How to use retinoids in an anti-ageing skincare routine
Published on 06 August 2026Retinoids are among the most extensively researched ingredients used in cosmetic skincare for visible signs of skin ageing. By supporting the skin's natural renewal process, they can gradually improve the appearance of fine lines, wrinkles, uneven tone and rough texture.1-4
However, an effective anti-ageing routine should not rely on a retinoid alone. Skin ageing reflects several overlapping processes, including changes to the skin barrier, oxidative stress and cumulative ultraviolet (UV) exposure. A balanced routine should therefore support the barrier, provide antioxidant protection, encourage renewal and protect the skin from any further sun-induced damage.1,5-11
In this article we explain where a retinoid fits within a dermatologist-aligned morning and evening routine, which ingredients can complement it and how to build tolerance without unnecessarily overloading the skin.
Four pillars of a dermatologist-aligned anti-ageing routine
The most effective routine is not necessarily the one with the greatest number of products. It is one that addresses the main factors influencing visible skin ageing while remaining comfortable enough to follow consistently.
1. Support the skin barrier
The skin barrier helps retain moisture and protects against external irritants. Barrier-supporting ingredients such as niacinamide, ceramides and hyaluronic acid can help maintain hydration, resilience and comfort - particularly while the skin is adapting to a retinoid.6-9
2. Provide daily antioxidant support
Environmental stressors, including UV exposure and pollution, contribute to oxidative stress. Antioxidants such as vitamin C, vitamin E and ferulic acid help neutralise free radicals and complement daily sunscreen within a preventative morning routine.10,11
3. Encourage targeted skin renewal
Retinoids support the skin's natural renewal process and can improve several visible signs of ageing over time. Other renewing ingredients, including alpha hydroxy acids (AHAs), may also have a role, but they should be introduced carefully to avoid unnecessary irritation.1-4,12
4. Protect against UV-induced damage
Daily broad-spectrum photoprotection is essential. UV exposure is a major external contributor to premature skin ageing and uneven pigmentation, so sunscreen helps protect the progress that the rest of the routine is designed to support.5
Morning routine: Protect and support
Although retinoids are usually applied in the evening, the morning routine is equally important. Daytime skincare should support the skin barrier and help defend against the environmental factors that contribute to visible skin ageing.
Step 1. Cleanse
Use a cleanser that removes overnight sweat, oil and product residue without leaving the skin tight or uncomfortable such as the ENDOCARE Aquafoam Gentle Cleansing Wash. If your skin is adjusting to a retinoid or feels sensitive, avoid adding scrubs or several separate exfoliating steps at the same time.
Step 2. Apply an antioxidant serum
Antioxidants and retinoids have different but complementary roles. Retinoids support renewal in the evening, while antioxidants help protect the skin from oxidative stress during the day. Vitamin C is one of the most extensively studied topical antioxidants and can also help improve the appearance of uneven tone.10,11
Within ENDOCARE RADIANCE, C Ferulic Serum Gel is positioned for daily antioxidant support and contains 5% pure vitamin C alongside ferulic acid, vitamin E and EDAFENCE® Technology. Meanwhile the ENDOCARE Vitamin C20 Serum combines 5% pure vitamin C with 15% stabilised vitamin C in AOX-TECH nanovesicles for a more intensive antioxidant approach to visibly photodamaged skin.
Step 3. Moisturise as needed
A moisturiser can help maintain hydration and support barrier comfort, particularly during the first weeks of retinoid use. Look for a texture that suits your skin type and contains hydrating and barrier-supporting ingredients such as hyaluronic acid, niacinamide or ceramides.6-9
ENDOCARE AGE BARRIER Hyaluboost Gel Cream is a lightweight option formulated with hyaluronic acid, niacinamide and EDAFENCE® Technology to support hydration and barrier resilience.
Step 4. Finish with broad-spectrum sunscreen
Sun protection is the final and most important step in the morning routine. UV exposure contributes to wrinkles, loss of elasticity and uneven pigmentation, while daily sunscreen helps protect against further sun-induced damage.5 Apply a high-level, broad-spectrum sunscreen every morning.
