Retin-A

Retin-A is a much underutilized topical anti-acne preparation. It unblocks the oily ducts very effectively and is excellent for removing both blackheads and whiteheads. The main problem with Retin-A is that it initially produces some peeling, redness and irritation of the skin. After the first six weeks, however, the skin settles down.

People are often afraid of using Retin-A because of the initial irritation as well as the potential sun sensitivity. Both of these side effects are overstated. If Retin-A is used correctly, under medical supervision, it is a very successful treatment with minimal problems.

Retin-A comes as a cream, a gel or a lotion. The cream is the least irritating and should be used initially. Although the gel is a weaker strength, it is actually more irritating because it has an alcohol base. Individuals with oily skin may eventually use Retin-A lotion, which is the strongest preparation, but should wait until their skin has acclimatized to the cream.

Retin-A may cause initial irritation and even flaring of acne lesions. It takes a minimum of two to three months before any improvement is seen and this continues the longer it is used. However, Retin-A ‘controls’ acne rather than ‘cures’ it and is only effective while it is being used. It is safe to use for prolonged periods.

Although Retin-A does make your skin more sensitive to the sun, this effect has been exaggerated. However, if you are going outdoors for prolonged periods, a non-creamy sunscreen should be worn. Many sunscreens are irritating when Retin-A is being used, so a low irritant sunscreen such as Clinique City Block, Ego SunSense Toddler Milk, Ego Sunsensitive, Roche Aquababy or Koala Beach SPF 15 Gel is best. Alcohol-based sunscreens can sting if used in conjunction with Retin-A.

Topical preparations

Topical antibiotics, in particular clindamycin, erythromycin and lincomycin, are also very useful for acne as they specifically attack the bacteria within the oily glands. These topical preparations are best used in conjunction with benzoyl peroxide or Retin-A and cause few problems and minimal irritation. Not all topical antibiotics are useful as many have no specific action against the offending bacteria.

Some of the old-fashioned anti-acne preparations contain sulphur and salicylic acid. They are still useful but are not as effective as those mentioned above. Topical cortisone preparations are best avoided as they can aggravate acne.

A new preparation, called Ketsugo, seems promising for the treatment of acne. This product is derived from shark oil, and has been developed by Japanese scientists. Although not yet fully evaluated, it appears to reduce oil production and is effective in cases of mild acne.
