What is Tretinoin?
Tretinoin is a member of vitamin A group. Also known as all-trans retinoic acid, it is the most potent form of vitamin A. Tretinoin is often used topically for the treatment of acne, wrinkles and hyperpigmentation. It is particularly effective at a 0.3% concentration.
The Benefits of Tretinoin
- Tretinoin has been proven to be effective for the treatment of acne. A study involving 577 people showed that tretinoin reduces the acne inflammation.
- Tretinoin effectively reduces hyperpigmentation spots.
- Tretinoin boosts the collagen synthesis in the skin and reduces the appearance of wrinkles and lines.
The Commonly-Known Side Effects of Tretinoin
- Similar to retinol, tretinoin increases the risk of UV-induced skin damage including skin cancer. Studies showed that at a 0.05% concentration or higher, tretinoin increases the phototoxicity of UV light.
- Tretinoin is commonly known to cause excessive peeling, skin dryness and hypersensitivity.
- Tretinoin should only be used under the supervision of a dermatologist as some of its side effects can be very serious.
The Alternative to Tretinoin
Some skincare ingredients can be as effective as tretinoin in reversing the signs of skin ageing and damage without having commonly-known side effects such as niacinamide, n-acetyl glucosamine, coenzyme Q10 and resveratrol. In facts, these ingredients strengthen skin's defense against UV and environmental damage.