The HELIOCARE 360° range provides very high-level, full-spectrum protection against UVB, UVA, visible light and infrared-A in a choice of formulations for different skin types and preferences. Reapply according to the product directions during prolonged outdoor exposure and after swimming, sweating or towel drying, and combine sunscreen with shade, protective clothing, sunglasses and a hat.
Evening routine: Cleanse, renew and support
The evening routine is the most appropriate place for a retinoid. Keeping the surrounding steps simple can make it easier to build tolerance and use the product consistently.
Step 1. Cleanse thoroughly but gently
Remove sunscreen, makeup, excess oil and daily impurities without over-cleansing. Harsh cleansers and repeated exfoliation can increase discomfort when a retinoid is first introduced.
ENDOCARE HYDRACTIVE Micellar Solution is a no-rinse option designed to remove makeup and impurities while supporting skin comfort. Follow with the ENDOCARE Aquafoam Gentle Cleansing Wash for a deep cleanse.
Step 2. Apply your retinoid
Apply the amount stated in the product directions to clean, dry skin. For a facial serum, a pea-sized amount is generally sufficient for the face. Avoid applying extra product to individual lines or areas of concern: more product will not produce faster results and is more likely to increase irritation.2,3,13
When beginning a new retinoid, start with a low frequency and increase only when the skin remains comfortable. Consistency over time is more important than progressing to daily use as quickly as possible.
Step 3. Follow with moisturiser
A moisturiser can help reduce dryness and support the skin barrier while tolerance develops. Most people apply it after the retinoid. For sensitive skin, applying moisturiser before and after the retinoid - sometimes called the sandwich method - may improve comfort, provided this is consistent with the product directions or professional advice.8,13

Support gradual skin renewal while maintaining hydration and comfort. |
Why retinoid formulation matters
The retinoid name or percentage does not tell the whole story. Retinol and retinal are sensitive to light, air and heat, and retinal is particularly reactive. Packaging, stabilisation, encapsulation, product texture and the supporting ingredients all influence how well the formula performs and how comfortably it can be used.2,3
Advanced delivery systems can protect a retinoid within the formula and release it in a more controlled way. Hydrating and barrier-supporting ingredients can further improve comfort. This is why a well-formulated product that can be used consistently may be more appropriate than simply choosing the highest percentage available.
Within ENDOCARE RENEWAL, RETINDUO® Technology is used to improve the appearance of visible signs of skin ageing. It combines pure retinol in Microsponges with retinal in AOX-TECH nanovesicles, supported by a targeted natural booster complex to optimise retinoid stability and delivery.
The progressive ENDOCARE RENEWAL retinoid options include:
ENDOCARE RENEWAL Retinoid Serum - RETINDUO® Potency Level 1, designed for those introducing advanced retinoid skincare or targeting earlier visible signs of skin ageing.
ENDOCARE RENEWAL Retinoid Intensive Serum - RETINDUO® Potency Level 2, developed for skin already accustomed to retinoids and seeking a more intensive cosmetic renewal approach.
These potency levels are specific to the RETINDUO® system and should not be interpreted as a universal strength scale across unrelated retinoid products. Progression should always be guided by skin tolerance and the product directions.
How to introduce a retinoid gradually
The adjustment period that can occur when a retinoid is first introduced is often called retinisation. Temporary dryness, tightness or light flaking may occur, but irritation is not evidence that the product is working. A gradual introduction helps the skin adapt while making the routine easier to maintain.1-3,13
| Stage | Suggested frequency | What to look for |
|---|---|---|
| Weeks 1-2 | Two evenings per week. | Keep the rest of the routine simple and monitor dryness, redness and comfort. |
| Weeks 3-4 | Increase to alternate evenings only if comfortable. | Maintain moisturiser and daily sunscreen; reduce frequency if irritation persists. |
| Week 5 onwards | Increase in line with tolerance and product directions. | Nightly use is not essential for everyone. Use the highest frequency your skin can tolerate comfortably. |
This schedule is a general framework rather than a rigid rule. Some people need longer at each stage, while others may remain on two or three applications per week. Reduce use if dryness or redness becomes persistent. Stop and seek professional advice if you experience marked burning, swelling, blistering or a significant flare of an existing skin condition.
Which ingredients can be used with retinoids?
