What is Retinol and How Does it Work?
Retinol is a vitamin A derivative that can help reduce visible signs of aging when applied topically to the skin. It works by increasing collagen production and promoting skin cell turnover to reveal newer, younger-looking skin underneath.
When you apply retinol products to your skin, the retinol penetrates the outer layers and works to stimulate collagen fibers deep within the dermis layer of your skin. Collagen gives skin its youthful structure and bounce, but collagen production slows down as we age. Retinol signals your skin to make more collagen.
In addition, retinol accelerates the skin cell turnover process. The top layer of skin is constantly shedding dead skin cells and generating new cells from the bottom layer. As we get older, that cell turnover process gets slower, leading to a buildup of dead skin that can look dull and aged. Retinol speeds up cell turnover to keep skin looking fresh.
How Long Does it Take to See Results from Retinol?
Most people start to see some improvement in their skin within 6-12 weeks of beginning to use a retinol cream or serum. However, retinol works gradually and the full effects are usually not apparent until after 3-6 months of consistent use.
When first using retinol, many people go through an adjustment phase during the first 6 weeks where their skin may feel a bit more irritated or flaky than normal. This generally subsides with continued use and should not discourage you. Once your skin adjusts, youll really begin to see refined texture, fewer wrinkles & fine lines, diminished age spots, tightened pores, and an overall healthy glow.
Tips to Adjust to Using Retinol
Since retinol increases your skins cell turnover process, it can initially cause some redness, dryness, peeling, or irritation. This reaction is normal and often called retinization. Here are some tips to get through the adjustment period:
- Start slowly by using retinol every 2-3 days and gradually increase frequency based on your skins tolerance
- Apply only a pea-sized amount smoothed evenly over clean, dry skin
- Avoid the eye area and corners of nose & mouth where skin is most sensitive
- Moisturize well after applying retinol
- Use a mild cleanser and avoid other irritating skin care products while adjusting
- If irritation continues, try buffering by applying retinol after your moisturizer instead of before
How to Choose the Best Retinol Product
With so many retinol products available, it can be tricky to select the right one for your skin. Here is what to look for:
Retinol Concentration
Look for retinol concentrations between 0.1% up to 1% for optimal results and skin tolerance. Lower concentrations around 0.025% can be good for very sensitive skin starting retinol use.
Formula Type
Retinol comes primarily in cream or serum formulas. Creams tend to be thicker and more moisturizing. Lightweight serums can be great for oily skin. Look for formulas with added nourishing ingredients like hyaluronic acid and ceramides to offset retinols drying effects.
Packaging
As an unstable ingredient, retinol breaks down quickly with UV light exposure. Choose an opaque container or tube that protects the product. Dark glass bottles are ideal.
Fragrance & Irritants
Seek fragrance-free options since fragrances can cause irritation. Avoid products with known irritants like alcohol, menthol, peppermint, eucalyptus oil.Price
Effectiveness has little correlation with price point when it comes to retinol. Some luxury brands charge over $100 while you can find great drugstore options for under $20. Focus more on the concentration and formula components than the cost.
Risks & Side Effects of Retinol
Used properly, retinol is generally very safe for most people. But there are still precautions to keep in mind:
Sun Sensitivity
The increased cell turnover caused by retinol leaves skin more vulnerable to UV damage. Its paramount to wear SPF 30 sunscreen daily when using any retinol. Limit direct sun exposure as much as possible.
Irritation
Redness, dryness, flaking, and peeling can happen as skin adjusts during the first few weeks of retinol use. Follow the tips above to minimize discomfort. If problems persist, reduce application frequency or concentration.
Pregnancy Safety
Oral retinoids used for acne treatment have been linked to birth defects. While topical retinols impact the skins surface without bloodstream absorption, its still best to avoid use during pregnancy and breastfeeding.
Who Should Avoid Retinol?
While well-tolerated by most, some people are better off avoiding retinol entirely:
- Pregnant & breastfeeding women
- People taking medications that increase sun sensitivity
- Those with sunburn or windburned skin
- People with eczema or rosacea
- Those getting laser resurfacing skin treatments
- Individuals with very sensitive skin unimproved by buffering techniques
How Does Retinol Compare to Other Anti-Aging Ingredients?
Retinol vs. Hydroxy Acids
Alpha Hydroxy Acids (AHAs) like glycolic & lactic work by exfoliating the skins top layer to reveal fresher skin. Retinol instead kickstarts the cell turnover process deep within the dermis. Together they make an unbeatable combo targeting aging on multiple skin levels. AHAs can help retinol penetrate better.
Retinol vs. Vitamin C
Vitamin C is an antioxidant protecting skin against external aging factors like pollution. Retinol boosts collagen to smooth wrinkles. Since Vitamin C can lose stability when combined with retinol, its best to apply them at alternate times of day. Use Vitamin C in the AM before sunscreen, retinol PM.
Retinol vs. Niacinamide
Also called vitamin B3, niacinamide works by strengthening the skin barrier, reducing water loss, soothing inflammation, and inhibiting pigment formation. While they are great together for most skin types, those with very dry skin may find the combo too drying. Mixing with moisturizer can help.
Retinol vs. Peptides
Peptides are chains of amino acids that help stimulate collagen. However, retinol has a much more dramatic firming effect as it communicates deeper with cells to renew collagen and elastin. Using a peptide serum layered under retinol cream gives skin the antioxidant protection to stay strong.
How to Add Retinol to Your Routine
Ready to reap the amazing benefits of retinol? Heres how to start effectively using it:
1. Select Your Product
Choose a 0.025% to 0.1% retinol cream or serum suitable for your skin type. Sensitive skin may tolerate only a couple times a week initially. Build gradually from there based on tolerance.
2. At Night, Cleanse & Apply
Always apply your retinol product at night. Cleanse skin thoroughly and apply to dry face. Use a pea-sized amount pressing gently into skin. Avoid the eye area and corners of nose and mouth.
3. Moisturize Well After
Follow retinol with your favorite facial moisturizer or a specialized product designed to offset retinol drying effects. This buffering trick also reduces irritation for sensitive skin types.
4. Use SPF Religiously
Because retinol makes your skin more sun-sensitive, daily SPF use is mandatory. Opt for a broad spectrum formula with at least SPF 30. Reapply every 2 hours with sun exposure.
Give your skin about 3 months for full retinization results. Be diligent, go slow, and moisturize well. Soon youll be enjoying beautiful skin boosted collagen, accelerated cell turnover, and fewer visible aging signs with retinol!
