Choose the skin renewal serum 50ml that matches your skin goals with its active ingredients. If you’re aiming to improve texture and brightness, consider a powerful exfoliant like Medix-5-5 20% AHA Renew Booster Serum 50ml, and start slowly to assess tolerance. For calmer, oil-prone or blemish-prone skin, look at Niacinamide 10% + Zinc 2% options from QX5+ Skin Defence lines, which help regulate sebum and support barrier health. Always patch test and introduce one product at a time, then layer sunscreen during the day.

A 20% AHA concentration delivers stronger exfoliation to remove dull surface cells and refine texture. It works best on skin that can tolerate active ingredients and is typically used on the face with gradual frequency. Start with once or twice weekly and increase only if your skin shows no signs of irritation, always followed by sunscreen during the day. In this listing, Medix-5-5 20% AHA Renew Booster Serum 50ml is an example of this potent option.

Beginners should start with gentler Niacinamide 10% + Zinc 2% for oil control and barrier support to avoid irritation. Pros or experienced users may opt for the 20% AHA Renew Booster Serum 50ml with careful scheduling and monitoring. Do not mix the strong exfoliant with other potent actives at the same time, and always pair with sunscreen.

Patch test any new serum and introduce one product at a time to gauge tolerance. Apply after cleansing and toning, before moisturizers, and use sunscreen in the daytime when any exfoliating serum is active. Store the serum in a cool, dry place away from direct sunlight. If you use an AHA product, consider limiting daytime use or ensuring robust sun protection, and avoid stacking too many active ingredients at once.

This listing includes exfoliating options like Medix-5-5 20% AHA Renew Booster Serum 50ml for texture and brightness, and barrier-friendly options like QX5+ Niacinamide 10% + Zinc 2% Skin Defence Face Serum 50ml and Glowing variants for oil control and blemish support. There is also a brightening option like QX5+ Hello Fairness Alpha Arbutin Brightening Facial Serum 50ml. Each targets different results: resurfacing, barrier health, oil balance, or brightening, so pick based on your primary skin concern and tolerance.

Start with cleansing, then apply a toner if you use one, followed by the skin renewal serum 50ml. If using an exfoliating serum (such as the 20% AHA option), apply it before moisturizer and save heavy creams for after. Finish with a moisturizer and a broad-spectrum sunscreen in the morning, and consider using the AHA product mainly at night to reduce sun sensitivity. If you’re stacking Niacinamide serums, apply them in either order as directed and avoid overloading with actives.