Retinoids do not need to be used in isolation. Complementary ingredients can support hydration, antioxidant protection and barrier comfort, but the routine should be built gradually so you can identify how your skin responds.
| Ingredient | How to use it | Why it can complement a retinoid routine |
|---|---|---|
| Vitamin C | Usually in the morning | Provides antioxidant support and can help improve the appearance of uneven tone.10,11 |
| Niacinamide | Morning and/or evening | Supports barrier function, hydration and overall skin comfort.6 |
| Hyaluronic acid | Morning and/or evening | Helps attract and retain moisture, which can be useful during retinisation.9 |
| Ceramides | Morning and/or evening | Help support the skin barrier and reduce moisture loss.8 |
| Peptides | According to product directions | Can support skin conditioning within a broader anti-ageing routine. |
| AHAs or BHAs | Introduce with caution | They may complement renewal but can increase irritation when layered as separate high-strength products. Professionally formulated combinations should be used according to their directions.12 |
Introduce one new active at a time. If your skin is still adapting to a retinoid, prioritise cleanser, moisturiser and sunscreen before adding separate exfoliating acids or several intensive serums.
Common retinoid routine mistakes
Most problems arise from progressing too quickly or combining too many potentially irritating steps. Common mistakes include:
- Applying more than the recommended amount in the hope of faster results.
- Starting with nightly application rather than building frequency gradually.
- Moving to a higher-strength formula before the skin has adapted to the current one.
- Introducing several exfoliating acids or other intensive actives at the same time.
- Skipping daily sunscreen or failing to reapply during prolonged outdoor exposure.
- Assuming peeling is necessary for the retinoid to be effective.
- Ignoring persistent irritation rather than reducing frequency or seeking advice.
Bringing the routine together: The ENDOCARE Approach
A complete anti-ageing routine should support the skin rather than focus on one isolated ingredient. The ENDOCARE Approach brings together complementary steps that can be adapted according to skin type, concerns and tolerance:
| Pillar | Range | Role within the routine |
|---|---|---|
| Support the barrier | ENDOCARE AGE BARRIER | Hydration and barrier support with ingredients such as niacinamide and hyaluronic acid. |
| Provide antioxidants | ENDOCARE RADIANCE | Daytime antioxidant support with vitamin C and complementary antioxidant technologies. |
| Encourage renewal | ENDOCARE RENEWAL | Targeted renewal for visible signs of skin ageing, including RETINDUO® retinoid formulations. |
| Protect every day | HELIOCARE 360° | Very high-level, full-spectrum photoprotection to help defend against UVB, UVA, visible light and infrared-A. |
The aim is not to use every product immediately. Choose the steps that address your skin's current needs, introduce actives gradually and maintain the routine consistently over time.
When to seek professional advice
Retinoids are not suitable for everyone. As a precaution, they are generally not recommended during pregnancy or while breastfeeding unless a qualified healthcare professional has specifically advised otherwise. People with active eczema, a rosacea flare, ongoing irritation or a significantly weakened skin barrier should seek advice before starting.2,13
Retinoids can be a valuable part of an anti-ageing routine for adults with acne-prone skin, helping to improve the appearance of fine lines, uneven texture, congestion and post-blemish marks. However, if cosmetic retinoids are not helping to settle persistent flare-ups, or the acne is painful, inflammatory or beginning to scar, seek advice from a GP, pharmacist or dermatologist. In these cases, medical assessment and a prescribed treatment, which may include a topical retinoid such as tretinoin where clinically appropriate, may be needed. Cosmetic skincare can support the routine, but it should not replace medical treatment for persistent or severe adult acne.
In conclusion
- Retinoids can improve several visible signs of skin ageing, but they work best within a balanced routine rather than in isolation.
- The four priorities are barrier support, antioxidant protection, targeted renewal and daily photoprotection.
- Use antioxidants and sunscreen in the morning, and introduce a cosmetic retinoid gradually in the evening.
- Formulation, delivery technology and skin tolerance matter as much as the retinoid name or percentage.
- Consistent use at a comfortable frequency is more valuable than progressing to the highest strength too quickly.
- Daily high-level, broad-spectrum sunscreen is essential throughout the year.
