Tretinoin (which is also known as retin-a) is a topical form of vitamin A that reduces the appearance of fine lines, wrinkles and acne and increases skin renewal. It works by stimulating the growth of new cells and unblocking pores to decrease the occurrence of blackheads, spots and pimples. It is also helpful in pre-treating the skin prior to moderate to deep chemical peel, laser treatment, dermabrasion and facelifting to hasten healing and prevent scarring or discolouration.
Unlike the milder retinol creams like retinyl palmitate, tretinoin requires a prescription to be purchased in the UK. This can be obtained from a dermatologist or an online chemist that offers a free consultation. Online chemists are now a much better option as they can process your consultation and prescribe tretinoin much faster than a doctor would be able to.
The most important thing to do when using a retinol is to use it sparingly. You should apply a pea sized amount to clean, dry skin. It is a good idea to cleanse the skin twice a day before applying it and avoid other exfoliators such as AHAs and BHAs as these can cause irritation. You should also skip other treatments or serums that are known to produce irritation, such as toners, vitamin C, other anti ageing serums and anti inflammatory creams. They can be reintroduced later once the skin has become tolerant to the retinol.
It is also important to use a good moisturiser with a broad spectrum SPF during the day. A moisturiser such as the Cerave Lotion or Cetaphil is a good choice.retin a uk
