Tretinoin is an effective skin treatment that helps to reduce acne, fine lines and dark spots. It speeds up new skin cell growth, removing dead cells and preventing them from blocking pores. It also boosts collagen; a protein that acts like scaffolding for the skin, helping to smooth and firm it.

Tretinoin can also improve the appearance of dark spots or hyperpigmentation caused by sun damage, scarring or other factors. It works by increasing skin cell turnover and reducing the production of melanin; the pigment that gives your skin its colour.

It is important to use tretinoin correctly in order to get the best results. Your Obagi skin care nurse will recommend a cream or gel formula that is right for your skin type and condition.

If you have rosacea or other underlying skin conditions that cause sensitivity you may need to be more careful about using tretinoin. These conditions can cause redness and inflammation and you may find that you need to apply tretinoin in small amounts at first and then gradually increase your dose.

Tretinoin is available in the UK by prescription only. You will need to have a consultation with your GP or dermatologist to discuss whether this is the right treatment for you. Some online skincare companies sell tretinoin products in the UK but it is important to only purchase from reputable websites such as Obagi Systems and their authorised stockists. Ketrel is a brand that offers tretinoin in the UK and has been approved by the UK pharmaceutical authority (MHRA). Only a pea-sized amount should be applied to the face, avoiding the eyes and corners of the nose. If you experience any allergic reaction, seek immediate medical attention. tretinoin gel uk
