The retinoid family comprises of Vitamin A (retinol)and its natural derivatives including retinaldehyde, retinoic acid and other synthetic derivatives. The actual powerhouse of skincare routine.
Aging is a biologic decomposition at cellular level causing decrease in cellular capacity, cumulative damage of protein and gene result in compromised function and detoriation.
Skin aging could be due to external and internal factors including environment and professional exposure (UV radiation or mechanical stress) and genetics, hormonal changes and metabolic processes. Intrinsic or chronological aging is basically increase epidermal turnover, decrease dermal thickness, decrease mechanical and immune protection causing loss of elasticity. Decrease growth factors causing decreased capacity of proliferation of new cell. This leads to wrinkles formation, hyperpigmentation, furrows, yellow discolouration of skin and comedones formation.
A study conducted in 2004 showed that 4 week treatment with retinol showed improvement in fine wrinkles and hyperpigmentation. It showed clinical improvement at cellular level to reserve photoaging.
Using retinol, a form of vitamin A, in skincare has several proven benefits backed by scientific studies:
1. Reduction of Wrinkles and Fine Lines: Retinol stimulates collagen production, which can improve skin texture and reduce the appearance of wrinkles and fine lines. Studies such as one published in the *Archives of Dermatology have shown its effectiveness in diminishing signs of aging.
2. Improvement in Skin Tone and Texture: Retinol promotes skin cell turnover, leading to smoother, more even-toned skin. Research in the *Journal of Drugs in Dermatology has demonstrated its efficacy in improving skin texture and reducing hyperpigmentation.
3. Treatment of Acne: Retinol is effective in treating acne by unclogging pores and preventing the formation of comedones (blackheads and whiteheads). Studies published in the *American Journal of Clinical Dermatology have shown its effectiveness in reducing acne lesions.
4. Prevention of Photoaging: Retinol has been shown to protect the skin from the harmful effects of UV radiation, such as collagen degradation and DNA damage, thereby preventing premature aging. Research in the *Journal of Cosmetic Dermatology supports its photo-protective effects. Photo-damage is characterised by degeneration of collagen and abnormal deposition of elastic material. Retinol reverse photo-damage in 6 months.
5. *Enhanced Efficacy with Other Skincare Ingredients: Retinol can enhance the effectiveness of other skincare ingredients, such as antioxidants and peptides, by improving their absorption and penetration into the skin. Studies have demonstrated synergistic effects when combining retinol with ingredients like vitamin C and hyaluronic acid.
It’s essential to note that while retinol offers numerous benefits, it can also cause irritation, especially when first starting or if used incorrectly. Gradually introducing retinol into your skincare routine and using sunscreen during the day are recommended practices. Consulting with a dermatologist before starting a retinol regimen is advisable, especially for individuals with sensitive skin or specific skincare concerns.
Best way to apply retinol serum, is to apply 3 times in a week with double coating before application. Double coating of moiustriser before and after retinol application.
