Retinol reduces the appearance of wrinkles, refines skin texture, and firms the feel of skin. Our retinol serum promotes surface skin cell turnover while strengthening the skin barrier function to better receive optimal effects of our Retinol-enriched formula and visibly renew skin for younger-looking results.

The term Retinoid refers to any Vitamin A derivative. Therefore, Retinol is just one of many types of Retinoid.

Starting retinol is simple with our gentle formula. Our micro-dose retinol serum easily integrates into a skincare routine, suitable for nightly use from day 1. However, if you are new to retinol products and want to err on the side of caution, patch test to make sure it doesn't irritate your skin and then build up your tolerance gradually, applying once or twice a week to start with.

Yes, always use an SPF in the daytime, we recommend our Better Screen™ UV Serum Sunscreen.

After cleansing, apply Retinol Skin-Renewing Daily Micro-Dose Serum over the entire face at night-time, including the under eye and crow's feet area, carefully avoiding contact with the eye and eye lid area.

Our formula is suitable for daily use but if you do find it uncomfortable, reduce frequency of use until your skin has acclimatised.

Avoid using retinol with other potent active ingredients in the same routine. We recommend not combining your retinol serum with AHAs (like glycolic acid), BHAs (like salicylic acid), benzoyl peroxide, or vitamin C in the same application. These combinations can increase irritation and compromise your skin barrier. Instead, use these actives on alternate evenings or at different times of day. Our Micro-Dose formula is designed to work gently on its own, and we recommend pairing it with hydrating products like our Ultra Facial Cream for best results.

Our Micro-Dose Anti-Aging Retinol Serum is ideal for mature skin. This anti-aging retinol serum combines Pure Retinol with Ceramides and Peptides to visibly reduce wrinkles, firm skin, and even skin tone, all concerns that become more prominent with age. The micro-dose formulation delivers potent results while minimising irritation, making it suitable for daily use on mature skin that may be more sensitive. For comprehensive anti-aging benefits, pair with our Super Multi-Corrective Cream, which features Phytomimetic Vitamin A to further smooth fine lines and improve firmness.
