delivery into pores and reduce surface irritation, allowing daily use without the typical flaking or purging associated with higher-strength retinoids.

• Faster activation than retinol due to single-step conversion
• Liposome-encapsulation enhances penetration and tolerability
• Formulated at a gentle, beginner-safe concentration for daily application

What skin concerns will this serum help address?

This serum targets uneven texture, fine lines, dullness, and enlarged-looking pores while also supporting hydration and barrier resilience. The combination of retinaldehyde, niacinamide and Centella extracts helps refine skin surface and promote a more even, radiant appearance when used consistently.

• Refines texture and smooths the look of fine lines
• Minimizes the look of pores and evens skin tone
• Deeply hydrates and supports a stronger skin barrier

Is this product safe for sensitive or acne-prone skin?

MEDITHERAPY’s formula is fragrance-free, non-comedogenic, and clinically tested with an irritation index designed to be beginner-friendly. The Cica Biome Complex with multiple Centella Asiatica extracts and niacinamide helps soothe and rebuild the skin barrier, making the serum suitable for many sensitive and acne-prone users when introduced properly.

• Fragrance-free and non-comedogenic to reduce irritation risk
• Cica Biome Complex and niacinamide support barrier repair
• Clinically tested for low irritation; follow patch test and usage guidelines

How should I use this 150 ml bottle for best results?

The large 5.07 fl oz size is intended for daily face, neck, and body use so you can maintain consistent application. Apply generously after cleansing, use SPF in the morning, and follow with a moisturizer; treat it like a foundation step in your routine for ongoing improvement.

• Apply to clean skin day and night; use sunscreen during daytime
• Focus on areas of concern—around eyes, mouth, neck and body rough spots
• Follow with moisturizer; patch test if you have a history of sensitivity

Who is this for? MEDITHERAPY Retinal Skin Booster Serum is aimed at anyone seeking a gentler yet effective retinal option—people new to retinoids, those with sensitive or acne-prone skin looking for a low-irritation alternative, and users who want a value-sized product to treat face, neck and body consistently. If you want the anti-aging benefits of retinaldehyde combined with barrier-supporting niacinamide and Centella extracts, and prefer a fragrance-free, non-comedogenic formula in a large format, this serum is designed to fit into daily skincare routines while minimizing common retinoid side effects.
