Original Abstract of the Article

Major Research Findings

Tretinoin is an oral retinoid used to treat severe, recalcitrant nodulocystic acne. 21 It works by reducing sebaceous gland size and sebum production, thus altering skin surface lipid composition. 21 Using tretinoin for 1-2 mg/kg/day for 3-4 months results in 60%-95% clearance of inflammatory lesions in patients with acne. 21 Doses as low as 0.1 mg/kg/day have also been proven successful in the clearance of lesions. 21 Encouraging results have also been seen in small numbers of patients with rosacea. 21 Side effects affecting the mucocutaneous system and raised serum triglyceride levels occur in most patients receiving tretinoin. 21 Tretinoin is strictly contraindicated in women of childbearing potential. 21

Reasons for Side Effects

Tretinoin is a retinoid derivative, and it has the effect of promoting cell growth and differentiation. 21 This effect is thought to accelerate skin turnover and cause side effects such as dryness and peeling. 21 Additionally, tretinoin reduces sebaceous gland size and sebum production, which can lead to dryness due to insufficient sebum. 21 Furthermore, tretinoin can cause photosensitivity. 21 This is because tretinoin has the effect of promoting melanin production in the skin. 21

Common Side Effects

Dryness

Tretinoin can cause dryness and peeling by accelerating skin turnover. 21 It is important to use a moisturizer thoroughly when using tretinoin. 21

Redness

Tretinoin can cause skin inflammation. 21 When using tretinoin, steroid ointments may be used in combination to reduce inflammation. 21

Peeling

Tretinoin can cause skin peeling by accelerating skin turnover. 21 It is important to use a moisturizer thoroughly when using tretinoin and consult a doctor if peeling is severe. 21

Photosensitivity

Tretinoin can cause photosensitivity. 21 When using tretinoin, be sure to use sunscreen and avoid going out during peak sunlight hours. 21

Other

In addition to the side effects listed above, tretinoin can cause side effects such as dry lips, blurred vision, fatigue, nausea, and vomiting. 21 Be aware of these side effects when using tretinoin. 21

Side Effects Countermeasures

Dryness Countermeasures

It is important to use a moisturizer thoroughly when using tretinoin. 21 Use a moisturizer before using tretinoin, after using it, or both. 21 Moisturizers containing ceramides are particularly effective. 21

Redness Countermeasures

When using tretinoin, steroid ointments may be used in combination to reduce inflammation. 21 Use a steroid ointment before using tretinoin, after using it, or both. 21 Use steroid ointments as directed by your doctor. 21

Peeling Countermeasures

When using tretinoin, use a moisturizer thoroughly, and consult a doctor if peeling is severe. 21 If peeling is severe, you may need to temporarily stop using tretinoin. 21

Photosensitivity Countermeasures

When using tretinoin, be sure to use sunscreen and avoid going out during peak sunlight hours. 21 Choose sunscreen with an SPF of 30 or higher and a PA++ rating or higher. 21 When using tretinoin, be sure to apply sunscreen before going out and reapply it frequently after going out. 21

Comparison Between Studies

Commonalities Between Studies

Many studies have shown that tretinoin is an effective drug for treating acne. 21 Many studies have also shown that tretinoin can cause side effects such as dryness and peeling by accelerating skin turnover. 21

Differences Between Studies

The severity of tretinoin side effects varies depending on the study. 21 This is thought to be due to differences in the age and gender of patients participating in the study, the severity of acne, and the amount of tretinoin used. 21

Cautions for Real-Life Applications

Tretinoin is an effective drug for treating acne, but it also carries the risk of side effects. 21 Follow your doctor's instructions when using tretinoin and be aware of side effects. 21 Also, tretinoin is absolutely contraindicated in women of childbearing potential. 21 If you are planning to become pregnant, stop using tretinoin. 21

Limitations of Current Research

There is still much that we do not know about tretinoin side effects. 21 Further research is needed to better understand tretinoin side effects. 21

Future Research Directions

The development of new drugs and treatment methods to reduce tretinoin side effects is needed. 21 Research to investigate tretinoin side effects in more detail is also needed. 21

Conclusion

Tretinoin is an effective drug for treating severe, recalcitrant nodulocystic acne, but it carries the risk of side effects. 21 Follow your doctor's instructions when using tretinoin and be aware of side effects. 21 Also, tretinoin is absolutely contraindicated in women of childbearing potential. 21
