Description
A-ret (Tretinoin) 0.05% gel
A-ret 0.05% gel is a topical prescription medicine containing tretinoin, a retinoid used in the management of acne vulgaris. It is applied to the skin and is intended for local use only.
Active Ingredient and Medicine Class
The verified active ingredient is tretinoin 0.05%. Tretinoin is a topical retinoid, also known as all-trans-retinoic acid. This class is widely used in acne treatment because it helps normalise skin cell turnover and reduce clogged pores.
Established Medical Uses
Official prescribing information identifies tretinoin gel as a topical treatment for acne vulgaris. Human clinical evidence supports its use for mild to moderate acne, with benefit on both inflammatory and non-inflammatory lesions.
How It Works
Tretinoin acts on the skin’s outer layers to promote more normal shedding of skin cells and reduce the formation of comedones. In acne, this helps prevent pore blockage and supports clearer skin over time. Published reviews also describe anti-inflammatory activity as part of its acne benefit.
Important Safety Information
Tretinoin gel should not be used on eczema or sunburned skin because it may cause marked irritation. It may increase sensitivity to sunlight, so sun exposure can worsen irritation. Caution is also advised when it is used with other topical acne products, medicated cleansers, alcohol-based products, astringents, or other drying or irritating skin products, because these can increase skin irritation. The U.S. label also notes caution in people with fish allergy because some formulations contain fish-derived ingredients.
Possible Side Effects
The most commonly reported adverse effects are dry skin, peeling or flaking, skin burning, and redness. Irritation, stinging, and increased sensitivity to sunlight may also occur. Serious allergic reactions are uncommon but possible; symptoms such as hives or itching should be medically assessed.
Scientific Evidence
Clinical studies and systematic reviews show that topical tretinoin is more effective than vehicle for acne improvement and can reduce lesion counts. A combined analysis of two randomized studies of tretinoin gel 0.05% found it to be effective and generally well tolerated in acne vulgaris. Review literature also supports tretinoin’s long-standing role in acne treatment.
