Building a Skincare Routine: A Practical Guide

Why Routine Matters More Than Products

With thousands of skincare products on the market — and no shortage of conflicting advice online — building a routine can feel overwhelming. But the truth is that a consistent, simple routine often outperforms a complicated one. The most effective approach is to focus on a few proven steps, apply them consistently, and build slowly over time. Whether you are incorporating a prescription retinoid from a telehealth provider or sticking with over-the-counter products, the fundamentals remain the same.

The Core Steps: Cleanser, Treatment, Moisturizer, Sunscreen

At its most basic, an effective skincare routine involves four steps. In the morning: cleanse, apply any daytime actives (like vitamin C), moisturize, and finish with sunscreen. In the evening: cleanse, apply your treatment product (like tretinoin or retinol), and moisturize. Everything else — serums, toners, essences, masks — is optional layering that can be added over time if desired, but the core four steps cover the essentials.

1. 1.Cleanser: A gentle, non-stripping formula. If your skin is not oily in the morning, rinsing with water alone may be sufficient.
2. 2.Vitamin C serum (optional): May help with brightening and antioxidant protection. Apply to clean, dry skin before moisturizer.
3. 3.Moisturizer: A lightweight, hydrating formula suited to your skin type. Look for ingredients like hyaluronic acid, ceramides, or niacinamide.
4. 4.Sunscreen: Broad-spectrum SPF 30 or higher. This is the single most important anti-aging step in any routine. Apply generously and reapply if spending extended time outdoors.

1. 1.Cleanser: Remove sunscreen, makeup, and daily buildup. A double cleanse (oil-based followed by water-based) can be helpful if you wear sunscreen or makeup.
2. 2.Treatment: This is when you apply your prescription retinoid (tretinoin) or OTC retinol. Apply a thin, even layer to clean, dry skin. Avoid the eye area and corners of the mouth if irritation is a concern.
3. 3.Moisturizer: Apply a richer moisturizer to help offset any dryness from your treatment product. If using the sandwich method, apply moisturizer both before and after your retinoid.

Ingredient Interactions: What to Avoid Combining

Not all active ingredients play well together. When using tretinoin or retinol in the evening, it is generally best to avoid layering other strong actives at the same time. This is especially true during the adjustment period when your skin is most sensitive.

• •Tretinoin + AHA/BHA exfoliants (glycolic acid, salicylic acid): Both increase cell turnover and can cause excessive irritation when combined
• •Tretinoin + benzoyl peroxide: Benzoyl peroxide may degrade tretinoin, reducing its effectiveness. If using both, apply at different times of day
• •Tretinoin + vitamin C: Some people tolerate this combination, but many providers recommend using vitamin C in the morning and tretinoin in the evening to reduce irritation
• •Multiple strong actives at once: Adding too many potent ingredients simultaneously increases the risk of irritation without proportional benefit

Building Up Slowly

One of the most common mistakes in skincare is introducing too many new products at once. If something irritates your skin, you will not know which product is the culprit. A better approach is to introduce one new product at a time, use it consistently for at least two weeks, and then evaluate how your skin responds before adding anything else. This is especially important when starting prescription retinoids, which have their own adjustment period.

When to Consider Prescription Skincare

Over-the-counter products can address many skin concerns effectively, especially for younger skin or mild issues. However, if you are dealing with moderate to noticeable fine lines, persistent dark spots, melasma, or texture concerns that have not responded to OTC treatments after several months, prescription-strength options like tretinoin or custom compound creams may offer more meaningful results. Telehealth platforms have made it straightforward to consult a licensed provider and access these treatments without an in-person visit.

The Bottom Line

The best skincare routine is one you will actually follow consistently. Start simple: cleanser, treatment, moisturizer, sunscreen. Add complexity only if your skin needs it and you can commit to using the products regularly. Whether your treatment step is an over-the-counter retinol or a prescription tretinoin from a telehealth provider, the principles are the same — consistency beats complexity, and sun protection is non-negotiable.
